Heat conduction piece, bearing composite supporting cooling structure and vacuum pump

Abstract

The invention provides a heat conduction piece, a bearing composite supporting cooling structure and a vacuum pump. The bearing composite supporting cooling structure comprises a rotating shaft, a bearing, a bearing end cover, a flexible gasket and the heat conduction piece, the flexible gasket and the heat conduction piece are both located between the bearing and the bearing end cover, one side of the flexible gasket is in abut joint with the bearing end cover or the bearing, the other side of the flexible gasket is in abut joint with the heat conduction piece, the heat conduction piece comprises a body, the middle of the body is provided with a first through hole, the body is made of the flexible heat conduction material, the heat conduction piece is arranged between the bearing and thebearing end cover, the heat conduction piece can be opposite to the end face of the bearing, the heat of the bearing is emitted out, the heat conduction piece can be directly in abut joint with the bearing and the bearing end cover, the elastic energy of the heat conduction piece is used for relieving the vibration between the bearing and the bearing end cover, the good buffer damping effect is achieved, the heat conduction piece can be further achieve the heat conduction at the same time, the service life of the bearing can be effectively prolonged, the whole structure is ingenious, and mounting is convenient.

Description

technical field [0001] The invention relates to the technical field of a pump bearing heat dissipation structure, in particular to a heat conduction sheet, a bearing compound support heat dissipation structure and a vacuum pump. Background technique [0002] With the development of science and technology, users' demand for high-speed bearings is becoming more and more common. Scenes where high-speed bearings are used in harsh working conditions occur from time to time, but when the existing high-speed bearings are used in some special working conditions, such as Under bumpy, vibration, high-speed, vacuum and other working conditions, there will be big problems in the service life and heat dissipation of the bearing. Especially in fields such as molecular pumps or vacuum pumps that require continuous high-speed operation, there are high requirements for bearing life and heat dissipation. [0003] In the Chinese patent application with the publication number CN206211765U, a b...
