Abstract
The utility model discloses a be applied to four point angular contact ball bearing holder. It includes support body (1), ball pocket hole (5), and ball pocket hole (5) evenly distributed is opened slotted (4) on internal diameter (3) of support body (1) on support body (1), and the shape of groove (4) is square, and its opening width slightly is less than the diameter of ball pocket hole (5), and its degree of depth is 2/5 of steel ball (6) diameter. The utility model has the advantages of structural design is reasonable, superior performance is reliable, processing is convenient, when assembling the riveting the requirement of circumference location is not high, be difficult for producing the deformation, can improve bearing production efficiency and quality.
Description
Technical field
The utility model relates to a kind of retainer, especially a kind of entity copper retainer that is applied to 4 angular contact ball bearings.
Background technique
Bearing is a kind of being applied on the rotating mechanism, is used for the parts that support, reduce friction and bear load.The advantage that 4 angular contact ball bearing is simple in structure with it, boundary dimension is compact, can bear bi-directional axial power in bearing radial force, bearing capacity is strong, rated speed is high is widely used in automobile, marine gear gearbox, rolling machinery industry.In the prior art, the structure of 4 angular contact ball bearing entity copper retainers such as Fig. 1, Fig. 2, shown in Figure 3, its mainly by support body 1 ', cut mouthful 2 ', ball pocket hole 5 ' forms, be out of shape and make the diameter in ball pocket hole 5 ' reduce to pin steel ball by cutting mouthful 2 '.The shortcoming of this retainer is:
1, circumferential registration requires highly during riveted, and there have skew just may produce distortion slightly to be inhomogeneous, cuts mouthful to be out of shape as a certain ball pocket hole just to be easy to generate the ball phenomenon inadequately.
2, cut and make a slip of the tongue deeply, distortion just might make retainer crack slightly greatly, in addition might fritter copper to collapse the broken product that causes defective, such bearing copper scale in the running can cause the bearing critical defect.
Summary of the invention
The technical problems to be solved in the utility model provides 4 angular contact ball bearing cages that a kind of superior performance is reliable, be convenient to process and assemble riveted.
The technical scheme in the invention for solving the above technical problem is: these 4 angular contact ball bearing cages, comprise support body, ball pocket hole, and ball pocket hole is evenly distributed on the support body, and its structural feature is: have groove on the internal diameter of described support body.
Being shaped as of groove described in the utility model is square.
The A/F of groove described in the utility model is slightly less than the diameter in ball pocket hole.
The degree of depth of groove described in the utility model is 2/5 of a steel ball size.
The utility model compared with prior art has the following advantages: reasonable in design, easy to process, assembling less demanding to circumferential registration during riveted is difficult for producing distortion, can improve the manufacturing efficiency and the quality of bearing.

Embodiment
Referring to Fig. 4, Fig. 5, material of the present utility model is a copper, has groove 4 on the internal diameter 3 of its support body 1, and being shaped as of groove 4 is square, and the A/F of groove 4 is slightly less than the diameter in ball pocket hole 5, and the degree of depth of groove 4 is 2/5 of steel ball 6 diameters.
Referring to Fig. 6, bearing presses by illustrated assembling mould assembling, 4 angular contact ball bearing cages belong to the outer ring guiding, pressurize to counterdie 9 by patrix 8, make and press a little 10 to intermediate compression on groove 4 circumference, pin steel ball 6 from both sides, thereby outer ring 9, steel ball 6 and support body 1 are joined together the outer assembly of composition bearing.
Claims (4)
1, a kind of 4 angular contact ball bearing cages comprise support body, ball pocket hole, and ball pocket hole is evenly distributed on the support body, it is characterized in that: have groove (4) on the internal diameter (3) of described support body (1).
2,4 angular contact ball bearing cages according to claim 1, it is characterized in that: being shaped as of described groove (4) is square.
3,4 angular contact ball bearing cages according to claim 1, it is characterized in that: the A/F of described groove (4) is slightly less than the diameter in ball pocket hole (5).
4. 4 angular contact ball bearing cages according to claim 1 is characterized in that: the degree of depth of described groove (4) is 2/5 of steel ball (a 6) diameter.
