Automobile ball cage is divided into inner ball cage and outer ball cage, also known as "constant velocity universal joint". It is an important part of car transmission system. Its function is to transfer the engine power from the transmission to the two front wheels to drive the car at high speed. Automobile ball cage is generally composed of bell shaped shell, Trident bearing or steel ball, dust cover, belt ring, grease, etc.

 

If there is no professional inspection equipment, it is necessary to check the automobile ball cage, mainly including:

 

1. The dimensions of internal and external spline and thread affect the loading size of the cage,

 

2. Check the size of the outer cage oil seal. Generally, different types of cage oil seal are different,

 

3. Check whether the inner snap ring groove of the internal spline is correct, and the width of the snap ring groove affects the movement of the ball cage on the half shaft after loading;

 

4. Insert a shaft into the internal spline and swing the cage to see if the rotation is flexible;

 

5. Materials, heat treatment performance, etc. need special equipment to check.
