A Study on Shape Design Method by Instant Velocity Centers of Rotating Outer-Ring Type Epicycloid Plate Gear

순간속도중심을 이용한 외륜회전형 에피사이클로이드 판기어의 형상설계법에 관한 연구

This paper proposes a new approach for the shape design of the rotating outer-ring type epicycloid plate gear by using instant velocity center. First, this method defines the instant velocity centers for rotating outer-ring type epicycloid plate gear and calculates the contact angles and the contact points by using the geometric relationships and the kinematic properties of the reducer. Second, it generates the full shape of the cycloidal plate gear. Finally, the paper develops CAD-program for construction of the design automation using the proposed method. This CAD-program is developed to have the functions of the friendly user interface and the simulation of the real operation for the cycloid reducer.
