Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-11:
Full-automatic little torque drive clutch 1, that a side at driving gear 10 is provided with cartridge type cylinder 11, the radially resetting means that is symmetrically arranged with the centrifugal slider 40 that only can do to move radially in the cartridge type cylinder 11 and centrifugal slider 40 is radially inwardly resetted, the projection 44 of the outer surface setting of centrifugal slider 40 can pass the through hole on cartridge type cylinder 11 sidewalls, one side of driven gear 20 is provided with cylinder type groove 21, the outer surface of the internal surface of cylinder type groove 21 and cartridge type cylinder 11 is slidingly matched, and is provided with the projection 22 that the projection 44 on the restriction centrifugal slider 40 circumferentially moves on the internal surface of cylinder type groove 21.
The exterior edge face of above-mentioned cartridge type cylinder 11 is provided with capping 30.
The concrete structure of above-mentioned radially resetting means is: be provided with axial spring locating column 43 on the inner side surface of each clutch slider 40, be provided with spring mounting hole 18 in the cartridge type cylinder 11 corresponding with each spring locating column 43, the outer end of the spring 50 of spring mounting hole 18 interior installations is socketed on the spring locating column 43 of clutch slider 40, is provided with the gap that moves radially of spring locating column 43 between the internal surface of the outer of spring locating column 43 and cartridge type cylinder 11.
Why spring 50 axially arranges, and is because driving gear 10 only needs less power centrifugal slider 40 can be drawn to initial position after stopping operating, and projection 44 is separated with projection 22, and then reach the purpose that driving gear 10 separates with driven gear 20; And the rotation of driving gear 10 can make by the reposition force that very little centrifugal force namely overcomes spring 50 centrifugal slider 40 radially outwards move to projection 44 and protruding 22 combinations, and then makes driving gear 10 and driven gear 20 combinations.
The concrete structure that is symmetrically arranged with the centrifugal slider 40 that only can do to move radially in the above-mentioned cartridge type cylinder 11 is: be symmetrically arranged with slide rail 14 radially in the cartridge type cylinder 11, be provided with chute on the side of the centrifugal slider 44 that contacts with slide rail 14, the chute of centrifugal slider 40 radially slides at described slide rail 14.
Above-mentioned slide rail 14 has two, chute on the centrifugal slider 40 is formed by two axial projections 42 that are arranged on quadrant 41 inner side surfaces, spring locating column 443 on the centrifugal slider 40 is positioned at the central part of chute, and the projection 44 of centrifugal slider 40 is arranged on the outer side surface of quadrant 41.
The concrete structure of the projection 22 on above-mentioned cylinder type groove 21 internal surfaces is: relative bilateral symmetry is provided with axial projection 22 on cylinder type groove 21 internal surfaces; Circumferential movement and then drive driven gear 20 after projection 44 on the projection 22 restriction centrifugal sliders 40 on the cylinder type groove 21 stretches out rotate with driving gear 10.
Above-mentioned driving gear 10 and gear 71 engagement driving on motor 70 axles, one-level gear 61 engagement driving on driven gear 20 and the gear-box 60.
After the rotating speed of motor 70 reaches the rotating speed of setting, centrifugal slider 40 throws away along slide rail 14 radially outwards under the effect of centrifugal force, projection 44 on the centrifugal slider 40 stretches out and is blocked by the projection 22 on the driven gear 20 afterwards, so the rotation of driving gear 10 drives driven gears 20 by the projection 44 on the centrifugal slider 40 and projection 22 and rotates; When motor 70 shut down or rotating speed less than the rotating speed of setting after, the centrifugal force of centrifugal slider 40 reduces, under the effect of the reposition force of Returnning spring 50, centrifugal slider 40 radially inwardly slides into the restriction that projection 44 breaks away from projection 22, so that driving gear 10 separates with driven gear 20, said process is the working procedure of the utility model driving gear 10 and driven gear 20 clutches.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
