Open the CIPO recordAbstract From the Canadian patent
A strain wave gearing comprising a circular spline flexspline inside the circular spline, a wave generator for deforming the flexspline into, for example an ellipsoid and a, motor for rotating the wave generator to produce a relative rotation between the flexspline and the circular spline. The strain wave gearing is sometimes termed a harmonic drive transmission, and there is a type of gearing called flatshaped strain wave gearing which is composed of two circular splines juxtaposed with each other, a flexspline in the circular splines having the same number of teeth as the first circular spline, a wave generator for deforming the flexspline into an ellipsoid and a motor for rotating the …
