Abstract

A composite dust cover of a bearing comprises a whole formed by a dust cover and a sealing ring that are fixed. The upper and lower end faces of the sealing ring are provided with annular grooves, the two side walls of the sealing ring are an inclined plane and a stepped inclined plane, and the outer edge of the sealing ring is attached and fixed on the edge of the inner surface of the dust cover. The composite dust cover is a composite part of the dust cover and the sealing ring. When the bearing operates at a high speed, the dust cover can dissipate heat, thus reducing the temperature rise of the bearing, and installation is conducted by pressing in the bearing. Therefore, the bearing is not likely to loosen or fall off, and good in strength. External dust and liquid can be effectively prevented from entering the inner part of the bearing, so as not to affect the service life of the bearing. In addition, the shape of the sealing ring is matched with the deep groove shaft of a deep groove ball bearing. With a plurality of contact surfaces and stress points with different shapes and positions, the sealing ring effectively prevents the escape of lubricating grease. Therefore, the lubricating and sealing effects are fine and the service life of the deep groove ball bearing is greatly prolonged.

Description

The compound dust cover of bearing

Technical field

The utility model relates to a kind of dust cover, the compound dust cover of particularly a kind of bearing that suits to use on deep groove ball bearing.

Background technique

Bearing is at work for preventing that dust and pollutant from entering its rotation of bearing internal influence, damage bearing, the lubricant grease that prevents simultaneously bearing inside again not external leakage plays lubricated, seal action, especially to allow bearing in rugged environment, can run well, avoid corroding and polluting, therefore also need outside bearing, dust cover be installed between the inner ring, be used for improving the working life of bearing.

Patent No. CN201020196253.8 " three lip band glue bearing dustproof covers ", patent No. CN201020196265.0 " lips band glue bearing dustproof cover ", it is the dust cover of different structure, shape also that patent No. CN200920041944.8 " bearing combined type dust cover " provides a kind of seal ring that has, and is used in the working life that various workplace is used to improve deep groove ball bearing.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of bearing compound dust cover, especially bearing has dust sealing and radiating and cooling effect when high speed operation, has prolonged the working life of bearing greatly, and simple in structure, easy making, be difficult for loose or dislocation, safe in utilization.

The technical scheme in the invention for solving the above technical problem is: the compound dust cover of bearing, comprise the integral body that is fixed into by dust cover and seal ring, on the upper and lower end face of described seal ring ring groove is arranged, the two side is inclined-plane and ladder inclined-plane, and the outward edge of seal ring is close on the inner surface edge that is fixed on dust cover.

Compared with prior art, advantage of the present utility model is: the compound dust cover of bearing, composite members for dust cover and seal ring, dust cover can dispel the heat when the bearing high speed operation, reduce the temperature rise of bearing, and be pressed in the bearing and install, so it is difficult for loosening, come off, intensity is good, can prevent effectively that external dust and liquid from entering the working life of bearing internal influence bearing, the zanjon shape of the shape of seal ring and deep groove ball bearing is complementary in addition, and the surface of contact and the force bearing point of a plurality of difformities and position arranged, and effectively prevents leaking of lubricant grease, therefore lubricated, good sealing effect, the working life of having improved deep groove ball bearing greatly.

Description of drawings

Fig. 1, structural representation of the present utility model (enlarged view).

Fig. 2, user mode reference drawing of the present utility model.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Dust cover 1 is made into by metallic material, and the centre has through hole, edge that the crotch 1-1 of circular arc is arranged.

Seal ring 2 is made into ring by rubber material, and upper and lower end face has the depth, the ring groove 2-2 of going up in different size and following ring groove 2-3.

The volume of following ring groove 2-3 is convenient to the storage of lubricant grease greater than last ring groove 2-2.

The two side is inclined-plane 2-4 and ladder inclined-plane 2-1, and the compacting of being convenient to seal ring is installed, and the area of contact of the upper and lower end face on upper and lower ring groove 2-2,2-3 limit and dustproof groove 5 inwalls on the bearing inner race 6 is big, and is close to surface of contact and makes sealing effect better.

Seal ring 2 hot pressing are fixed on becomes holistic composite members on the dust cover 1, as shown in Figure 1.

With mould above-mentioned composite members is pressed in the deep groove ball bearing, and make seal ring 2 parts on the composite members be bumped into dustproof groove 5 internal fixation on the bearing inner race 6, dust cover 1 part is pressed into dustproof groove 4 internal fixation on the bearing outer ring 3, installs the back and just can use, as shown in Figure 2.

Claims

1. compound dust cover of bearing, comprise the integral body that is fixed into by dust cover (1) and seal ring (2), it is characterized in that on the upper and lower end face of described seal ring (2) ring groove being arranged, the two side is inclined-plane (2-4) and ladder inclined-plane (2-1), and the outward edge of seal ring (2) is close on the inner surface edge that is fixed on dust cover (1).

2. the compound dust cover of bearing according to claim 1 is characterized in that there is last ring groove (2-2) upper-end surface of described seal ring (2), and there is following ring groove (2-3) lower end surface, and the volume of following ring groove (2-3) is greater than last ring groove (2-2).
