Embodiment Construction

[0037] In order to make the real-time purpose and technical solution of the present invention clearer, the evaluation method and device described in the present invention will be shown more clearly and completely below in conjunction with the accompanying drawings of the present invention. The presentation is for a part of the present invention, not all of it.

[0038] attached figure 1 , The present invention proposes a device for evaluating the operating state of a locomotive bogie gearbox and a bearing run-in test bench, including three main modules: a signal acquisition module, a signal preprocessing module, and a terminal module.

[0039] The signal acquisition module is divided into three sub-modules: sound signal acquisition, vibration-temperature signal acquisition, and vibration signal acquisition, to realize the acquisition of sound, acceleration, speed, and temperature signals of bearings and gearboxes during the operation of the running-in test bench.

Abstract

The invention discloses a device and method for evaluating the operation of a locomotive bogie gear box and bearing running-in test bench. The device comprises a signal acquisition module, a signal preprocessing module and a terminal module. The device and method perform evaluation by using the modules, acquire, save, and analyze various parameters in a running-in test bench operating process in real time, establish a database, perform comprehensive analysis in combination with historical and fault data, evaluate the operating state level of running-in test bench, gearbox repair quality and bearing reliability, and whether the gear box or a bearing has faults, and give a fault alarm if so.

Description

Technical field: [0001] A device and method for evaluating the running state of a locomotive bogie gearbox and bearing running-in test bench, relating to a device and method for evaluating the state of a locomotive bogie gearbox and bearings, mainly used to evaluate the maintenance quality and quality of the gearbox after repair bearing reliability Background technique: [0002] As an important component of the locomotive operation, the locomotive bogie is required to be safe and reliable during operation. Therefore, after the locomotive bogie is repaired, it is necessary to evaluate the quality of the repair and judge whether it can be put into use. In order to test the gearbox maintenance quality and bearing reliability, the running-in test is carried out on the running-in test bench to simulate the actual running state of the bogie. [0003] For a long time, the evaluation of the running state of the bogie running-in test bench has been studied at home and abroad, but fr...
