Hints and instructions regarding the use in
hazardous areas
5.2 checking of torsional backlash
!
C A U T I O N !
To check the torsional backlash the turned off drive aggregate must be secured against
unintended turning on.
•
Turn the hub in opposite direction to the direction of drive.
!
C A U T I O N !
Here the elastomer part may not be axially displaced from its wear position.
•
Mark elastomer part and hub (see picture 9).
•
Turn the hub in the direction of drive and measure
the torsional backlash
∆
S
max
.
•
When reaching the torsional backlash
∆
S
max
the
elastomer part must be exchanged.

5.3 Approximate values of wear
If the torsional backlash is
≥
∆
S
max.
[mm] / friction
≥
X
max.
[mm], the elastomer part must be exchanged.
The reaching of the exchange values depends on the operating conditions and the existing operating parameters.
!
C A U T I O N !
In order to ensure a long lifetime of the coupling and to avoid dangers regarding the use in
hazardous areas, the shaft ends must be accurately aligned.
Please absolutely observe the displacement figures indicated (see table 5). If the figures are
exceeded, the coupling is damaged.
