Problems solved by technology

Cross shaft universal joint cross shaft will generate additional dynamic load during 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 this type of universal joint has complex structure, high processing accuracy requirements, high quenching hardness, high production cost, and small bearing capacity. Disadvantages such as constrained range

Abstract

The invention relates to a single-linkage, damping and impact-resisting non-centering type constant-angular-velocity cardan joint. The single-linkage, damping and impact-resisting non-centering type constant-angular-velocity cardan joint comprises an input shaft, a cardan joint body, an intermediate shaft, an output shaft and fixing bearings. The two sets of fixing bearings are connected with one end of the input shaft and one end of the output shaft correspondingly. The other end of the input shaft is connected with the cardan joint body, and a three-fork rod of the cardan joint body is connected with one end of the output shaft through a spline. The cardan joint body comprises sliding block assemblies, a main cardan joint body and the three-fork rod. The three sliding block assemblies are arranged, and three sliding grooves are formed in the sleeve wall of a sleeve and distributed in a 120-degree manner. The three sliding block assemblies are arranged in the sliding grooves correspondingly. When a certain deflection angle exists between the input shaft and the output shaft, through the mutual connection relation, constant-angular-velocity transmission is guaranteed, and large-deflection and large-torque transmission is achieved. The single-linkage, damping and impact-resisting non-centering type constant-angular-velocity cardan joint has the obvious beneficial effects of being simple in structure, low in manufacturing cost, convenient to install, good in synchronization performance, high in transmission capability, resistant to impacts and good in buffering effect.

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 ...
