Tungsten Carbide Ball for Universal Joint (2/2)

Tungsten carbide ball is composed of hard phase WC and binder phase Co. It has higher hardness, strength, excellent wear resistance and chemical stability, which is the ideal material for universal joint. In the arc type universal joint, the active fork ball and do some carbide groove driven fork mounted four synthetic carbide ball raceway can accommodate four carbide balls. Besides, there is a spherical ball mounted in the center of the groove as centering ball. Straight groove raceway-type universal joint in the two fork ball with carbide straight grooves, straight grooves and each axis is inclined relative to the center line and the same tilt angle and symmetrical to each other. Built in the raceway between the two fork ball has four tungsten carbide balls.

Velocity joint cage can be divided into stationary and scalability ball basket universal joints according to the movement of the universal joint axial direction. Viewed from the structure, fixed cage universal joints are composed of spline, star sets, curved groove. Star spherical shell fitted jacket and synthesized six races, each mounted in each race a carbide ball and keep cage carbide ball inside in the same plane. It powered by a drive shaft through a spherical shell and tungsten carbide ball. The structural feature of scalability ball basket universal joints is the inner wall of the cylindrical shell of the star and the external cylindrical sleeve made straight slot, built-in two raceways fitted together after the formation of cemented carbide ball. Star set bore splined for connection with the input shaft, which allows relative movement of the tubular sleeve in the axial direction. Overall, due to high hardness, high strength, wear and corrosive resistance, tungsten carbide ball has a broad application prospect in universal joints.
