Abstract
The invention belongs to the field of mechanical stepless transmission and includes a harmonic gear-driving stepless transmission, which is composed of a driving shaft, a driven shaft, a rigid gear, a flexible gear, a wave generator and a roller; the flexible gear can make axial movement relative to the rigid gear, the teeth of the flexible gear are composite teeth, which are composed of two branch teeth. When the flexible gear makes axial movement relative to the rigid gear, the angle between the two branch teeth of the composite teeth and the tooth thickness are variable, when the rigid gear keeps stationary and the driving shaft actuates the wave generator to rotate, the wave generator forces the flexible gear to generate continuous elastic deformation by the roller, and the tooth thickness of the composite teeth of the flexible gear also changes with the deformation of the flexible gear; because the tooth thickness or the width between the teeth keeps variable when the teeth number of the rigid gear is fixed, although the teeth number ratio of the flexible gear and the rigid gear keeps unchanged, the arc length passing the nodal circle is variable, and the stepless transmission can be realized so long as the flexible gear makes axial movement relative to the rigid gear.
Description
Technical field
The invention belongs to the mechanical stepless transmission field.
Background technique
In the mechanical stepless transmission field, existing three major types: i.e. (1) fluid power class; (2) electromagnetism class; (3) friction class.More than three classes all be to utilize frictional force in essence, so efficient is low.
The objective of the invention is: design and a kind ofly can overcome above-mentioned shortcoming, can realize rigidly connected mechanical variable speed system, realize the target that people dream of for a long time in the mechanical transmission fields.
Summary of the invention
The invention discloses a kind of harmonic teeth-driving stage-less speed variator, it is by driving shaft, driven shaft, just take turns, flexbile gear, wave-generator and roller constitute, flexbile gear can be relative to firm wheel shaft to moving, just wheel is conical inner gear, flexbile gear is a cone gear, because its transverse tooth thickness or space width are variable under the certain situation of firm tooth number, for making flexbile gear relative to firm wheel shaft flexbile gear and firm wheel good engagement when moving, the tooth of flexbile gear is a composite teeth, composite teeth is made of two sub-teeth, flexbile gear relative to just wheel shaft when moving, two sub-bottom angles of composite teeth, transverse tooth thickness is variable, the teeth groove of just having taken turns in the engagement place can hold a composite teeth of flexbile gear, in addition, the also available annular toothed chain of flexbile gear substitutes, the tooth of annular toothed chain is a composite teeth, composite teeth is made of two sub-teeth, annular toothed chain relative to just wheel shaft when moving, two sub-bottom angles of composite teeth, transverse tooth thickness is variable, wave-generator is that the cross section is the drum cam of the constant major and minor axis radius gradual change of oval girth, it is characterized in that: flexbile gear can be relative to just wheel shaft to moving, flexbile gear or annular toothed chain relative to firm wheel shaft when moving, the transverse tooth thickness of composite teeth is variable, and the radius of wave-generator is variable.
Its working principle is: when firm wheel motionless, the firm gear teeth of compound gear ratio of flexbile gear are few, the firm relatively wheel shaft of flexbile gear is when motionless, identical with common Harmonic Gears principle, when driving shaft drives the wave-generator rotation, when wave-generator rotates in flexbile gear, force flexbile gear to produce continuous resiliently deformable, the continuous rotation of wave-generator at this moment, just make the flexbile gear tooth engaging-in-mesh-nibble out-throw off these four kinds of cycle of states and back and forth constantly change original separately engagement, flexbile gear tooth and the just gear teeth in pitch circle place engagement process just as the annulus of two pure rolling, both are in any moment, the arc length that turns on pitch circle must equate, tooth lacks on pitch circumference because flexbile gear is than just taking turns, so flexbile gear in engagement process, just must relatively just be taken turns the angular displacement that turns over few tooth tooth pitch, this angular displacement is the rotation of output shaft just, thereby has realized the purpose of slowing down.
When firm wheel motionless, flexbile gear relative to just wheel shaft to moving, and when driving shaft drives the wave-generator rotation, wave-generator forces flexbile gear to produce continuous resiliently deformable by roller, though its transverse tooth thickness or space width are variable under the certain situation of firm tooth number, because the composite teeth of flexbile gear is with the deformation transverse tooth thickness of flexbile gear also respective change, make the good engagement of firm wheel and flexbile gear, flexbile gear and just wheel in pitch circle place engagement process just as the annulus of two pure rolling, both are in any moment, the arc length that turns on pitch circle must equate, though flexbile gear is constant with the gear ratio of just having taken turns, but the arc length that turns on pitch circle becomes, as long as make flexbile gear just can realize stepless change relative to just wheel shaft to moving.
Beneficial effect of the present invention shows: if be applied to automobile, can save the trouble of gearshift, make speed change more convenient, efficient improves, no slippage.Though, the fluid power class; The electromagnetism class; The friction class also can satisfy requirement like this, still, its Economy, reliability, and transmission efficiency but can't be equal to the present invention program.
