Comprehensive test device of oil film bearing

Abstract

A comprehensive test device of an oil film bearing belongs to the technical field of the oil film bearing. The structure is as follows: a left bearing, a middle bearing and a right bearing are sequentially arranged from left to right; a shaft connected with a motor through a coupling is arranged inside a bearing hole; an oil path of the left bearing is provided with a dynamic press-in oil hole and a static press-in oil hole at upper and lower top points of a bearing block; oil grooves are arranged inside axle holes at the left end and the right end; the bottom part of each oil groove is communicated with an oil return hole; the dynamic press-in oil hole and a dynamic press-in oil cavity are arranged at the upper part of a vertical center line of a bush; the static press-in oil hole and a static press-in oil cavity are arranged at the lower part; the oil grooves communicated with the oil return hole are arranged on the inner surfaces of the axle holes of a left end cover and a right end cover; the oil path of the middle bearing is respectively provided with the dynamic press-in oil hole at the front and rear top points of the bearing block; the oil grooves are arranged inside the axle holes at the left end and the right end; the bottom part of each oil groove is communicated with the oil return hole; the dynamic press-in oil hole and the dynamic press-in oil cavity are arranged at the front end part and the rear end part of a radial center line of the bush; and the oil grooves communicated with the oil return hole are arranged at the inner surfaces of the axle holes of the left end cover and the right end cover.

Description

technical field [0001] The invention belongs to the technical field of oil film bearings, and in particular relates to a comprehensive oil film bearing test device. Background technique [0002] Oil film bearings are sliding bearings that use oil film bearing oil as the lubricating medium, fluid lubrication principle as the mechanism, and the power of the rotating shaft to bring the lubricating oil into the wedge-shaped gap to form a pressure oil film to bear the external load. Oil film bearings avoid friction and wear between metal parts during stable operation, have small frictional resistance and high operating efficiency, and are widely used in high-precision major mechanical equipment, but because of their extremely high requirements for the design of oil circuit structures Insufficient oil supply is often caused by poor oil circuit design, which causes friction and wear of metal parts in direct contact, resulting in burn failure. Therefore, it is necessary to improve ...
