The centers of the force-transmitting steel balls are located in the plane.It was installed in a raceway which was consists of a spherical outer ring, and a groove on the outer spherical surface of a star-shaped inner ring.
The center of the two balls coincides with the center of the universal joint. In order to ensure the center of all steel balls is on the bisector of the angle between the two axes, the steel balls are installed in the ball cage, so when the angle between the two shafts is changing, the transfer point can always keep same .so as ,the speed of main and driven shaft can realize synchronized.
That is why we also call it ball caged type universal joint
Bellow is the parametes of this ball caged type shaft coupling
We are a professinal shaft coupling and cv joint manufacture in China ,and have gained 80% market share especial for the small precision cv joint ,such as our WX WXD .WSP ,GR HR ,SWP QC QWL those kinds of shaft coupling .In a words ,our product can be divided in to four catagroies :
--universal shaft coupling
---Aluminum Flexible Coupling
Then how we ensure our qualitly ?
