Abstract
The utility model relates to a motorcycle part, in particular to an electric starting reduction gear. One end of the reduction gear is a drive gear of the starting motor, and the other end is a drive gear of the electric starting overrunning clutch. And an axle hole which comprises three sections is arranged through the inner portion of the reduction gear. Wherein the aperture size of the middle section is larger than that of the other two sections. Thereby the cylindricality of the inner hole can be fundamentally guaranteed, the grinding speed is largely increased, the production efficiency is improved, the starting abnormal noise is lowered, and the service life is lengthened.
Description
Affiliated technical field
The utility model relates to a kind of motorcycle parts, especially electric start and deceleration gear.
Background technique
At present, GY6 electricity start and deceleration gear is the electric starting gear of the bold and generous motorcycle engine of GY6, motor is by connecting power supply starting actuating motor, connecting actuating motor by electric start and deceleration gear then pilots engine with electricity starting free wheel device, because motor is when starting, it is high speed rotating, existing electric start and deceleration gear is when engine start, motor has abnormal sound, pass through test of many times, each engine works finds electric start and deceleration gear existing problems, and bore cylindricity deviation is too greatly the root of abnormal sound when causing engine start.In addition, these parts of electricity starting, it lubricates and has only less amount of lubrication oil to supply with, and the gap is very little between reduction gear and the reduction gear axle, and lubricant oil stays incessantly, and greasy property is relatively poor, axle and bore cause dry friction easily, and axle and bore wearing and tearing are very fast, and working life is shorter.
Summary of the invention
In order to overcome the deficiency of existing electric start and deceleration gear, the utility model provides a kind of electric start and deceleration gear, and this electricity start and deceleration gear can guarantee the cylindricity of endoporus.
The technological scheme that its technical problem that solves the utility model adopts is: electric start and deceleration gear, one is the actuating motor driving cog, and the other end is an electricity starting free wheel device driving cog, and internal run-through has axis hole, axis hole is divided into three sections, and the aperture of axis hole intermediate section is bigger than other two sections aperture.
Further: the aperture of axis hole intermediate section is than other two sections the big 0.5～1mm in aperture; The width of axis hole intermediate section is 5～10mm.
The beneficial effects of the utility model are, have solved the problem in grinding electricity start and deceleration bore difficulty, and its endoporus cylindricity has obtained assurance fundamentally, and grinding speed improves greatly, has improved manufacturing efficiency; Because the endoporus cylindricity is guaranteed, the contact gear ratio of electric start and deceleration bore and electric start and deceleration gear shaft is more even, and is stressed also relatively more even, when engine start, greatly reduces the starting abnormal sound; Because the existence of endoporus intermediate section, lubricant oil can be detained, and has guaranteed the oil lubrication between axle and endoporus, has reduced the wearing and tearing between them, has prolonged its working life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. axis hole intermediate sections among the figure.
Embodiment
Embodiment: GY6 electricity start and deceleration gear
As shown in Figure 1, GY6 electricity start and deceleration gear, one is actuating motor driving cog 1, the other end is an electricity starting free wheel device driving cog 2, internal run-through has axis hole 3, axis hole 3 is divided into 33 3 sections of motor side section 31, intermediate section 32 and clutch end sections, and the aperture of axis hole intermediate section 32 is 10.5mm, and two sections aperture is 10mm in addition.The width of axis hole intermediate section 32 is 8mm.Axis hole 3 is more even with the contact gear ratio of reduction gear axle, and forms a lubrication groove at intermediate section 32, has reduced wearing and tearing, and using effect is very good.
