Abstract
We explain the applications of the cyclo gear reducer. For the epitrochoid gear that we design, one epitrochoid curve gear forming from several parameters is installed on the side, and the other gear consisting of different epitrochoid curve shape is installed on the other side. The slide link with the small roller as one part of the internal sun gear moves along the direction of the rotation axis of the epitrochoid gear in the cyclo gear reducer in order to achieve the variable transmission.
