Problems solved by technology

At present, the loading characteristics of the traditional bearing test device are single, and the loading of variable loads cannot be realized. In the real internal combustion engine, the dynamic load bearing is often under alternating load, so it is difficult for the traditional bearing test loading device to realize the alternating load of the dynamic load bearing of the engine. load

Abstract

The invention relates to a rack-and-pinion-transmission-based radial alternating load loading device for a bearing testing machine. The bearing testing machine comprises a rotating shaft (1); and a tested bearing (2) is installed at the rotating shaft (1). The loading device is composed of a clamp (3) and a rotary motor-rack-and-pinion-transmission-mechanism-spring assemblies arranged around the clamp (3) in axial symmetry and radio symmetry; the rotary motor-rack-and-pinion-transmission-mechanism-spring assembly arranged in axial symmetry applies an axial alternating load on the tested bearing (2) in the clamp (3); and the rotary motor-rack-and-pinion-transmission-mechanism-spring assembly arranged in radial symmetry applies a radial alternating load on the tested bearing (2) in the clamp(3). Compared with the prior art, the rack-and-pinion-transmission-based radial alternating load loading device has advantages of being capable of realizing the real working condition load of the internal combustion engine and the like.

Description

technical field [0001] The invention relates to a loading device for a bearing testing machine, in particular to a radial alternating load loading device for a bearing testing machine based on rack and pinion transmission. Background technique [0002] Internal combustion engines are widely used in automobiles, ships, airplanes, tanks, railway locomotives, agricultural machinery, construction machinery, generator sets and other industries. As power equipment, they occupy a very important position in the national economy. The internal combustion engine includes several important friction pairs such as piston-cylinder liner, piston ring-cylinder liner, crankshaft-bearing and cam-tappet. Among them, the crankshaft bearing, including the main bearing and the 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 is one of the most cri...
