Embodiment Construction

[0075] Below in conjunction with accompanying drawing of description, the specific embodiment of the present invention is described further:

[0076] The invention provides a high-speed rail vehicle axle box bearing comprehensive performance and axle end grounding device wear test bench to meet the needs of simultaneously testing the rail vehicle axle box bearing comprehensive performance and the axle end grounding device wear. The test bench adopts a reasonable excitation loading layout scheme, which avoids the danger and loss caused by the destructive test on the actual running vehicle, and can simulate the vibration conditions of three degrees of freedom and three degrees of freedom coupling respectively. That is to simulate the vibration state of the actual operation of the rail vehicle to the greatest extent, thus ensuring the correctness and authenticity of the test data and test results. The test bench can meet the needs of the research and development and testing of ra...

Abstract

The invention discloses a rail vehicle axle box bearing comprehensive performance and shaft end grounding device wear test bench which is composed of a test shaft assembly and bearing seat assembly body, and a longitudinal stabilizing mechanism, transverse vibration loading mechanisms, a fan set, test bearing spring lifting mechanisms and vertical vibration loading mechanisms which are fixed on a cast iron T-slot platform. The transverse vibration loading mechanism is coaxially connected with a bearing seat transverse force transfer frame. The longitudinal stabilizing mechanism is fixedly connected with the upper surfaces of slave bearing-bearing seat assemblies. The fan set is installed above test bearing-bearing seat assemblies. The vertical vibration loading mechanisms are connected with the bottom surfaces of the slave bearing-bearing seat assemblies. The tops of the bearings of the test bearing spring lifting mechanisms are in contact connection with the bottom surfaces of the test bearing-bearing seat assemblies. With the test bench, the comprehensive performance of an axle box bearing and the wear of a shaft end grounding device can be tested simultaneously, the test efficiency is improved greatly, and the test resources are saved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle testing, in particular to a test bench for the comprehensive performance of a rail vehicle axle box bearing and the wear of an axle end grounding device, which is suitable for testing the comprehensive performance of a high-speed rail vehicle axle box bearing and the wear of an axle end grounding device. Background technique [0002] In recent years, with the vigorous development of my country's high-speed rail industry, breakthroughs have been made in various technologies related to high-speed rail trains. Among them, bearings are important running support components of rail vehicles. The working environment is harsh, and the load force changes frequently. It is very easy to suffer fatigue damage under high-speed driving and severe vibration. The condition of the bearing directly affects the safety of train operation. As an important part of the EMU grounding system, the grounding device pla...
