Abstract
The invention discloses a polyhedral swing movable tooth transmission device. An input shaft shock machine is arranged in a manner of being concentric with an output shaft rack and a central internal gear, the central internal gear is fixedly connected with an engine body base, the output shaft rack is provided with a movable tooth pin, swing movable teeth are arranged on the movable tooth pin in a sleeving manner and meanwhile contacted with the tooth profile of the input shaft shock machine and the tooth profile of the central internal gear; the tooth profile curve of the input shaft shock machine is a polyhedral profile curve or an equidistant curve of the same. The polyhedral profile curve is the polyhedral curve or the equidistant curve of the same generated according to the polyhedral forming equation. According to the polyhedral swing movable tooth transmission device, the swing movable tooth and the movable tooth pin are employed to replace traditional eccentric or steel ball movable tooth, so that the processing difficulty is greatly reduced, size and precision are ensured better, wear caused by rolling and slipping friction is also greatly reduced, the transmission is more stable due to the polyhedral curve transition, and thus the polyhedral swing movable tooth transmission device becomes a transmission element with good transmission performance.
Description
Technical field
The present invention relates to the driving mechanism technical field, is a kind of Polyhedral swing movable gear driving device specifically.
Background technique
Various reducing gears are widely used in producing and equipment manufacture, Oscillating Tooth Gear Reducer is widely adopted as the reducing gear with advantages such as compact structure, transmission are stable, reduction speed ratio is large, but traditional mobile oscillating tooth oscillating tooth is because the engagement pair wear problem causes using scope to be limited to some extent.
Summary of the invention
The deficiency existed in order to overcome above-mentioned technology, technical problem to be solved by this invention is to provide a kind of Polyhedral swing movable gear driving device.
Technological scheme of the present invention is: the Polyhedral swing movable gear driving device, comprise input shaft shock wave device, output shaft frame, oscillating tooth pin, wobble gear, Central inner gear, it is characterized in that: the input shaft shock wave device is concentric installation with output shaft frame, Central inner gear, Central inner gear is fixedly connected with the body base, the oscillating tooth pin is installed on the output shaft frame, and wobble gear is sleeved on the oscillating tooth pin and with the profile flank profil of input shaft shock wave device and the flank profil of Central inner gear, contacts simultaneously; The profile tooth curve of described input shaft shock wave device is Polyhedral profile curve or its equidistant curve.
Described Polyhedral profile curve refers to by Polyhedral and forms Polyhedral curve or its equidistant curve that equation generates.
The tooth curve of described Central inner gear is to using the input shaft shock wave device as shock wave device, and output shaft frame, oscillating tooth pin are as frame, and wobble gear is as the external frame envelope curver of the formed wobble gear of oscillating tooth motion of oscillating tooth.
Advantage of the present invention is: the present invention adopts wobble gear and oscillating tooth pin to substitute traditional bias or steel ball moving teeth, make the processing technology difficulty greatly reduce, size and precision better guarantee, the wearing and tearing that slide rolling friction causes also reduce greatly, the curve transition of Polyhedral also makes transmission more steady, and these characteristics make the Polyhedral Swing Movable Teeth Drive become the good volume transmission component of a kind of transmission performance.

Embodiment
Now by reference to the accompanying drawings, technology contents of the present invention is described further.
As shown in Fig. 1-7, input shaft shock wave device 1 is concentric installation with output shaft frame 2, Central inner gear 5, Central inner gear 5 is fixedly connected with body base 6, oscillating tooth pin 3 is installed on output shaft frame 2, and wobble gear 4 is sleeved on oscillating tooth pin 3 and with the profile flank profil of input shaft shock wave device 1, contacts with the flank profil of Central inner gear 5 simultaneously; The profile tooth curve of described input shaft shock wave device 1 is Polyhedral profile curve or its equidistant curve.
Described Polyhedral profile curve refers to by Polyhedral and forms Polyhedral curve or its equidistant curve that equation generates.
The tooth curve of described Central inner gear 5 is to using input shaft shock wave device 1 as shock wave device, and output shaft frame 2, oscillating tooth pin 3 are as frame, and wobble gear 4 is as the external frame envelope curver of the formed wobble gear 4 of oscillating tooth motion of oscillating tooth.
In order better to understand Polyhedral profile curve, now in conjunction with Fig. 8, further illustrate as follows:
When several m are even number face to face, first with odd number summit vector
The terminal of ∈ [1,3,5,, m-1] is the center of circle, with
For symmetry axis, as radius, be that r, central angle are to the vector outside
The roundlet segmental arc; Again with even number summit vector
Terminal be the center of circle, with vector
For symmetry axis, to vector, tossing about as radius is that R, central angle are
The great circle segmental arc; So can be smoothly connected each other the non-grade of symmetry rule face shape formed by m section circular arc and be altogether unjustifiable round, n=m/2.
When several m were odd number face to face, first terminal of take its m summit vector was the center of circle, with vector
For symmetry axis, as radius, be that r, central angle are to the vector outside
The roundlet segmental arc; Again with m summit vector
∈ [1,3,5,, m] terminal is the center of circle, with vector
For symmetry axis, toss about and make radius to vector
, central angle is
The great circle segmental arc; Non-round of the capable face shape uniform thickness that so can form, be smoothly connected each other by 2m section circular arc (distance between any two parallel tangentss equates), n=m.
In this example, be tetrahedron, the shock wave number of teeth is 4, and the oscillating tooth number is 6, and the central gear number of teeth is 8, and velocity ratio is i=1.5.
