8 Maintenance
When they are delivered, Lenze gearboxes and geared motors are filled with a drive and
type-specific lubricant so that they are ready for production. This initial filling
corresponds to a lubricant from the column of the respective Lenze gearbox type. When
the order isplaced, the mounting position and the design arethe decisive factors forthe
lubricant amount.
Note!
Gearboxes of sizes 03 and 04 are lubricated for life. Due to the low
thermal load, no lubricant change is required.
8.1 Maintenance intervals
• The mechanical power transmission system is free of maintenance.
• Gearboxes as of size 05 (pre-stages as of size 06) require regular lubricant
replacement.
– The type of lubricant is indicated on the nameplate. Replace the lubricant only
with the same type.
– The lubricant maintenance interval depends on the oil temperature, see Fig. 13.
• Shaft seals and roller bearings:
– The service life depends on the operating conditions.
– Replace seals in case of leakage to a void consequential damage.
Note!
When changing the lubricant, Lenze recommends also changing the
grease packing of the bearings and replacing the rotary shaft seals!
Stop!
For drive systems: Also observe the maintenance intervals for the other
drive components!
