유성기어트레인 설계시스템의 개발

Planetary gear train is more compact in form and endures larger transmission power than other gear systems. The usability is increased in that the mesh is full and constant, and thus it is necessary to study for the design of planetary gear train. In this paper, we have developed the planetary gear train design system which determines gear dimensions such as module, teeth number, helix angle, facewidth, profile modification coefficients. The dimensions is calculated by using optimization technique to minimize the volume of the gear train and satisfy design constraints which include gear strength, interference, etc.
