【 摘 要 】

There are some shortcomings for the ordinary gear transmission such as friction, noise, low efficiency and so on; with the contactless magnetic coupling transmission, these can be weakeness greatly. This paper introduces the development course of the traditional various transmission method to further illustrate the possibility and characteristics of single-side coupled of rare earth permanent magnets used as gear teeth for magnetic suction gears. it also introduces the basic design principles of the internal and external meshing magnetic gears and the calculation of the transmission torque in gear is coupled. Through the quantitative analysis of the experimental data, the relationship between the transmission torque of the magnetic gear and the relative rotation angle, working airgap, flux leakage is obtained. Finally, the relevant conclusions and formula for calculating torque of magnetic suction gear reducer design criteria are obtained.
