Maintenance
9.4 Inspection and maintenance
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.
Rotor can fall out
If the machine is in a vertical position, the rotor can fall out while work is being performed on
the locating bearing. This can result in death, serious injury or material damage.
Support or relieve the rotor when carrying out work with the machine in a vertical position.
9.4.8
Cleaning
Cleaning the grease ducts and spent grease chambers
The spent grease collects outside each bearing in the spent grease chamber of the outer bearing
cap. When replacing bearings, remove the spent grease.
Dismantle the bearing cartridges to replace the grease in the lubrication duct.
Cleaning the cooling air ducts
Regularly clean the cooling air ducts through which the ambient air flows.
The frequency of the cleaning intervals depends on the local degree of fouling.
Damage to the machine when cleaning with compressed air or water jets
• Do not direct compressed air or water jets in the direction of the shaft outlet or machine
openings.
• Avoid direct impact of compressed air and water jets on sealing elements of the machine.
