Abstract
The utility model relates to an output gear for transmission structure of motorcycles, which comprises a gear body, a spline housing, a wedge clutch and a roll ball supporting component which are arranged between the gear body and the spline housing. Due to the support of the roll balls evenly distributed between the gear body and the spline housing, the utility model can bear certain axial force so that the abrasion of between the wedge and the gear body as well as the spline housing is reduced and the energy consumption is also reduced. The structure of the utility model is simplified by adopting the integrated structure of the gear body and the bearing. The utility model has the advantage of oil saving, rapid recovery of idle speed when the throttle is retarded, no easy fatigue or overheat and reduced mechanical wear of the mechanical part.
Description
Technical field
The utility model relates to the output gear of motor bike transmission device.
Background technology
The driving engine of motor bike drives the hind axle rotation by the output gear of transmission device.When motor bike was in sliding state, driving engine needn't work done, but driving engine moves under the reverse drive of transmission device, made idle work, had both wasted fuel oil, had increased the mechanical wear of driving engine again.China Patent No. is that 00248291.7 utility model patent specification sheets discloses a kind of automobile-used mono-directional overrun clutch, it is made of gear, main shaft, packing ring, back-up ring, spline housing, bearing installation is in gear, coaxial with gear, bearing is the Wedge-type special-shape bearing, retainer and outer retainer in evenly distributed many voussoirs in bearing, each voussoir have have spring leaf in the middle of the voussoir.Above-mentioned power-transfer clutch is as the output gear of motor bike, and when the rotating speed of trailing wheel passed to the rotating speed of hind axle greater than transmission device, this wedge clutch separated, and the engine idle operation does not influence motor bike and slides, not fuel consumption.But because the output gear of motor bike is a helical wheel, there is axial force in helical wheel, voussoir weares and teares easily with the position that gear, spline housing contact, period of service has been grown, contacting by the face contact between voussoir and gear, the spline housing progressively becomes a contact, influence the transmission of moment of torsion, and the noise generation is arranged when wedge clutch moves, so output gear needs transposing after using certain hour, service life is limited.
The utility model content
The purpose of this utility model is to propose a kind of output gear of the motor bike transmission device with mono-directional overrun clutch function of long service life.
For achieving the above object, the utility model has gear body, spline housing and is being on the basis of the wedge clutch between gear body and the spline housing, takes gear to be provided with the spin bearing assembly between gear body and spline housing.
Above-mentioned spin bearing assembly can respectively be provided with the groove as raceway on the opposite face of gear body and spline housing, be evenly distributed with spin between gear body recess and spline housing groove, and spin is separated by retainer.This structure is integrated radial ball bearing and gear.
Above-mentioned spin bearing assembly also can be a single-row radial ball bearing, and the single-row radial ball bearing outside is provided with circlip for bore and circlip for shaft.
The utility model is supported by the well-distributed spin between gear body and spline housing, can bear certain axial force, reduces the wearing and tearing of voussoir and gear body, spline housing, reduces energy consumption.The utility model can adopt gear and bearing integrated, simplifies the structure.Use motor bike of the present utility model to have fuel-economizing, can in time recover idling when receiving throttle, the driving engine indefatigability is overheated, the advantage of the mechanical wear of reduction mechanical part.

The specific embodiment
Fig. 1 and shown in Figure 2, present embodiment have gear body 1, spline housing 2, are provided with wedge clutch 3 and spin bearing assembly 4 between gear body 1 and the spline housing 2.Present embodiment is taked radial ball bearing and gear one, utilize gear body 1 and spline housing 2 respectively as the outer ring and the inner ring of radial ball bearing, spin bearing assembly 4 is made up of spin 4-1 and retainer 4-2, on the opposite face of gear body 1 and spline housing 2, respectively be provided with groove as raceway, spin 4-1 is evenly distributed between gear body recess and the spline housing groove, is separated by retainer 4-2 between the spin 4-1.The wedge clutch 3 of present embodiment can be buied from market, for example take that China Patent No. is 00240600.4, name is called disclosed wedge clutch in the utility model patent specification sheets of " overriding clutch with the shared retainer of voussoir ", the quantity of voussoir 3-1 is 17 can reach the ability that can transmit torque peak.
Shown in Figure 3, present embodiment has gear body 1, spline housing 2, is provided with wedge clutch 3 and spin bearing assembly 4 between gear body 1 and the spline housing 2.Spin bearing assembly 4 is a single-row radial ball bearing, and the single-row radial ball bearing outside is provided with circlip for bore 5 and circlip for shaft 6.
