Abstract

The utility model discloses a bearing device. The bearing device comprises a bearing seat, a bearing arranged in the bearing seat, a main shaft and a sealing ring, wherein the sealing ring comprises a steel framework and a rubber sealing piece covered on the periphery of the steel framework, two symmetrical sealing lips are arranged on the rubber sealing piece, the sealing lips are bent upwards for forming grooves, springs are arranged in the grooves, and the two sealing lips are respectively pressed on the main shaft through the two springs. According to the bearing device disclosed by the utility model, the two symmetrical sealing lips are respectively pressed on the main shaft through the two springs for realizing two-way sealing, so that the leakage of a lubricating agent can be prevented, the invasion of external pollutants can be also effectively prevented, and the sealing effect is good.

Description

A kind of bearing means

Technical field

The utility model discloses a kind of bearing means.

Background technique

The bearing means of present employing oil lubrication, prevent that by compression fit and sealing lip and main shaft interference fit between seal ring and the bearing support oiling agent from leaking, effect is bad, when vibration is big, can make sealing lip and main shaft cooperation place loosening, easily cause oiling agent to external leakage, seal form by spring crimping sealing lip is also arranged, but only adopt single sealing lip and single spring fitted seal, sealing lip is inwardly installed simultaneously, only can avoid oiling agent to leak, the intrusion of extraneous dust impurity can't be prevented, present user can't be adapted to the requirement of bearing waterproof and dustproof, leakproof.

The model utility content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of bearing means of good sealing effect is provided.

For achieving the above object, the technical solution of the utility model is: a kind of bearing means, comprise bearing support, be installed in bearing, main shaft and seal ring in the bearing support, described seal ring comprises Steel Skeleton and is covered in the rubber seal of Steel Skeleton periphery, described rubber seal is provided with the sealing lip of two symmetries, bending becomes a groove on the described sealing lip, is equiped with spring in the described groove, and described two sealing lips are pressed on the main shaft by two springs respectively.

The beneficial effects of the utility model are: respectively two sealing lips of symmetry are pressed on the main shaft by two springs, have realized two way sealed, can prevent that oiling agent from leaking, and can effectively prevent the intrusion of external pollution thing again, good sealing effect.

Description of drawings

Fig. 1 is schematic representation of the present utility model;

Fig. 2 is the schematic representation of seal ring of the present utility model.

Among the figure: bearing support 1, bearing 2, main shaft 3, seal ring 4, Steel Skeleton 41, rubber seal 42, sealing lip 421, groove 5, spring 6.

Embodiment

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

As shown in Figure 1 and Figure 2, a kind of bearing means, comprise bearing support 1, be installed in bearing 2, main shaft 3 and seal ring 4 in the bearing support 1, described seal ring 4 comprises Steel Skeleton 41 and is covered in the rubber seal 42 of Steel Skeleton 41 peripheries, described rubber seal 42 is provided with the sealing lip 421 of two symmetries, bending becomes a groove 5 on the described sealing lip 421, is equiped with spring 6 in the described groove 5, and described two sealing lips 421 are pressed on the main shaft 3 by two springs 6 respectively.

Seal ring 4 is crimped on the bearing support 1, the lip of a sealing lip 421 is inwardly installed, by the spring 6 flexible impacting forces that produce sealing lip 421 is fastened on the main shaft 3 all the time, can prevent effectively that oiling agent from leaking, the lip of another sealing lip 421 is outwards installed, by the spring 6 flexible impacting forces that produce sealing lip 421 is fastened on the main shaft 3 all the time, can effectively prevents the intrusion of environmental contaminants.

Claims
