Rail vehicle axle box bearing and earthing device reliability testing stand

Abstract

The invention relates to the rail vehicle axle box bearing and an earthing device reliability testing stand; the testing stand mainly comprises a transverse and vertical exciting apparatus, an exciting beam and support seat assembling body, a testing bearing assembling body, a motor and motor support pole assembling body; the exciting beam and support seat assembling body comprises an exciting beam support seat, a vertical exciting beam, and a testing vibration crossbeam; the motor and motor support pole assembling body is fixed on the exciting beam support seat; the testing bearing assembling body is fixed on the testing vibration crossbeam; the testing bearing assembling body and the motor and motor support pole assembling body are rotatably connected through a conveyer belt. The testing stand is simple in structure, can simulate the running speed and vibration conditions of the rail vehicle axle box bearing and earthing device on a real route, can provide a true and reliable testing environment for a stand test, thus solving the problems that the rail vehicle cannot have the rail motor coach axle box bearing and earthing device reliability test in real operation.

Description

technical field [0001] The invention relates to a test device for a rail vehicle axle box bearing and a grounding device, more specifically, the invention relates to a reliability test bench for a rail vehicle axle box bearing and a grounding device. Background technique [0002] As the main artery of the national economy, the railway is an important symbol to measure a country's infrastructure level and transportation capacity. High-speed EMUs are one of the core technologies of high-speed railways. The axle box bearings and grounding devices are important components of the EMUs. During the actual operation of the EMUs, the performance of the axle box bearings and grounding devices directly affects the operation of the EMUs. Safety, on the one hand, if the grounding device wears too fast, it will affect the conductivity of the grounding device; at the same time, the powder worn by the grounding device may follow the friction disc to the axle box bearing of the EMU, split th...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a simple structure, which can simulate the speed and vibration of the rail vehicle axle box bearing and the grounding device when running on the actual line, and can provide a real and reliable test for the rail vehicle axle box bearing and the grounding device when performing bench tests. The test environment overcomes the problem that rail vehicles cannot be tested for the reliability of EMU axle box bearings and grounding devices in actual operation, and provides a test device for rail vehicle axle box bearings and grounding devices
