Abstract
The utility model relates to a one-way clutch which belongs to the technical field of clutches. The clutch is provided with a sprocket outer and a roller cage, the inner blade face of the sprocket outer and the gap surface of the roller cage forming a wedge cavity, a roller positioned in the wedge cavity, so as to form the one-way clutch drive. The model solves the technical problems that the rectangular wheel and tooth clutches of the current motor bikes and fuel mopeds have unstable drive and easily broken teeth, having advantages of large drive torque, mild and smooth drive and without impact and abrasion.
Description
Technical field
The utility model relates to a kind of overrunning clutch that belongs to the Clutch Technology field.
Background technique
At present, the sprocket wheel of existing battery-operated motor cycle, fuel bicycle trailing wheel and the unidirectional rotation between wheel hub realize by ratchet and pawl arrangement.Ratchet is big to the ratchet rigid impulse, pawl ratchet intensity is low, and the broken teeth accident easily takes place, and only is applicable to low speed, underloading occasion but this structure exists.This has brought many troubles for the manufacturing enterprise and the user of battery-operated motor cycle, fuel bicycle.
Summary of the invention
The purpose of this utility model is exactly to provide overrunning clutch a kind of high reliability, that carry-over moment is big for solving disadvantages of background technology.
The purpose of this utility model is achieved in that it is provided with the chain drum overcoat; in the chain drum overcoat, be provided with roller rolling retainer in the ring; be fixed with gland in roller fender bracket both sides; gland rotates with roller rolling retainer, and roller rolling retainer is provided with gap, forms wedge shape cavity between the inner ring surface of this gap surface and chain drum overcoat; be provided with roller in this cavity; gap one side is provided with blind hole, is provided with stage clip in the blind hole, and stage clip one end contacts with roller.Described wedge shape cavity quantity is 3～5.
The utility model is compared background technique and had following advantage: 1. compare the click structure, the utility model carry-over moment is big, can carry big load; 2. the problem that broken teeth easily takes place existing click overrunning clutch can not appear in the utility model, and reliability is higher; 3. the utility model unidirectional self-lock is reliable, oppositely free smoothly, and strong shock resistance, carry-over moment is soft smooth-going, no impact wear.
Description of drawings
Fig. 1 is the utility model structure principle chart.
Embodiment
The utility model is further described by embodiment below in conjunction with accompanying drawing: as shown in Figure 1, when roller rolling retainer 2 rotates counterclockwise, roller 5 moves to right at the wedge shape cavity that the inner ring surface and the roller rolling retainer 2 gap surface of chain drum overcoat 1 form, and blocking roller rolling retainer 2 and chain drum overcoat 1, roller rolling retainer 2 drives 1 rotation of chain drum overcoat like this.When roller rolling retainer 2 clockwise rotated, roller 5 moved to left at wedge shape cavity, and this moment, roller rolling retainer 2 can only rotation, and can't drive chain drum overcoat 1 and rotate together, thus the transmission of formation one-way clutch.In order to make the clutch stable drive soft, be provided with blind hole in a side of the gap of roller rolling retainer 2, be provided with stage clip 3 in the blind hole, stage clip 3 outer ends are withstood roller 5 all the time.For fixedly roller rolling retainer 2 and roller 5, be provided with gland in the both sides of roller rolling retainer 2 axially, two glands connect by gland rivet hole 6.Gland will be seated in the gland shallow slot 8 on the chain drum overcoat 1.Be provided with tapped hole 7 at the center of roller rolling retainer 2, so that be connected with the pedal axle.On chain drum overcoat 1, be provided with chain drum hole 4, so that be connected with sprocket wheel.
Claims (2)
1, a kind of overrunning clutch; it is characterized in that: it is provided with the chain drum overcoat; be provided with roller rolling retainer in the ring in the chain drum overcoat, be fixed with gland in roller fender bracket both sides, gland rotates with roller rolling retainer; roller rolling retainer is provided with gap; form wedge shape cavity between the inner ring surface of this gap surface and chain drum overcoat, be provided with roller in this cavity, gap one side is provided with blind hole; be provided with stage clip in the blind hole, stage clip one end contacts with roller.
2, according to the described overrunning clutch of claim 1, it is characterized in that: described wedge shape cavity quantity is 3～5.
