Abstract

The invention relates to a sealed bearing comprehensive performance simulation testing machine and belongs to the field of bearing performance testing. The sealed bearing comprehensive performance simulation testing machine comprises a bearing test unit, a driving unit, a loading unit, an environment simulation system and a control system. The bearing test unit is arranged in the environment box of the environment simulation system, is arranged on the same plate with the driving unit, and is connected with the loading unit. The driving unit is arranged on the left side of the environment box. The loading unit comprises a radial loading mechanism and an axial loading mechanism. The environment simulation system comprises the environment box, a high-temperature simulation unit, a low-temperature simulation unit, a humidity simulation unit and a dust simulation unit. The control system is connected with the driving unit, the loading unit, and the environment simulation system, and controls test rotating speed, test load, test ambient temperature, and test ambient humidity, and test environment dust concentration. The sealed bearing comprehensive performance simulation testing machine is reasonable in structure, complete in simulated working conditions, good in test results, and easy to operate, and satisfies the evaluation demands of sealed bearing comprehensive performance.

Description

technical field [0001] The present invention relates to the field of bearing performance testing, in particular to a simulation test system for comprehensive performance evaluation of sealed bearings, including bearing high-speed performance, high and low temperature resistance performance, heat and humidity resistance performance and dustproof performance, etc., which are closely related to the service life of the bearing dynamic performance. Background technique [0002] At present, 80% of the rolling bearings are grease lubricated, and more than 80% of the grease lubricated bearings are sealed bearings. Due to the diversity of bearing application conditions and application environments, resulting in the diversity of its performance requirements, such as fatigue resistance in heavy-duty application conditions, high-speed performance in high-speed application conditions, etc., but these performances are closely related to the application environment. Take the high-speed pe...
