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.

Abstract

The invention relates to an antifriction bearing performance testing apparatus based on belt drive and being able to load alternating load. The antifriction bearing performance testing apparatus includes a work bench, a rotating shaft supporting mechanism, a rotating shaft, a driving motor and an alternating load loading unit, wherein the alternating load loading unit includes a clamp block assembly, a first rotary motor and a second rotary motor; a first synchronous loading mechanism is arranged between the first rotary motor and the clamp block assembly; and a second synchronous loading mechanism is arranged between the second rotary motor and the clamp block assembly. Compared with the prior art, in the antifriction bearing performance testing apparatus based on belt drive and being able to load alternating load, the first rotary motor and the second rotary motor can load alternating load to the antifriction bearing in the clamp block assembly through the first synchronous loading mechanism and the second synchronous loading mechanism respectively, so as to simulate the real working condition of the dynamic load antifriction bearing in an internal combustion engine, thus guaranteeing that the antifriction bearing performance test result is 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 based on belt transmission that can be loaded with alternating loads. 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...
