An apparatus for studying a sliding bearing under different working conditions

Abstract

The invention discloses an apparatus for studying a sliding bearing under different working conditions. The apparatus mainly comprises a main shaft, a motor, a motor base, a shaft coupling, an antifriction bearing supporting device, a sleeve, a bearing bush, a positioning disc, a thermal imager, a fuel tank, a pedestal and a computer. When researches are carried out under different working conditions, the sleeve can be dismounted and subjected to damages to different degrees. The installation is simple and time can be saved. Furtherly, the apparatus utilizes the thermal imager which can be connected with a computer so as to convert temperature signals into a temperature distribution image. The temperature distribution and temperature changes of an oil film of the bearing bush can be observed on a display. The static behaviors of the sliding bearing can be studied according to the temperature changes and distribution under different working conditions. The apparatus designed by the invention is simple in structure and convenient to assemble. The apparatus substantially reduces experiment costs, lowers an experiment difficulty degree and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of sliding bearings, in particular to a device capable of studying sliding bearings in different working conditions. Background technique [0002] As sliding bearing equipment is more and more widely used in life, the research on its faults is also getting more and more in-depth. We can conduct a series of static analysis on sliding bearings, among which the friction and wear of bearings is an important content. We need to study the static characteristics of sliding bearings with different wear degrees, but this requires a large number of sliding bearings to do the test, which is time-consuming and increases the cost of the test. For example, when we study the oil film distribution of sliding bearings under two different wear states, we need to replace the shaft or move the position of the sliding bearing, which obviously increases the difficulty of the test. Therefore, improving the installation method and structur...

Problems solved by technology

[0003] In addition, when detecting the temperature of the oil film, most of them use temperature sensors or infrared thermometers, but this cannot accurately analyze the temperature distribution of the entire oil film. The measurement range is limited and the error is relatively large, which will affect the sliding bearing. Static Characteristics Study Results
