The front view of the outer ring of the bearing assembly that Fig. 1 provides for this utility model embodiment;
The sectional view of the bearing assembly that Fig. 2 provides for this utility model embodiment.
Detailed description of the invention
This utility model provides a kind of bearing assembly, and to reach to make, plastic end cover thereon is firm to be connected, it is to avoid the purpose of phenomenon that plastic end cover comes off or skids occur.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to the front view of the outer ring of the bearing assembly that Fig. 1 and Fig. 2, Fig. 1 provide for this utility model embodiment; The sectional view of the bearing assembly that Fig. 2 provides for this utility model embodiment.
A kind of bearing assembly that this utility model embodiment provides, including outer ring 1, inner ring 4 and be arranged on the roller 2 between outer ring 1 and inner ring 4 by retainer 3.
Wherein, on the cylindrical wall of outer ring 1, injection moulding is connected to plastic end cover, the cylindrical wall of outer ring 1 is provided with the injection moulding bite 1a for connecting plastic end cover, and is provided with concavo-convex rolling decorative pattern on injection moulding bite 1a.
Compared with prior art, the bearing assembly that this utility model embodiment provides, by arranging the injection moulding bite 1a with rolling decorative pattern on the cylindrical wall of outer ring 1, the fineness at this place can be reduced, play anti-skidding effect, improve the gmatjpdumamics between plastic end cover and bearing outer ring 1 cylindrical wall, plastic end cover is avoided to occur coming off and skidding in injection moulding and use procedure, be favorably improved the adhesion between part after injection moulding, it is possible to increase bearing Anti-moving axially and radially, anti-slip ability.
Injection moulding bite 1a can be arranged on the multiple positions on the cylindrical wall of outer ring 1, such as, in this utility model one embodiment, the cylindrical wall of outer ring 1 is overall as injection moulding bite 1a, cylindrical wall is circumferentially provided with rolling decorative pattern, this scheme can solve the problem that the problem that plastic end cover comes off and skids, but due in the course of processing of bearing, the cylindrical wall of outer ring 1 is an important technological datum and process support face, it is injection moulding bite 1a by the cylindrical wall whole installation of outer ring 1, and process rolling decorative pattern, need existing bearing mnanufacture technique is greatly improved, relatively costly, it could even be possible to reduce the machining accuracy of bearing, lose more than gain.
Further, in this utility model another kind embodiment, the cylindrical wall of outer ring 1 is step-like, it is connected to the big small end holding both sides by step surface including big end and two, two small ends are circumferentially provided with rolling decorative pattern as injection moulding bite 1a, big end is smooth, cylindrical peripheral surface, be respectively provided with in the both sides of outer ring 1 cylindrical wall injection moulding bite 1a also be able to solve plastic end cover come off, the problem skidded, but with above-mentioned using overall for the cylindrical wall of outer ring 1 the same as the scheme of injection moulding bite 1a, need existing bearing mnanufacture technique is improved, cause that cost raises.
Therefore, in order under the premise existing bearing mnanufacture technique not improved, avoid coming off and slippage problems of plastic end cover, control technological improvement cost, in this utility model embodiment, the cylindrical wall of outer ring 1 is step-like, it is connected to the big small end holding side including big end and by step surface, small end is circumferentially provided with rolling decorative pattern as injection moulding nip portion, big end is smooth, cylindrical peripheral surface, so, the side of the cylindrical wall of outer ring 1 arranges rolling decorative pattern as injection moulding nip portion, and opposite side is still the smooth face of cylinder, the cylindrical wall making outer ring 1 still can as technological datum and process support face in bearing machining process, avoid and existing bearing mnanufacture technique is improved, and existing bearing machining precision will not be had undesirable effect.
In order to optimize technique scheme further, in this utility model embodiment, rolling decorative pattern is straight burr or reticulate pattern.
In this specification, each embodiment adopts the mode gone forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually referring to.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this utility model. The multiple amendment of these embodiments be will be apparent from for those skilled in the art, and generic principles defined herein when without departing from spirit or scope of the present utility model, can realize in other embodiments.
