(5) embodiment:
A kind of satellite tooth stepless speed variator based on variable crank length crankrocker mechanism of the utility model, it is made up of crankrocker mechanism I, clamping type satellite tooth freewheel II and rotor linkage mechanism III three parts of continuous variable crank length.
By rotor linkage mechanism III the crankrocker mechanism I of continuous variable crank length is connected with clamping type satellite tooth freewheel II, and realizes that the utility model stepless shift function is feature of the present utility model place.
For clamping type satellite tooth freewheel II, in its working stroke, the angular velocity of the outer gripping surface 25 of freewheel and loose boss 23 angular velocity are in the same way, and angular velocity more than or equal to loose boss 23, the outer gripping surface 25 of freewheel this moment and clamper body 21 be because of friction self-locking is synchronized with the movement, and via satellite tooth 22 with transmission of torque to loose boss 23.At the inoperative stroke, the angular velocity of the outer gripping surface 25 of freewheel and loose boss 23 angular velocity are oppositely or less than the angular velocity of loose boss 23, outer gripping surface 25 of freewheel and the 21 relatively independent motions of clamper body, transmission of power separation.Can realize the unidirectional transmission of clamping type satellite tooth freewheel II and the reciprocally swinging of the outer gripping surface 25 of freewheel is converted into the rotation of loose boss 23 based on above-mentioned principle.
When control motor 15 did not rotate, bent axle 11 immobilized with the relative rotation of crank pin 12, and bent axle 11 directly drives crank pin 12 and rotates.The rotation of crank pin 12 will cause the eccentric rotary of rotor 31, and the eccentric rotary of rotor 31 drives clamping type satellite tooth freewheel II by driving lever 32 and follower lever 33 and do reciprocal swing on free wheel shaft 44.According to above-mentioned clamping type satellite tooth freewheel II the reciprocally swinging of the outer gripping surface 25 of freewheel is converted into the function of the rotation of loose boss 23, has realized the transmission of power of rotating to loose boss 23 by the rotation of bent axle 11.Loose boss 23 is connected by the flat key (not shown) with free wheel shaft 44 and rotates with speed, and free wheel shaft 44 ends are equipped with gear of output end 42, and the engagement by gear of output end 42 promptly drives output shaft 43 and rotates.This moment, the utility model bent axle 11 was certain steady state value to the velocity ratio between the output shaft 43.
When needs are changed the utility model bent axle 11 to the gear ratio value between the output shaft 43, only need the certain corner of control motor 15 outputs, drive crank pin 12 relative bent axles 11 and turn over an angle, the central shaft of the cylinder shank 121 on the crank pin 12 and the distance between bent axle 11 centers of rotation change at this moment, and will cause that the orbital radius of rotor 31 eccentric rotary changes.If the output corner of therefore continuous change control motor 15, then continuous variation will take place in the distance between the central shaft of the cylinder shank 121 on the crank pin 12 and bent axle 11 centers of rotation, and the orbital radius of rotor 31 eccentric rotary also will take place to change continuously.The angular velocity that this moment, clamping type satellite tooth freewheel II did reciprocal swing on free wheel shaft 44 also will change, and then the rotating speed of loose boss 23, free wheel shaft 44, output shaft 43 all changes.Be that bent axle 11 obtains adjusting to the velocity ratio between the output shaft 43.Thereby 43 transmission of power and the stepless adjustment of velocity ratio under 15 controls of control motor have been realized from bent axle 11 to output shaft.
