5.2.15 V-belts (belt drives)
WARNING
Entanglement hazard
• The protective cover must be correctly installed before re-commissioning.
V-belt pulleys should be visually inspected at regular intervals. In case of severe signs of wear, a V-
groove and profile gauge should be used as an aid to determine the degree of wear. Dirt on the belt
pulley or the belt causes friction losses. Therefore, always keep these components clean and dry.
Check the condition of the V-belts. Replace cracked or brittle V-belts. If one or more V-belts fail in a
multiple groove drive, a new set of V-belts must be fitted. V-belts from different manufacturers must
not be combined to form a set of belts. Before installing new V-belts, it is essential to check the
condition of the V-belt pulleys.
After a running time of approx. 4-5 hours with the drive under full load, the tension of the V-belts must
be checked with a frequency measuring device and corrected as necessary.
