Originally, constant velocity universal joints used in car production and car maintenance in my country mainly rely on imports, which cost a lot of foreign exchange every year. In order to develop my country's automobile industry, after more than ten years of research and development, the blank precision forging technology and production technology of the main parts of automobile constant velocity universal joints have been developed. Nowadays, there are many domestic large factories with this production technology, such as Wafangdian Hongda (ZWZ), Shanghai Na Tiefu (SDS), Hangzhou Wanxiang, Taizhou Jutai (BIK), Taizhou Hongli (LEE), Wenzhou Guansheng (GSP), Ningbo Wanhang and other domestic manufacturers. The ball cages produced by domestic manufacturers have been provided to domestic and foreign vehicle manufacturers! The production line consists of spherical shells, cylindrical shells, chemical sleeve precision forging lines and star sleeves, and three-way shaft temperature blocking forging lines.
The dust cover is also a key component in the ball cage product. Its main function is to prevent dust from entering the ball cage and prevent the butter in the ball cage from flowing out. Special high-temperature resistant grease must be used in the ball cage, and it cannot be replaced by other greases.
The composition of the outer ball cage:
1. Bell housing
2. Inner star wheel
3. Cage
4. Steel ball
5. Dust cover
6. Clamp ring
7. Grease (different from ordinary butter, the main component is molybdenum disulfide).
The composition of the inner ball cage:
1. Bell housing
2. Trident bearing or steel ball. (There are two types, here)
3. Dust cover
4. Clamp ring
5. Grease (different from ordinary butter, the main component is molybdenum disulfide).
