Abstract
The utility model relates to a nylon retainer structure of bearing, including the holder body, install the steel ball in the pocket hole of holder body, the internal surface in pocket hole has the recess, and annular column structure is arranged and formed to the recess along the interior cambered surface extension in pocket hole, be equipped with the through -hole that runs through the holder body in the recess, through -hole along the even interval arrangement of the anchor ring of recess. The utility model discloses in, setting up the recess in the pocket hole, the recess forms the radiating groove of steel ball, reduces the area of contact of pocket hole and steel ball to, be equipped with the through -hole of even interval arrangement in the recess, further reduce 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, provides a kind of nylon holding frame structure 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 nylon holding frame structure for bearing, comprises retainer body, and retainer body is nylon material, installs steel ball in the pocket hole of retainer body, and the inner surface belt in described pocket hole is fluted, and groove is arranged along the intrados extension in pocket hole and forms ring-shaped structure; The cross section of described groove is trapezium structure, and it is increased to the outside of retainer body gradually by the center in pocket hole; Be provided with the through hole running through retainer body in described groove, through hole is arranged along the anchor ring uniform intervals of groove.
Technique effect of the present utility model is:
In the utility model, pocket arranges groove in hole, and groove forms the radiating groove of steel ball, reduces the area of contact of pocket hole and steel ball, and, be provided with the through hole that uniform intervals is arranged in groove, reduce wearing and tearing further, increase the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
In figure: 1, retainer body; 2, pocket hole; 3, steel ball; 4, groove; 5, through hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1 and Figure 2, the nylon holding frame structure of the bearing of the present embodiment, comprise retainer body 1, retainer body 1 is nylon material, in the pocket hole 2 of retainer body 1, steel ball 3 is installed, the inner surface belt fluted 4 in pocket hole 2, groove 4 is arranged along the intrados extension in pocket hole 2 and forms ring-shaped structure; The cross section of groove 4 is trapezium structure, and it is increased to the outside of retainer body 1 gradually by the center in pocket hole 2; Be provided with the through hole 5 running through retainer body 1 in groove 4, through hole 5 is arranged along the anchor ring uniform intervals of groove 4.
In the utility model, arrange groove 4 in pocket hole 2, groove 4 forms the radiating groove of steel ball 3, reduces the area of contact of pocket hole 2 and steel ball 3, and, be provided with the through hole 5 that uniform intervals is arranged in groove 4, reduce wearing and tearing further, increase the service life.The cross section of groove 4 is trapezium structure, and is outwards increased gradually by the center in pocket hole 2, its objective is, central side near pocket hole 2 is small end, it can reduce the impact of groove 4 on the bearing capacity in pocket hole 2, and the central side away from pocket hole 2 is large end, and it can improve radiating effect.
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.
