Objective
In order to obtain optimal bearings starting torque, It is very important to control fixed-side support unit in appropriate preload. Under identical motor running condition , It will get optimal starting torque value .. Following are results.
Note
- There are axial clearance and weakness rigidity problem for bearings without or insufficient preload.
- Too great a preload on bearings can lead to overheating , and increase staring torque of the bearing. Therefore , It lead to reduce out efficiency for motor operation. It also causes increasing bearing temperature and reducing Bearing life.
