TORQUE LIMITERS - CLUTCHES: introduction
ComInTec torque limiters are mechanical components necessary to fit along the kinematic chain and are preferred to electronic safety
devices because of a better response time, improved reliability, excellent configuration flexibility, easy fitting and adjustment, use at high
speeds in hard environments in the presence of inertias and important masses. In fact the electronic systems, which normally act up to the
transmission, present: delayed reaction time, many factors as a source of error, configuration and management complexity.
The fitting of the mechanical torque limiters along the kinematic chain is therefore necessary for a reliable and complete protection, in order
to improve the level of safety and the machine, according to the new EN ISO 13489-1 standards, reducing the average possible broken-down
and unproductive downtime.

FRICTION TORQUE LIMITER “DF”: additional information
VERSIONS ON REQUEST
…/CM: minimum torque version
Helical springs execution, for a higher torque range
and consequently, a finer adjustment on
calibration is possible
Stainless steel ring
…/EA: rust resistant
Rust resistant execution, with stainless steel
rings, galvanized for application in wet
environments.

…/MFR: reduced flange hub version
Reduced flange hub execution, to assemble
elements with reduced diameters. Available
with two or three bushes version.
…/MS: overload detection version
Our suggestion to increase the life of the friction
rings and to maintain the torque limiter
efficiency is (it is possible and advised) to stop
the machine immediately, on the first slip
caused by an overload. This is possible by using
one proximity inductive sensor, which registers
any speed anomaly, as indicated in the picture.

FRICTION TORQUE LIMITER “DF”: additional information
PLATE WHEELS
The driving part selected (plate wheels, pulleys, gears, and so on) to be incorporated into the friction torque limiter, must adhere to
predetermined characteristics (ex. the surface in contact to the friction rings with roughness Ra=0,8 : 1,6) to ensure good performance.
In the table below, there are standard plate wheels in ComInTec's production (supplied already grounded) which can be assembled on the
torque limiter; and the minimum chain passage “V” (see picture 3), necessary for the correct sizing of the plate wheel to avoid contact
between the chain and outside diameter of the limiter. It is possible to assemble various types of plate wheels, but the surfaces must be
machined, and the chain passage cannot be smaller than this value. Another aspect to take into consideration to ensure the dimension of the
assembly is correct, is the element thickness and its relevant bush “N” (see picture 1). We suggest to obtain a quote “N” equal to [ S + G + 1 ].
Comparing “N” value obtained, to the Nstd indicated on the table, which corresponds to the standard length of the bushes, you can have: “N”
< “Nstd” (picture 1 - ex.A) ® reduce the bush width to quote “N”.
“N” > “Nstd” (picture 2 - exB) ® machine the driving part at a diameter of "A+1" and a depth equal to “x” (N - Nstd).
Example “A” (see picture 1)
1.70 with plate wheel #7
G = 7 mm
S = 4 mm
N = S + G + 1 = 4 + 7 + 1 = 12
Nstd = 15
Reduce the bush width to 12 mm.
where:
p = pitch [in]
G = thickness of the ground element
Z
= teeth number
dp = pitch diameter
S
Example “B” (see picture 2)
1.70 with plate wheel #13
G = 13 mm
S = 4 mm
N = S + G + 1 = 4 + 13 + 1 = 18
Nstd = 15
Machine ø71 with depth (value “x”=18-15=3)
= thickness of the friction ring
Nstd = thickness of the standard bush
N = thickness of the calculated bush (S+G+1)
A = outside diameter of the torque limiter
V = inside diameter of the chain
x
= depth of the machining (N - Nstd)

VERSIONS
Force (N)
Torque (Nm)
Torque calibration (Nm)
This allows for a simpler and more linear calibration.
Moreover, during disengagement it creates an increase
in the torque, caused by the compression of springs,
which, on presence of a non-homogenous (but normal)
transmission, can be useful to avoid frequent
disengagements and machine stops.

…/P
Positive version (progressive spring)
…/N
Negative version (regressive spring)
It generates an immediate torque reduction, as soon as
there is a minor overload, with consequent
disengagement of the limiter and immediate stop of the
drive. This characteristic is very useful on sensitive
applications where even a slight increase of the loads
can cause damage to the machine or to the machine
product.

TORQUE REGULATION
…/P
Positive version (progressive spring)
As with the majority of ComInTec TORQUE LIMITERS, by
turning the adjuster nut clockwise the disengagement
torque increases. On the contrary turning it counterclockwise, you obtain a reduction of the torque.

DSS/F/SG negative version
Nut DSS/F/SG negative version
Adjustment of the Negative version is opposite to all
other units in our range. Unlike the traditional units, by
rotating the adjuster nut clockwise the disengagement
torque will reduce, and therefore to increase the torque
the nut must be rotated anti-clockwise. To assist the
operator in setting, there are clear markings on the nut
showing 75% of the max torque and +/- Min/Max
directions indicated.
Unless otherwise requested, these models are
supplied pre-calibrated at 75% of the maximum torque
value of the spring's chosen configuration.

CALIBRATION SYSTEM WITH "H" DIMENSION
The transmitted force of a torque limiter can be determined with one or more axial springs and different forces, depending on how they
are combined. Efficient controls on all components make it possible to realize tables for simple, easy and most of all, quick torque limiter
calibration, without any need of special equipment.
Search in the technical catalogues, in the table "torque calibration" the value that is closest to the required torque of the selected torque
limiter size and spring combination. Find the related value of "dimension H". Alter the spring pressure by adjusting the ring nut until you
reach "dimension H", the distance between nut ring and flange (see drawings). Finally, fix the nut ring by its locking mechanism.
With this calibration system you obtain:
Torque calibration without removing the torque limiter.
Quick torque calibration.
Avoid calculating and reading errors due to misinterpretation of drawings.
Simple variation or reset of the torque.

EXAMPLES OF DETERMINING, REGULATING AND CALIBRATING A TORQUE LIMITER
Electric motor:
Torque range
power = 7,5 kW
Rpm = 1450
f (safety factor) = 1,5
Use the following formula to get an idea of the intervention
torque:

Rpm
Find in the technical catalogue (in this case DF)
the required spring combination and the relative dimension
H for the selected torque limiter (in this case DSF 1.70),
to have the desired torque (in this case springset A1M1 –
dimension H 12,2 mm – torque 74Nm).
Please note: Due to the expansion coefficient and the
load loss of all springs in general, the "dimension H" can
vary slightly.
You can find all the calibration torque values by typing in
"dimension H" on our website "www.comintec.it".
