Internal gear is to install with one heart, and Central inner gear is fixing with body base to be connected, and output shaft frame is provided with oscillating tooth pin, swings
Oscillating tooth be sleeved on oscillating tooth pin and simultaneously with profile flank profil and the profile contact of Central inner gear of power shaft shock wave device；Described
The profile tooth curve of power shaft shock wave device is high-order denatured elliptic surface curve or its equidistant curve.
Described high-order denatured elliptic surface curve refers to form, by high-order denatured ellipse, the high-order denatured ellipse that equation generates
Curve or its equidistant curve.
The tooth curve of described Central inner gear is using power shaft shock wave device as shock wave device, output shaft frame, oscillating tooth post
Selling as frame, swing movable gear moves as the oscillating tooth of oscillating tooth the outline envelope curve of the swing movable gear formed.
Advantages of the present invention: the present invention uses swing movable gear and oscillating tooth pin to substitute traditional bias or steel ball moving teeth, makes
Processing technique difficulty is substantially reduced, and size more preferably ensures with precision, and the abrasion that slide rolling friction causes is greatly reduced；Employing high-order becomes

Detailed description of the invention
In conjunction with accompanying drawing, the technology contents of the present invention is described further.
As shown in figs. 1-7, power shaft shock wave device 1 and output shaft frame 2, Central inner gear 5 are concentric installation, center internal tooth
Wheel 5 is fixing with body base 6 to be connected, and output shaft frame 2 is provided with oscillating tooth pin 3, and swing movable gear 4 is sleeved on oscillating tooth pin 3
Upper and simultaneously with profile flank profil and the profile contact of Central inner gear 5 of power shaft shock wave device 1；Described power shaft shock wave device 1
Profile tooth curve is high-order denatured elliptic surface curve or its equidistant curve.
Described high-order denatured elliptic surface curve refers to form, by high-order denatured ellipse, the high-order denatured ellipse that equation generates
Curve or its equidistant curve.
The tooth curve of described Central inner gear 5 is using power shaft shock wave device 1 as shock wave device, output shaft frame 2, oscillating tooth
Pin 3 is as frame, and swing movable gear 4 moves as the oscillating tooth of oscillating tooth the outline envelope curve of the swing movable gear 4 formed.
In order to be best understood from high-order denatured elliptic surface curve, now it is further described below:
If it is oval that common single order ellipse is called base, in holding corresponding point on the premise of footpath is constant, the pole oval by base
AngleIt is adjusted to new oval polar angle, the most availableRank high-order is oval. and deformed ellipse is by base
Ellipse existsPlace's segmentation, willBy degeneration coefficientIt is adjusted to deformed ellipse；WillIt is adjusted to deformed ellipse, the polar angle changing value making this section is, become the most accordingly
Property coefficientWithRelation be (WithValue be not limited to integer)
(1)
Oval and the generating principle of deformed ellipse in conjunction with high-order, by the polar angle change in oval for the high-order cycleBeing divided into two sections, every section all carries out angle adjustment by degeneration coefficient, and the degeneration coefficient making two sections isWith, and
Make its polar angle follow following relation, be the formation of high-order denatured oval
(2)
By formula (2) it can be seen thatWithStill meet formula (1)
By oval formation mechanism, on the basis of base ellipse polar equation expression formula, high-order can be respectively obtained oval
Polar equation formula with deformed ellipse
(3)
(4)
In formula:Oval eccentricity；A is oval major axis radius.Time, it is oval that high-order ellipse just becomes base. whenTime,, two sections of curve shapes of deformed ellipse are identical, are also reduced to base oval. can obtain high according to formula (3), formula (4)
Deformed ellipse polar equation expression formula of two sections of curves within a cycle in rank is
This example is second order deformed ellipse A=120mm, m=2, n=2, k=0.1, ZH=4, ZG=6, ZK=2, i=1.5.
