Embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Fig. 1--as shown in the of 6, a kind of nested nebenkern automatic clutch unidirectional transmission, comprises driving wheel 1, follower 2 and several assembly parties, and wherein, each assembly parts comprises free movable frame 8, clutch arm 6, support 11, clutch pinion 4 and ball 10; Driving wheel 1 is nebenkern with follower 2, and clutch arm 6 distributes along the surperficial even circumferential of driving wheel 1, and clutch arm 6 runs through the middle-end that is fixed on free movable frame 8; Ball 10 has two, lays respectively at the two bottom sides at free movable frame 8, and support 11 is fixed on free movable frame 8, be positioned at a side of clutch arm 8, the center of circle of clutch pinion 4 is fixed on support 11 tops, and clutch pinion 4 is provided with gear teeth I5, follower 2 is provided with gear teeth II3, and gear teeth I5 engages with gear teeth II3.
The surface of driving wheel 1 is provided with ball cave 12, and ball 10 is arranged in ball cave 12.
Free movable frame 8 is curved panel, and its tortuosity, bending direction are consistent with tortuosity, the bending direction of driving wheel 1.
Clutch arm passes through on the base plate that hole 9 is positioned at free movable frame 8, and at the other end of support 11 correspondences, penetrating hole is rectangle.
The both sides that hole 9 is passed through in clutch arm in the bottom of free movable frame 8 are provided with the slip locating channel 13 that leads to two ends, corresponding with 12 positions, ball cave.
Clutch pinion 4 is fixed on support 11 by fixed bolt 14.
As shown in Figure 2, in the time that driving wheel is interior wheel: free movable frame 8 and clutch pinion 4 these combinations are engaged by the gear teeth I5 of clutch pinion 4 and the gear teeth II3 of follower 2, form a freely movable entirety, due to the cooperation that ball 10 slides, the on-stream positioning action having played free movable frame 8.
In the time that driving wheel 1 rotating speed equals follower 2, driving wheel 1 and follower 2 on angular velocity in relative static conditions, thereby free movable frame 8, clutch pinion 4, clutch arm 6 and ball 10 these assembly parties all remain static, the driving wheel 1 of device turns round in the mode being independent of each other mutually with follower 2.
In the time that the rotating speed of driving wheel 1 is greater than the rotating speed of follower 2, under the positioning action of free movable frame 8 and clutch pinion 4, driving wheel 1 moves forward with respect to free movable frame 8 by the slip of ball 10, drive clutch arm 6 to move forward, now clutch pinion 4, in nonrotating state, makes clutch arm tooth engage with clutch gear teeth I5, along with the quickening of driving wheel 1 rotating speed, its power conducts to follower 2 by clutch arm 6 and clutch pinion 4, thereby reaches the object that driving wheel 1 drives follower 2 to rotate.
As shown in Figure 1, in the time that the rotating speed of driving wheel 1 is less than the rotating speed of follower 2, the positioning action combining due to free movable frame 8 and clutch pinion 4, follower 2 drives clutch pinion 4 to be slided and moved ahead by ball 10 together with free movable frame 8, clutch arm 6 is separated with clutch pinion 4, because clutch arm 6 is that clutch arm from free movable frame 8 passes through hole 9 and passes, free movable frame 8 moves ahead after certain distance and is blocked by clutch arm 6, and 8 of free movable frames move with driving wheel 1; Now, because the rotating speed of follower 2 is higher than driving wheel 1, clutch pinion 4 and free movable frame 8 are produced to thrust forward, under the stopping of clutch arm 6, can only drive clutch pinion 4 to dally, realize the effect that follower 2 departs from driving wheel 1 and rotate alone.
As shown in Figure 3,4, in the time that driving wheel is foreign steamer, owing to clutch arm 6 and ball cave 12 being fixed on all the time on driving wheel 1, gear teeth II3 is always on follower 2, the physics installation direction of the freely movable entirety that therefore free movable frame 8 forms with clutch pinion 4 and interior take turns while doing driving wheel contrary, power passes to interior wheel by foreign steamer, and both motion principles are identical.Above-mentioned interior take turns do the working procedure of driving wheel and device " from ", the state of " closing " is equally applicable to this situation.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
