In rotating shaft 10,
Double sided rack 15 also is located at the 3rd gear 3 and the 4th gear 4 between first gear 1 and second gear 2
Between, the side of double sided rack 15 is engaged with the gear 2 of first gear 1 and the 3rd simultaneously, and the opposite side of double sided rack 15 is simultaneously with second
The gear 4 of gear 2 and the 4th engages；
Chain 20 is arranged on the first sprocket wheel 5 and the second sprocket wheel 6.
Further, in addition to the first engine 24, the first engine 24 are connected with the one end of double sided rack 15, and first starts
Machine 24 drives double sided rack 15 to move back and forth.
Further, in addition to the second engine 25, the second engine 25 are connected with the other end of double sided rack 15, the first hair
The engine 25 of motivation 24 and second drives double sided rack 15 to move back and forth jointly.
Further, the first engine 24 and the second engine 25 are four-stroke engine.
Further, in addition to the first magnet 26 and the second magnet 27, the first magnet 26 are fixed on the one of double sided rack 15
End, the second magnet 27 are fixed in the frame 16 of the corresponding side of the first magnet 26.
Further, in addition to the 3rd magnet 28 and the 4th magnet 29, the 3rd magnet 28 are fixed on the another of double sided rack 15
One end, the 4th magnet 29 be fixed on in the frame 16 of 28 corresponding side of the 3rd magnet.
Further, the first magnet 26 is permanent magnet or electromagnet, and the second magnet 27 is permanent magnet or electromagnet,
Three magnet 28 are permanent magnet or electromagnet, and the 4th magnet 29 is permanent magnet or electromagnet.
Further, in addition to rocking bar 17 and banking pin 19, two banking pins 19, rocking bar 17 are fixed with double sided rack 15
One end is connected in frame 15 by revolute pair 23, and between two banking pins 19.
Further, in addition to back-moving spring 18, the one end of back-moving spring 18 are fixed in double sided rack, and back-moving spring 18 is another
One end is fixed in frame.
Further, the first unilateral bearing 11 is identical with the locked direction of the second unilateral bearing 12, the 3rd unilateral bearing 13
It is locked in opposite direction with the 4th unilateral bearing 14.
Further, the rotating shaft 10 of first rotating shaft 9 or second is connected with wheel.
By taking Fig. 1 and 2 visual angle as an example, it is assumed that the locked direction of the first unilateral bearing 11 is counterclockwise, the second unilateral bearing
12 locked direction is counterclockwise, and the locked direction of the 3rd unilateral bearing 13 is counterclockwise, the locked side of the 4th unilateral bearing 14
To be clockwise.
When double sided rack moves right in Fig. 1, the 3rd gear rotate counterclockwise so that in the outer ring of the first unilateral bearing
Enclose locked, drive first rotating shaft rotate counterclockwise；Now, the 4th gear turns clockwise, and the second unilateral bearing is in not locked
State, the rotation of the second unilateral bearing outer ring do not influence inner ring, so as to which the second rotating shaft is motionless.First rotating shaft rotate counterclockwise
The 3rd unilateral bearing inner ring rotate counterclockwise is driven simultaneously, and the inner ring rotate counterclockwise of the 3rd unilateral bearing will not drive outer ring to revolve
Turn, so as to which outer ring will not also drive chain to rotate.The long and, which is that double sided rack moves right, drives first rotating shaft to transport counterclockwise
It is dynamic.
When double sided rack is to left movement in Fig. 1, the 3rd gear turns clockwise so that the outer ring of the first unilateral bearing is suitable
Hour hands are rotated, and the first unilateral bearing inner ring will not be driven to rotate.Now, the 4th gear rotate counterclockwise, the second unilateral bearing
Outer ring drive inner ring rotate counterclockwise, inner ring drive the second rotating shaft rotate counterclockwise.Second rotating shaft drives the 4th unilateral bearing
Inner ring is inverse to turn clockwise so that the 4th unilateral bearing inner ring outer ring is locked, and inner ring drives outer ring rotate counterclockwise, and outer ring drives
Chain rotate counterclockwise, chain drives the 3rd unilateral bearing outer ring rotate counterclockwise by the first sprocket wheel, outside the 3rd unilateral bearing
It is locked to enclose inner ring, 3rd bearing inner ring drives first rotating shaft rotate counterclockwise, and first rotating shaft drives the first unilateral bearing inner ring inverse
Hour hands are rotated, and the first unilateral bearing inner ring is not had an effect power with outer ring.The long and is, double sided rack drives the to left movement
One rotating shaft counterclockwise movement.
In summary, double sided rack, all drive first rotating shaft counterclockwise movements are moved right to the left.
The effect of first gear 1, second gear 2 is auxiliary so that double sided rack stable movement.
The locked direction of first unilateral bearing 11 is counterclockwise it is meant that when the inner ring of the first unilateral bearing is fixed
When, outer ring can only turn clockwise, and counter clockwise direction outer ring can not then move.
First magnet 26 is set to permanent magnet, the second magnet 27 is set to electromagnet, utilizes the south of computer-controlled electromagnetic iron
The cyclically-varying of the pole arctic.Attraction and repulsive force are periodically produced between electromagnet and permanent magnet, promotes double sided rack past
Multiple motion.
