Title:
偏位かみ合いインボリュート歯形を有する撓みかみ合い式歯車装置
Document Type and Number:
Japanese Patent JP4392771
Kind Code:
B2
Abstract:
A flexible meshing type gear device has a rigid internal gear, a flexible external gear disposed inside the internal gear and a wave generator for flexing the external gear into an elliptical shape. One circle of curvature at the point of contact of the involute curve making contact at the meshing center position is made coincident with a tooth profile circle of curvature satisfying the Euler-Savary equation that applies between the tooth profile curvatures at the tooth profile contact points of speed change gears, and the other tooth profile circle of curvature of the equation is defined in the vicinity of the circle of curvature of the other involute curve.
