Abstract
The utility model discloses an impact gear which comprises a gear body and a plurality of gear teeth arranged on the working surface of the gear body in a circular mode. A plurality of convex ribs are arranged on the outer surface of the gear body, and the convex ribs are all vertically arranged. According to the mentioned technical scheme, the convex ribs are arranged on the outer surface of the gear body, the convex ribs can be matched with the inner holes of a gearbox and can be embedded into an aluminum body, the interference fit of the convex ribs and the gearbox is guaranteed reliably, and the dimension accuracy of the matching holes of the gearbox can be reduced.
Description
Technical field
The utility model relates to the gear technique field, is specifically related to a kind of impact teeth.
Background technique
Existing impact teeth outer surface is arranged to smooth transition, when cooperating with the gearbox endoporus, if interference is bigger than normal, steel part easily excises the aluminium body of aluminum component bore area in press-fiting process, thereby can not guarantee reliable interference fit, to the dimension precision requirement height in gearbox hole.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of structure to arrange rationally, and is easily manufactured, low to gearbox matching hole dimension precision requirement, the impact teeth of reliable operation.
For achieving the above object, the utility model provides following technological scheme: a kind of impact teeth, comprise that denticle and annular are arranged on a plurality of teeth of denticle working surface, and the outer surface of described denticle is provided with many convex tendons.
By adopting technique scheme, at the denticle outer surface convex tendon is set, convex tendon can cooperate with the gearbox endoporus, and convex tendon can embed the aluminium body, can more reliable assurance and the interference fit of gearbox, can reduce gearbox matching hole dimensional accuracy.
The utility model further is set to: described many convex tendons all axially arrange at the denticle outer surface.By this setting, the utility model is easier to be cooperated with the gearbox endoporus.
The utility model further is set to: six convex tendons are set on the described denticle outer surface altogether, and evenly distribute around the denticle outer surface.By this setting, described convex tendon quantity arranges rationally, makes work more reliable.
The utility model also further is set to: a plurality of teeth on the described denticle working surface are obliquely installed respectively, and the angle that constitutes between per two teeth is 130 °-135 °.By this setting, the teeth angle arranges rationally, makes work more reliable.
The utility model also further is set to: the angle that the plane of inclination of described each teeth and denticle working surface constitute is 165 °-170 °.By this setting, angle arranges rationally between described teeth and the denticle working surface.
The utility model also further is set to: described denticle, a plurality of teeth and many convex tendons are made by the 35CrMo Alloy Constructional Steel.By this setting, one-piece element hardness height, it is more reliable to work.
The utility model has the advantages that: at the denticle outer surface convex tendon is set, convex tendon can cooperate with the gearbox endoporus, convex tendon can embed the aluminium body, can more reliable assurance and the interference fit of gearbox, can reduce gearbox matching hole dimensional accuracy, and angle arranges rationally between teeth and the denticle, and structure arranges rationally, reliable operation.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.

Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the disclosed a kind of impact teeth of the utility model, comprise that denticle 1 and annular are arranged on a plurality of teeth 2 of denticle 1 working surface, the outer surface of described denticle 1 is provided with many convex tendons 3, and described many convex tendons 3 all axially arrange at denticle 1 outer surface.
For making the utility model work more reliable, as preferably, on described denticle 1 outer surface of present embodiment six convex tendons 3 are set altogether, and evenly distribute around denticle 1 outer surface.
A plurality of teeth 2 on described denticle 1 working surface are obliquely installed respectively, and the angle that constitutes between per two teeth 2 can be 130 °-135 °.As preferably, the angle that constitutes between per two teeth 2 of present embodiment is 134 °.
The angle that the plane of inclination of described each teeth 2 and denticle 1 working surface constitute can be 165 °-170 °.As preferably, the angle that the plane of inclination of each teeth 2 of present embodiment and denticle 1 working surface constitute is 167.5 °.
In addition, described denticle 1, a plurality of teeth 2 and many convex tendons 3 are made by the 35CrMo Alloy Constructional Steel.Carburizing and quenching can guarantee that each position hardness of the flank of tooth is even after adopting 35CrMo, improves the reliability of part.
Above-described embodiment is to specific descriptions of the present utility model; only be used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection domain, the technician of related domain makes some nonessential improvement and adjusts the utility model according to the content of above-mentioned model utility and all falls within the protection domain of the present utility model.
