Abstract
The utility model discloses a steel-aluminum combined chain wheel, which is formed by a gear ring and an inner ring that are riveted by a rivet, the inner edge of the gear ring is provided with an installing supporting lug, the outer edge of the inner ring is provide with an installing groove, the installing supporting lug clings to the installing groove, the material of the gear ring is 45<#> steel, the material of the inner ring is aluminum alloy. The steel-aluminum combined chain wheel can meet the requirements of the mechanical performances such as impact resistance, fatigue resistance, high wearing, good obdurability and the like for the chain wheel of the motorcycle racing, meanwhile, the steel-aluminum combined chain wheel has light weight, low cost and is easy to produce.
Description
Technical field:
The utility model relates to a kind of sprocket wheel, especially relates to a kind of steel aluminium composite sprocket that is widely used on the motorcycle.
Technical background:
Characteristics such as chain wheel of motorcycle is the embodiment of transmission of motorcycle engine power and motorcycles drives, and desired strength is good, and wear-resisting and transmission distortion is low.At present, motorcycle rear driving wheel great majority all are to adopt steel, mainly are the 45# steel, Heavy Weight, and rigidity can realize common motorcycle basic need, mechanical strength can satisfy the requirement that motor cycle rear wheel drives substantially.Along with people's demand and environment requirement improves constantly and the needs of motorcycle race, require rear wheel drive to embody the performance of motorcycle engine better, so, engine output power can be fully used, thereby reduce the discharging of exhaust emission pollution, so just require the motorcycle overall weight to reduce, power is exported.Domestic many motorcycle enterprises are inside and outside participating nation during the motorcycle race, basically adopt external motorcycle racing car as the sprocket wheel of racing bicycle or employing import rear driving wheel to be transformed to reach competition effect, this weight and mechanical strength to the back sprocket wheel is all had higher requirement.Require sprocket wheel and chain when cooperating, should have certain impact power, force of sliding friction, fatigue stress also will have certain intensity, good wear resistance and higher strength and toughness and anti-fatigue ability.Tradition can not satisfy the performance requirement of motorcycle racing car far away as the sprocket wheel material with steel.
The defective of traditional chain wheel of motorcycle mainly contains: the one, owing to adopt the steel manufacturing, so weight is big, and the motorcycle overall weight is increased; The 2nd, get rusty easily the maintenance cost height.
The model utility content:
The purpose of this utility model provides a kind of steel aluminium composite sprocket, satisfy motorcycle racing blockchain wheel to mechanical properties such as wear resistancies in, this steel aluminium composite sprocket light weight, be easy to produce and with low cost.
For achieving the above object, the technical solution of the utility model is: design a kind of steel aluminium composite sprocket, its main points are: described sprocket wheel is by gear ring and inner ring is affixed forms, and described gear ring material is the 45# steel, and described inner ring material is an aluminum alloy.
The utility model adopts two kinds of made to form, and adopts the 45# steel to make gear ring, wear resistance good and higher strength and toughness and anti-fatigue ability; Adopt aluminum alloy to make inner ring, can alleviate the weight of sprocket wheel greatly.
Described gear ring inner edge is provided with the installation journal stirrup, and described inner ring outer rim is provided with mounting groove, and described installation journal stirrup and mounting groove are fitted, and use rivet, riveted joint to be permanent connection, and be easy for installation.
Be provided with lightening hole on described inner ring, described lightening hole is triangular in shape, and this lightening hole circumferentially is two rows and distributes, and the row's lightening hole base that is positioned at ring so can make weight of the present utility model become lighter near described inner ring.
Beneficial effect: its intensity of gear ring, the hardness that adopt the 45# steel to produce are higher, so wear resistance is good, the inner ring light weight that adopts aluminum alloy to produce, and density, intensity height, have good plasticity and corrosion resistance, thus the utility model not only wear resistance is good, and light weight.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B part structure for amplifying schematic representation of Fig. 2.
Meaning of each numbering is in the above-mentioned accompanying drawing: 1. gear ring, 2. inner ring is 3. installed journal stirrup, 4. rivet, 5. lightening hole.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
See also Fig. 1 and Fig. 2: shown in steel aluminium composite sprocket, form by gear ring 1 and inner ring 2, described sprocket wheel is by gear ring 1 and inner ring 2 affixed forming, described gear ring 1 inner edge is provided with installs journal stirrup 3, described inner ring 2 outer rims are provided with mounting groove, and described installation journal stirrup 3 is fitted with mounting groove, and rivet with rivet 4, and described gear ring 1 material is the 45# steel, and described inner ring 2 materials are aluminum alloy.
It can also be seen that in Fig. 1: be provided with lightening hole 5 on described inner ring 2, described lightening hole 5 is triangular in shape, and this lightening hole 5 circumferentially is two rows and distributes, and is positioned at the close described inner ring 2 in row's lightening hole 5 bases of ring.
