introduction：The tooth profile of the outer gear is a distorted cycloid、The inner gear tooth is a planetary gear drive composed of an inner meshing gear and an output mechanism of a round pin。Except for the tooth profile of the gear,The other structure is the same as the planetary gear transmission with small tooth difference. The transmission ratio of the cycloidal pin wheel planetary reducer is about6～87，Efficiency is generally0.9～0.94。figure[Formation of tooth curve]Is the forming principle of the tooth curve。Occurs when the circle rolls over the base circle，if[0004-01]Greater than1，[m1]The dots are the long epicycloids；if[0004-02]Less than1，[m2]The dots are the short epicycloid;Use one of these cycloids
