Radial sliding bearing bush temperature field and pressure field test platform and measurement method

Abstract

The invention provides a radial sliding bearing bush temperature field and pressure field test platform, which comprises a spindle fixing device, a driving system, a transmission device, a radial force loading device and a radial sliding bearing signal acquisition system, wherein the spindle fixing device comprises two sets of rolling bearing seats, a set of radial sliding bearing seat, a first slip and a base; the spindle passes through the first rolling bearing seat, the radial sliding bearing seat and the second rolling bearing seat sequentially, and the two rolling bearing seats are fixedon the base; the first slip comprises a first sliding rail and a first sliding block, the bottom part of the radial sliding bearing seat is fixedly connected with the first sliding block, the first sliding rail is fixed on the base, and the radial sliding bearing seat radically slides on the first sliding rail. The two rolling bearing seats are symmetrically distributed at two ends of the slidingbearing seat to support the spindle, the sliding bearing seat generates horizontal radial sliding under effects of a horizontal radial force, and the radial sliding bearing bush applies a uniform horizontal radial force to the spindle journal.

Description

technical field [0001] The invention relates to the research on the temperature field and the pressure field of the radial sliding bearing bush working face, in particular to a test platform and a measuring method for the temperature field and the pressure field of the radial sliding bearing bush. Background technique [0002] Modern enterprises are making rapid progress, the bearing-rotor system is also developing rapidly, the operating speed of rotating equipment is getting higher and higher, and the stability of the system is becoming more and more concerned by everyone, so how does the development of bearings meet The role it plays in the bearing-rotor system is crucial. Most of the rotating equipment now uses sliding bearings. Compared with rolling bearings, sliding bearings have obvious characteristics. Their structures are relatively simple, their performance against system vibration is better, and their operation accuracy is very high. They can be used in heavy-duty ...

AI Technical Summary

Problems solved by technology

The pressure and temperature distribution of the bearing bush has a great influence on the performance of the bearing. It will affect the installation and fit of the bearing, affect the working clearance of the bearing, and affect the performance of the lubricant, etc.
