Embodiment Construction

[0044] The present invention is described in detail below in conjunction with accompanying drawing:

[0045] The invention provides a U-shaped bench-top transmission system (back-to-back) reliability test bench for a transmission system of an EMU to meet the requirements for detecting reliability parameters of axle box bearings of the transmission system of an EMU under various operating conditions. The test bench adopts a reasonable load simulation system to accurately simulate the working state and vibration of the gear box of the EMU during actual operation, ensuring the correctness and authenticity of the gear box structure of the EMU under the reliability parameter test. Under the structure of the narrow U-shaped platform assembly B, this test bench can simulate the real-time state of the axle box bearing when the gearbox is tilted at an angle. Causes of failure and specific technical parameters. When simulating the frequent changes of the inner rail and the outer rail o...

Abstract

The invention discloses a test bench for the reliability of a U-shaped desk-type transmission system of a gear box of a motor train unit, and aims at solving a problem that a reliability test of a bearing of an axle box of a transmission system of the motor train unit cannot be carried out. The test bench comprises a gear box test vibration shaft assembly, a narrow U-shaped platform assembly, an arc-shaped seat assembly, a front cross-shaped guide rail supporting seat, and a rear cross-shaped guide rail supporting seat. The narrow U-shaped platform assembly is disposed on a foundation. A left arc-shaped seat assembly and a right arc-shaped seat assembly of the arc-shaped seat assembly are disposed on the foundation at two sides of the narrow U-shaped platform assembly. A U-shaped upper angle platform of the gear box test vibration shaft assembly is disposed on a narrow U-shaped platform of the narrow U-shaped platform assembly and locked. A left motor assembly and a right motor assembly of the gear box test vibration shaft assembly are sequentially connected with an inner side of the arc-shaped seat assembly. One end of the front cross-shaped guide rail supporting seat and one end of the rear cross-shaped guide rail supporting seat are disposed at the front and rear ends of a right platform. The other end of the front cross-shaped guide rail supporting seat and the other end of the rear cross-shaped guide rail supporting seat are disposed at the front and rear ends of the narrow U-shaped platform.

Description

technical field [0001] The invention relates to a test device for detecting and testing parameters of a transmission system of a rail vehicle, more specifically, the invention relates to a U-shaped desktop transmission system reliability test bench for a gear box of an EMU. Background technique [0002] At present, my country's EMU technology is developing rapidly. The maximum speed of EMUs already in operation has reached 380km / h, and the maximum speed of EMUs under development is close to 500km / h. With the increase of the running speed of the EMU and the intensification of the vehicle axle load, the vibration between the EMU and the track is intensified, the running stability of the EMU is reduced, and the safety and running stability of the EMU have become increasingly prominent. At the same time, with the on-line operation of a large number of EMUs, the maintenance work of the EMUs at all levels has also been carried out. Among them, the maintenance of the axle box beari...
