Abstract

The invention relates to a test device of a wheel pair axle box bearing of an axle gearbox, belonging to the technical field of test devices of axle box bearings. The test device of the wheel pair axle box bearing of the axle gearbox comprises a tooling fixing mechanism, a drive mechanism and a control mechanism, wherein the tooling fixing mechanism comprises a platform and two test toolings installed on the platform, the test toolings and the platform are detachably connected through a tooling fixing base, the drive mechanism comprises a motor installation base and an inverter motor and a motor regulation base that are installed on the motor installation base, the motor regulation base can drive the inverter motor to move along the length direction of the motor installation base relativeto the motor installation base, and the control mechanism comprises a strong current cabinet and an operation table that are installed at two sides of the platform. The test device of the wheel pair axle box bearing of the axle gearbox is easy to operate, can be controlled accurately, has high automation degree, and can set a corresponding test process according to test needs so as to simulate actual working conditions, thereby being an efficient test manner for detection of performance of axle gearboxes

Description

technical field [0001] The invention relates to the technical field of an axle box bearing test device, in particular to an axle box bearing test device for a wheel set of an axle gearbox. Background technique [0002] Large-scale railway maintenance machinery mainly includes DC-32, DCL-32, CDC-16, DWL-48, WD-320 and other types of tamping and stabilizing device vehicles. Among them, the axle gearbox is used as the power transmission mechanism of the work vehicle, and the axle box bearing test needs to be carried out on it before leaving the factory. According to the test information such as the operating noise of the gearbox, the temperature of the box and the bearing, it is judged whether the performance of the axle gearbox is up to standard. [0003] When the axle box bearing test is carried out on the existing axle gearbox, since the axle box components are installed at both ends of the axle, the loading is arranged at the driving end. Affected by the appearance and siz...
