Assembly instructions

for

low backlash

torque limiters

For the TL 1 – TL 3 models, the fit tolerance between the shaft and hub must be
between 0.01 and 0.05 mm. Ensure that the coupling hub mounts smoothly on the
shaft prior to assembly. Lightly oil the shaft prior to assembly. Do not use oils or grease
with sliding additives (for example, MoS

). Any keyways in the shaft will not affect the

functioning of the clamp connection.

Model TL1 has an integrated

bearing

(1)

for the attached component (for

example, a pulley or sprocket wheel).
Do not exceed the

maximum radial

force (2)

, (see table). By centering

the load between the

dimension (S)

sufficient force is applied between the
two balls and no separate bearings
are required. Additional bearings are
required for offset mounting. This is rec-
ommended, for example, if the attached
component has a very small diameter or
a very large width. Ball bearings, needle
bearings or bushings can be used de-
pending on the installation situation.

WITTENSTEIN alpha torque limiters
are factory adjusted to the specified
disengagement torque, which is marked
on the coupling. The adjustment range
(min./max.) is indicated on the

adjust-

ment nut (1)

. The customer can adjust

the disengagement torque infinitely
within the

adjustment range (12)

by varying the pretension of the disc
springs. The adjustment range must not
be exceeded during the adjustment pro-
cess. After loosening the

lock screw

(11)

, the disengagement torque can be

adjusted using a suitable tool, e.g. a
torque adjusting wrench to DIN 1816.
The three locking screws

(11)

should

then be tightened again.

Important!

WITTENSTEIN alpha torque
limiters incorporate disc springs
with special spring character-
istics. Never exceed the max./
min. range of the disengage-
ment torque, which is located
along the downward slope of
this characteristic curve.

Quick

gearhead selection

recommended by WITTENSTEIN alpha. Please contact us if you require further assistance.

The quick gearhead selection feature is designed exclusively for calculating gearhead sizes approximately. Quick selection is not
a substitute for the detailed design feature! To select a specific gearhead, proceed as described in the Chapter ”Gearhead –
Detailed design“ or ”V-Drive – Detailed design“. For quick, convenient and reliable gearhead selection, we recommend using
WITTENSTEIN alpha’s cymex

design software.
