Abstract
The utility model relates to a low wearing and tearing holder of bearing, including the holder body, install the steel ball in the pocket hole of holder body, the internal surface in pocket hole is equipped with to the convex sand grip in pocket hole center, and annular column structure is arranged and formed to the sand grip along the interior cambered surface extension in pocket hole, and two annular convex bar relatively perpendicular arrange. The utility model discloses in, setting up the sand grip in the pocket hole, the steel ball contacts with the sand grip, reduces the area of contact of pocket hole and steel ball greatly, reduces wearing and tearing, increase of service life.
Description
Technical field
The utility model relates to technical field of bearings, the retainer particularly in bearing.
Background technique
In prior art, the pocket hole of the retainer of bearing is spheric structure, and after Dou Kongguo Baogang ball, both area of contact are larger, thus friction is between the two larger, worn steel ball can be caused serious, and easily occur the phenomenon that steel ball card pauses, the wearing and tearing of steel ball and retainer shorten the working life of bearing.
Model utility content
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provides a kind of low wearing and tearing retainer of bearing, and the friction of itself and steel ball is little, has the feature of long service life.
In order to solve the problem, the utility model adopts following scheme:
A kind of low wearing and tearing retainer of bearing, comprise retainer body, install steel ball in the pocket hole of retainer body, the internal surface in described pocket hole is provided with the raised line protruded to Dou Kong center, raised line is arranged along the intrados extension in pocket hole and forms ring-shaped structure, and two ring rib Relative vertical are arranged.
Technique effect of the present utility model is:
In the utility model, pocket arranges raised line in hole, and steel ball contacts with raised line, greatly reduces the area of contact of pocket hole and steel ball, reduces wearing and tearing, increases the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, retainer body; 2, pocket hole; 3, steel ball; 4, raised line.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, the low wearing and tearing retainer of the bearing of the present embodiment, comprise retainer body 1, in the pocket hole 2 of retainer body 1, steel ball 3 is installed, the internal surface in pocket hole 2 is provided with the raised line 4 protruded to center, pocket hole 2, raised line 4 is arranged along the intrados extension in pocket hole 2 and forms ring-shaped structure, and two ring rib 4 Relative vertical are arranged.
In the utility model, arrange raised line 4 in pocket hole 2, steel ball 3 contacts with raised line 4, greatly reduces pocket hole 2 and the area of contact of steel ball 3, reduces wearing and tearing, increase the service life.
Above illustrated embodiment is better embodiment of the present utility model, only be used for conveniently the utility model being described, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristics, utilize the utility model disclose the Equivalent embodiments changed or modify in the done local of technology contents, and do not depart from technical characteristics content of the present utility model, all still belong in the scope of the utility model technical characteristics.
