Abstract

The utility model relates to a bearing seal check ring, which belongs to the technical field of machinery, and solves the problems that the conventional bearing seal check ring has poor air-tightness and can not satisfactorily play the functions of limiting and guiding on rollers. The bearing seal check ring comprises a ring-shaped framework, wherein sealing bodies are fixedly connected with the inner side surface and the upper surface of the framework; a shoulder pad is arranged on the side surface of the outer edge of the framework; a plurality of grooves are formed on the shoulder pad; the grooves divide the shoulder pad into a plurality of divided-sections of shoulder pad; and every divided-section of shoulder pad can be bent to the upper surface side and connected in a seal ring groove in a sealing way during the sealed installation. The utility model has the advantages that the bearing seal check ring has excellent air-tightness and can satisfactorily limit and guide the rollers.

Description

The bearing seal back-up ring

Technical field

The utility model belongs to field of mechanical technique, refers in particular to a kind of bearing seal back-up ring.

Background technique

At present, existing bearing sealed ring comprises skeleton and the seal that is connected on the skeleton, generally be installed in the o-ring groove of bearing outer ring inboard by the elastic sealed body on the external diameter outer, only be to play the dust sealing effect, axial locking power is very little, can not be as the retaining of roller bearing or clutch roller along guiding function; In addition, but existing back-up ring only play axial limiting and guiding function and do not have sealing function.

Summary of the invention

The purpose of this utility model provides a kind of good airproof performance and can play the bearing seal back-up ring that roller is carried out spacing leading role again.

The purpose of this utility model is achieved in that the bearing seal back-up ring, comprise the skeleton that is ring, be fixed with seal on the inner side surface of skeleton and the upper surface, it is characterized in that: the outer edge side mask of described skeleton has shoulder protector, have several grooves on the shoulder protector, described groove is separated into several segmentation shoulder protectors with shoulder protector, and when sealing was installed, each segmentation shoulder protector can be sealedly connected in the o-ring groove toward that side direction bending of upper surface.

Have retaining edge, upwardly extending location, that side of past skeleton upper surface on the inner side surface of above-mentioned skeleton, the location retaining is along being embedded in seal.

Above-mentioned skeleton is formed by spring steel material or carbon constructional quality steel material.

Above-mentioned seal is made by rubber material.

Above-mentioned groove is a del or trapezoidal.

The outstanding compared to existing technology advantage of the utility model is:

1, skeleton of the present utility model and seal become integral body for being fixed together, and its skeleton is made by spring steel material, the intensity height, good rigidly, make it possible to well roller be carried out spacing leading role, its seal is that rubber material is made, corrosion-resistant and good airproof performance;

2, have shoulder protector on its skeleton of the utility model, have groove on the shoulder protector, when mounted segmentation shoulder protector bending is sealedly connected in the o-ring groove, the punching press installation process is not yielding, the axial/radial accurate positioning, firmly and sealing high;

3, the utility model long service life, simple in structure and be convenient to install.

Embodiment

The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-4:

The bearing seal back-up ring, comprise the skeleton 1 that is ring, be fixed with seal 5 on the inner side surface of skeleton 1 and the upper surface, it is characterized in that: the outer edge side mask of described skeleton 1 has shoulder protector 2, have several grooves 3 on the shoulder protector 2, described groove 3 is separated into several segmentation shoulder protectors with shoulder protector 2, and when sealing was installed, each segmentation shoulder protector can be sealedly connected in the o-ring groove toward that side direction bending of upper surface.

Have upwardly extending location, that side of past skeleton 1 upper surface retaining on the inner side surface of above-mentioned skeleton 1 along 4, the location retaining is embedded in seal 5 along 4.

Above-mentioned skeleton 1 is made by spring steel material.

Above-mentioned seal 5 is made by rubber material.

Above-mentioned groove 3 is a del.

The groove 3 of del provides the space for the bending of each segmentation shoulder protector 2, during installation, Sealing shield ring is installed between bearing outer ring 6 and the bearing inner race 7, each segmentation shoulder protector 2 bending is sealedly connected in the o-ring groove 3, improve sealing, 1 pair of roller of skeleton of being made by hard spring steel has good spacing leading role simultaneously.

Skeleton 1 in the present embodiment can also be formed by the carbon constructional quality steel material, the groove 3 in the present embodiment can also for or trapezoidal.

The foregoing description is preferred embodiment of the present utility model only, is not to limit protection domain of the present utility model according to this, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.

Claims
