Design and Application of Magnetic Coupling Used for Ultra-high Vacuum Robot

Aiming at the solutions of leaking problems exist in some special industries including the vacuum robot area, we bring out the technology of magnetic transmission module used for ultra-high vacuum robot. Though the magnetic transmission technology had been expanded rapidly for decades with the development of magnetic materials in the 1970s, there are scarcely some cases to use magnetic transmission for robots in China. The principle of the magnetic transmission is presented in the beginning of this paper and then we introduce the designing process of the magnetic coupling. During the process of designing we use the ANSYS software to do analysis of the magnetic circuit to achieve optimization. In the end of the paper we draw a conclusion that the magnetic coupling designed by us is fit for the power transportation for ultra-high vacuum environment and the torque can be transmitted meet the designing goal. There is no doubt that this technology is of great developing foreground in the near future and the application of it will contribute a lot to the world.
