The stepless speed changing mechanism has two ways, respectively gear connection and chain connection.Separately below to both sides Formula illustrates：
By the way of gear connection：
First planetary set also includes the first gear ring, and the second planetary set also includes the second gear ring, and is fixed with the first gear ring One gear, second gear is fixed with the second gear ring.
Internal tooth is equipped with first gear ring and the second gear ring, internal tooth engages with corresponding planetary gear respectively.First gear is pacified Mounted in the outside of the first gear ring, second gear is arranged on the outside of the second gear ring.Can also be on the first gear ring and the second gear ring External tooth is opened up, replaces first gear and second gear.
Further, the stepless speed changing mechanism also includes the second axle and the 3rd axle, and the second axle is provided with the 3rd gear and the Four gears, the 3rd axle are provided with the 5th gear and the 6th gear, and the 3rd gear engages with first gear, the 4th gear and the 5th tooth Wheel engagement, the 6th gear engage with second gear.
Further, the first sun gear, the first planet carrier and first no less than one group are provided with first planetary set Planetary gear, the second sun gear, the second planet carrier and the second planetary gear no less than one group are provided with second planetary set.
Further, the 3rd axle is provided with one-way clutch.
Further, the one-way clutch on the 3rd axle is arranged between the 5th gear and the 6th gear.
By the way of chain connection：

Further, first planetary set also includes the first gear ring, and the second planetary set also includes the second gear ring, the first tooth Circle is engaged with the second gear ring, and the one-way clutch is connected on the first gear ring.
The present invention principle be：
Exemplified by a manner of using gear connection：
1st, the bang path of power：
Power is input in the first planetary set by input shaft, and power is delivered to by the first planetary set respectively by first axle and first gear In second planetary set.Wherein, the process that power is transferred to the second planetary set by first gear is：Pass through first gear and the 3rd gear Engagement, then via the second axle and the 3rd axle, the second planet is delivered to engaging for second gear eventually through the 6th gear On the gear ring of group.Therefore, the power that the second planetary set is transmitted by two paths from the first planetary set, and then be sent to On output shaft, resultant moment is formed.Wherein, the effect of the 4th gear and the 5th gear is to change the transmission on the first planetary set gear ring Direction, under the collective effect of the one-way clutch on the 3rd axle, it is ensured that the rotation of the second planetary set outer ring and turning for input shaft Dynamic direction is consistent.
2nd, principle of the invention：
Because planetary reduction gear has inertia in itself, when power is input in the first planetary set by input shaft, the first planetary set exists The power can be all divided into two equal torques in any case（By setting the first sun gear, the first planet carrier, the first gear ring The number of teeth）, by the relevant connection relation in the present invention, it is applied in the second planetary set：The transmission direction of first torque is It is to be received the power of input shaft by the first sun gear and then be further conveyed to by the first sun gear with engaging for the first planet carrier On second sun gear of the second planetary set, the transmission direction of second torque is right by the power of the first sun gear reception input shaft It is delivered to again by each gear on the second gear ring of the second planetary set by the connection of the first sun gear and the first gear ring afterwards.This Sample, just cause collective effect power of the output shaft by two torque.
When output shaft is reached the maximum moment that can be generated by the self structure of the present invention by resistance torque, the first tooth Circle and the second gear ring stop operating.
When output shaft is by resistance, and resistance torque is less than the maximum moment that can be generated by the self structure of the present invention When, the first gear ring in the first planetary set produces the rotation opposite with input shaft under the drive of first gear, by the second axle and Gap bridge tooth on 3rd axle --- the 4th gear and the 5th gear are transferred force in the second gear of the second planetary set, so as to band The second gear ring rotation of dynamic second planetary set, and the direction of rotation of the second gear ring gives the fortune of the second sun gear with first axle Dynamic direction of rotation is consistent, and due to the principle of planetary reduction gear in itself, at this moment, the speed of output shaft is due to by two identical steerings Torque accumulative action, and then add the torque of output shaft, and the system of the present invention is special due to planetary reduction gear Mechanism, the torque and speed of output can voluntarily be adjusted according to the change of external resistance square at any time, so as to realize perfection Mechanical intelligence formula variable speed or bending moment.
3rd, passed a bridge tooth --- the effect of the 4th gear and the 5th gear in the present invention：
Because the rotation direction of planet carrier and gear ring in planetary set is on the contrary, gap bridge tooth then the direction of transfer to adjusting force and is put The loss of torque is put, so as to ensure that the second gear ring of the second planetary set will not be caused because of output shaft by the influence of extraneous torque Invert and allow power to waste in vain, and then optimal transmission effect.
4th, the effect of one-way clutch：
One-way clutch is to prevent the system of the present invention from, because being acted on by external force, making the torque of power output in systems Voluntarily digest, produce internal rotation.
Using chain connection by the way of with coupled using gear by the way of it is similar in principle, it only difference is that： It is to change to turn to using chain by the way of chain connection, is to use gap bridge tooth --- the 4th tooth by the way of gear connection Wheel and the 5th gear turn to change.
