【Abstract】 Gear power transmission is the most common way of variable speed transmission,the theory is still not changed many years,shifting the speed and transmitting the energy is accomplished by direct contact teeth,resulting in friction,noise and low efficiency,Whereas non-contact variable speed transmission based on permanent magnetic gear nowadays draw people’s attention for reducing such defects.This article summarized the development of permanent magnetic gear.Firstly,introduced the meaning of studying it,and ordinary ways of variable speed transmission.Then the course of its development.Finally,expounded the operating principle and fundamental structure.更多还原
