Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments.
nullAs depicted in figs. 1 and 2，This generator overrunning belt pulley，Including being connected wheel hub 1 and the axle sleeve 4 being connected with axletree with belt，Bearing outer ring 2 is connected in inside wheel hub 1，Axle sleeve 4 is connected in inside bearing inner race 3，It is provided with ball between bearing outer ring 2 and bearing inner race 3，Have several along the extension 3a equally distributed gradient groove 3b of circumference on the 3a lateral wall, extension that bearing inner race 3 stretches out，Gradient groove 3b is shaped as rectangle，Retainer 5 is sheathed to be fixed on the 3a of extension，Unilateral bearing outer ring 6 is sheathed on retainer 5，And unilateral bearing outer ring 6 is fixed on inside wheel hub 1，Unilateral bearing outer ring 6 away from bearing outer ring 2 side against there being ball bearing 9，This ball bearing 9 is set on axle sleeve 4，And ball bearing 9 is connected in inside wheel hub 1，It is equipped with needle roller between several gradient groove 3b and retainer 5，And it is provided with spring leaf 7 between the wherein side and retainer 5 of needle roller，Under the elastic force effect of spring leaf 7 needle roller part stretch out retainer 5 can be with the interior side contacts of unilateral bearing outer ring 6.
Say further, in order to prevent retainer 5 from play phenomenon occurring, extension 3a is axially connected with two Clip Reeds 8 along extension 3a, and two Clip Reeds 8 two ends with retainer 5 respectively lean.
Furthermore, bearing outer ring 2 is all fixed with annular dustproof sheet with the outer end of ball bearing 9.
As it is shown on figure 3, spring leaf on this generator overrunning belt pulley 7 and needle roller against the curved lamellar in one end, the other end of spring leaf 7 is fixed on retainer 5.
This generator overrunning belt pulley, wheel hub 1 drives the rotor of electromotor to rotate by transmission band, when axletree rotates, axle sleeve 4 drives bearing inner race 3 to rotate with axletree, now bearing inner race 3 and bearing outer ring 2, the rotating speed of equidirectional rotation and bearing inner race 3 is done more than bearing outer ring 2 and the rotating speed of unilateral bearing outer ring 6 in unilateral bearing outer ring 6, under the effect of spring leaf 7 elastic force and frictional force, needle roller is clamped between the extension 3a of bearing inner race 3 and unilateral bearing outer ring 6, bearing inner race 3 and unilateral bearing outer ring 6 combine and do the most synchronized rotary motion, unilateral bearing outer ring 6 drives wheel hub 1 to rotate together, wheel hub 1 makes the rotor of electromotor rotate with generating further through transmission band.nullAnd when axletree rotating speed changes，Check configuration ensures that wheel hub 1 can only rotate in one direction，I.e. when the rotating speed that bearing inner race 3 occurs moment reversion or bearing inner race 3 to make the rotating speed of bearing inner race 3 be less than bearing outer ring 2 and unilateral bearing outer ring 6 with axle reduction with axletree，Frictional force overcomes the elastic force of spring leaf 7，Needle roller departs from bearing inner race 3 surface，Extension 3a and unilateral bearing outer ring 6 are disengaged position，Now unilateral bearing outer ring 6 will not be affected by bearing inner race 3 and be inverted，Original duty is kept with the connected wheel hub 1 in unilateral bearing outer ring 6，Wheel hub 1 and belt pulley will not be impacted，Extend the service life of transmission band，And wheel hub 1 will not be sent out and turn，So coil in engine rotor also will not invert and produce moment negative electricity，Coil will not be by plus-minus electric impact，Extend the service life of coil，Afterwards after the rotating speed of bearing inner race 3 promotes again，The extension 3a of bearing inner race 3 can be bound together again with unilateral bearing outer ring 6 and do the most synchronized rotary motion，The wheel hub 1 being connected with unilateral bearing outer ring 6 together rotates.
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or use similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
