Abstract
The utility model relates to a deep groove ball bearing retainer and a bearing applying same, wherein the retainer comprises a frame I and a frame II which are butted with each other and composed of ball bags and planes connecting the ball bags into a ring; at least three planes of the frame I are provided with preiections; the corresponding planes of the frame II are provided with positioning holes corresponding to the preiections; and the preiections pass through the positioning holes to be welded with the frame II. The bearing retainer can realize the firm welding between the frame I and the frame II, avoid rivet connection, reduce production cost and noise and avoid the radial moving of the frame I and/or the frame II and the rivet drop-off.
Description
Technical field:
The utility model relates to a kind of retainer, relate in particular to a kind of deep groove ball bearing retainer and use the bearing of this retainer.
Background technique:
In the now general deep groove ball bearing retainer, two support bodys of butt joint are fixedly connected by rivet mutually.There is following shortcoming in this connecting structure: 1, when rivet and plane out of plumb, support body can take place radially to move about, and rivet is come off; 2, be easy to generate the slit between two support bodys, can produce noise in the course of the work; 3, the use of rivet has strengthened cost of production.Existing in prior technology deficiency that Here it is.
The model utility content:
The technical problems to be solved in the utility model is exactly at the existing in prior technology deficiency, and provide a kind of deep groove ball bearing retainer that two support bodys can firmly dock and bearing of using this retainer of making, this retainer can be avoided radially moving about of support body and rivet to come off and can reduce production costs, and the noise that produces in the working procedure is less.
This programme is realized by following technical measures: this deep groove ball bearing retainer comprises the support body I and the support body II of mutual butt joint, support body I and support body II by the ball pocket and with each ball pocket be connected to the annular the plane constitute, at least three planes on the described support body I are provided with projection, the corresponding flat of support body II is provided with the positioning hole corresponding with projection, and projection is passed positioning hole and passed part and fixes with support body II welding.
The inner surface profile line that above-mentioned support body I and support body II go up single ball pocket is non-circular.
The camber line that the inner surface profile line that above-mentioned support body I and support body II go up single ball pocket is R2 by one section radius camber line that is R1 and two sections radiuses constitutes, and R1＜R2.
The inner surface profile line of above-mentioned support body I and the last single ball pocket of support body II is linked to each other with straight line by straight line, camber line and constitutes.
In order to realize above-mentioned purpose better, the utility model also provides a kind of employing to have the bearing of the deep groove ball bearing retainer that at least a feature is made in the above-mentioned feature.
The beneficial effect of this programme can learn that at least three planes on the support body I of this deep groove ball bearing retainer are provided with projection according to the narration to such scheme, and the corresponding flat of support body II is provided with the positioning hole corresponding with projection.After projection is passed positioning hole, projection and support body II are welded together.The retainer of this structure can be realized support body I and firm the welding together of support body II, does not adopt rivet to connect, and has both reduced cost of production and noise, can avoid occurring support body I and/or radially moving about of support body II and coming off of rivet again.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the plan view of the utility model embodiment.
Fig. 2 be among Fig. 1 A-A to the structural type one of sectional view.
Fig. 3 be among Fig. 1 A-A to the structural type two of sectional view.
Among the figure, 1 is the ball pocket, and 2 is the plane, and 3 is projection, and 4 is positioning hole, and 5 and 7 for radius is the camber line of R2, and 6 for radius is the camber line of R1, and 8 is support body I, and 9 is support body II, and 10 and 12 is straight line, and 11 is camber line.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by embodiment.
A kind of deep groove ball bearing retainer, as Fig. 1, Fig. 2 and shown in Figure 3, it comprises the support body I8 and the support body II 9 of mutual butt joint, support body I 8 and support body II 9 by ball pocket 1 and with each ball pocket 1 be connected to the annular plane 2 constitute, at least three planes 2 on the described support body I 8 are provided with projection 3, and the corresponding flat 2 of support body II 9 is provided with the positioning hole 4 corresponding with protruding 3.After projection 3 was passed positioning hole 4, end and support body II 9 with protruding 3 welded together.
The inner surface profile line of single ball pocket 1 is non-circular on described support body I 8 and the support body II 9.Can adopt following structural type specifically: (1) as shown in Figure 2, the inner surface profile line of single ball pocket 1 is that the camber line 7 that the camber line 6 of R1, camber line 5 that radius is R2 and radius are R2 constitutes by radius on support body I 8 and the support body II 9, and R1＜R2, radius are that the camber line 5 of R2 and camber line 7 that radius is R2 lay respectively at the two ends that radius is the camber line 6 of R1; (2) as shown in Figure 3, the inner surface profile line of single ball pocket 1 is linked to each other with straight line 12 by straight line 10, camber line 11 and constitutes on support body I 8 and the support body II 9.
In order to realize the function of above-mentioned deep groove ball bearing retainer, the utility model also provides a kind of bearing that adopts the deep groove ball bearing retainer that a kind of said structure feature makes at least.
Can pass through existing techniques in realizing without the technical characteristics of describing in the utility model, not repeat them here.
