[0002] In 1968, M, R, and Kuehnle, presidents of Coulter Corporation of the United States, obtained an American invention patent named "Toroidal Trasmission". This invention integrated rolling contact technology and planetary worm transmission technology. , compact structure, etc., but it is very difficult to manufacture. Later, a research team led by Professor H. Peeken and the American Coulter company were jointly researched by the former West German Ashen University for 4 years. The first test prototype was only in the 1980s. Early release
In November 1981, M, R, and Kuehnle of the United States obtained another American invention patent named "Mechanical power transmission method and means". Very few, still in the exploratory stage, the machining of the internal spiral groove of the stator, the key part of the mechanism, is the most difficult, and it is not easy to manufacture the corresponding special plane. In addition, the special plane does not have the flexibility of manufacturing, which greatly hinders the scheme of this kind of transmission mechanism implement
Since 1982, some domestic units have also carried out research on this, but they only focus on the principle of meshing and optimal design, lacking effective engineering design and manufacturing technology

Embodiment Construction
[0015] figure 1 It is a set of two-stage toroidal planetary worm transmission mechanism, which can be used as a yaw reducer for 1.5-2.0 MW wind turbines. The total reduction ratio is 1400, the first-stage reduction ratio is 50, the outer diameter of the stator is 280mm, The secondary reduction ratio is 28, and the outer diameter of the stator is 400mm. The rotary motion of this mechanism is input by the central worm 2 of the first stage, which drives at least two planetary gears 1 cascaded to the planet carrier 7 to rotate, through the spiral grooves of the stators 4 and 5 and the rolling steel balls 3 in the transmission mechanism. The meshing drives the rotation of the planetary carrier 7 so as to realize the deceleration output of the motion of this stage; and the output of the first stage is the input of the second stage. Depend on figure 1 It can be seen that the end of the first-stage planetary carrier 7 extends all the way to the inner cavity of the second-stage plane...

The invention relates to a multi-stage toroidal planet worm transmission mechanism and a method processing a stator thereof. The transmission mechanism is formed by connecting multi-stage (at least two-stage) toroidal planet worm transmission mechanisms in series. The transmission mechanism is characterized in that in each toroidal planet worm transmission mechanism, a stator, a central worm and an arc chock block fixedly connected to a planet carrier completely surround a rolling steel ball to keep the rolling steel ball from falling; in addition, the stator and the bottom center of aspiral groove way of the central worm are also provided with arc grooves of which radii are r. The processing method comprises the following steps: selecting an angle head capable of adjusting angles, mounting the angle head on a main shaft of a five-shaft digital control milling machine, and processing the spiral groove way in an inner cavity of the stator according to a program. The transmission mechanism has the advantages that an extra-large (over 1,000) transmission ratio can be realized by a compact structure, the work is reliable, and the service life is long.
