Embodiment 1

[0031] Please also refer to figure 1 and figure 2 , the heat conducting sheet 4 provided by the present invention will now be described. The heat conducting sheet 4 is used to be arranged between the bearing 1 and the bearing end cover 2 , and includes a body 41 , and the opposite sides of the body 41 abut against the bearing 1 and the bearing end cover 2 respectively.

[0032] Compared with the prior art, the heat conduction sheet 4 provided by the present invention is arranged between the bearing 1 and the bearing end cover 2 and sleeved on the rotating shaft 3. The heat conduction sheet 4 is opposite to the upper end surface of the bearing 1. Due to the bearing 1 The wall thickness of the upper and lower end surfaces is thinner or there is no sealed fixed wall, so the heat dissipation speed of the upper and lower end surfaces of the bearing 1 is faster. At this time, the heat conduction sheet 4 is covered on the upper end surface of the bearing 1 and can contact the condu...

Embodiment 2

[0040] see figure 2 , the present invention also provides a bearing composite support heat dissipation structure, the bearing composite support heat dissipation structure includes a rotating shaft 3, a bearing 1 sleeved on the rotating shaft 3, a bearing end cover 2, a flexible washer 5 and as in Example 1 The heat conducting sheet 4, the rotating shaft 3 passes through the first through hole 42, the flexible gasket 5 and the heat conducting sheet 4 are both located between the bearing 1 and the bearing end cover 2, the One side of the flexible washer 5 is in contact with the bearing end cover 2 , and the other side is in contact with the heat conducting sheet 4 .

[0041] The bearing composite supporting heat dissipation structure provided by the present invention combines the flexible washer 5 with the heat conducting sheet 4, the flexible washer 5 can directly contact the heat conducting sheet 4 and the bearing end cover 2, and the flexible washer 5 and the bearing 1 pass ...

Embodiment 3

[0050] see image 3 and Figure 4 , the present invention also provides a vacuum pump, the vacuum pump includes the bearing composite supporting heat dissipation structure as described in Embodiment 2.

[0051] Compared with the prior art, the vacuum pump provided by the present invention adopts the composite supporting heat dissipation structure of the bearing in Embodiment 2, and utilizes the elastic energy of the flexible gasket 5 and the heat conducting sheet 4 to ease the tension between the bearing 1 and the bearing end cover 2 Vibration, the heat conduction sheet 4 can also realize contact heat dissipation at the same time, so that the bearing structure in the vacuum environment in the vacuum pump can still achieve a better heat dissipation effect, which can effectively prolong the service life of the bearing 1. The entire structure is compact and will not affect other parts of the vacuum pump. The installation and selection of components are highly replaceable, prolon...

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...
