Maintenance

BA S’belt KE EN 1.0

6 Maintenance

6.1 Maintenance intervals

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.
