High-speed bearings are higher than low-speed bearings, smaller surface roughness. With the rapid development of technology, high-speed bearings are also more widely used, but high-speed bearing is often led to: lubricant is scattered, it is difficult to attach, and the centrifugal force has caused sharp increase in contact stress, friction increases, and heat generation, etc. And other issues
1. Cause: The bearing precision is low. Workaround: Select the predetermined precision level of the motor bearings.
2. Cause: The spindle is bent or different hearts of the box. Workaround: Repair the spindle or the box.
3. Cause: The belt is too tight. Workaround: Adjusting the belt to make the tight appropriate.
4. Reason: Poor lubrication. Workaround: Select the gauge lubrication material and clean it properly.
5. Cause: The quality of assembly is low. Workaround: Improve the quality of assembly.
6. Cause: Bearing inside and outside running circle. Workaround: Replace the Motor Bearing and Related Wear Parts.
7. Cause: The axial force is too large. Workaround: Cleaning, corrected the sealing mouth ring clearance requirements between 0.2 to 0.3 mm, correct the impeller balance hole diameter and the check sediment.
8. Cause: Bearing is damaged. Solution: Replace the bearing.
The shaft parts of the machine tool, especially the spindle, generally inserted with the rolling bearing or sliding bearing group, and rotate with a high speed, sometimes high heat. If this phenomenon is not excluded in time, it will lead to heat in the air of the motor, and generate heat deformation in the temperature of the corresponding parts of the machine. It will make the main shaft and the tail frame, which will not only affect the accuracy and processing accuracy of the machine. And will burn the bearing.
