Tooth, the second cone tooth, triconodont, the 4th cone tooth, the 5th cone tooth and the 6th cone tooth band moving gear rotation rotation, when gear rotary course
In, according to the interaction of power, gear ring can pass to third through third axis to one reactive torque T1 of gear, reactive torque T1 and consolidate
Fixed board, then third fixed plate has a movement tendency opposite with input shaft direction of rotation;Input shaft passes through second simultaneously
Ring set is threadedly engaged with the 4th ring set, will generate driving effect to the 4th ring set;Originally the 4th ring set is by solid from third
Fixed board passes to the reactive torque T1 of third ring set, and the pressure by piston ring groove internal high-pressure gas in the axial direction,
Reactive torque of the resistance torque T 2 that mesohigh gas pressure of the present invention is driven the 4th ring set by the second ring set less than the 4th ring set
T1, so Fourth Ring cuff piston ring is moved along axis and compressing high pressure gas under the driving of the second ring set.Simultaneously in list
To under the action of clutch ring, third fixed plate be will be unable to along the rotation opposite with input shaft direction of rotation, so third fixed plate
It is relatively fixed;Gear rotation status is only rotation at this time;The gear of rotation drives output shaft rotation through gear ring and disk again.It is rising
In stage beginning, since the distance of driving conical tooth shaft line to gear ring inner headed face is 4 times of distance of Gear axis to gear ring inner headed face,
So gear can transmit biggish torque, be conducive to the starting starting rotation of the output shaft of speed changer in this way.
In the case where output shaft Rotating with Uniform and constant load, reactive torque T1 is constant always.
The stage for just needing to obtain larger output revolving speed after the speed changer transition complete startup stage for needing high torque,
The rotation that continues in the stage of transition, input shaft will drive the second ring set and continue to rotate;The rotation that continues of second ring set will drive work
Plug ring continued compression high pressure gas;Since third fixed plate has a reactive torque always, as piston ring continued compression is high
It calms the anger body, the resistance torque T 2 that high-pressure gas pressure is driven the 4th ring set by the second ring set is also with increase;When resistance torque T 2 is big
When the reactive torque T1 of third fixed plate, the 4th ring set will not continue compressing high pressure gas, and driven and revolve by the second ring set
Turn, and then third ring set drives the rotation of the first ring set, then third fixed plate, which is entered axis, drives rotation, gear generates public at this time
Transhipment is dynamic, and revolution motion turns gear ring faster;In the case where input shaft rotating speed is constant, gear ring, which is realized, subtracts torsion speedup.Revolution
The generation of movement is triggered with the accumulation of high pressure gas decrement, so revolving speed of the generation of revolution motion to input shaft
The influence very little of pulsation reduces impact of the shift to dynamical system, extends the service life of a whole set of transmission system.T2 and reactive torque
The conjunction torque of T1 is T3, and the revolution of gear ring is determined by T3.
The differential gear transmissions of the driving cone tooth, two the first cone teeth and the second cone tooth composition that design in the present invention can be protected
The revolution motion of card gear does not influence the spinning motion of gear.
When bindiny mechanism stops working, under the reset response of scroll spring, the second ring flat-plate can drive second
Ring set direction rotates, and then the 4th ring set can be made to reset in the case where being threadedly engaged.In bindiny mechanism, this scroll spring almost only
It participates in compression and resets, hardly transmitting torque, therefore the service life of scroll spring can be very long, to make the use of bindiny mechanism
Service life extends.
Relative to traditional transmission technology, the beneficial effect of variable speed drives is realized in the present invention using bindiny mechanism
It is: realizes speed changing effect using simple structure, simultaneously because stirring power is realizing when being compressed to the limit by air pressure, so dialling
The formation of power is realization step by step, and when stirring power and being greater than resistance, bindiny mechanism side can drive the first ring set to revolve
Turn, such design will not generate physics impact failure in the moment of shift speed change, thus substantially prolong making for speed changer
Use the service life;The present invention makes gear rotation with other engaging for tooth of cone using driving cone tooth, realizes the transmitting of high torque, in addition
Gear is set to revolve around gear ring under the effect that the shift of connection structure raises speed, it is real under the double effects of gear rotation and revolution
The transmitting of larger revolving speed is showed;The configuration of the present invention is simple has preferable using effect.

And the pressure by 45 internal high-pressure gas of piston ring groove in the axial direction, mesohigh gas pressure of the present invention is to the 4th ring set
The 41 resistance torque Ts 2 driven by the second ring set 31 less than the 4th ring set 41 reactive torque T1, so in the driving of the second ring set 31
Under, the 4th ring set 41 drives piston ring 43 to move simultaneously compressing high pressure gas along axis.Simultaneously under the action of one-way clutch ring 6,
Third fixed plate 10 will be unable to along the rotation opposite with 2 direction of rotation of input shaft, so third fixed plate 10 is relatively fixed;At this time
16 rotation status of gear is only rotation;The gear 16 of rotation drives output shaft 4 to rotate through gear ring 17 and disk 18 again.In starting rank
Duan Zhong, since the distance of driving cone 22 axis of tooth to 17 inner headed face of gear ring is distance of 16 axis of gear to 17 inner headed face of gear ring
4 times, then gear 16 can transmit biggish torque, be conducive to the starting starting rotation of the output shaft 4 of speed changer in this way.
In Figure 16 shown in (a), in the case where 4 Rotating with Uniform of output shaft and constant load, reactive torque T1 is always not
Become.
The stage for just needing to obtain larger output revolving speed after the speed changer transition complete startup stage for needing high torque,
The rotation that continues in the stage of transition, input shaft 2 will drive the second ring set 31 and continue to rotate;The rotation that continues of second ring set 31 can band
43 continued compression high pressure gas of piston ring;In Figure 16 shown in (b), because there is a reversed torsion always in third fixed plate 10
Square, with 43 continued compression high pressure gas of piston ring, the resistance that high-pressure gas pressure is driven the 4th ring set 41 by the second ring set 31
Torque T 2 is also with increase;When hindering torque T 2 and being greater than the reactive torque T1 of third fixed plate 10, the 4th ring set 41 will not be after
Continuous compressing high pressure gas, and driven and rotate by the second ring set 31, and then third ring set 33 drives the rotation of the first ring set 5, then the
Three fixed plates 10 are entered axis 2 and drive rotation, and gear 16 generates revolution motion at this time, and revolution motion makes 17 turns of gear ring faster;
In the case where 2 revolving speed of input shaft is constant, gear ring 17, which is realized, subtracts torsion speedup.The generation of revolution motion is with high pressure gas pressure
The accumulation of contracting amount and trigger, so influence very little of the generation of revolution motion to the speed ripple of input shaft 2, reduce shift pair
The impact of dynamical system extends the service life of a whole set of transmission system.In Figure 16 shown in (c), the conjunction of T2 and reactive torque T1 are turned round
Square is T3, and the revolution of gear ring 17 is determined by T3.
The differential gearing 16 that 22, two first, the tooth cone teeth 23 of driving cone and the second cone tooth 24 designed in the present invention form passes
Kinetic energy enough guarantees that the revolution motion of gear 16 does not influence the spinning motion of gear 16.
When bindiny mechanism 3 stops working, under the reset response of scroll spring 32, the second ring flat-plate 47 can be driven
Second ring set, 31 direction rotates, and then the 4th ring set 41 can be made to reset in the case where being threadedly engaged.In bindiny mechanism 3, this scrollwork
Spring 32 is almost only involved in compression and reset, hardly transmitting torque, therefore the service life of scroll spring 32 can be very long, to make
The service life of bindiny mechanism 3 extends.
In conclusion main beneficial effect of the invention is: realizing variable speed drives using bindiny mechanism 3 in the present invention
Beneficial effect is: speed changing effect is realized using simple structure, simultaneously because stirring power is realization when being compressed to the limit by air pressure
, so the formation for stirring power is realization step by step, when stirring power and being greater than resistance, 3 side of bindiny mechanism can be driven
The rotation of first ring set 5, such design will not generate physics impact failure in the moment of shift speed change, thus substantially prolong
The service life of speed changer;The present invention makes 16 rotation of gear with other engaging for tooth of cone using driving cone tooth 22, realizes larger
The transmitting of torque, in addition connection structure shift raise speed effect under make gear 16 around gear ring 17 revolve, gear 16 oneself
Turn and the double effects of revolution under realize the transmitting of larger revolving speed;The configuration of the present invention is simple has preferable using effect.
