Abstract
The invention discloses a sleeve oscillating-teeth transmission device with high-order ellipse. The sleeve oscillating-teeth transmission device is characterized in that an input-shaft shock-wave device, an output-shaft rack and a central inner gear are concentrically arranged; the central inner gear is fixedly connected with a base of a machine body; the output-shaft rack is provided with oscillating-teeth column pins; sleeve oscillating teeth are sheathed on the oscillating-teeth column pins and simultaneously are contacted with molded-surface teeth profiles of the input-shaft shock-wave device and the molded surface tooth profile of the central inner gear. The sleeve oscillating-teeth transmission device disclosed by the invention has the advantages that the sleeve oscillating teeth and the oscillating-teeth column pins are adopted for replacing the traditional eccentric or steel-ball oscillating teeth, the contact of the sleeve oscillating teeth and the central inner gear and the contact of the oscillating-teeth column pins and an outer gear ring of a shock-wave device are in the sliding-rolling meshing form, so that the bearing capability and the transmission efficiency of a meshing pair are improved, so that the processing process becomes simple, and the accuracy is easily guaranteed; due to the curve transition of the high-order ellipse, the transmission is stable; due to the characteristics, the sleeve oscillating teeth transmission with the high-order ellipse becomes a transmission element with good transmission performance.
Description
Technical field
The present invention relates to the driving mechanism technical field, is the oval movable sleeve tooth transmission device of a kind of high-order 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 oscillating tooth is because difficulty of processing is large, and the reasons such as complex process are causing 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 are to provide the oval movable sleeve tooth transmission device of a kind of high-order.
Technological scheme of the present invention is: the oval movable sleeve tooth transmission device of high-order, comprise input shaft shock wave device, output shaft frame, oscillating tooth pin, movable sleeve tooth, 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 movable sleeve tooth is sleeved on the oscillating tooth pin and with the profile flank profil of input shaft shock wave device, contacts with Central inner gear profile flank profil simultaneously.
The tooth curve of described input shaft shock wave device is
Or its equidistant curve, in formula,
For the oval eccentric rate, oval major semi axis is
,
,
For angle becomes parameter,
The number of teeth cogged for the input shaft shock wave device,
>=1 and be integer.
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 be as frame, and movable sleeve tooth is as oscillating tooth
The external frame envelope curver of the formed movable sleeve tooth of the poor oscillating tooth motion of tooth.
Advantage of the present invention is: the present invention adopts movable sleeve tooth and oscillating tooth pin to substitute traditional bias or steel ball moving teeth, movable sleeve tooth contacts with the shock wave device external toothing as sliding and rolls bearing capacity and the transmission efficiency raising that mesh form makes engagement pair with Central inner gear, oscillating tooth pin, make processing technology become simple and be easy to guarantee precision, the curve transition of high-order ellipse also makes transmission more steady, and these characteristics make the oval movable sleeve tooth transmission of high-order become the good volume transmission component of a kind of transmission performance.
