Ball-type transmission device for universal joint

Abstract

The invention discloses a ball-type transmission device for a universal joint. The device comprises a spherical shell, a star-like sleeve and a ball holder. The ball holder is movably installed in thespherical shell through a guide part, the star-like sleeve is movably installed in the ball holder, and a transmission rod is installed at the extension end of the star-like sleeve through a thread structure; a driving shaft is fixedly installed at the bottom of the spherical shell through a thread part, a hydraulic rod is installed at the bottom of the driving shaft through a bolt, and a connector is installed at the bottom of the hydraulic rod through a thread structure. According to the ball-type transmission device, a protection cover is installed at the outer side of the transmission rodto add the protection structure of the device, the protection performance of the device is improved, through the protection cover, the junction between the transmission rod and an extension rod can be effectively protected, the situation is avoided that the transmission rod and the extension rod are wound with foreign matter during rotation, the safety of the device is improved, and the transmission efficiency of the device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of universal joints, in particular to a ball cage type universal joint transmission device. Background technique [0002] The universal joint is the universal joint, which is a machine that realizes variable-angle power transmission. It is used to change the position of the transmission axis. It is the joint part of the universal transmission device of the automobile drive system. The universal joint is combined with the transmission shaft It is called universal joint transmission. [0003] The defects in the existing ball cage type universal joint transmission device are: [0004] 1. The existing ball cage type universal joint transmission device cannot carry out synchronous transmission, which leads to the phenomenon that the roller transmission is not uniform when the car is driven, and reduces the efficiency of the universal joint transmission; [0005] 2. The existing ball cage type universal joint tr...
