Fretting against the fretting bearings, should take the following measures:
1) the use of bearing the machine should be far away from the external vibration source, or open anti-vibration groove to prevent vibration from the foundation to the bearings;
2) The machine should be in the transport shaft brake does not turn, or the bearings can only rotate in one direction, and the shaft lock so that no axial movement;
3) When using grease lubrication, the consistency of the grease should be low, but oil lubrication is the best choice。 The viscosity of the oil is about 0。1 Pa ? s。
4) to the extent possible, the bearing clearance should be made smaller, or pre-interference installation.
