Insufficient or excessive lubrication, the lubricant contains impurities, the load is too large, will cause bearing damage. Insufficient clearance will lead to the normal use of bearings, but improper rapid operation will also lead to damage to the use of bearings.
Bearing at high speed rotation, especially when the speed is close to or exceeds the limit speed, should pay attention to the following matters:
1. Use precision bearings;
2. analysis of bearing internal clearance (considering the reduction of bearing internal clearance caused by temperature rise);
3. Analyze the material type of the cage (for high-speed rotation, copper alloy cage is suitable for use. There are also synthetic resin cages suitable for high-speed rotation);
4. analysis of the lubrication method (suitable for high-speed rotation of circulation lubrication, jet lubrication, oil mist lubrication and oil and gas lubrication lubrication).
