Preferably, the cylindrical wall of described outer ring is step-like, comprise large end and two be connected to the small end of described large end both sides by step surface, two described small ends are circumferentially being provided with described roll extrusion decorative pattern as described injection moulding bite, and described large end is smooth, cylindrical peripheral surface.
Preferably, the cylindrical wall of described outer ring is step-like, and comprise large end and be connected to the small end of described large end side by step surface, described small end is circumferentially being provided with described roll extrusion decorative pattern as described injection moulding nip portion, and described large end is smooth, cylindrical peripheral surface.
Preferably, described roll extrusion decorative pattern is straight burr or reticulate pattern.
As can be seen from technique scheme, bearing unit provided by the invention, comprise outer ring, inner ring and be arranged on the roller between outer ring and inner ring by retainer, wherein, on the cylindrical wall of outer ring, injection moulding is connected with plastic end cover, the cylindrical wall of outer ring is provided with the injection moulding bite for connecting plastic end cover, and injection moulding bite is provided with concavo-convex roll extrusion decorative pattern;
By arranging the injection moulding bite with roll extrusion decorative pattern on the cylindrical wall of outer ring, the degree of finish at this place can be reduced, play anti-skidding effect, improve the snap-in force between plastic end cover and bearing outer ring cylindrical wall, plastic end cover is avoided to occur coming off and skidding in injection moulding and using process, contribute to improving the combination force after injection moulding between part, can improve bearing shaft to and the Anti-moving of radial direction, the ability of anti-slip.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The plan view of the outer ring of the bearing unit that Fig. 1 provides for the embodiment of the present invention;
The sectional view of the bearing unit that Fig. 2 provides for the embodiment of the present invention.
Embodiment
The invention provides a kind of bearing unit, to reach, the plastic end cover on it is firmly connected, avoid occurring the object of phenomenon that plastic end cover comes off or skids.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, the plan view of the outer ring of the bearing unit that Fig. 1 provides for the embodiment of the present invention; The sectional view of the bearing unit that Fig. 2 provides for the embodiment of the present invention.
A kind of bearing unit that the embodiment of the present invention provides, comprises outer ring 1, inner ring 4 and is 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 with plastic end cover, the cylindrical wall of outer ring 1 is provided with the injection moulding bite 1a for connecting plastic end cover, and injection moulding bite 1a is provided with concavo-convex roll extrusion decorative pattern.
Compared with prior art, the bearing unit that the embodiment of the present invention provides, by arranging the injection moulding bite 1a with roll extrusion decorative pattern on the cylindrical wall of outer ring 1, the degree of finish at this place can be reduced, play anti-skidding effect, improve the snap-in force 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 using process, contribute to improving the combination force after injection moulding between part, can improve bearing shaft to and the Anti-moving of radial direction, the ability of anti-slip.
Injection moulding bite 1a can be arranged on the multiple positions on the cylindrical wall of outer ring 1, such as, in an embodiment of the present invention, the cylindrical wall of outer ring 1 is overall as injection moulding bite 1a, cylindrical wall is circumferentially being provided with roll extrusion decorative pattern, this scheme can solve the problem that plastic end cover comes off and skids, but due in the course of working of bearing, the cylindrical wall of outer ring 1 is an important technological datum and process support face, be injection moulding bite 1a by the cylindrical wall whole installation of outer ring 1, and process roll extrusion decorative pattern, need significantly to improve existing bearing mnanufacture technique, cost is higher, even likely reduce the machining accuracy of bearing, lose more than gain.
Further, in the another kind of embodiment of the present invention, the cylindrical wall of outer ring 1 is step-like, comprise large end and two be connected to the small end of large end both sides by step surface, two small ends are circumferentially being provided with roll extrusion decorative pattern as injection moulding bite 1a, large end is smooth, cylindrical peripheral surface, all arrange injection moulding bite 1a also can solve plastic end cover come off in the both sides of outer ring 1 cylindrical wall, the problem of skidding, 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 to improve existing bearing mnanufacture technique, cost is caused to raise.
Therefore, in order under the prerequisite do not improved existing bearing mnanufacture technique, avoid coming off and slippage problems of plastic end cover, control technique improving cost, in embodiments of the present invention, the cylindrical wall of outer ring 1 is step-like, comprise large end and be connected to the small end of large end side by step surface, small end is circumferentially being provided with roll extrusion decorative pattern as injection moulding nip portion, large end is smooth, cylindrical peripheral surface, like this, the side of the cylindrical wall of outer ring 1 arranges roll extrusion decorative pattern as injection moulding nip portion, and opposite side is still smooth cylndrical surface, make the cylindrical wall of 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 harmful effect can not be caused to existing bearing machining precision.
In order to optimize technique scheme further, in embodiments of the present invention, roll extrusion decorative pattern is straight burr or reticulate pattern.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
