Example Embodiment

[0022] As shown in Figure 1, the left bearing I and the right bearing III are supporting bearings and are fixed on the test platform by locating pins. The middle bearing II is the load object used for performance testing. It is suspended on the shaft IV and is easy to install and center. , Eccentricity measurement can also be achieved.

[0023] As shown in Figures 2, 3, 4, and 5, the static pressure oil circuit of the left bearing I is supplied by a high-pressure pump with static pressure oil, which is injected into the left static pressure oil through the static pressure oil inlet 18 on the left bearing I The oil hole 10 passes through the static pressure oil hole 21 and then enters the static pressure oil cavity 22, and establishes a static pressure bearing oil film in the bearing area to withstand the external load; the dynamic pressure oil path is the dynamic pressure oil passing through the left bearing I. The pressure oil hole 9 flows through the dynamic pressure oil hole 1...

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 operation, have small frictional resistance and high operating efficiency, and are widely used in major mechanical equipment with high precision installation, but because of their extremely high requirements High, often cause insufficient oil supply due to poor oil circuit design, causing direct contact with metal parts to cause friction and wear, resulting in burns. Therefore, it is necessary to improve and study the oil circuit st...
