Problems solved by technology

[0003] The first object of the present invention is to provide a two-way sealed suspension bearing assembly with good sealing effect, which solves the problem that the outer layer of the existing suspension bearing is prone to poor sealing
[0004] The second purpose of the present invention is to further provide a two-way sealed suspension bearing assembly with adjustable sealing effect and compensation after wear, which solves the problem that the existing sealing method cannot be compensated after wear

Embodiment 1

[0021] Embodiment one, see figure 1 , a two-way sealed bearing assembly for suspension, comprising an annular upper cover, a bearing body and an annular lower cover 1 sequentially arranged from top to bottom. The lower cover is provided with an annular groove 2 extending circumferentially along the lower cover. The axis of the bearing extends in the vertical direction. The bearing body includes an inner ring 3, an outer ring 4 sheathed on the inner ring and rolling balls 5 located between the inner ring and the outer ring. The lower end of the outer ring is provided with an inner flange 6 supported on the lower side of the rolling ball. The upper end of the inner ring is provided with an outer flange 7 pressed against the upper side of the rolling ball. The rolling balls are connected together in line contact with both the inner and outer rings. The inner ring and the outer ring simultaneously clamp the rolling ball along the radial direction and the axial direction of the...

Embodiment 2

[0022] Embodiment two, the difference with embodiment one is:

[0023] One end of the first outer sealing ring and the second outer sealing ring are integrally formed together and sealed and fixed with the inner cover.

Embodiment 3

[0024] Embodiment three, the difference with embodiment one and two is:

[0025] see image 3 , the outer cover is provided with a connecting hole 19 communicating with the sealed cavity. A valve 20 is connected in the connection hole. A ring-shaped guide elastic piece 21 is provided on a side of the first outer sealing ring facing the second outer sealing ring. The axial ends of the guide shrapnel are sealingly connected with the axial ends of the first outer sealing ring. An escape cavity 22 is formed between the first outer sealing ring and the guide elastic piece. The section of the guide shrapnel is an arc arched towards the inside of the sealing chamber. When in use, the air valve is used to inflate and deflate to change the sealing effect and produce compensation after wear and tear. image 3 in figure 2 The above changes are made on the basis of figure 1 It is also possible to make the above changes on the basis of .

Abstract

The invention relates to a bidirectional-sealing bearing assembly for suspension. The bidirectional-sealing bearing assembly comprises an annular upper cover, a bearing body, an annular lower cover, an inner side sealing ring, a first outer side sealing ring and a second outer side sealing ring which are sequentially arranged from top to bottom. The upper cover comprises an end wall, an annular inner side wall and an annular outer side wall. An annular groove is defined by the end wall, the annular inner side wall and the annular outer side wall. The lower cover is arranged in the annular groove in a penetrating manner. The lower surface of the end wall and the lower cover are connected together in a sealed manner through the first outer side sealing ring. The inner circumferential face ofthe annular outer side wall and the lower cover are connected together in a sealed manner through the second outer side sealing ring. The annular inner side wall and the lower cover are connected together in a sealed manner through the inner side sealing ring. A bearing is located between the inner side sealing ring and the first outer side sealing ring. The bidirectional-sealing bearing assemblyhas the advantage of being good in sealing effect, and the problem that the poor sealing phenomenon is likely to happen to an outer layer of a suspension bearing in the prior art is solved.

Description

technical field [0001] The invention relates to a bearing, in particular to a two-way sealed suspension bearing assembly. Background technique [0002] Bearing ("Bearing", Japanese called "shaft receiver") is a component that fixes and reduces the load friction coefficient during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. One of the bearings is used to suspend and realize the rotation of the suspended object. This type of bearing is called a suspension bearing. The local structure of the suspension bearing includes an upper cover, a bearing body and a lower c...
