When we first come into contact with universal joints, we will find that there are many types and models of universal joints, so it will be more difficult to distinguish, and we don't know which type of universal joint we need. At this time, in addition to understanding, there is another way to custom universal joints , which can quickly solve your troubles. Today we are talking about quasi-constant velocity universal joints.
Quasi-constant velocity universal joints can be divided into a) Double quasi-constant velocity universal joints. Refers to the universal joint when the length of the transmission shaft in the universal joint constant velocity transmission device is shortened to the minimum. b) Bump type quasi-constant velocity universal joint. It is composed of two universal joints and two bumps of different shapes. The two projections are equivalent to the intermediate transmission shaft and two cross pins in the double universal joint device. c) Three-pin shaft type quasi-constant velocity universal joint. It consists of two three-pin shafts, an active eccentric shaft fork, and a driven eccentric shaft fork. d) Spherical roller type quasi-constant velocity universal joint. It is composed of a pin shaft, a spherical roller, a universal joint shaft, and a cylinder. The roller can move axially in the groove to play the role of the telescopic spline. The roller contact with the groove wall can transmit torque.
There is universal joint for truck , variable speed universal joints, and so on in the universal joints. There are many models and types.
