Full-life attenuation simulation experiment device for traction motor bearing of high-speed train

Abstract

The invention relates to a bearing lifetime simulation experiment device, in particular to a full-life attenuation simulation experiment device for a traction motor bearing of a high-speed train. By the full-life attenuation simulation experiment device, the problem that the traction motor bearing of the high-speed train lacks of the simulation experiment device is solved. The typical structure configuration of the traction motor bearing is simulated, a sealing lubrication structure is designed, a load is applied to the bearing by a loading oil cylinder, an experiment load is used for equallyloading according to load borne by the traction motor bearing running under a rated working condition, grease lubrication is employed, vibration and temperature signal acquisition, recording and processing of the experiment bearing are completed by a data acquisition system, and monitoring and control of the experiment process are achieved by matching of a computer system. The lifetime simulationexperiment device which is adjustable in radial and axial load, has grease lubrication and can be used for simulating structure configuration of the traction motor bearing of the high-speed train is given out, so that the experiment bearing structure, the sealing lubrication structure and a product are maintained consistency, and the truth and the accuracy of the acquired life attenuation rule ofthe traction motor bearing are ensured.

Description

technical field [0001] The invention relates to a bearing life simulation test device, in particular to a high-speed EMU traction motor bearing full life decay simulation test device. Background technique [0002] In the operation of high-speed railway EMUs, the traction motor bearing is a key component for safe operation, and it is also one of the most easily damaged components. However, my country's bearing industry lacks corresponding key experimental technologies and special equipment, and seldom conducts research on the full-life decline test of high-speed railway traction motor bearings, and fails to establish a bearing full-life decline curve and obtain the law of decline. [0003] Most of the current rolling bearing life testing machines are only suitable for the durability life of the bearing itself. Most of the bearings of the same type are distributed on both sides of the testing machine for life testing, and the lubrication is carried out by means of circulating ...
