How to change the bearing of the crusher?

Remove the shell, take off the main shaft, fold down the ball bearing with a horse, replace the new ball bearing, use a copper tube to cover the shaft, hit the copper tube with a hammer to hit the new bearing in place, and then tighten the card pin.

The five major parts of the bearing are: inner ring, outer ring, rolling element, cage, and grease. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. In addition, lubricants have a great influence on the performance of rolling bearings, so lubricants are sometimes regarded as the fifth largest part of rolling bearings. 

The five major parts of the bearing have the following functions: 

1. The inner ring is usually tightly fitted with the shaft and rotates together with the shaft. 

2. The outer ring is usually matched with the bearing seat hole or the mechanical part shell to play a supporting role. However, in some applications, the outer ring rotates, the inner ring is fixed, or both the inner ring and the outer ring rotate. 

3. The rolling elements are evenly arranged between the inner ring and the outer ring by means of the cage. Its shape, size and quantity directly affect the bearing capacity and performance of the bearing. 4. The cage evenly separates the rolling elements, guides the rolling elements to move on the correct track, and improves the internal load distribution and lubrication performance of the bearing.
