The inner ring of clutch 601 drives connected gear 603 synchronous axial system, two gears 603 and power by connecting bearing 602
Output gear 2 is meshed, and the freely rotatable direction of said two freewheel clutch 601 is identical, so that tooth bar 5 moves reciprocatingly
Time, by power by gear train unidirectional delivery to power output gear 2.
It is more than the basic embodiment of the present invention, can further be improved, optimize and limit on the basis of above:
As, described fixed support 1 is arranged with in parallel two fixing bars 101, between two fixing bars 101, is provided with motor bin
102, described regulation motor is arranged in this motor bin 102；
And for example, the output shaft of described regulation motor is engaged, to impart power to driving screw rod 404 by a gear train 405
Drive screw rod 404；
And for example, described crank shelf 401 includes a flat board 4011 and is arranged on flat board 4011 two ends and for setting up two leading screws 402
Two pieces of support plates 4012, and one end of flat board 4011 has extension 4013, and described driving screw rod 404 is positioned at extension 4013
On, the end of two leading screws 402 reaches the top of extension 4013, and by two turbines II 4014 all with driving screw rod
404 engagements；
Further, go back level frame between described two pieces of support plates 4012 and be provided with two guide rods for assisting displacement block 403 balance
4015；
For another example, described displacement block 403 and tooth bar 5 being provided with bearing pin 8, transfers with two bearing pins 8 respectively in the two ends of connecting rod 3；
For another example, described fixed support 1 being provided with a cross bar 103, the bottom of cross bar 103 is provided with chute, and described tooth bar 5 slides
It is arranged in this chute；Described power output gear 2 and two gears 603 engaged are respectively positioned on cross bar 103；
Further, set up by two support plates below described cross bar 103 and have a slide bar 104, and be provided with on support plate for tooth bar 5
The groove passed, the bottom of tooth bar 5 is provided with the bearing pin 8 hinged for connecting rod 3, and this bearing pin 8 is located on slide bar 104；
Finally, travelling gear 9 it is engaged with between said two gear 603 and power output gear 2.
1 and 2 the present invention will be described in detail below in conjunction with the accompanying drawings, and as seen from the figure, the present invention is mainly by with lower part structure
Become: for supporting the fixed support 1 of each main parts size, naturally it is also possible to be fixing cabinet etc, write music as variable length
The crank shelf 401 of handle skeleton, for changing two leading screws 402 and displacement block 403, the spiral of two leading screws 402 of crank length
In opposite direction.Have, in displacement block 403, the screw thread coordinated with two leading screws 402, when two leading screws 402 rotate, conjugate block 403
Put and can move to crank shelf 401 edge from crank shelf 401 center of rotation axle, to reach to change the purpose of crank length.Crank shelf
Having the motor bin 102 for installing secured adjusted motor below 401, it is cavity structure, interior installation secured adjusted motor, motor
Rear end, storehouse 102 is crank rotary shaft, inputs for rotary power；On crank rotary shaft cylindrical, brush ring is installed, is used for regulating
The input of motor power.The output shaft of regulation motor is driven by gear train 405 and drives screw rod 404, and then drives two turbines
II 4014 and two leading screws 402.Because two turbines II 4014 are driven by same driving screw rod 404, therefore can keep same
Step rotates, and then keeps two leading screw 402 synchronous rotaries；
By central shaft and the tooth bar 5 of the displacement block 403 on connecting rod 3 connecting crank, promotion tooth bar 5 is done round by the rotation of crank
Linear movement.Two edges of tooth bar 5 all have teeth, two freewheel clutch 601 outer rings to be teeth, respectively with tooth bar 5 liang
The teeth at edge are ratcheting.Two freewheel clutch 601 inner ring fixed connection shafts hold 602, after connection bearing 602 passes cross bar 103
Other end fixed installation gear 603.The freely rotatable direction of two freewheel clutches 601 is identical (to be time seen from above
Time counterclockwise, outer ring is freely rotatable relative to inner ring, as a example by time clockwise, outer ring promotes inner ring to rotate), when tooth bar 5 travels forward,
Drive freewheel clutch 601 outer ring to rotate clockwise, and then drive connection bearing 602 and gear 603 to rotate clockwise, work as tooth bar
During 5 rearward movement, freewheel clutch 601 is driven to rotate counterclockwise, on the rotation connecting bearing 602 and gear 603 without impact.Cause
5 one back and forth movements of this tooth bar, only driven gear 603 rotates clockwise, to gear 603 nothing when simply tooth bar 5 travels forward
Impact, during rearward movement, driven gear 603 rotates clockwise.Gear 603 rotate clockwise band nutating gear, and then drive
Power output gear 2 only rotates to a direction, it is achieved that the rotation purpose in one direction of output.
From the above, it can be seen that the transmission between each parts is rigidity transmission, Large-torsion transmisson therefore can be done.Speed change
During, when conjugating block 403 central shaft and crank center of rotation axle overlaps, outfan velocity of rotation is zero.When displacement block 403
When gradually being moved to crank shelf 401 edge by center, outfan velocity of rotation gradually accelerates, to outfan velocity of rotation during edge
The fastest, the rotating speed of transmission output can be made in theory by the size adjusting freewheel clutch 601 and its rear end gear 603
Relative input end is the fastest.In actual use, can be using regulating motor and the motor bin part as engine flywheel, to subtract
Few gross weight.Identical tooth bar 5, freewheel clutch 601 can be used in vertical both direction, connect bearing 602, gear 603
Structure makes outfan stabilization of speed.The gross weight that can increase gear of output end 603 makes output speed stable.
Technical scheme cited by the present invention and embodiment non-limiting, with the technical scheme cited by the present invention and
Embodiment equivalent or effect same approach are all in the range of the present invention is protected.
