Research on pure rolling cycloid-like reducers used in industrial robot

A new transmission profile named cycloid-like profile is presented in this paper. The reducer with cycloidlike profiles has a character of pin wheels pure rolling, which can gain a high transmission efficiency. The design process with two conditions of pin wheel pure rolling are described in details and the comparison between cycloid-like and cycloid profiles are taken. At last, prototype experiment is employed to testify the validity and feasibility of the approach to the pure rolling cycloid-like gear reducer.
