Axlebox bearing and grounding device comprehensive performance test bench

Abstract

The invention relates to an axle box bearing and earthing device comprehensive performance test-bed comprising a base foundation and a machinery device arranged in the base foundation; the machinery device mainly comprises an equipment mounting platform, a transverse counterforce bearer, a transverse actuator, a tested bearing and exciting beam device, no.1 and no.2 support gantry frameworks, no.1 and no.2 framework simulators, a power motor, and no.1 and no.2 vertical exciting actuators; the test-bed can simulate the speed and vibration conditions of the rail vehicle axle box bearing and shaft end earthing device running on a real line, can provide truly and reliable testing environments for the rail vehicle axle box bearing and shaft end earthing device bench tests, thus solving the problems that the rail vehicle cannot carry out motor unit axle box bearing reliability test in real operation and the shaft end earthing device life examination test. The test-bed is simple in structure, and can perform the axle box bearing and earthing device comprehensive performance test.

Description

Technical field [0001] The invention relates to a test device for axle box bearings and grounding devices of rail vehicles, and more specifically, the present invention relates to a comprehensive performance test bench for axle box bearings and grounding devices. Background technique [0002] High-speed EMUs are one of the core technologies of high-speed railways. Axle box bearings and shaft end grounding devices are an important part of the EMU's driving process. In the actual operation of the EMU, the performance of the axle box bearings directly affects the operation of the EMU. If the axle box bearing is damaged, the rotation accuracy of the bearing will be lost, vibration will increase, noise and rotation resistance will be generated, and serious vehicle safety accidents will be caused. The performance of the shaft end grounding device directly affects the operation of the EMU, and the damage of the shaft end grounding device can cause fatal problems such as train power fail...
