Description
Technical field
The utility model is related to a kind of motorcycle transmission sprocket wheel, more particularly to a kind of new-type steel modeling composite sprocket.
Background technology
In recent years, due to chain drive structure is simple, part is few characteristic so that all contra in terms of manufacture and repairing
Just, maintenance cost is reduced, is therefore widely used in motorcycle field.Wherein, chain wheel of motorcycle belongs to vehicle on motorcycle
Partial critical function part, therefore motorcycle overall weight is reduced by the way that sprocket wheel is transformed, it is weight in the sector to improve power output
The direction of point research.At present, traditional sprocket wheel has certain shock resistance mostly all using carbon constructional quality steel in material
Power, high abrasiveness and fatigue durability.But being constantly progressive with technology, traditional steel chain wheel cause motorcycle integrally overweight,
The shortcomings of reducing power output, cannot meet the needs of society, therefore propose higher requirement to the material of sprocket wheel, look for
It is urgent problem to a kind of material for not only having met the high-quality performance of steel chain wheel but also power output being improved.
Utility model content
The purpose of this utility model is to provide a kind of steel using new material to mould composite sprocket, steel modeling composite sprocket
The high-quality performance of traditional steel chain wheel is not only met, power output is also effectively improved, reduces production cost.
The technical solution of the utility model is：
A kind of motorcycle transmission moulds composite sprocket with steel, including external toothing, wheel hub, rivet；External toothing is sprocket wheel and chain
Mating part, continue to use traditional carbon structural steel matter, wheel hub is the coupling part of sprocket wheel and buffer body, using self-lubricating engineering
Plastic material, rivet are used for the connection of external toothing and wheel hub.
Self-lubricating engineering plastics material wheel hub is compared to traditional carbon structural steel matter wheel hub friction coefficient and reduces 2.5
Times, extend sprocket wheel service life.It is whole that self-lubricating engineering plastics material wheel hub is compared to traditional carbon structural steel matter wheel hub
Weight alleviates 3.5 times, reduces the weight of sprocket wheel itself.Assuming that inner wheel hub material selects traditional carbon structural steels respectively
Material, aluminium and self-lubricating engineering plastics, wherein, the density of traditional carbon structural steels is 7.85g/cm3, the density of aluminium is
2.7g/cm3, the density of self-lubricating engineering plastics is 2.2g/cm3。
The boss of wheel hub is inserted into the groove of external toothing, and is passed through rivet interlacement and fixed.Inserting fixation can make chain
When being assembled to sprocket wheel and being worked normally, it not only ensure that external toothing is synchronous with hub rotation but also effectively prevent external toothing and hub spindle
To separation.
The utility model has the technical effect that：
First, the friction coefficient of traditional carbon structural steels is 0.1 or so, and the friction coefficient of self-lubricating engineering plastics is
0.04 or so, improve the rub proofness of sprocket hub；Secondly, the density of traditional carbon structural steels is 7.85g/cm3, and moisten certainly
The density of sliding engineering plastics is 2.2g/cm3, alleviate the weight of sprocket wheel itself；Finally, self-lubricating engineering plastics wheel hub can lead to
Injection mold batch production is crossed, production efficiency is improved, saves producing cost.

Fig. 4 is wheelboss inner hole stress diagram.
Specific embodiment
The utility model is described in further detail below by specific embodiment, following embodiment is descriptive
, it is impossible to the scope of protection of the utility model is limited with this.
A kind of motorcycle transmission sprocket wheel, including external toothing 1, wheel hub 2, rivet 3；External toothing 1 is matching for sprocket wheel and chain
Part is closed, continues to use carbon structure steel material, wheel hub 2 is the coupling part of sprocket wheel and buffer body, using engineering plastics material, rivet
3 be the connector of external toothing and wheel hub.Its technical characteristics is：Motorcycle transmission is inserted into outer with 2 boss of wheel hub in sprocket wheel
In 1 groove of gear ring, and pass through the fixed two parts of the connection of rivet 3.It can be effectively guaranteed external toothing 1 in this way and wheel hub 2 works
It is synchronous, while improve power output.
The utility model is designed reasonably, because when inserting fixation can make chain be assembled to sprocket wheel to be worked normally, both
It ensure that external toothing is synchronous with hub rotation and effectively prevent external toothing and wheel hub axial separation.First, traditional carbon structural steels
Friction coefficient for 0.1 or so, and the friction coefficient of self-lubricating engineering plastics is 0.04 or so, improves the wear-resisting of sprocket hub
Degree；Secondly, the density of traditional carbon structural steels is 7.85g/cm3, and the density of self-lubricating engineering plastics is 2.2g/cm3, subtract
The light weight of sprocket wheel itself；Finally, self-lubricating engineering plastics wheel hub can be produced in batches by injection mold, improve production
Efficiency saves producing cost.
