9.2.3 Bearing replacement interval
The bearings are subject to wear and must be replaced after a defined number of operating
hours.
Note
Bearing replacement interval dependency on the operating conditions
Bearing change intervals can be extended if the motor is operated under favorable
conditions, e.g. low or medium speeds, low radial forces (transverse forces), vibration load.
Unfavorable conditions, e.g. high vibration/shock loads, frequent reversing operation, reduce
the bearing replacement intervals t
LW
by up to 50%.
In the case of operating conditions listed by the operator, the bearing service life for the
bearings in the gearbox can be calculated with the help of the SIZER configuring tool.
If there are no specifications, replace the bearings in the gearbox when you detect changes
in the vibration and noise characteristics.
With medium loads, replace the motor bearings, the shaft sealing ring on the motor side, and
the encoder after 25 000 operating hours.
9.2.4 Checking and changing lubricants
9.2.4.1 Checking the oil level
Note
Check the oil level at operating temperature
If the temperature rises, the volume of the gearbox oil increases.
In the case of greater temperature differences and filling quantities, the volume can vary by
several liters.
•
Check the oil level approximately 30 minutes after switching off the converter and while it
is still slightly warm.
