Description
Technical field
The utility model relates to a kind of gear, and particularly a kind of motorcycle trunnion shaft driving gear belongs to field of mechanical technique.
Background technique
Trunnion shaft is to be used for balance and reduce the vibration of motorcycle engine, to reach the minimizing engine luggine, reduces the noise of motor, prolongs motor working life, promotes the purpose of driver's comfort level.The trunnion shaft technology is to use a wider technology in the motorcycle engine, and it simple and practical can be alleviated the car load vibration of motorcycle effectively, improves the travelling comfort of driving.In the trunnion shaft technology, it is no gap highi degree of accuracy middle-carbon steel carburizing and quenching gear that gear adopted at present, and this gear rotational speed is 10000～12000rpm, the accuracy of gear is more than 6 grades, high-speed motion noise 85db, so this gear noise is big, the precision height, assembly need all carry out dynamic balance running.At present in the motorcycle of having used the trunnion shaft technology, the ubiquity noise is big, and service life of gear is short, manufacturing efficiency is low, and accuracy of gear height can't domesticize and cause problems such as cost is surging.Therefore be necessary very much the gear structure in the motorcycle trunnion shaft technology is improved.
The model utility content
The purpose of this utility model just is at problems of the prior art, provides a kind of cost low, low, the long service life of noise, and the manufacturing efficiency height, the motorcycle driving gear that the material utilization rate is high is applied in the trunnion shaft and bent axle of motorcycle engine.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of motorcycle driving gear, be arranged in the trunnion shaft and bent axle of motorcycle engine, comprise wheel body and the ring gear that is fixed on the wheel body outer rim, the ring gear outer rim has some along the circumferential direction equally distributed teeth, described wheel body is made by powder metallurgy, ring gear is made by the high-strength nylon reinforcing material, the wheel body outer rim is special-shaped groove structure, ring gear is inner to be the special-shaped spline structure that is complementary with the wheel body outer rim, wheel body and ring gear by special-shaped spline and special-shaped groove card and be fixed together, fully reduced the contraction deformation of ring gear, satisfied the required precision of ring gear injection moulding.
With in the driving gear, described wheel body center has through hole at above-mentioned motorcycle, and described through-hole wall has axially extended groove.Through hole in the wheel body is used for linking to each other with trunnion shaft, has axially extended groove on the through-hole wall, makes gear compact more with being connected of trunnion shaft.
With in the driving gear, there is U-groove bevel in the described wheel body outside at above-mentioned motorcycle.This U-groove bevel makes gear compact more with being connected of trunnion shaft or bent axle.
Compared with prior art, advantage of the present utility model is: the utility model motorcycle adopts powder metallurgy forming with the driving gear wheel body, ring gear adopts the molding and forming of high-strength nylon reinforcing material, compare with available technology adopting steel material, manufacture cost is 1/5 of a steel material, and cost has obtained reducing greatly.
What ring gear adopted is the high-strength nylon reinforcing material, compared with the steel part gear, can reduce the noise that gear produces greatly in transmission process, noise is not higher than 75db yet in the high-speed motion process, satisfy the ambient noise requirement, and to be applied to the driving gear on the bent axle and to be applied to driven gear on the trunnion shaft all be the same spline structure that adopts, and the accuracy of gear can reduce.
High-strength nylon reinforcing material wear resistance is good, and wear extent is 65% of a steel part under the same terms, therefore can prolong the working life of gear.
Powder metallurgy forming and molding and forming material utilization rate all can reach more than 95%, and steel part rapidoprint utilization ratio is about 32%, so the utility model stock utilization can improve more than 2 times, have saved the consumption of material.
The precision injection molding time is 35s, is 10% of the plain steel Gear Production time, has improved the manufacturing efficiency of gear greatly.

Embodiment
The utility model is described in further detail with concrete enforcement below in conjunction with accompanying drawing, but the utility model is not limited to these embodiments.
Referring to Fig. 1 to Fig. 4, the utility model motorcycle is divided into driving gear and driven gear with driving gear, driving gear is set on the bent axle, driven gear is set on the trunnion shaft, the utility model gear has comprised wheel body 1 and has been fixed on the ring gear 2 of wheel body 1 outer rim, ring gear 2 outer rims have some along the circumferential direction equally distributed teeth 3, wheel body 1 is made by powder metallurgy, ring gear 2 is made by the high-strength nylon reinforcing material, wheel body 1 outer rim is special-shaped groove structure, the inner special-shaped spline structure of ring gear 2, wheel body 1 and ring gear 2 for being complementary with wheel body 1 outer rim by special-shaped spline and special-shaped groove card and be fixed together.Wheel body 1 center has through hole 4, and through hole 4 inwalls have axially extended groove 5, and wheel body 1 outside has had U-groove bevel 6.
The utility model motorcycle is divided into driving gear and driven gear with driving gear, driven gear be set on the trunnion shaft be set in bent axle on driving gear be meshed, bent axle drives driving gear and rotates, driving gear drives driven gear and rotates, and the rotation of the rotation of driven gear and then drive trunnion shaft, the rotation of trunnion shaft is used for the inertial force that balance crankshaft produces because of to-and-fro motion, makes engine mildness.The wheel body of powder metallurgy forming and the gear low cost of manufacture that combines with the ring gear of high-strength nylon reinforcing material molding and forming, operating noise is little, long service life, material utilization rate height can also reduce the machining accuracy of gear simultaneously, enhances productivity.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technological schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite also should be considered as protection domain of the present utility model.
