WorKing teMPerAtureS

Fenner Ultra PLUS and CRE PLUS wedge belts perform satisfactorily within the temperature range -40 to +70°C

Quattro PLUS temperature range -40 to +80°C

Ultra PLUS 150 temperature range -40° to +80°C

Metric designations are ‘pitch’ lengths in mm.

Imperial belt designation denotes approximate

‘effective’ length in tenths of an inch in accordance with RMA standards.

Note: The ISO 4184 standard now refers to ‘datum’ lengths, which are essentially the same as ‘pitch’ lengths.

For similar cross sections, other designations include

SPZ, Alpha, 3V & 9N

SPB, Beta, 5V & 15N

8V, Delta, & 25N

SPZ, SPA, SPB & SPC belt designations shown in heavier type identify standard sizes in ISO 4184. Belt lengths in italic type are available but not ex stock in all locations.

Consult your Authorised Distributor for non-listed belt lengths.

Wedge Belt Drive Selection

Friction Belt DriveS

Selection

(a) Service Factor

Calculate Speed Ratio by dividing the rev/min of the faster shaft by the rev/min of the slower shaft.

n.B. The powers listed in the columns headed by the motor speeds in the Drive Tables

(pages 40 to 51) give the power per belt including Speed Ratio Increment, step (j), for

Ultra PLUS wedge belts. These powers require correcting for belt length and arc of contact correction factor (g) and should be used in conjunction with the appropriate

Service Factor.

(b) Service Factor

From Table 3 (page 39), select the Service Factor which is applicable to the drive. If the drive is speed increasing, an additional factor may be required – refer to top of Table 3.

(j) Speed ratio Power increment

From the power rating tables (pages 52 to 59) note the additional power per belt for the Speed

Ratio being used.

This value is the same for all types of belt of a given section.

(c) Design Power

Multiply the normal running power or prime mover power by the Service Factor. This gives the Design Power which is used as the basis for selecting the drive.

(k) corrected Power per Belt

Add the Speed Ratio Power increment (j) to the Basic Power per Belt (h) and multiply by the

Correction Factor from step (g).

(d) Belt Section & type

Refer to Table 2 (opposite) and trace to the right along the horizontal axis to the rev/min of the faster shaft. Trace upwards along the vertical axis to the Design Power. Choose the belt section and type represented by the area in which the point of intersection falls.

(l) number of Belts required

Divide the Design Power from step (c) by the Corrected Power per Belt (k). The result gives the number of belts required. If the answer contains a fraction use the next whole number.

(e) Minimum Pulley Diameter

Refer to Table 1 (below) and select the minimum recommended pulley, using the Design

Power from step (c) and the faster shaft speed. This is a guide to the minimum pulley pitch diameter capable of transmitting the design power at the given speed,without generating excessive bearing loads.

(m) Bore sizes

Check that the pulleys will fit shafts by referring to the pulley dimension tables (pages 62 to 69).

tABle 2

(f) Pulley Pitch Diameters

Refer to the drive selection tables on pages 40 to 51 and for the belt section chosen read down the speed ratio column to the value nearest the calculated speed ratio. Use the Minimum Pulley Diameter from step (e) as a guide to the small pulley selection.

only

The drive tables list ISO belt lengths.

Along the same line as the chosen Speed Ratio read across the table to find a suitable

Centre Distance. The required Belt Length is given at the head of the column.

Note the Correction Factor by following the colour band in which the chosen centre distance falls, to the top of the table.

If the Centre Distance is not specified consider a drive with a centre distance approximately equal to the sum of the pulley pitch diameters.

When non-standard pulleys or belts are used the Centre Distance and Belt Length can be calculated using the formulae given on page iii of the technical information section.

Interpolate from the tables for the Correction Factor.

For CRE Plus belts refer to page 56 for power ratings.

Note that Fenner pulleys are designed for belt speeds up to 40 m/s. If using non-Fenner pulleys seek manufacturer's approval at high speeds.

Wedge Belt Drive Selection

Section : 3 eXAMPle

Design a wedge belt drive from a 50 kW 6 cylinder diesel engine which runs at

1050 rev/min to a reciprocating compressor running at 660 rev/min. The centre distance is to be approximately 1600 mm and the duty is 24 hours/day. The engine shaft is 70 mm diameter and the compressor shaft 80 mm diameter.

(a) Speed ratio

Speed ratio = 1050 = 1.59:1

660

(b) Service Factor

From Table 3 the service factor is 1.4.

(c) Design Power

= 50 x 1.4 = 70 kW

(d) Belt Section

By referring to Table 2 (opposite) the intersection of design power and the speed of the faster shaft indicates SPB or QXPB section.

(e) Minimum Pulley

From Table 1 (page 38) the minimum recommended pulley is approximately 250 mm.

(f) Pulley Pitch Diameters

By referring to the centre distance tables relating to SPB section belts on page 47 the selection is a driving pulley of 315 mm pitch diameter and a driven pulley of

500 mm pitch diameter.

(g) Belt length, centre Distance and correction Factor

Reading across the table, the nearest centre distance to the 1600 mm required is 1607 mm. The belt length at the head of the column is 4500. By following the colour shading to the top of the table, a correction factor of 1.05 is noted.

(h) Basic Power per Belt

From the power rating table (pages 52 & 61) by interpolation the rated power/belt for a 315 mm pitch diameter pulley at 1050 rev/min is 18.94kW for Ultra PLUS SPB

(22.37 for Quattro PLUS QXPB)

(j) Speed ratio Power increment

The power increment (by interpolation) for a speed ratio of 1.59 at 1050 rev/min is

0.77 kW. (pages 58)

(k) corrected Power per Belt

= (18.94 + 0.77) x 1.05

= 20.7 kW per belt. (24.3 for QXPB)

(l) number of Belts required

= 70 = 3.38

20.7 or

= 70 = 2.88 i.e

use 4 SPB Ultra PLUS wedge belts.

i.e

use 3 QXPB Quattro PLUS belts.

24.3

(m) Bore Sizes

From pulley dimension tables, a 315mm x 4 SPB has a bush size 3525 with 100 mm max. bore (315 mm x 3 SPB has a bush size 3020 with 75 mm max. bore).

Either will fit the 70 mm dia. engine shaft.

500 mm x 3 or 4 SPB pulleys, both of which have a bush size 3525, will fit the 80 mm dia. compressor shaft.

Type 6NR pulleys are made to catalogue dimensions, but modern manufacturing techniques result in there being no recess behind the Taper Lock bush, the J dimension is then approximately equal to the small diameter of the Taper Lock bush.

PowerTwist PLUS

®

Belting

Friction Belt DriveS

PowerTwist PLUS belting incorporates the most up-to-date materials available, giving it unique qualities of resistance to many of the adverse working conditions that belts are subject to, and properties that were deficient in earlier designs of link belts. These link belts are complementary to the range of

Fenner wedge and Vee Belts and are extensively used in industrial, marine, agricultural and heating & ventilation applications.

Advantages of Powertwist PluS link Belts

Adjustable to any length, adaptable to any drive

Fit the belts to the drive, not the drive to the belts.

Drive elements can be located most effectively and belts installed without removing bearings.

no Slippage

Quick, easy length adjustment minimises belt creep to guarantee full speed and full productivity of machines.

Minimum inventory

Four boxes of link belting can replace hundreds of fixed length, endless V-Belts.

Boxes can be stored easily, providing simplified visual control of inventory.

vibration

Fenner link belts are manufactured to extemely close tolerances.

The design of the belt significantly reduces transmissible vibrations in some applications.

long lasting construction

The extreme flexibility of these belts greatly reduces belt stress, heat build up and fatigue. The construction of the belts is designed to dissipate heat.

Maximum Power Delivery

On multiple belt drives it is easy to maintain correct tension on all belts. Each belt carries its required load, for maximum power delivery and longest life.

temperature

Power Twist Plus will operate in temperatures from - 40 to 110

O

C.

Water, chemical & oil resistance

This belt will not degrade if immersed in water or if in contact with oil, grease, agricultural chemicals and common solvents.

economical lengths

PowerTwist belting is also available in economical lengths.

Boxed in 10 metre lengths, ideal for display or mobile maintenance engineers.

Special types

Double v Section

For use on serpentine drives with both sides of the belt engaging in V pulley grooves.

AA; BB & CC sections.

ground round

Designed specifically to replace round profile rubber or leather belts on "rope" drives.

8mm, 9.5mm, 12.5mm, 14mm & 19mm diameters.

High grip, or PTFE top layer coatings available for conveying applications.

Belting

Section : 3

PowerTwist Plus link V-Belts are manufactured from an exclusive, high strength urethane/polyester composite. This makes PowerTwist Plus an incredibly strong, yet flexible belt that will take on the roughest of working conditions.

PowerTwist Plus V-Belt's unique cross-lock design gives a raw edge cog construction which provides excellent durability and performance, delivering higher power ratings than almost any other link type V-Belts on the market.

When the tension is applied to the belt, the cross-link design locks tightly thus producing the lowest stretch of any link V-Belt.

PowerTwist Plus V-Belts save time on installation because no special tools are required, all that is needed is a quick twist both to couple or uncouple the belt and this is easily achieved in seconds.

Available from stock in Z, A, B and C sections, for use in standard dual groove pulleys. See pages 62-69.

Bi-loc Pulleys

The Fenner Bi-Loc system employs lightweight cast iron pulleys with 'Quadruple Duty' Grooves for A/SPA and B/SPB section belts. Twin-tapered steel bushes with metric and Imperial bores are used to mount single, double or different diameter pulleys on one shaft. A shrunk-on fit is achieved without keys or grub screws. Only a spanner is needed for fitting and removal.

„

Mount single, double or different diameter pulleys on one bush.

„

Use retainer and screws for single pulley assembly.

„ Use bolts for double groove pulley assembly.

Fenner Wedge and Vee-Belt Tensioning Instructions

Friction Belt DriveS

"one-Shot" tensioning

Fenner belts are Precision Built to ensure inherent length stability and matching during storage and on the drive.

Over many years, the principle of "one-shot" tensioning has been verified by successful drives the world over.

„ Install the belts to be a snug fit around the pulleys.

„ Spin the pulleys 3-4 revolutions to bed belts into the pulley grooves.

(Note: if done manually, beware of finger entrapment between belts and pulleys)

„

Tension the belts to the 1.25x setting forces from the table.

„

Run the drive under load for 15-20 minutes.

„ Stop the drive, check tension & reset to the basic value (standard V and wedge belts) if necessary.

CRE PLUS & Quattro PLUS belts should be reset to the 1.25x value.

With a drive that is properly designed for the application there should be no need for further attention during the life of the belts.

For short centre distance drives where the deflection of the belt is too small to measure accurately it is recommended that both deflection and setting force be doubled.

Method of belt tensioning using Fenner Belt tension indicator

„

Calculate the deflection in mm on a basis of 16mm per metre of centre distance. Centre distance (metres) x 16 = deflection (mm).

„

Set the lower marker ring at the deflection distance required in mm on the lower scale.

„

Set the upper marker ring against the bottom edge of the top tube.

„

Place the belt tension indicator on top of the belt at the centre of span, and apply a force at right angles to the belt, deflecting it to the point where the lower marker ring is level with the top of an adjacent belt.

„ Read off the setting force value indicated by the top edge of the upper marker ring.

„ Compare this force to the kgf value shown in the table.

„ If a Fenner Belt Tension Indicator is not available, a spring balance and rule will suffice.

noteS:

For single belt drives a straight edge should be placed across the two pulleys to act as a datum for measuring the amount of deflection.

If the measured force falls within the values given, the drive should be satisfactory. A measured force below the basic value indicates under-tensioning.

A new drive should be tensioned to the 1.25x value to allow for the normal drop in tension during the running-in period.

After the drive has been running for 15–20 minutes, under load the tension should be checked and readjusted, if necessary.

Often caused by incorrect tensioning, particularly on long centre drives. If a slightly higher (or lower) tension does not cure the problem there may be a critical vibration frequency in the system which requires re-design or use of banded belts. Consult your local Authorised Distributor Technical Services.

Pulleys

Pulley groove wear can cause rapid belt failure.

Check grooves for wear with a Fenner groove gauge.

Friction Belt DriveS

Installation and Operation of Wedge and Vee-Belt Drives

Section : 3

Although comparatively old in principle today's belt drive is an extremely efficient method of transmitting power between prime mover and machinery.

It owes its present high performance standards to many years of research and development by engineers and technologists, leading to significant refinements in materials and processes.

To derive maximum benefit from such advances it is important that the simple installation and operation procedures set out here are closely followed. Making these routines standard practice will ensure optimum performance and long, trouble-free life from Fenner belt drives.

installation

„

PulleYS

Before assembling the drive, check the pulley grooves are free from scores or sharp edges, and all dimensions conform to the relevant standard.

Drive installation is straightforward with Taper

Lock – but follow all steps on the installation leaflet provided with every Taper Lock bush.

„

AlignMent

Good alignment of pulleys is important to avoid belt flank wear. The diagrams opposite show some of the common alignment faults.

Pulley misalignment should not exceed 1/2° angular and 10mm / metre drive centre distance, axial.

A laser alignment device is available, which facilitates quick, easy and accurate pulley alignment - consult your local Authorised

Distributor.

„

Belt inStAllAtion

When the pulleys have been correctly positioned on the shafts, the belts can be installed to complete the drive.

The drive centre distance should be reduced prior to the installation of the belts so that they may be fitted without the use of force. Under no circumstances must belts be prised into the grooves. Belts and pulley grooves can easily be damaged by using sharp tools to stretch the belts over the pulley rim.

The installation allowance given in the table opposite is the minimum recommended reduction in centre distance for the various belt sections and lengths to allow for correct fitting.

The take-up allowance given in the same table should be added on to the calculated centre distance to allow for belt stretch/bedding in.

„

guArDS

Where guards are necessary it is desirable to use mesh materials to permit adequate ventilation.

Guards should be generously sized to allow for incidental belt flap.

„

tenSioning PulleYS

If tensioning (jockey) pulleys are to be used on wedge belt drives, they must be grooved pulleys working on the inside of the drive, preferably on the slack side.

The pulley should be positioned as close as possible to the large pulley. Flat tensioning pulleys, bearing on the outside of the drive are permissible only with V and not with wedge belts. They should be positioned within one third of the centre distance from the small pulley.

The tensioning pulley must have at least the same diameter as the small pulley of the drive.

Tensioning pulley movemement must allow for passing the belts over the outside diameter of one of the drive pulleys on installation, and should also allow for belt stretch/bedding in.

PowerTwist PLUS Installation and Tensioning

1. How to Measure

Pitch Length

Correct way to measure:

PowerTwist Plus – end of tab to first empty holes (right to left, above)

2. Assembly - Powertwist PluS

Friction Belt DriveS

Determine the required pitch length of the belt. Measure PowerTwist Plus from the second empty hole on the last link to the end tab. Subtract one link in every 24 for

Z, A, B sections, one link in every 20 for C section. For multiple belt drives, count the number of links in the initial belt and make additional belts the same number of links. Lay the original belt on a table and lay the additional belts side by side to ensure the correct length and matched sets.

Always work with the belt inside out, tabs pointing outward

Place end tab through two links at once.

Flex belt further and insert second tab through end link by twisting tab with thumb.

Ensure tab returns to position across belt.

Reverse belt so tabs run inside.

3. installation

Make Powertwist Plus belts to the correct pitch length and then install them as you would an endless belt.

1. Move motor to reduce centre distance.

2. Place all belts in correct position.

Where it is necessary to thread belts through confined spaces, or around shafts without moving bearings, it is possible to make the belts "in site". Some reduction in pulley centre distance is still necessary for ease of assembly.

3. Move motor back into position, applying correct tension.

4. Secure motor tightly.

Method of Belt tensioning using Fenner Belt tension indicator

1. Calculate the deflection distance in mm on a basis of 16mm per metre of span.

Centre Distance (m) x 16 = Deflection (mm)

2. Set the lower marker ring at the deflection distance required in mm on the lower scale.

3. Set the upper marker ring against the bottom edge of the top tube.

4. Place the belt tension indicator on top of the belt at the centre of span, and apply a force at right angles to the belt deflecting it to the point where the lower marker ring is level with the top of an adjacent belt*.

5. Read off the force value indicated by the top edge of the upper marker ring.

6. Compare this force to the kgf value shown in the table opposite.

7. If a Fenner Belt Tension Indicator is not available, a spring balance and rule will suffice.

cAution

When properly installed, initial tension may appear excessive.

Tension drops to normal when drive begins to run.

4. retensioning

It is important to retension all drives after an initial run-in period. On fixed centre drives, it may be necessary to remove a link from each belt for proper retensioning.

If the measured force falls within the values given, the drive should be satisfactory.

A measured force below the lower value indicates under-tensioning.

A new drive should be tensioned to the higher value to allow for the normal drop in tension during the running-in period.

After the drive has been running for 30 minutes, the tension should be checked and re-adjusted to the higher value, if necessary.

5. Disassembly - Powertwist PluS

Turn belt inside out with tabs pointing outwards. Bend back as far as possible; hold with one hand. Twist one tab 90º parallel with slot.

78

Pull end of link over tab.

Rotate belt end with tab at 90º to line of belt.

Pull belt end through two links.

PolyDrive PLUS Belt Selection

Friction Belt DriveS

Necessary drive data: Driving/driven shaft speeds (rev/min), absorbed drive power and/ or motor power (kW), type of prime mover (inc. electric motor starting arrangements) and driven machine, machine shaft diameters (mm or ins.), required drive centre distance (mm), any other dimensional constraints.

(a) Service Factor

Select the service factor applicable to the drive from table 1 below. For a speed increasing drive multiply the basic service factor by the special factor in the top left box to achieve the full service factor.

(b) Design Power

Multiply the normal running (absorbed) power of the drive, or if not known, the motor power, by the service factor (a), to give the design power which is used as the basis for drive selection. This power should be calculated in kW.

(c) ribbed Belt Section

Refer to table 2, page 81 and find the point of intersection of the faster drive shaft speed in rev/min, and the design power

(b). This point will indicate required belt section and approximate small pulley diameters/ rib numbers.

NOTE: PK section ribbed belts are normally used for automotive applications. For general industrial applications PJ, PL or PM section belts should be selected.

(d) Speed ratio

Divide rev/min of faster shaft by that of the slower shaft to give required speed ratio.

(e) Minimum Small Pulley Diameter

Refer to table 5, page 81 to find the minimum recommended small pulley diameter, using design power (b) and the faster shaft speed.

(f) Pulley effective* Diameters

Refer to table 6, page 82 to select pulley effective diameters giving close to the required speed ratio (d), using (e) as a guide to small pulley diameter.

Calculate the exact speed ratio and check acceptability

* Note: All pulley designations show effective (outside) diameters. Exact speed ratios are calculated using pitch diameters,– see under table 6, page 82.

SPeeD increASe rAtio

For speed increasing drives of:

Speed ratio 1.00 – 1.24 multiply service factor by 1.00

Speed ratio 1.25 – 1.74 multiply service factor by 1.05

Speed ratio 1.75 – 2.49 multiply service factor by 1.11

Speed ratio 2.50 – 3.49 multiply service factor by 1.18

Speed ratio 3.50 and over multiply service factor by 1.25

tYPeS oF Driven MAcHine

(g) Belt length and centre Distance

Use the formulae below to establish which standard belt length (listed page 79) gives closest to the required drive centre distance.

(h) combined correction Factor

Refer to tables 3 & 4, page 81 to find power correction factors for belt length and for the arc of contact for the small pulley (the latter calculated using pulley diameters D & d, and centre distance C - all in mm).

Multiply these two factors together to give the combined correction factor.

(j) Basic/Additional Power per rib

The main power rating tables on pages 82 & 83 show basic power per belt rib, in kW, at the intersection of faster shaft speed (LH column, in rev/min) with pulley diameter (across top, in mm). Additional power per rib due to speed ratio is shown in the smaller RH table. Values for shaft speeds not listed can be derived by interpolation.

(k) corrected Power per rib

Add the speed ratio increment to the basic power per rib (j) and multiply the the resultant kW value by the combined correction factor (h) to give the full power per rib.

(l) number of ribs required

Divide design power (b) by the full power per rib (k) to give the number of belt ribs required. Round up to an even number and check whether standard pulleys are available.

(m) Pulleys

When pulley specification is established, consult your local Authorised Distributor to check availability of pulleys with Taper Lock bush shaft fixing, and associated bore size capacity.

SHAFt AlignMent

The maximum axial misalignment allowed is 3 mm per metre centre distance, to a maximum of 15 mm.

Make sure that angular misalignment is kept within 2 o not exceed 1 o .

. With flat pulleys, acting as idlers for power take-off, do

A laser alignment device is available, which facilitates quick, easy and accurate pulley alignment - consult your local Authorised Distributor.

tenSioning tHe Belt

Ribbed belts must be tensioned correctly and with great care. Under or over-tensioning can cause functional problems and lead to premature belt failure. We recommend the elongation method, which is simple and requires no special equipment, in most cases.

(For narrow belts - less than 40 mm wide - it is possible to use the Fenner Belt Tension Indicator).

1. Fit the belt on the pulleys with no tension,

2. Draw two lines perpendicularly across the belt back approx 80% of the belt span apart (or one metre apart for very long spans),

3. Increase the distance between the two lines by 0.5 to 0.75% i.e. by 5 to 7.5 mm for an initial spacing of

1000 mm.

4. Run the drive under load for about 10 minutes,

5. Check the tension of the belt (i.e. the spacing between the two lines) and readjust if necessary.

generAl

Pulleys should be mounted as close as possible to bearings, to reduce overhung load.

Pulley grooves should be in good condition, clean, and free from sharp edges.

Ensure that drive machinery is securely fastened after belt installation or adjustments.

Guards should be generously sized and well ventilated.

Friction Belt DriveS

Accessories

the Fenner S.c.i.e.n.c.e. explained

Did you know that

70%

of friction drives are incorrectly installed?

that figure is quite astounding particularly when you consider how many applications are dependant on the efficiency and reliability of friction belt drives.

But don't panic, with a just a few simple steps and the assistance of your

Local Authorised Fenner Distributor, we can ensure that your belt drives (and chain drives) achieve their optimum efficiency, full operating life and provide reliable performance.

With Fenner it's all about the S.c.i.e.n.c.e. - Select correctly, install

effectively, never compromise efficiency, if you adhere to these simple rules you can be confident that your drive selection will perform.

Select correctly

A correctly selected drive for your application will ensure the drive uses the fewest number of belts or the absolute minimum of belt width, which in turn.

„ Reduces loading on the machines bearings increasing the life cycle of the machine, reducing downtime and the risk of mechanical failure

„

Reduces the noise levels keeping noise pollution to a minimum at high speeds

„

Reduces the amount of raw materials and resources used cutting down on waste an subsequent pollution

install effectively

Correct installation - once you have carefully selected your belt drive components - is paramount to the longevity and efficiency of your belt drive, by following the correct installation procedures to the letter and by using the right tools for the job, such as the Fenner laser alignment and tensioning devices, we can;

„ Reduce the vibration to which the machine bearings are subjected, prolonging machine life, minimising downtime and reducing the risk of severe damage to the driven machine

„

Ensure the drive operates and delivers its maximum rated power at its premium efficiency, reducing both waste and pollution

„ Supply a drive which gives the maximum drive life available on the market using the minimum of resource to maintain

never compromise efficiency

By including belt drives as an integral part of a planned maintenance schedule you can:

„ Ensure the process up-time is at an absolute maximum giving the ultimate production output maximising operational efficiency

„

Prolong the life of the drive and negate the need to waste costly resources on breakdowns and drive problems

„

Extend drive, machine and bearing life to the maximum, using less raw materials and guarantee sustainability.

remember your drive stands or falls by the accuracy of its installation, so take the time to get this right and you will reap the rewards. use the S.c.i.e.n.c.e
