Abstract

The utility model relates to a bearing cage with a claw. The bearing cage comprises an upper cover and a lower cover. The upper cover and the lower cover are both composed of planes and ball pockets. The plane of the lower cover extends outwards to form the claw, one side of the claw contacting the upper cover is a polished round face, and a V-shaped bent port is arranged at the connection position between the claw and the lower cover. The bearing cage with the claw has the advantages that by means of the polished round face arranged at the upper portion of the claw, the claw coupling is enhanced; a hard layer made of high-strength abrasion-resistant materials is added on ball pocket faces of the bearing cage so as to improve impact resistance and tension resistance of the bearing cage; the service life and productivity of bearings are improved; production cost is saved; overall performance of bearing is improved; and the bearing cage is simple in manufacture process, reliable to use, obvious in effect and good in popularization and application value.

Description

A kind of bearing cage with pawl

Technical field

The utility model relates to the bearing cage technical field, especially relates to a kind of bearing cage with pawl.

Background technique

Bearing is mechanical industry common part; It basic composition is inside and outside lasso, steel ball and retainer; Between inner ring and outer ring, retainer also evenly distributes with the circumference that keeps above-mentioned steel ball can center on lasso between inner ring and outer ring steel ball as the rolling supporting element.At present; The miniature curved pawl wave-shaped retainer of ordinary construction because its original structure can not make its ball pocket fabric width strengthen, is restricted the female surface of steel ball; Be unfavorable for controlling vibration and the different sound that steel ball is produced the retainer bump, finished product is difficult for cleaning and causes harmful effects such as hindering ball.

Therefore, a kind of long service life, cost is low, and the appearance of nonabradable bearing cage is necessary.

The model utility content

The utility model is to provide a kind of long service life for solving the problems of the technologies described above, and cost is low, nonabradable bearing cage.

The technical problem that the utility model solved adopts following technological scheme to realize:

A kind of bearing cage with pawl comprises loam cake, lower cover, and said loam cake and lower cover are formed by plane and ball pocket face, on the plane of said lower cover, are outward extended with pawl, and wherein, the top of the one side that said pawl contacts with said loam cake is the polishing disc; Said pawl and said lower cover joint are provided with V-type bending mouth.

Preferably, on the said ball pocket face of said loam cake and lower cover, also be provided with hard layer, to strengthen its wear resistance.

Further, the thickness of said hard layer is 0.01-0.3mm.

The beneficial effect that the utlity model has is: 1, through the top to pawl the polishing disc is set, to strengthen its closing property of pawl;

2, through on the ball pocket face of retainer, increasing the hard layer of high-strength abrasion-proof material, improved the anti-impact force and the stretching resistance of bearing cage;

3, improved the working life and the productivity of bearing, practiced thrift cost of production, the combination property of the bearing of raising;

4, this bearing cage preparation process is simple, uses reliably, and effect is obvious, has the excellent popularization using value.

Fig. 2 is that A-A among Fig. 1 is to sectional drawing;

Fig. 3 is the utility model: a kind of structural representation of pawl of the bearing cage with pawl;

Wherein: 1-loam cake, 2-lower cover, 11-plane, 12-ball pocket face, 13-pawl, 14-hard layer, 15-V type bending mouth.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.

With reference to shown in Figure 1, a kind of bearing cage with pawl comprises loam cake 1, lower cover 2; Said loam cake 1 is formed by plane 11 and ball pocket face 12 with lower cover 2; On the plane 11 of said lower cover 2, be outward extended with pawl 13, wherein, the top of the one side that said pawl 13 contacts with said loam cake 1 is the polishing disc; Said pawl 13 is provided with V-type bending mouth 15 with said lower cover 2 joints.

Preferably, on the ball pocket face 12 of loam cake 1 and lower cover 2, also be provided with the hard layer 14 that thickness is 0.01-0.3mm, to strengthen its wear resistance.

The utility model is provided with the polishing disc through the top to pawl, to strengthen its closing property of pawl; Through on the ball pocket face of retainer, increasing the hard layer of high-strength abrasion-proof material, improved the anti-impact force and the stretching resistance of bearing cage; Improved the working life and the productivity of bearing, practiced thrift cost of production, the combination property of the bearing of raising; This bearing cage preparation process is simple, uses reliably, and effect is obvious, has the excellent popularization using value.

More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.

Claims
