A method of making an elliptoidal internal journal type wave generator for use with a flexspline, the latter having internal spline teeth, an outer diameter (O.D.) designated two times the radius (R), and a radial deflection (d) for spline meshing at minor axis localities with diametrically opposed spline teeth of at least one rigid circular spline, the method comprising: a. providing a circular wave generator ring with a radially inner wall diameter (I.D.) equal to twice R plus three times d, and a ring thickness 1.3 to 1.4 times the inner wall I.D.; b. opening the ring by forming only one gap at least eight times d in circumferential dimension; c. radially reducing the ring portion diametrically opposite to the gap to enhance radial flexibility of the ring while still enabling it to maintain its I.D. dimension; d. compressing the ring along an axis perpendicular to a median through the gap and the reduced portion to circumferentially decrease the gap until permanent deformation occurs establishing a minor axis dimension in the ring corresponding to loose meshing of the spline teeth; and e. further closing the gap to selectively decrease the minor axis dimension to enable the ring to preload the spline teeth. |
