Description
Technical field
The utility model relates to technical field of automobile accessories, specifically a kind of first speed driven gear.
Background technique
Driven gear is a part belonged in auto parts and components, and it is passive to be mainly used for serving in a pinion, is used
In transmitting power effect, due to the extensive use of driven gear, disadvantage also increases therewith present on reproduction, due to driven tooth
Wheel is very high to retrofit requirement, and the annular groove and mounting groove of driven gear currently on the market are and repeatedly processing
At cumbersome production process and too long process time are very big on delicate mechanical influence.
Summary of the invention
The utility model provides a kind of first speed driven gear to solve the problems, such as that processing effect is bad in the prior art.
In order to solve the above-mentioned technical problem, the utility model embodiment discloses following technical solution：
A kind of first speed driven gear, including circle ring chamber, circle ring chamber inner surface set groove, and the groove is in around circumference
Cross-shaped, the surface of the groove is equipped with wearing layer, and the thickness of the wearing layer is at least the 1/10 of groove height.
Groove is rectangle.
The number of groove is even numbers group, and the number of the groove is at least 2 groups.
Groove is set as centrosymmetric structure.
Circle ring chamber is closed cavity structure, and the circle ring chamber surface is equipped with coating.
Coating upper surface is equipped with liquid-proof.
Two end surfaces of circle ring chamber are equipped with the transition rings of recess, and the height of the fixed ring is less than the height of circle ring chamber.
It further, is round and smooth excessive angle at the dog-ear of groove bottom end.
Further, there is gasket in circle ring chamber, the gasket is the wheel structure of axially symmetric structure.
Further, circular through hole is equipped in gasket, the number of through-holes on gasket is at least 5 pairs.
The groove of a kind of first speed driven gear of the utility model, surface setting rule carries out realizing positioning and bayonet function,
Irregular bayonet is optimized for puzzlement caused by processing, meanwhile, wearing layer is arranged in groove surfaces, effectively extends making for gear
With the service life, the utility model structure is simple, and design rationally, is widely used in mechanical processing industry.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Description needed in attached drawing be briefly described, it should be apparent that, for those of ordinary skills,
Under the premise of not making the creative labor, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of schematic perspective view of first speed driven gear provided by the utility model；
Fig. 2 is a kind of schematic perspective view of first speed driven gear gasket provided by the utility model；
Wherein：1, circle ring chamber；2, groove.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution in the utility model, below in conjunction with this reality
With the attached drawing in new embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that
The described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on the utility model
In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
The range of the utility model protection all should belong in example.
It please refers to shown in attached drawing 1, a kind of first speed driven gear, including circle ring chamber 1,1 inner surface of circle ring chamber sets groove
2, the groove 2 is around circumference in cross-shaped, and the surface of the groove 2 is equipped with wearing layer, and the thickness of the wearing layer is extremely
It is less the 1/10 of 2 height of groove.
Groove 2 is rectangle.
The number of groove 2 is even numbers group, and the number of the groove 2 is at least 2 groups.
Groove 2 is set as centrosymmetric structure.
Circle ring chamber 1 is closed cavity structure, and 1 surface of circle ring chamber is equipped with coating.
Coating upper surface is equipped with liquid-proof.
1 liang of end surfaces of circle ring chamber are equipped with the transition rings of recess, and the height of the fixed ring is less than the height of circle ring chamber 1
Degree.
It further, is round and smooth excessive angle at 2 bottom end dog-ear of groove.
Further, the circumscribed circle diameter of gasket is consistent with the interior circular diameter of circle ring chamber 1.
As shown in Fig. 2, there is gasket in circle ring chamber 1, the gasket is the wheel structure of axially symmetric structure.
