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 radial alternating load loading device used for a bearing tester based on synchronous belt drive. The bearing tester comprises a rotating shaft (1). A tested bearing (2) isinstalled on the rotating shaft (1). The loading device comprises a clamp (3) and a rotating motor-a synchronous belt drive mechanism-a spring component which are arranged around the clamp (3) in an axial symmetry and radial symmetry way. The synchronous belt drive mechanism comprises a coupler (51), a lead screw bearing (52), a lead screw nut (53), a lead screw (54) and a bearing pedestal (55). The rotating motor is connected with the lead screw bearing (52) and the lead screw (54) through the coupler (51). The lead screw (54) is provided with the lead screw nut (53). The bottom part of the lead screw (54) is provided with the bearing pedestal (55) and connected with the spring. Compared with the devices in the prior art, the device has the advantages that the actual condition load of theinternal combustion engine can be realized.

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 a synchronous belt drive. Background technique [0002] Internal combustion engines are widely used in many industries such as automobiles, ships, airplanes, tanks, railway locomotives, agricultural machinery, construction machinery, generator sets, and so on. As power equipment, they occupy a very important position in the national economy. The internal combustion engine includes several important pairs of friction pairs, such as piston-cylinder liner, piston ring-cylinder liner, crankshaft-bearing and cam-lifter. Among them, crankshaft bearings include main bearings and connecting rod bearings (due to the working load of this type of bearing The size and direction of the engine change with time, so it is usually called dynamic load bearing), which is one of the most critical friction pair...
