Embodiment 1

[0024] Embodiment 1 of bearing support 10 of the present application, such as figure 1 As shown, the bearing support 10 includes an upper housing 11 , a lower housing 12 , a bearing 13 accommodated between the upper housing 11 and the lower housing 12 , a radial seal 14 and an axial seal 15 .

[0025] Specifically, both the upper casing 11 and the lower casing 12 are generally in the shape of a ring disk, and the two can adopt the buckle structure as shown in the figure to realize interlocking, and form an accommodating chamber for the bearing 13, and the bearing 13 is placed in the Specifically, the application does not specifically limit the type of the bearing 13 in the accommodating cavity, and it can be flexibly configured according to specific application environments or requirements, such as deep groove ball bearings or angular contact bearings, which are shown in the figure as deep groove ball bearings.

[0026] In order to ensure the sealing of the bearing and prevent...

Embodiment 2

[0039] Embodiment 2 of the bearing support 20 of the present application has basically the same structure as the bearing support 10, such as Figure 5 As shown, the bearing support 20 includes an upper shell 21 , a lower shell 22 , a bearing 23 accommodated between the upper shell 21 and the lower shell 22 , a radial seal 24 and an axial seal 25 . Compared with the bearing support 10 in Embodiment 1, the bearing support 20 has the following differences:

[0040] The radial outer side of the lower convex ring 214 of the upper housing 21 forms a third side wall 2142, the surface of the third side wall 2142 forms a certain angle with the rotation axis of the bearing 23, and the radial seal 24 There is also a third sealing lip 245 protruding from the radial seal body 241. The second radial sealing lip 244 and the third sealing lip 245 are respectively located on both radial sides of the lower convex ring 214. The third sealing lip An axial seal is formed between 245 and the third...

Abstract

The invention relates to a bearing support. The bearing support comprises an upper housing, a lower housing, a bearing accommodated between the upper housing and the lower housing and at least one axial sealing piece, wherein the upper housing comprises a side wall and a top wall, which are located on the same side of the bearing in the radial direction; the axial sealing piece comprises an axial sealing piece body, a fixing part, a radial sealing lip and a first axial sealing lip; the fixing part, the radial sealing lip and the first axial sealing lip protrude out of the axial sealing piece body; the fixing part is used for fixing the axial sealing piece to the upper housing or the lower housing; the radial sealing lip and the side wall realize radial sealing; the first axial sealing lip and the top wall realize axial sealing; and the radial sealing lip and the first axial sealing lip are located on the same side of the axial sealing piece body in the radial direction. The bearing support provided by the invention adopts the axial sealing piece and can well avoid the invasion of external foreign matters caused by radial dislocation of the upper housing and the lower housing, so that the sealing property of the bearing support is improved.

Description

technical field [0001] The application relates to the field of machinery, in particular to a bearing support. Background technique [0002] Suspension strut is a device for attenuating vibration in a vehicle, connecting the body and chassis to provide smoothness and comfort for the vehicle. Generally, a suspension strut includes a coil spring, a shock absorber, a shock absorber, and a support bearing. The support bearing in the suspension strut needs to bear the weight and impact of the vehicle body, and provide steering function. Due to the requirements of the suspension structure and installation, the support bearing is generally exposed outside, so not only the support bearing needs to be able to bear the weight of the vehicle body, potholes and road surface Shock, steering and braking shocks also need to be able to resist external foreign matter, such as dust, mud or muddy water, that is, good sealing performance is required. [0003] The Chinese utility model patent C...
