Problems solved by technology

Large-scale bearing testing machine is the key equipment for life test and performance test of large-scale bearings. However, at present, the number of large-scale bearing testing machines is small, and they are large in size, high in cost and relatively single in function, which cannot meet people's increasingly stringent requirements for large-scale bearings. Test requirements

Abstract

The invention belongs to the technical field of bearing tests, in particular to a large bearing testing machine. The large bearing test machine is characterized by consisting of a test unit, a loadingunit, a drive unit, a control unit, a hydraulic power unit and a workbench. The loading unit, the drive unit and the control unit are arranged on the workbench, the test unit is arranged on the loading unit, the hydraulic power unit is arranged behind the workbench and connected with the loading unit, the control unit is matched with the test unit, the loading unit, the drive unit, and the hydraulic power unit respectively. The test unit is used for receiving a large bearing for test, the loading unit applies radial load, axial load and capsizing moment to the test bearing, the drive unit drives the test bearing to rotate at a specified rotation speed and torque, and the control unit controls electrical operation and protection, monitors test operation, analyzes test procedures and results, and give feedbacks at proper time.

Description

technical field [0001] The invention belongs to the technical field of bearing testing, in particular to a large bearing testing machine. Background technique [0002] Large bearings with an outer diameter of Φ400mm to 1000mm are widely used in wind power generation, railway vehicles, metallurgical mines, petroleum machinery, construction machinery and other industries, and the working environment is harsh, so high precision, long life and high reliability are required. Fatigue life and reliability of bearings are the most important performance indicators of bearings, but because there are too many factors affecting fatigue life and the theory of bearing fatigue life still needs to be perfected, life testing is the only effective way at present. Bearing friction torque is also a key performance indicator of bearings. Many working conditions require testing of performance indicators such as maximum friction torque and average friction torque of bearings. Large-scale bearing ...
