44 only rotations make first end face gear 42 be rotated with 43 synchronous backward of second end face gear, so that front side without revolving round the sun
Rotation axis 2 and 3 synchronous backward of rear side rotation axis rotate.
When rotation axis 2 and rear side rotation axis 3 synchronously rotate in same direction on front side of needing, led to using controller 64 into coil 731
Positive electric current, makes spool 71 move right, so as to drive connector sleeve 61 and lock sleeve 62 to slide to the right.The insertion of connector sleeve 61 the
In one annular groove 422, the second fixture block 612 is with being placed in the second card slot 423, using connector sleeve 61 by second(-)motion shaft 41 and second
Face gear 43 is fixed.Lock sleeve 62 is inserted into the second groove 12, and the 4th fixture block 622 departs from from the 4th card slot 433, makes second
Face gear 43 is freely rotated.Then starting servomotor 5 makes it drive first end face gear 42 to rotate, and planetary gear 44 is only public
Then rotation does not occur, first end face gear 42 is synchronously rotate in same direction with second end face gear 43, so that front side rotation axis 2
Synchronously rotate in same direction with rear side rotation axis 3.
When only needing the front side rotation of rotation axis 2, stop being powered into coil 731 using controller 64, spool 71 is in spring
The centre position of guide rod 72 is slid under the action of 721, so as to drive connector sleeve 61 and lock sleeve 62 to slide into it and each slide
The centre position of track, is freely rotated second(-)motion shaft 41, is fixed second end face gear 43 using lock sleeve 62.So
Starting servomotor 5 afterwards makes it drive first end face gear 42 to rotate, and rotation while revolution of planetary gear 44, makes first end
Face gear 42 rotates, so that front side rotation axis 2 rotates, and rear side rotation axis 3 stops.
This specific embodiment is only explanation of the invention, it is not limitation of the present invention, people in the art
Member as needed can make the present embodiment the modification of no creative contribution after this specification is read, but as long as at this
All protected in the right of invention be subject to Patent Law.
