Description

technical field

[0001] The invention belongs to the field of bearing testing, and in particular relates to a loading testing platform for multi-model bearings in a wide temperature range. Background technique

[0002] Bearings are the core components of many mechanical rotating equipment, involving aerospace, deep-sea ships, petrochemical and many other fields. The dynamic characteristics and life of bearings directly determine the working efficiency and machining accuracy of mechanical equipment. In order to further analyze the failure and mechanism of the bearing under different working conditions and improve the life of the bearing, the bearing test platform has been widely used. At present, the traditional bearing test platform is rarely able to meet the bearing loading test under extreme temperature. The ambient temperature can only be increased or decreased, and it is difficult to simulate the corrosion-resistant environment in a wide temperature range under extreme co...
