The 5-280X PRECISION 334 universal joint has obvious elasticity in the torsional direction. The flexible universal joint is mainly composed of rubber elastic elements, bushings, bolts and centering devices provided to ensure dynamic balance at high speed. The working principle is that when the torque acts on the input shaft, the torque passes through the three flanges and connecting bolts on the input shaft and the universal joint fork, and then is transmitted to the rubber block, and the torque acts on the output through the rubber block. Universal joint flange on the shaft. Due to the elasticity of the rubber block, a certain angle between the two shafts is allowed.
The first type is a ball-fork type constant velocity universal joint. It is a universal joint composed of a ball fork with a raceway and a steel ball. Among them, the arc groove raceway ball fork type universal joint means that the steel ball raceway on the ball meaning is a circular arc type universal joint, which is characterized by the fact that there are round on the active fork and driven fork of the ball fork The arc grooves form four steel ball raceways after the two are assembled, and a total of four steel balls are accommodated in the raceways. Straight grooves are formed on the two ball forks, and each straight groove is inclined with respect to the center line of the shaft, and the inclined angles are the same and symmetrical to each other.
The second type is the ball cage type constant velocity universal joint. According to whether the universal joint can move in the axial direction, it can be divided into an axial non-retractable ball cage type universal joint and a telescopic ball cage type universal joint. The inner surface of the star sleeve of the fixed ball cage type universal joint is connected to the drive shaft with an internal spline. Its outer surface is made with six arc grooves as the inner raceway of the steel ball. The outer raceway is made in Spherical shell on the inner surface. The structural feature of the telescopic ball cage type universal joint is that a cylindrical straight groove is formed on the inner wall of the cylindrical shell and the outer part of the star sleeve, and a steel ball is installed in the raceway formed after the two are assembled. The steel ball is also installed in the hole of the cage. The inner hole of the star sleeve is splined to connect with the input shaft. This structure of 5-7126X 6H2577 universal joint allows the star sleeve to move relative to the simple shell in the axial direction.
