Abstract
A kind of linear velocity half-convergency speed mode stepless transmission is, by adjusting the rotation direction of adjustment axis, to allow one corresponding revolving speed of its power output shaft in the case where input shaft end inputs a constant revolving speed.This corresponding revolving speed is determined by the turnning circle and rotation direction of adjustment axis, this corresponding revolving speed can be with stepless changing.The linear velocity of chain is determined according to the revolving speed of input shaft, and the telescopic rod for being connected to chain only could drive output shaft to rotate in chain around the part that output shaft does circular periphery movement.The taper cone pulley for being socketed on power output shaft squeezes chain, tapered surface will make the chain link for doing circular periphery movement far from power output shaft, in the case where the linear velocity of chain is constant, it is connected to the telescopic rod that output shaft does circular periphery movement, will be declined by the angular speed of chain drive.Similarly, when taper cone pulley is detached from the movement of chain direction, the revolving speed of power output shaft just be will increase.Stepless speed regulation and the opposite reduction of revolutional slip can be achieved.
Description
Technical field
The invention belongs to speed changer manufacturing technology fields, more particularly to a kind of linear velocity half-convergency speed mode variable speed
Device.

Working principle
Rotary power input shaft, the angular wheel on power input shaft are engaged with the angular wheel on the 4th axis, the 4th axis
Rotation.4th axis is rotated by first gear, second gear, the second axis, third gear and the 4th gear by third axis.Third axis
The first driving chain and the second driving chain is driven to move respectively with the 4th axis.One end of telescopic rod, which is articulated with, is connected to the first biography
Strut on dynamic chain and the second driving chain, strut drive telescopic rod rotation.
The part for resisting the chain of taper cone pulley is limited by the conical surface, and the chain of this part can only be done to be done centered on output shaft
Circular periphery movement, at this moment, the axis for the telescopic rod that chain link is connect with this part and the direction of motion of chain link are vertical, and chain link drives
Telescopic rod rotation, imparts power to output shaft.
The telescopic rod connecting with the chain link for not doing circular periphery motion parts will be pulled and elongate or shorten, and be not involved in driving
The rotation of output shaft.
On the contrary, when rotating adjustment axis, first is adjusted the thread rotary orientation of the threaded hole of first adjustable plate and the second adjustable plate
Plate and the second adjustable plate will be close to each other or separate.When the first adjustable plate and the second adjustable plate close to when, drive the first taper cone pulley
Close to each other with the conical surface of the first taper cone pulley, the tapered surface of the first taper cone pulley and the second taper cone pulley squeezes the first driving chain respectively
With the second driving chain the chain link radius of gyration is increased, in the case where the linear velocity of chain is constant, chain link drives telescopic rod
Angular speed become smaller, the revolving speed of power output shaft becomes smaller.
Conversely, the revolving speed of power output shaft becomes larger when the first adjustable plate and the second adjustable plate are located remotely from each other.
The taper of taper cone pulley is resisted with the sections inner side of chain with tightly engaging for sprocket wheel in order to guarantee that chain is remained
Face, the first tension spring and the second tension spring hold third axis and the 4th axis respectively, and chain is allowed to tighten always.In order to guarantee the steady of the second axis
Qualitative, the long hole of the first guide plate and the second guide plate left end limits the direction of motion of the second axis.
