The present invention relates to a kind of motorcycle transmission composite sprocket, including external toothing, wheel hub, rivet are moulded with steel；External toothing is the mating part of sprocket wheel and chain, continues to use traditional carbon structural steel matter, and wheel hub is the coupling part of sprocket wheel and buffer body, and using self-lubricating engineering plastics material, rivet is used for the connection of external toothing and wheel hub.First, the coefficient of friction of traditional carbon structural steels is 0.1 or so, and the coefficient of friction of self-lubricating engineering plastics is 0.04 or so, improves the rub proofness of sprocket hub；Secondly, the density of traditional carbon structural steels is 7.85g/cm3, and the density of self-lubricating engineering plastics is 2.2g/cm3, alleviate the weight of sprocket wheel itself；Finally, self-lubricating engineering plastics wheel hub can be produced in batches by injection mold, improve production efficiency, save producing cost.
Description
Technical field
The present invention relates 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, therefore is 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 transforming sprocket wheel, it is weight in the sector to improve power output
The direction of point research.At present, traditional sprocket wheel all uses carbon constructional quality steel mostly in material, has certain shock resistance
Power, high abrasiveness and fatigue durability.But as the continuous progress of technology, traditional steel chain wheel cause motorcycle integrally overweight,
The shortcomings of reducing power output, can not 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.
The content of the invention
It is an object of the invention to provide a kind of steel using new material to mould composite sprocket, and steel modeling composite sprocket is not only
The high-quality performance of traditional steel chain wheel is met, power output is also effectively improved, reduces production cost.
The technical scheme is that：
A kind of motorcycle transmission moulds composite sprocket, including external toothing, wheel hub, rivet with steel；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 coefficient of friction 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。
Wheelboss inner hole stressIts
In：F (θ) is the intensity of power, and r is wheelboss inner hole radius, and w is scale factor, the power summation being so applied on wheelboss inner hole
The boss of wheel hub is inserted into the groove of external toothing, and is fixed by rivet interlacement.Inserting fixation can make chain
When being assembled to sprocket wheel progress normal work, it not only ensure that external toothing and hub rotation synchronously but also effectively prevented external toothing and hub spindle
To separation.
The solution have the advantages that：
First, the coefficient of friction of traditional carbon structural steels is 0.1 or so, and the coefficient of friction 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. 2 is the front view of external toothing.
Fig. 3 is the front view of wheel hub.
Fig. 4 is wheelboss inner hole stress diagram.
Embodiment
The present invention is described in further detail below by specific embodiment, following examples be it is descriptive, no
It can be limited the scope of the invention with this.
A kind of motorcycle transmission sprocket wheel, including external toothing 1, wheel hub 2, rivet 3；External toothing 1 is matching somebody with somebody 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 the boss of wheel hub in sprocket wheel 2
In the groove of gear ring 1, and it is connected two parts by rivet 3.External toothing 1 can be so effectively guaranteed and wheel hub 2 works
It is synchronous, while improve power output.
The present invention it is reasonable in design because inserting fixation can make chain be assembled to sprocket wheel carry out normal work when, both ensured
External toothing and hub rotation are synchronous and effectively prevent external toothing and wheel hub axial separation.First, traditional carbon structural steels rub
It is 0.1 or so to wipe coefficient, and the coefficient of friction of self-lubricating engineering plastics is 0.04 or so, improves the wear-resisting journey 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, mitigate
The weight of sprocket wheel itself；Finally, self-lubricating engineering plastics wheel hub can be produced in batches by injection mold, improve production effect
Rate, save producing cost.
