Note
When servicing a three-phase machine, it is generally not necessary to dismantle it.
The machine only has to be dismantled if the bearings are to be replaced.
9.4 Maintenance
9.4.1 Re-greasing
For machines with regreasing system, relubrication intervals, grease quantity and
grease grade are provided on the lubricant plate. Additional data can be taken from
the main machine rating plate.
Grade of grease for standard motors (IP55) UNIREX N3 - ESSO.
Note
It is not permissible to mix different types of grease.
Prolonged storage periods reduce the useful lifetime of the bearing grease. Check
the condition of the grease if the equipment has been in storage for more than 12
months. If the grease is found to have lost oil content or to be contaminated, the
machine must be immediately relubricated before commissioning. For information on
permanently-greased bearings, please refer to the section titled Bearings (Page 140).
Procedure
To relubricate the roller bearings, proceed as follows:
1. Clean the grease nipples at the drive end and non-drive end.
2. Press-in the specified grease and amount of grease according to the data
stamped on the lubrication plate.
– Please observe the information on the rating and lubricant plates.
– Regreasing should be carried out when the motor is running (max. 3600 rpm).
The bearing temperature can rise significantly at first, and then drops to the normal
value again when the excess grease is displaced out of the bearing.
