Overview
NEFF Screw drives
Trapezoidal screw drives
Ball screw drives
NEFF trapezoidal screws are manufactured from special semi-finished goods with high demands on straightness. The series conforms
to DIN 103 and offers an extensive range of nuts made from various
materials – all ready for installation. The very low backlash in the
nuts allows low radial forces to be absorbed.
The range conforms to DIN 69051 and the NEFF standard. All nuts
(flanged and cylinder versions) can be supplied with the corresponding DIN connections. Pre-tensioned double-nut units achieve high
positioning accuracies. Special nuts on enquiry. All ball screw drives
are available with customer-specific end machining.
On request we can supply soft-annealed ends for you to carry out
your own end machining.

Ball screw drive
Ball screw drives from Neff screw drives are the result of many decades of innovative further development of the ball screw drive.
The spindles are available with customised end machining, or on
request with soft-annealed ends for your own machining.
We offer ball screw drives in all common sizes in precision-rolled versions at competitive prices, in extraordinary quality and with a complete
quality concept.
The high mechanical efficiency < 98% requires a lower drive power
and a significantly lower breakaway torque than with trapezoidal screw
drives.
The Neff ball screw range corresponds to DIN 69051 and the NEFF
standard (exchangeability of EFM trapezoidal nuts to ball screw nuts)
Thanks to the low rolling friction and deflection systems that have been
developed further over many years, Neff ball screw drives have a particularly long and reliable service life

General
technical data
Manufacturing process
The thread profile of NEFF ball screws is produced by cold rolling in
the thread rolling method. Both screw and nut have an arched thread
profile. The load angle is 45°.
Neff ball screw profiles
Neff ball screw profiles have a Gothic pointed arch profile with a 45°
contact angle and optimised osculation. (Ratio of ball race radius to ball
diameter)
Linear speeds
At present the permissible speed limit is in the region of 3000 rpm,
with individual dimensions up to 4500 rpm. This limit defines the maximum speed, which may be run only under ideal operating conditions.
Installation position
The position in which the screw drive is installed can always be freely
chosen. Please consider that all radial forces that occur need to be
absorbed by external guides.
Accuracy classes of the spindles
T5 = pitch accuracy 23 μm/300 mm
T7 = pitch accuracy 52 µm/300 mm
T9 = pitch accuracy 130 µm/300 mm
T10= pitch accuracy 200 µm/300 mm
If nothing different is specified we deliver class T7.
Self-locking
Ball screw drives are generally not self-locking due to the low friction. It is
therefore advisable to install suitable motors with holding brake, particularly when the ball screw drive is installed vertically.
Efficiency
Trapezoidal screw drives have a max. mechanical efficiency of 50 %,ball
screw drives achieve a mechanical efficiency of up to 98 %.
Duty cycle
The ball screw drive permits a duty cycle of up to 100 %. Extremely high forces in combination with high duty cycles can shorten the
service life.
Temperatures
All screw drives are designed for continuous operation at ambient
temperatures of –30 °C up to 80 °C. Temperatures of up to 110 °C are
also permitted for brief periods. Ball screw drives are suitable only in
exceptional cases for operation at sub-zero temperatures.
Repeatability
The repeatability is defined as the capability of a screw drive to reach
an actual position again that has been reached once before under the
same conditions. It refers to the average position variation according to
VDI/DGQ 3441. The repeatability is influenced amongst other things by:
nLoad
nSpeed
nDeceleration
n Direction of travel
nTemperature
Neff deflection systems
Single deflection:
In this type of deflection the balls are lifted up out of the spindle after
each circuit and set back by one thread pitch.
(Only for single-start ball screw drives)
Channel deflection:
In channel deflection the balls, after several circuits, are steered by an
integrated deflection piece into a return channel in the nut and fed back
(For single-start and multi-start ball screw drives)
Cover deflection:
In cover deflection the balls are steered via special deflection covers
into the return channel in the nut and fed back.
(For multi-start ball screw drives)
Types of pre-loading:
In principle all Neff ball screw nuts are combinable for a backlash-free, Opre-loaded nut unit if a ball screw drive is selected with a pitch accuracy
of ≤ T7.
With less accurate pitch classes only low-backlash can be set (≥ 0.03mm)
O-pre-loading:
In the O-pre-loading the force lines run with a diamond form, i.e. the nuts
are pressed apart by a specially manufactured intermediate piece.
The standard pre-loading is about 10% of the dynamic load rating Cdyn
Pre-loading by ball selection:
The ball screw nut can be adjusted for low backlash by means of ball
selection.
Aggressive operating conditions
In cases of heavy dirt and fine dust particles/swarf, an additional bellow
or a spiral spring cover is recommended.

Calculation
Ball screw Drive
Required drive torque and drive power
The required drive moment of a screw drive results from the acting
axial load, the thread pitch and the efficiency of the screw drive and its
bearing. In case of short acceleration times and high speeds the acceleration torque must be checked.
Fundamentally it must be noted that trapezoidal screw drives have to
overcome a breakaway torque when starting up.

Fm
Since a ball screw can be loaded in two directions, Fm must
initially be determined for each of the two load directions. The
larger value is then taken for the calculation of L.
In general it is useful to prepare a diagram. In doing so,
remember that any pre-loading represents a constant load.

Types of bearing
Typical values for the correction factor fk according to the classic
installation cases for standard spindle bearings.
Critical buckling force of ball screws
With slim components such as spindles there is a danger of lateral
buckling under axial compressive loads. Using the procedure described
below, the permissible, axial force can be determined according to
Euler. The safety factors applying to the system must be considered
before determining the permissible compressive force.

Critical speed of ball screws
With slim, rotating components such as spindles there is a risk of resonant vibration. The procedure described below enables the resonant
frequency to be estimated, assuming an adequately rigid installation. In
addition, speeds close to the critical speed greatly increase the risk of
lateral buckling. The critical speed must therefore also be considered in
connection with the critical buckling force.

Trapezoidalthreaded nut TGM
Safety trap nut SFM
Safety trap nuts are used wherever increased operational reliability is
demanded and in order to limit the economic damages in case of a nut
breakage.
Safety trap nuts for VBG 14 or VBG 70 requirements on enquiry.
The safety trap nut runs along with the travelling nut without axial load
and thus wear-free. As wear of the travelling nut increases, the distance
X between the two nuts decreases.
The travelling nut must be replaced when the distance X is reduced by
25%.
If the thread turns of, the travelling nut should break through due to
excessive wear, the safety trap nut absorbs the applied load.
The safety trap nut can only be ordered in conjunction with the flange
nut.

Load ratings of trapezoidal screw drives
As a general principle, the load rating of trapezoidal screw drives is
dependent on their material, surface quality, state of wear, surface
pressure, lubrication conditions, running speed and temperature, and
thus on the duty cycle and the provision for heat dissipation.

The permissible surface pressure is primarily dependent on the running

Types of bearing
Typical values for the correction factor fk according to the classic
installation cases for standard spindle bearings.
Critical buckling force of ball screws
With slim components such as spindles there is a danger of lateral
buckling under axial compressive loads. Using the procedure described
below, the permissible, axial force can be determined according to the
Euler-Case. The safety factors applying to the system must be considered before determining the permissible compressive force.

Critical speed of ball screws
With slim, rotating components such as spindles there is a risk of resonant vibration. The procedure described below enables the resonant
frequency to be estimated, assuming an adequately rigid installation. In
addition, speeds close to the critical speed greatly increase the risk of
lateral buckling. The critical speed must therefore also be considered in
connection with the critical buckling force.

Trapezoidal screw drive
Required drive torque and drive power
The required drive moment of a screw drive results from the acting
axial load, the thread pitch and the efficiency of the screw drive and its
bearing. In case of short acceleration times and high speeds the acceleration torque must be checked.
Fundamentally it must be noted that trapezoidal screw drives have to
overcome a breakaway torque when starting up.

Torque due to an axial load
Trapezoidal threads whose pitch angle α is greater than the friction angle ρ’, are not considered to be self-locking. This means that an applied
axial load generates a resulting torque on the spindle. The efficiency
for the transformation of η’ longitudinal motion into a rotary motion is
lower than for the transformation of a rotary motion into a longitudinal
motion.

Installation
and maintenance
Trapezoidal screw drives TGT
Ball screw drives KGT
Installation
Trapezoidal screw drives must be aligned carefully during installation – if
suitable measuring equipment is not available, the screw drive should
be turned through its entire length by hand before the drive unit is
attached.
Variations in the amount of force required and/or marks on the
external diameter of the spindle indicate alignment errors between the
spindle axis and guide. In this case, the relevant mounting bolts should
first be loosened and the screw drive should be turned through by
hand. If the amount of force required is now constant throughout, the
appropriate components should be aligned, otherwise the alignment
error should be localised by loosening further mounting bolts.
Installation
Ball screw drives are precision machine components; their installation
requires specialist knowledge and suitable measuring equipment. Due
to the low friction alignment errors can generally not be felt when the
screw drive is turned by hand. Radial or eccentric forces must be taken
up by external guides. Ball screw drives can absorb only axial forces.
To avoid damage to the ball screw drive, limit switches and end stops
must be installed in the machine.
Cover
By virtue of their design, trapezoidal screw drives are less sensitive to
dirt than ball screw drives, particularly at low speeds (manual operation).
Nevertheless motion drives, especially with plastic nuts, require
protection against dirt in the same way as ball screw drives.
Cover
Dirt that occurs during installation should be removed with paraffin, oil
or petroleum ether. Cold cleaners and paint solvents are not permitted.
Ball screw drives must be protected against dust, swarf, etc. even if
equipped with wipers. Possible protective measures include:
– Bellows (suitable only for vertical installation without additional guide).
– Spiral spring cover.
– Telescopic tubes or sleeves (these take up a lot of axial space).
Lubrication
Lubrication
Oil lubrication
Used only in special cases for trapezoidal screw drives.
Grease lubrication
The usual lubrication method for trapezoidal screw drives. Lubrication
intervals are governed by operating conditions; it is advisable to clean
the spindle before greasing, especially by using high-performance
lubricating machines.
Type of grease: ball bearing grease without solid lubricant. Parts ref.
Neff Grease 2
Operating temperature
This depends on the type of nut used, the lubrication conditions and
the user’s requirements. Please consult us in the case of temperatures
above 100 °C (plastic nuts 70 °C).
Wear
This can be checked manually: the nut should be replaced if the axial
backlash with a single-start screw drive is more than 1/4 of the pitch.
Proper lubrication is important for the achievement of the calculated
service life of a ball screw drive, to prevent excessive warming and to
ensure smooth, quiet running. The same lubricants are used for the
KGT ball screw drives as for roller bearings.
Oil-mist lubrication
In the case of central lubrication with oil mist, note that only ball screw
nuts without wipers may be used.
Oil lubrication
Die zugeführte Ölmenge sollte die Austragsverluste an den Abstreifern
nicht überschreiten. (Sonst Ölumlaufschmierung).
Ölsorten: Viskosität 25 bis 100 mm2/s bei 100 °C.
Grease lubrication
Add grease corresponding to the volume lost via the wipers (under
normal operating conditions, it is sufficient to add grease every 200
to 300 hours). Experience shows that single lifetime lubrication is not
sufficient because of the seepage of grease.
Grease type:
Roller bearing grease with no solid lubricant content. The first fill takes
place at the supplier’s with roller bearing grease. We recommend Neff
Gear Grease 2/3 in the case of high mechanical stresses.
Operating temperature
The permissible operating temperature range for ball screw drives is
between –30 °C and +80 °C, up to +110 °C for brief periods. A precondition for this is correct lubrication. The torque may increase by a factor
of up to 10 at temperatures below –20 °C.

The range includes a total of 11 worm gear
screw jack models in two series: M 0 – M 5
with lifting capacities from 2.5 kN to 100 kN
and J 1 – J 5 with static lifting capacities
from 150 kN to 500 kN.
Stroke speed
Transmission Ratio H (high speed)
Worm gear screw jacks with trapezoidal-threaded spindle produce a
stroke of 1 mm for each full revolution of the worm shaft. Accordingly
the linear speed is 1500 mm per min at 1500 rpm. Worm gear screw
jacks with a ball screw achieve 6000 mm/min, depending on size and
pitch.
Transmission Ratio L (low speed)
Worm gear screw jacks with trapezoidal-threaded spindle produce a
stroke of 0.25 mm for each full revolution of the worm shaft. Accordingly the linear speed is 375 mm per min at 1500 rpm.
Please note that higher speeds of travel can be achieved by using
spindles with larger thread pitches or multi-start threads.
The worm gear screw jack’s maximum drive speed of 3000 rpm must
not be exceeded.
The higher efficiency of the ball screw drive also permits a longer duty
cycle.
Tolerances and backlash
nThe gearbox housings are machined on the six mounting sides.
The tolerances conform to DIN ISO 2768-mH
nThe axial backlash of the jack screw under alternating load is as
follows:
– Trapezoidal-threaded spindles: up to 0.4 mm (to DIN 103)
– Ball screws: 0.07 mm
Worm Gear Screw
Jacks M/J
Self-locking
The self-locking function depends on a variety of parameters:
n High pitches
n Different worm gear transmission ratios
nLubrication
n Friction parameters
nEnvironmental influences, such as high or low temperatures,
vibrations, etc.
n The mounting position
Versions with ball screw and TGS/KGS with high pitches are therefore
not self-locking. Suitable brakes or braking motors must therefore be
used in such cases. Self-locking is only conditionally available for smaller
pitches (single-start). Self-locking in individual cases on enquiry
Version N
The lifting spindle is driven by a nut thread in the worm gear via the
worm shaft. Protection against twisting is achieved by the on-site fastening of the spindle.
Version VK
The lifting spindle is driven by a nut thread in the worm gear via the
worm shaft. Protection against twisting is achieved by a square protective tube on the gear side.
Version VP
The lifting spindle is driven by a nut thread in the worm gear via the
worm shaft. Protection against twisting is achieved by a feather key in
the bearing cover of the gearbox and a milled groove in the spindle.
nThe lateral backlash between the outside diameter of the spindle
and the guide diameter is 0.2 mm.
nThe backlash in the worm gears is ± 4° for transmission ratio L and
± 1° for transmission ratio H based on the drive shaft.
nTrapezoidal-threaded spindles are manufactured to a straightness of
0.3 – 1.5 mm/m, ball screws to a straightness of 0.02 mm/m over a
length of 1000 mm and to the following pitch accuracies:
M 0 – M 5: 0.05 mm/300 mm length
J 1 – J 5: 0.2 mm/300 mm length.
Lateral forces on the screw jack.
Lateral forces can also be absorbed by our screw jacks.
Please contact us.
Version R
The lifting spindle is made to rotate by the worm shaft via the worm
gear with a feather key connection to the spindle.
The rotary motion of the spindle is converted into a linear motion by the
on-site anti-twist securing of the travelling nut.
Anti-unscrewing device A
The anti-unscrewing device prevents the spindle from screwing out of
the gearbox. It is standard equipment in the ball screw versions N and V
and is available as an option in worm gear screw jacks with trapezoidalthreaded spindles.
The anti-unscrewing device cannot be used as a fixed stop.
Special versions
In addition to the extensive standard range, NEFF can also supply
anticlockwise, multi-start and special material worm gear screw jacks
on enquiry.

High Speed Screw Jack G1-G3
NEFF high speed screw jacks supplement our offer of worm gear screw
jacks. They are more efficient and may be used in a broader field of
applications. They may be used in a medium load range (12.3 kN-117 kN1),
with a high lifting speed and longer operating time.
All high speed screw jacks are equipped with hardened, sharpened
and spiral-toothed bevel gear transmissions. Therefore, they attain high
lifting speeds and improved efficiency.
more dynamic. All high speed screw jacks work in all installation
positions. Due to their cubic casing they can be mounted flexibly.
By using ball screws the high-speed screw jacks achieve even better
performance values. All high-speed screw jacks are functional in every
installation position and can be mounted flexibly thanks to the cubic
form of the housing.
According to the customer’s request they are delivered with up to four
drive shafts. Lifting assemblies with several high speed screw jacks do
not therefore require additional bevel gears.
The models N, V and R are available in three sizes with 2:1 and 3:1
transmissions. With ball screws, high speed screw jacks become even

Screw Jacks
The general procedure for the design of
worm gear screw jacks is as follows:
1.Definition of the speed, the required force and the possible installation position of the worm gear screw jack.
2.Selection of the drive elements (couplings, shafts, bevel gearbox,
motors) for the synchronous drive of the individual worm gear
screw jacks. The following criteria are decisive here:
•Lowest possible load on the individual transmission elements.
In particular, the introduction of the total drive torque via the
toothing of a bevel gearbox is to be avoided
•Lowest possible number of transmission elements and short
connecting shafts.
•Device for the protection of the unit by torque-limiting coupling.
Selection of a worm gear screw jack and the associated drive
Axial load F=kN
Critical buckling force? see pages 78-80
Speed v = m/min (only version R)
Critical speed? see pages 78-80
Duty cycle? DC = % in 1hr
see pages 62-64; 70-72
Select gearbox size
Calculate or look up required drive torque
see page 81
Check permissible drive torque
Check lateral forces acting on the spindle as well as axial and
radial forces acting on drive shafts
(avoid lateral forces on spindle = guide)
Calculate necessary drive power in KW (observe breakaway torque)

Note: Forces and torques can only be estimated using simplifying
assumptions; friction coefficients of sliding pairings and thus their temperature rise and service life are functions of load, speed, temperature
and lubrication conditions; critical speeds and buckling lengths depend
on the rigidity and mass of the clamping and the machine frame etc.

Drive sizing
Required drive torque
Required drive torque of a worm gear
screw jack
The required drive torque of a worm gear screw jack is governed by
the axial load acting on the jack screw, the transmission ratio and the
efficiency. It should be noted that the breakaway torque may be
considerably higher than the torque required for continuous running.
This applies in particular to worm gear screw jacks with low efficiency
after a long standstill period. The acceleration torque should be checked
if necessary in cases with large spindle pitches and very short start-up
times.

It represents an average value which may vary to a greater or
lesser extent, depending on the running-in state, lubricant and
temperature. For values, see table.
Required drive torque for a worm gear
screw jack system
The required drive torque for a worm gear screw jack system is governed by the drive torque values for the individual jacks with allowance
for the static and dynamic frictional losses in transmission components
(coupling, universal joint shafts, pillow blocks, angle gear boxes, etc.).
It is useful to draw a diagram illustrating the flow of forces.
MT SHG1is the required drive torque for the worm gear screw jack SHG
1. It should be noted that the start-up torque (breakaway torque
and possibly acceleration torque) may be considerably higher
than the torque required for continuous running. This applies in
particular to worm gear screw jacks with low efficiency after a
long standstill period.
ηv1(V1) includes the static and dynamic frictional losses in the
pedestal bearings and couplings.

is the efficiency of connecting shaft V2.
ηv= 0.75...0.95 depending on the length of the shaft and number

If the worm gear screw jack jams as a result of the spindle coming into
contact with an obstacle, the toothing can still absorb the following
maximum torque values MT at the drive shaft.
In the case of screw jacks connected in series, the screw jack closest to
the drive can absorb this torque at its drive shaft.

Acceleration values
Three-phase asynchronous motor, 4-pole:
n Approx. 0.5 m/s2 (when switched on directly).
Servo motor:
nMax. 5 m/s2 (limited by max. drive torque).
When using screw jacks in conjunction with servo motors, note that:
n Greater masses are moved compared with linear axes.
nPredominantly constant speeds with different speeds of rotation are
used.
nUse is often in the area of the adjustment/positioning of equipment.
nPositions are travelled to with relatively short duty cycles and high
acceleration values are therefore less frequently called for.
nHigh acceleration values have only a negligible effect on the overall
stroke time, because of the low stroke speeds.
Forces and torque values acting on the
drive shaft
If worm gear screw jacks are not driven free of lateral forces by means
of a coupling connected to the motor shaft, but are instead driven by
chains or belts, care must be taken to ensure that the radial force acting
on the drive shaft does not exceed the limit values (see below).
In the worst case due to deflection caused by the radial force FR the
worm shaft will lift off of the worm gear wheel. This must be avoided,
since it impairs the engagement between worm shaft and worm gear
wheel and leads to higher wear.
Selection of drive motor
A suitable drive motor can be selected if the required drive torque and
drive speed are known. After selecting a drive motor, check that it will
not overload any of the worm gear screw jacks or transmission components. This risk may occur, in particular, in installations with several
screw jacks if they are loaded unevenly. It will generally be necessary to
install limit switches or torque-limiting couplings to protect the installation against impacting against end positions and obstacles.
Forces and torque values on the motor
shaft
Toothed-belt or chain drives may exert considerable radial forces on the
motor shaft if a very small sprocket is used. Please consult the motor
manufacturer in cases of doubt.
Selection of a bevel gearbox
Selection of a bevel gearbox is governed by the following factors:
n Drive torque
n Drive speed (see dimensional tables)
n Duty cycle and drive power
nForces and torques acting on the ends of the shaft
(please consult us in cases of doubt).
Required drive speed
The required drive speed is governed by the desired stroke speed, the
transmission ratio of the screw jack and the transmission ratio of the
other transmission components. A particular stroke speed can normally
be achieved in several ways. Correct selection depends on the following
criteria:
n Favourable efficiency.
nMinimum load on transmission components in order to achieve compact, low-cost design.
nAvoiding critical speeds for screw jacks and connecting shafts.
Screw jack nut torques
The nut torque (M) of the screw jack is the torque that the screw jack
exerts on the mounting plate (all N versions except V), or the torque
that the screw applies to the travelling nut (R Version). It is not to be
confused with the drive torque (MT) of the screw jack gears on the
worm shaft.
M [Nm] = Feff [kN] · fM (applicable in the areas of moderate and high
loads)
Mis the screw jack nut torque [Nm] for the “Lift under Load”
movement.
Feff is the actual supported axial force [kN].
fMis a conversion factor that accounts for spindle geometry and
friction. The value is applicable under normal lubrication conditions. The higher value applies to dry friction and static friction. In
the case of ball screw drives, fM is practically constant.

Universal joint shaft
ZR
The ZR universal joint shaft is particularly torsionally flexible and serves
to bridge large shaft distances at rotary speeds of up to 1500 rpm.
Thanks to the double arrangement of the toothed rings, large radial
displacements are possible with good damping characteristics.
The ZR universal joint shaft can be mounted radially without shifting the
gearbox or the motor.

They are supplied as a length of tube (dimension L to be specified by
customer) fitted with coupling assemblies at both ends. Pedestal bearings are generally not required, except for very long connections.
For optimum alignment of the screw jacks, we recommend the
use of universal joint shafts with clamping sets
Torsionally rigid universal joint shafts are used to connect several worm
gear screw jacks. The shafts attenuate noise, vibrations and impacts
and compensate for axial, radial and angular errors. They offer exceptional torsional rigidity, high temperature and oil resistance and are
particularly suitable where long lengths and/or high speeds are required.
Elastic universal joint shafts are maintenance-free; the central section
can be removed radially (to the side) without axial displacement of the
connected units.

Bevel gearboxes
Selection criteria
NEFF bevel gearboxes have strong grey cast iron housings, hardened
bevel gears lapped in pairs with spiral toothing and adequately dimensioned roller bearings. Spiral bevel gears offer the decisive advantage of
very favourable engagement ratios (high degree of overlap).
Consequently they are predestined for use under high stresses, coupled with optimum smooth running characteristics and high transmission accuracy.
The arc-shaped teeth are more resistant to bending than straight or
diagonal teeth. A further advantage is the relative insensitivity to elastic
deformation of gear wheels, shafts and bearings.
The gears can therefore also transmit extreme shock loads.
Three standard designs are available. 22 further variations are possible
as auxiliary drives. The gearboxes can be used in all installation positions and provided with various mounting holes. Cover and flanges are
generally provided with mounting holes.
Transmission ratios
The following standard transmission ratios are available: 1:1, 1.5:1, 2:1,
3:1, 4:1, 5:1 and 6:1.
All transmission ratios are mathematically precise. The gearboxes can
be used as step-up and step-down gearboxes.
Custom transmission ratios are available. Please enquire.
Efficiency
The efficiency of the NEFF bevel gearboxes is 94 – 98 %, depending on
speed, installation position, sealing and type of lubricant. The efficiencies refer to the rated performances of the gearboxes.
In certain installation positions the bevel gears are fully immersed into
the lubricant. In case of larger gearboxes and high peripheral speeds of
the gear wheels, the churning losses cannot be neglected and NEFF
must be consulted.
Note that the start-up efficiency is always smaller than the operational
efficiency. The resultant increased breakaway torque must be considered in the design of the drive performance.
Low-backlash version
As standard the bevel gearboxes have a circumferential backlash of 10 to
30 angular minutes, depending on the size of the transmission and the
transmission ratio.
However, all NEFF bevel gearboxes can be supplied in a low-backlash
version.
The circumferential backlash at the slow-running shaft is measured with
the drive shaft blocked on a lever arm of 100 mm with a measuring force
of 3% of the nominal torque and given as the torsion angle.
The following values are adjustable with normal gear wheel sets:
Version S1: i = 1:1 to 2:1 < 6 angular minutes
Version S2: i = 3:1 to 6:1 <10 angular minutes
Tighter values require select, HPGS-toothed or polished gear wheel sets
- please enquire.
Lubrication
NEFF bevel gearboxes are delivered with an oil filling and are maintenance-free under normal operating conditions. In case of extreme
requirements or increased service life requirements, we recommend an
oil change approx. every 15.000 hours of operation.
NEFF strives to select the best lubricant for each application and in this
way to optimise the service life of the gearboxes.
Decisive for the choice of lubricants are the peripheral speed of the
bevel gears, the power to be transmitted and the operating conditions.
An approximate guiding value for the type of lubrication used can be
taken from the two selection diagrams and the lubricant table.
The correct type of lubrication can be selected on the basis of two selection diagrams and a lubricant table. The selection diagrams take into
account the catalogue nominal torque and the mode of operation of the
gearbox with 100% duty cycle or 30% / hr intermittent operation.
After the selection of the mode of operation and taking into consideration the operating conditions, the type of lubricant is defined with the
speed of the slow-running transmission shaft. The type of lubrication,
the necessity of gearbox ventilation and the gearbox oil can be taken
from the lubricant table shown below.
The actual type of lubrication is defined by us for the specific application
and may deviate from the table values!
There is a choice of modern synthetic high-performance lubricants.
Proven lubricants with NSF-H1 approval (USDA-H1) can be selected for
the use of gearboxes in the pharmaceutical or food industries.
NEFF gearboxes are provided with lifetime lubrication. Lubricant quantities are defined internally within the company for the installation position. Of course, biologically degradable oils or lubricants for extreme
operating conditions can also be supplied. Please consult NEFF.
Due to the small convection surface the temperature of the gearbox
can exceed 50 °C even under normal operating conditions.
If the gearbox exceeds this temperature in use, the ventilation filter
provided must be installed in order to avoid overpressure in the gearbox
and thus a leak in the gearbox.
The supply of fresh air must be ensured. Please consult us in cases of
extreme environmental conditions (dust, moisture, etc.).
The ventilation bore can be dispensed with in case of intermittent
operation or other operating conditions where the gearbox temperature
is not expected to exceed 50 °C.
Preferable direction of rotation
In principle NEFF bevel gearboxes can be driven in both directions of
rotation. Together with the direction of rotation, the spiral direction of a
gear wheel set determines the internal load ratios of the gearbox.
If one selects the direction of rotation of the small gear contrary to its
spiral direction (viewed from the shaft end face to the centre of the
gearbox), then the axial force acts outwards. As a result the gear wheel
set is pressed apart and causes a lowering of the noise level by 1 - 2
dBA.
NEFF manufactures the pinion as a left-hand spiral; the preferable direction of rotation is thus clockwise.

Position of the ventilation filter
With the lubrication types B1 and B2 the gearbox is supplied with
a ventilation filter. Please refer to the table below for the possible
positions of the filter. The side of the gearbox on which the filter will be
mounted is to be specified in the ordering designation.
e.g.: E4 = ventilation on side 4. If nothing is specified in the order, the
position of the ventilation filter is determined by NEFF.

Installation
and maintenance
Installation of worm gear
screw jack systems
Maintenance of
worm gear screw jacks
Direction of rotation
Before starting installation work, the direction of rotation of all worm
gear screw jacks, bevel gear boxes and the drive motor must be
checked with regard to the feed direction of each individual worm gear
screw jack.
Safety
All mounting bolts must be retightened after a short period of operation. Under extreme operating conditions, the wear on the screw nut
(worm gear) must be checked at shorter intervals, depending on the
duty cycle, by inspecting the backlash in the thread.
The screw nut (worm gear) must be replaced if the axial backlash with a
single-start thread is more than one-quarter of the thread pitch.
Alignment errors
All components must be carefully aligned during installation. Alignment errors and stresses increase power consumption and lead to
overheating and premature wear. Before a drive unit is attached, each
worm gear screw jack should be turned through its entire length by
hand without load. Variations in the amount of force required and/or
axial marks on the outside diameter of the spindle indicate alignment
errors between the worm gear screw jack and its additional guides. In
this case, the relevant mounting bolts must be loosened and the worm
gear screw jack turned through by hand again. If the amount of force
required is now constant throughout, the appropriate components must
be aligned. If not, the alignment error must be localized by loosening
additional mounting bolts.
Test run
The direction of rotation of the complete system and correct operation
of the limit switches must be checked again before attaching the drive
motor. In the case of version N (translating screw jack), check that the
spindle is lubricated with grease from the interior of the gear box and
relubricate if necessary. In the case of version R (rotating screw jack),
the screw jack should be coated with suitable grease to provide lubrication for lifting operation. The first test runs can then be carried out
without load. A maximum operating time of 30 % cannot be exceeded
at trial runs under weight for worm gear screw jacks with trapezoidal
spindles.
Operation
The loads, speeds of rotation and operating conditions specified for
the worm gear screw jacks and transmission components must not be
exceeded, even briefly. Failure to observe this condition will invalidate
all claims under guarantee.
Guiding values for the mounting of bearing
covers
Lubrication
The worm gear screw jacks are lubricated by the manufacturer and are
ready for operation on delivery.
The versions N/V must be lubricated via their grease nipples with one
of the greases specified below at intervals of 50 – 100 operating hours,
depending on the grease seepage and in cases of high duty cycles.
The spindle should be cleaned and greased at the same time.
We recommend that the gearbox be cleaned to remove old grease
and refilled with fresh grease after approx. 1500 operating hours or 36
months.
The worm gear screw jacks can be dismantled relatively easily:
n Unscrew the two threaded pins securing the bearing cover.
n Unscrew the spindle and remove the spindle protection if necessary.
n Unscrew the bearing cover with the aid of a face spanner.
Proceed as follows to refit the bearing cover: fit the bearing cover firmly
(using approx. ten times the force shown in the table of “Guiding values
for fitting the bearing cover”).
Then release it and refit it with the guiding value from the table, at the
same time checking the axial backlash and smooth running.
