Driven side
•
Turn the hub in the direction of the drive.
!
Here the sleeve must not be axially displaced from its position of wear.
•
Mark sleeve (component 2) and hub (component 1) (see illustration 33).
•
Turn the hub (component 1) against the direction of drive and measure the circumferential backlash
S
max
.
•
When reaching the circumferential backlash
S
max
the coupling must be replaced.
Illustration 33: Marking of the hub and the sleeve
With a circumferential backlash of ≥
S
max.
[mm], the coupling must be replaced.
Reaching the limits for replacing depends on the operating conditions and the existing operating parameters.
!
In order to ensure a long service life of the coupling and avoid dangers with the use in
potentially explosive atmospheres, the shaft ends must be accurately aligned.
Please absolutely observe the displacement figures specified (see table 11). If the figures
are exceeded, the coupling will be damaged.
