Tungsten Carbide Ball for Universal Joint (1/2)

Universal joint like joint on human limbs, it is a kind of component that change the angle and achieve power transmission, which is also called universal connect. Universal joint can be usually seen in driving system gear in cars or some mechanical equipment, whose main role is to change the position of the shaft line direction. On the front-engine rear-wheel drive vehicles, the universal joint transmission device is installed between the transmission output shaft and the drive axle final drive input shaft; while the front-engine front-wheel drive vehicle is omitted, drive shaft, universal joint mounted between the drive and is also responsible for steering the front axle and the wheel axle.

According to elastic twist direction, it can be specifically divided into rigid and flexible universal joint. Flexible universal joint assembly is mainly composed of elastic rubber-like, temporarily go into details here. We discuss the most common rigid joints in constant velocity joints here. As the name implies constant input shaft and output shaft universal joint is connected is always equal to the instantaneous angular velocity of the transfer direction of movement section, which can be subdivided into fork-ball constant velocity joints and constant velocity joints ball basket. Fork-ball constant velocity joint consists of two fork ball with raceway and ball composition. It is unavoidable that the groove and ball will endure friction, impact and other interactions during the process, especially will probably be contacted with some corrosive liquid, which put higher requirements for the materials.
