Abstract

The invention relates to a rolling bearing performance testing device based on the loadable alternating load of a crank connecting rod. The rolling bearing performance testing device comprises a workbench, a rotating shaft supporting mechanism, a rotating shaft, a driving motor and an alternating load loading unit, wherein the alternating load loading unit comprises a clamping block assembly, a first rotating motor and a second rotating motor, a first crank connecting rod transmission loading mechanism is arranged between the first rotating motor and the clamping block assembly, and a second crank connecting rod transmission loading mechanism is arranged between the second rotating motor and the clamping block assembly. Compared with the prior art, the rolling bearing performance testing device has the advantages that the first rotating motor and the second rotating motor can load alternating load on the rolling bearing in the clamping block assembly through the first crank connectingrod transmission loading mechanism and the second crank connecting rod transmission loading mechanism, so that the true working condition of the dynamic loading of the rolling bearing in the internalcombustion engine is simulated, and the accurate and reliable performance test result of the rolling bearing is guaranteed.

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 a crank connecting rod 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 piston-cylinder liner, piston ring-cylinder liner, crankshaft-bearing and cam-tappet. Among them, the crankshaft-bearing includes main bearing and connecting rod bearing (due to the working load of this type of bearing The size and direction of the internal combustion engine change with time, so it is usually called a dynamic load bearing), which i...
