Stop!
With drive systems: Please observe the maintenance intervals of the other drive components, too!
l Wide V-belts have a natural wear which depends on several factors:
– On-time
– Load type
– Speeds
– Ambient temperature
As a guide value Lenze recommends to check the wide V-belt for wear and fissures every 4 to 6
months and replace it, if necessary.
l Variable speed pulleys are maintenance-free.
Note!
While checking the wide V-belt Lenze recommends to inspect visually the variable speed pulleys.
Check if the movable disc can be moved and the state of the disc face. Run-in grooves on the disc
face caused by wear reduces the belt life.
