We all know that universal joints are a very important part of a car, and there are many types of universal joints, so many people do not know how to choose universal joints at the beginning and choose custom universal joints . There is also a cross-shaft rigid universal joint in the universal joint. Today, let's first understand the cross-shaft rigid universal joint.
The cross-shaft rigid universal joint is composed of the universal joint fork, cross shaft, needle bearing, oil seal, sleeve, bearing cover, and other parts. The working principle is: one of the rotating forks drives the other fork to rotate through the cross shaft, and at the same time, it can swing in any direction around the center of the cross shaft. The needle roller in the needle roller bearing can rotate on its own during rotation to reduce friction. The shaft connected with the input power is called the input shaft (also called the driving shaft), and the shaft output through the universal joint is called the output shaft (also called the driven shaft). When working with an angle between the input and output shafts, the angular velocities of the two shafts are not equal, which will cause torsional vibration of the output shaft and the transmission components connected to it and affect the life of these components.
In addition to the cross-axis rigid universal joint, there is the universal joint for truck , precision universal joint, etc., so you still need to know more when choosing.
