Abstract

The invention discloses a bearing testing device of a locomotive traction motor. The device comprises a test shafting part, a lathe bed, a platform, a power-driven system, a dynamic loading system, a lubrication system, an induced airflow simulation system and a monitoring system. A proportional pressure reducing valve is adopted to apply constant or pulsative radial load and alternating axial load to a test bearing; a high-low temperature box is adopted to heat or cool a test shafting; a large centrifugal fan is adopted to simulate an ultra-high air speed; a test collecting system is adopted to test and collect test parameters such as temperature, pressure, vibration, a rotational speed, an air speed and the like; and a tester microcomputer performs automatic control, monitoring and recording, and has functions of automatic protection, overheat alarm, abnormal vibration alarm and the like.

Description

technical field [0001] The invention relates to a rolling bearing test bench, in particular to a test device for a traction motor bearing of a locomotive. Background technique [0002] Test is an indispensable and important verification process in the bearing design and manufacturing process, which can effectively control the quality risk within the production enterprise. Bearing tests include life test, simulation test, performance test, component test, strengthening test, design verification test, material test, etc. Among them, the performance test evaluates a certain special performance of the bearing, such as high and low temperature test, ultra-high wind speed test, etc. The design verification test is based on the data of the bearing test, such as temperature rise, vibration and noise, to propose design improvement suggestions. [0003] The locomotive bearing is one of the key components of the locomotive, and the safety of the bearing is related to the safe operati...
