Centralized lubrication structure of universal joint

Abstract

The invention discloses a centralized lubrication structure of a universal joint. The structure comprises parts and components including oil seals, oil sealing sleeves, a shaft sleeve, an oil pipe, the universal joint, oil pipe joints and the like, wherein the shaft sleeve is fixed to a position, which is close to the universal joint, of a driving shaft, and the shaft sleeve is in tight fit with a shaft and rotates at equal speed along with the shaft; an oil pipe joint mounting hole is formed in the shaft sleeve and is used for connecting the oil pipe joint. Two oil seals are assembled on the shaft sleeve at an interval, the oil sealing sleeves are assembled on the oil seals, the oil sealing sleeves are opened for installing the oil pipe joint and then is connected with the oil pipe, and the oil seals and the oil sealing sleeves are fixed and cannot rotate along with the shaft. An oil filling port is formed in an end cover of a needle bearing and is used for installing the oil pipe joint, the oil pipe joint of the shaft sleeve is connected with the oil pipe joint at the end cover of the needle bearing by the metal oil pipe, and the shaft sleeve is fixedly connected with a rotary shaft of the universal joint. According to the centralized lubrication structure, manpower is saved, the lubricating efficiency is improved, and the service life of the universal joint is prolonged.

Description

technical field [0001] The invention relates to the technical field of grease filling in a centralized lubrication system, in particular to a centralized lubrication structure of a universal joint. Background technique [0002] At present, the lubrication of universal joint bearings on mechanical transmission equipment is basically filled manually, which is not convenient for operation and maintenance. It is difficult to control the filling amount during the filling process, which is easy to cause waste of grease and environmental pollution. . The main reason is that the universal joint is located in the transmission part of the equipment, and it rotates at a high speed accompanied by axial and radial runout, which makes it inconvenient to install a centralized lubrication device. [0003] In view of the above, how to realize the automatic lubrication of the universal joint bearing, and at the same time accurately control the amount of grease filling, avoid the waste of gre...
