Abstract
The utility model discloses a light chain wheel which comprises a wheel disc and chain wheel teeth. The chain wheel teeth are arranged at the outer edge of the wheel disc and are peripherally uniformly distributed, lightening holes, assembling holes and adjusting holes which are distributed in a central symmetry manner around the center of the wheel disc are arranged on the wheel disc, the diameter of each assembling hole is larger than that of each adjusting hole, the assembling holes, the lightening holes and the adjusting holes are sequentially arranged from the inside to the outside of the wheel disc, each adjusting hole and the corresponding assembling hole are arranged between the two corresponding adjacent lightening holes, an arc is arranged at the outer side edge of each lightening hole, the outer side edges of all the lightening holes are parts of the same circumference, another arc is arranged at the inner side edge of each lightening hole, the inner side edges of all the lightening holes are parts of the same circumference, and the inner side edges of the lightening holes and circle centers of the adjusting holes are positioned on the same circumference. The light chain wheel has the advantages that the excellent stability of the chain wheel is guaranteed when the chain wheel rotates, deflection of the chain wheel is prevented, and the attractiveness of the light chain wheel is improved while the rotational stability of the chain wheel is guaranteed.
Description
Technical field
The utility model relates to the lightweight sprocket wheel.
Background technology
Most of locomotive, especially motor bike, the chain transmission is one of its powerdriven principal mode, by sprocket wheel and chain cooperate finish, sprocket wheel is topmost parts in the chain transmission process.
In the existing sprocket wheel, through updating of technical matters, alleviating deadweight and improving technical elements such as its intensity by self structure and obtained certain effect.But the existing sprocket wheel later stage installs and operates inconvenience when adjusting, and stability is not good during rotation, and is being weak aspect the center of gravity controllability more, especially for realizing that improving sprocket wheel intensity causes its bodily form heaviness, influences self and assembles the aesthetic property of effect.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of lightweight sprocket wheel, can realize the simple, light of sprocket wheel self structure, good looking appearance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of lightweight sprocket wheel, comprise wheel disc and be located at the wheel disc outer, circumferential uniform sprocket, the center that described wheel disc is provided with wheel disc is that basic point is made the lightening hole that the center is symmetrically distributed, assembly opening and adjustment hole, the diameter of described assembly opening is greater than the diameter of adjustment hole, described assembly opening, lightening hole and adjustment hole arrange on wheel disc from inside to outside in proper order, be equipped with an adjustment hole and an assembly opening between any two lightening holes, the outer side edges of described lightening hole is one section circular arc, the outer side edges of all lightening holes is the part of same circumference, the inner side edge of described lightening hole also is one section circular arc, the inner side edge of all lightening holes is the part of same circumference, and the outer side edges of described lightening hole and the center of circle of adjustment hole are positioned on the same circumference.
As a kind of improvement, described lightening hole, assembly opening and adjustment hole are equipped with 4.
As a kind of improvement, the line of described adjustment hole center and wheel disk center passes the center of assembly opening.
The technical solution adopted in the utility model, its beneficial effect is: the inner side edge of lightening hole also is one section circular arc, the inner side edge of all lightening holes is the part of same circumference, the outer side edges of described lightening hole and the center of circle of adjustment hole are positioned on the same circumference, be equipped with an adjustment hole and an assembly opening between any two lightening holes, what guarantee sprocket wheel self rotates the stability of fashion, beat can not take place, and guarantees that sprocket rotation stability has improved its aesthetic property simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
The structural representation of a kind of embodiment of the utility model as shown in Figure 1, a kind of lightweight sprocket wheel, comprise wheel disc 1 and be located at the wheel disc outer, circumferential uniform sprocket 2, the center that described wheel disc is provided with wheel disc is that basic point is made the lightening hole 3 that the center is symmetrically distributed, assembly opening 4 and adjustment hole 5, the diameter of described assembly opening is greater than the diameter of adjustment hole, described assembly opening, lightening hole and adjustment hole arrange on wheel disc from inside to outside in proper order, be equipped with an adjustment hole and an assembly opening between any two lightening holes, the outer side edges 6 of described lightening hole is one section circular arc, the outer side edges of all lightening holes is the part of same circumference, the inner side edge 7 of described lightening hole also is one section circular arc, the inner side edge of all lightening holes is the part of same circumference, and the outer side edges of described lightening hole and the center of circle of adjustment hole are positioned on the same circumference.
In the present embodiment, described lightening hole, assembly opening and adjustment hole are equipped with 4.
The line of described adjustment hole center and wheel disk center passes the center of assembly opening.
The inner side edge of lightening hole also is one section circular arc, the inner side edge of all lightening holes is the part of same circumference, the outer side edges of described lightening hole and the center of circle of adjustment hole are positioned on the same circumference, be equipped with an adjustment hole and an assembly opening between any two lightening holes, what guarantee sprocket wheel self rotates the stability of fashion, beat can not take place, guarantee that sprocket rotation stability has improved its aesthetic property simultaneously.
Except above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
