Abstract
A kind of linear velocity half-convergency speed mode buncher, is, in the case where input shaft end inputs a constant rotating speed, by adjusting the rotation direction of adjustment axis, to allow the corresponding rotating speed of its power output shaft one.This corresponding rotating speed is the rotation number of turns and rotation direction by adjustment axis to determine, this corresponding rotating speed can be with stepless changing.The linear velocity of chain is determined according to the rotating speed of input shaft, is connected to the expansion link of chain and only could be driven output shaft rotation around the part that output shaft does circular periphery motion in chain.It is socketed on the taper cone pulley extruding chain of power output shaft, taper surface will cause the chain link for doing circular periphery motion away from power output shaft, in the case where the linear velocity of chain is constant, the expansion link that output shaft does circular periphery motion is connected to, will be declined by the angular speed of chain drive.Similarly, when taper cone pulley departs from the motion of chain direction, the rotating speed of power output shaft will increase.Stepless speed regulation can be achieved and revolutional slip is relatively reduced.
Description
Technical field
The invention belongs to speed changer manufacturing technology field, more particularly to a kind of linear velocity half-convergency speed mode variable speed
Device.

Operation principle
Angular wheel on rotary power input shaft, power input shaft is engaged with the angular wheel on the 4th axle, and the 4th axle is rotated.
4th axle allows the 3rd axle to rotate by first gear, second gear, the second axle, the 3rd gear and the 4th gear.3rd axle and
Four axles drive the first driving chain and the second driving chain to move respectively.One end of expansion link, which is articulated with, is connected to the first driving-chain
Pole on bar and the second driving chain, pole drives expansion link to rotate.
The part for propping up 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 is moved, at this moment, vertical with the direction of motion of chain link with the axis for the expansion link that this part chain link is connected, and chain link drives
Expansion link is rotated, and imparts power to output shaft.
The expansion link being connected with not doing the chain link of circular periphery motion parts, which will be pulled, to be elongated or shortened, and is not involved in driving
The rotation of output shaft.
The thread rotary orientation of the screwed hole of first adjustable plate and the second adjustable plate is on the contrary, when rotating adjustment axis, first is adjusted
Plate and the second adjustable plate will be close to each other or remote.When the first adjustable plate and the second adjustable plate close to when, drive the first taper cone pulley
The conical surface with the first taper cone pulley is close to each other, and the taper surface of the first taper cone pulley and the second taper cone pulley extrudes 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 expansion link
Angular speed diminish, the rotating speed of power output shaft diminishes.
Conversely, when the first adjustable plate and the second adjustable plate are located remotely from each other, the rotating speed of power output shaft becomes big.
The taper of taper cone pulley is propped up with the sections inner side of chain in order to ensure chain to remain with tightly engaging for sprocket wheel
The 3rd axle and the 4th axle are held in face, the first extension spring and the second extension spring respectively, allow chain to tighten all the time.In order to ensure the steady of the second axle
Qualitative, the elongated hole of the first guide plate and the second guide plate left end limits the direction of motion of the second axle.
