Single-linkage, damping and impact-resisting non-centering type constant-angular-velocity cardan joint

Abstract

The invention relates to a non-centering constant angular velocity universal joint with single-link vibration reduction and impact resistance, comprising: an input shaft, a universal joint, an intermediate shaft, an output shaft, and a fixed bearing; the fixed bearing has two sets, which are respectively connected to the fixed bearings. The input shaft is connected to one end of the output shaft, the other end of the input shaft is connected to the universal joint, and the tripod of the universal joint is splined to one end of the output shaft; the universal joint The joint includes: a slider assembly, a universal joint body and a tripod rod; there are three sets of the slider assembly, and three sets of slide grooves are opened on the wall of the sleeve, which are distributed at 120°; the three sets of slider assemblies are respectively Installed in the chute; in the present invention, when there is a certain deflection angle between the input shaft and the output shaft, the mutual connection relationship not only ensures the transmission of constant angular speed but also realizes the transmission of large deflection angle and large torque, and has the advantages of simple structure and easy fabrication. Low cost, easy installation, good synchronization performance, strong transmission capacity, impact resistance, and good buffering effect are significant advantages.

Description

technical field [0001] The invention relates to the field of universal joints, in particular to a non-centering type constant angular velocity universal joint with single-link vibration reduction and shock resistance. Background technique [0002] In the process of mechanical transmission, when there is a certain angle between the axes of the driving shaft and the driven shaft, it is necessary to use the universal joint to transmit the torque. At present, there are many types of universal joints used in the machinery industry, among which the most commonly used ones are cross-type universal joints and cage-type universal joints. The cross shaft universal joint cross shaft will generate additional dynamic load in the transmission, causing shock, vibration and noise, so it is not suitable for high speed and excessive angle between shafts. Although the ball cage type universal joint can realize the transmission of large torque and is a constant angular speed transmission, but ...
