Embodiment
Introduce the embodiment of this invention below in conjunction with accompanying drawing.
Present embodiment is the reversing arrangement that a kind of reciprocating force drives unidirectional power transmission output, comprises frame, live axle 13, the first transmission shaft 1, second driving shaft 5, actuation gear 12, the first driving gear 2, the second driving gear 3, the first overrunning clutch 9, the second overrunning clutch 10, first gear 8, second largest gear 11.
The first transmission shaft 1 is positioned at frame, and an end is installed in gear by bearing and installs on the side arm 4, the other end of the first transmission shaft 1 by bearing be installed in gear install on the frame 6; The first driving gear is being arranged between gear installation side arm 4 and the gear installation frame 6, and is fixedly mounted on described the first transmission shaft 1.
Described live axle 13, the first transmission shaft 1 and second driving shaft 5 threes' axis is parallel to each other.
The first overrunning clutch 9 gear install after-frame 7 and gear install between the frame 6.The inner ring of described the first overrunning clutch 9 is fixedly mounted on the second driving shaft 5, the outer ring of the first overrunning clutch 9 and first gear 8 are fixedly connected with by key, so that the inner ring of the first overrunning clutch 9 and second driving shaft 5 rotate together, outer ring and first gear 8 rotate together like this.
The second overrunning clutch 10 gear install after-frame 7 and gear install between the frame 6.The inner ring of described the second overrunning clutch 10 is fixedly mounted on the live axle 13, the outer ring of described the second overrunning clutch 10 and second largest gear 11 are fixedly connected with by key, so that the inner ring of the second overrunning clutch 10 and live axle 13 rotate together, outer ring and second largest gear 11 rotate together like this.
Described actuation gear 12 and the second driving gear 3 are identical, and engagement between described actuation gear 12 and the first driving gear 2, engagement between the first driving gear 2 and the second driving gear 3.
Described first gear 8 and second largest gear 11 are identical, engagement between first gear 8 and the second largest gear 11.
Fig. 2 be by first gear 8 be connected the scheme of installation that overrunning clutch 9 connects by key.Owing to the unidirectional force-transfer characteristic of overrunning clutch, be merely able to the moment of transfer of unidirectional between second driving shaft 5 and the first gear 8, in the present embodiment, second driving shaft 5 drives first gear 8 and rotates together when turning clockwise.Installation relation between second largest gear 11 and the second overrunning clutch 10 is identical with the matching relationship of first gear 8 and the first overrunning clutch 9.Described the second overrunning clutch 10 is opposite with the driving direction of the first overrunning clutch 9, so that the power transmission opposite direction of the second overrunning clutch 10 and the first overrunning clutch 9 drives second largest gear 11 and rotates together when namely live axle 13 is rotated counterclockwise.
Below in conjunction with Fig. 1, set forth specific works process of the present invention.During work, can apply reciprocating force when live axle 13 or actuation gear 12:
When live axle 13 is rotated counterclockwise, directly driving second largest gear 11 is rotated counterclockwise, be rotated counterclockwise by the first driving gear 2 drive the second driving gears 3 and second driving shaft 5 simultaneously, therefore second driving shaft 5 can not drive first gear 8, and second largest gear 11 drives first gear 8 idle running;
When live axle 13 turns clockwise, live axle 13 can not drive second largest gear 11, but turn clockwise by the first driving gear 2 drive the second driving gears 3 and second driving shaft 5, second driving shaft 5 drives first gear 8 and turns clockwise, and then drives first gear 11 and be rotated counterclockwise.
From above-mentioned working procedure as seen, no matter live axle 13 and actuation gear 12 are rotated counterclockwise or turn clockwise, second largest gear 11 all is rotated counterclockwise, and has realized that reciprocating force drives the function of unidirectional power transmission output.
If apply reciprocating force at second driving shaft 5 or the second driving gear 3 when using, identical with above-mentioned working principle, the output that always turns clockwise of final first gear 8 has realized that equally reciprocating force drives the function that unidirectional power transmission is exported.
