Rolling bearing performance test device based on belt drive with radial alternating load

Abstract

The invention relates to a rolling bearing performance test device based on belt drive with radial alternating load, comprising a workbench, a rotary shaft support mechanism, a rotary shaft, a drivingmotor and a radial alternating load application unit; the radial alternating load application unit comprises a loading unit support, a clamp block component and a pair of synchronous belt radial loading mechanisms mutually perpendicularly arranged on the loading unit support; each synchronous belt radial loading mechanism comprises a first rotary motor, a second rotary motor, a first synchronousbelt component, a first spring loading component, a second synchronous belt component and a second spring loading component. Compared with the prior art, the rolling bearing performance test device based on belt drive with radial alternating load has the advantages that the first rotary motor and the second rotary motor can apply radial alternating load to a rolling bearing in the clamp block component respectively through the first spring loading component and the second spring loading component so as to simulate true working conditions of a dynamic load rolling bearing in an internal combustion engine, and it is ensured that rolling bearing performance test results are accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and relates to a rolling bearing performance test device for applying radial alternating loads based on belt transmission. Background technique [0002] As power equipment, internal combustion engines have been widely used in many industries such as automobiles, ships, aircraft, tanks, railway locomotives, agricultural machinery, construction machinery, generator sets, etc., and occupy a very important position in the national economy. The internal combustion engine includes several pairs of important friction pairs such as the conveyor belt fixed block-cylinder liner, the conveyor belt fixed block ring-cylinder liner, the crankshaft-bearing and the cam-lift rod, among which the crankshaft-bearing includes the main bearing and the connecting rod bearing (due to the The magnitude and direction of the working load of the type bearing change with time, so it is usually called a d...

AI Technical Summary

Problems solved by technology

At present, the traditional rolling bearing test device has a single loading characteristic and cannot be loaded with variable loads. In real internal combustion engines, dynamically loaded rolling bearings often work under alternating loads. Therefore, traditional rolling bearing performance test devices cannot carry out internal combustion engine loaded rolling bearing tests.
