Abstract
A method of developing a flex spline and circular gear tooth profile for a harmonic actuator is provided. The method includes defining circular gear and flex spline centroids based on gear ratio calculations, finding mid-points between the centroids of the circular gear and the centroids of the flex spline and transforming the mid-points into a mapping of the tooth profile for respective teeth of the circular gear and the flex spline.
