Problems solved by technology
However, compared with contact mechanical bearings, non-contact bearings have very small bearing clearances and are more difficult to process.
[0003] For example, for non-contact radial bearings, the bearing gap between the inner ring of the bearing and the rotating shaft is very narrow, which requires the rotating shaft and the inner ring of the bearing to have high machining accuracy and assembly accuracy, otherwise it is easy to cause shaft collision. phenomenon, causing wear and damage to the bearing

The invention provides a bearing damper, a radial bearing, a thrust bearing and a rotor system. The bearing damper is used for being installed in a non-contact bearing, the bearing damper is made of ashape memory material, and the bearing damper can adjust a gap between the non-contact bearing and a rotating shaft through plastic deformation adjustment. The bearing damper is arranged in the non-contact bearing to adjust and correct the bearing gap between a stationary component and a rotating component by utilizing the plastic deformation of the bearing damper, in the manner, by arranging thebearing damper in the bearing, the requirements for bearing machining accuracy and assembly accuracy are reduced, and the stable matching accuracy between the stationary component and the rotating component of the bearing is maintained.
Description
technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing damper, a radial bearing, a thrust bearing and a rotor system. Background technique [0002] Non-contact bearings are more and more commonly used in some high-speed occasions due to their small friction coefficient and friction torque and high motion accuracy. However, compared with contact mechanical bearings, the bearing clearance of non-contact bearings is very small, and the processing difficulty is relatively high. [0003] For example, for non-contact radial bearings, the bearing gap between the inner ring of the bearing and the rotating shaft is very narrow, which requires the rotating shaft and the inner ring of the bearing to have high machining accuracy and assembly accuracy, otherwise it is easy to cause shaft collision. phenomenon, causing wear and damage to the bearing. Similarly, for non-contact thrust bearings, the bearing gap between the stator and th...
