Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, a kind of one-way clutch of the present utility model, there is clutch
Circle 1, the endoporus both ends of clutch circle 1 are respectively arranged with a rolling bearing 2, are supported on two rolling bearings 2 and be provided with mandrel 3,
The inner surface of mandrel 3 is threadedly coupled with generator drive shaft.
Transmission circle 4, back-up ring 5 and friction spring 6 are provided between clutch circle 1 and mandrel 3, transmits the end face patch of circle 4
Tightly it is closely attached on the inner ring end face of another rolling bearing 2 in the inner ring end face of a wherein rolling bearing 2, the other end for transmitting circle 4,
Friction spring 6 includes bending end and natural extension end, and the bending end of friction spring 6 is fixed on transmission circle 4 and prevented using back-up ring 5
Only the bending end of friction spring 6 disengages from transmission circle 4；Clutch circle 1 at the outer end fillet of the neighbouring outer ring of rolling bearing 2
The riveting flange 1-1 for being used for wrapping the corresponding outer ring of rolling bearing 2 is formed after upper carry out riveting, on the clutch circle 1 at this, is entered
And the outer ring of two rolling bearings 2 is caused not produce relative displacement；The endoporus of clutch circle 1 is cylindricality through hole, and friction spring 6 is adopted
It is cylindrical spring, the outside dimension of friction spring 6 is more than the hole size of clutch circle 1.Transmit circle 4 and back-up ring 5 is in
Hollow convex structure, the cylindrical interference fit of endoporus and the mandrel 3 of circle 4 is transmitted, transmit the maximum of circle 4 and cylindrical be less than clutch
The endoporus of device circle 1, the minimum cylindrical and endoporus of back-up ring 5 for transmitting circle 4 are interference fitted.The outer ring of rolling bearing 2 and clutch circle 1
Endoporus interference fit, the inner ring of rolling bearing 2 and the cylindrical interference fit of mandrel 3.
When the rotating speed of the rotating ratio generator drive shaft of clutch circle 1 is high, friction spring 6 is cylindrical to swell and blocks clutch
The endoporus of device circle 1, generator drive shaft and clutch circle 1 are combined into one so that generator drive shaft and clutch circle 1 are same
Step rotation, transmit driving activity of force.When the rotating speed of the rotating ratio generator drive shaft of clutch circle 1 is low, friction spring 6 is cylindrical
The endoporus of simultaneously holdback clutch circle 1, the 1 each spinning of generator drive shaft and clutch circle are reduced, and then plays protection and buffering
Effect.
The belt being wrapped on clutch circle 1 moment of torsion is passed to successively clutch circle 1, friction spring 6, transmit circle 4 with
And mandrel 3, specific transmittance process are as follows：
First, belt delivers torque to clutch circle 1 first；
2nd, friction spring 6 it is cylindrical swell after frictional force is produced between the endoporus of clutch circle 1, clutch circle 1 passes through
The frictional force delivers torque to friction spring 6；
3rd, because the bending end of friction spring 6 is fixed on transmission circle 4, therefore friction spring 6 delivers torque to transmission circle again
4；
4th, because transmitting the endoporus of circle 4 and the cylindrical interference fit of mandrel 3, therefore transmit circle 4 and deliver torque to mandrel 3 again；
5th, because the inner surface of mandrel 3 is threadedly coupled with generator drive shaft, therefore mandrel 3 finally delivers torque to generating
Machine drive shaft.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
