Attaching the output elements
This chapter provides important information for pulling on output elements.
NOTICE
Damage to the motor due to runout on the shaft extension
Blows and pressure applied to the shaft extension can damage the gearbox.
•
Mount the geared motor without applying blows and forces to the shaft extension.
NOTICE
Damage to shaft sealing rings when heating up
When pulling on input and output elements by applying heat, shaft sealing rings can be
damaged.
•
Protect the shaft sealing rings using a thermal shield to prevent the temperature from
increasing to above 100 °C due to radiant heat.
Note
When pulling on elements, distortion can damage the gearbox.
•
Use suitable tools or fixtures when pulling on input and output elements.
•
When pulling on or shrinking an element onto the output shaft, ensure that the maximum
allowable static axial forces of the output bearing are not exceeded.
Pulling on instructions
Pull on input and output elements in such a way as to minimize the stress on shafts and
bearings due to cantilever forces.
Optimum
Unfavorable
low stress on shafts and bearings
high stress on shafts and bearings
