Twisting tests for cup type strain wave gearing (commonly known as harmonic drive gearing) were done to grasp torsional factors of the gearing. Also the radial flexural deformation of flexible spline (=F. S.) which was one of the structural elements of the gearing was measured with 3-dimensional coordinate measuring machine to consider the effects of flexural deformation on torsion. From the results obtained, the strain wave gearing had hardening spring characteristic, and for torsional factors of the gearing, not only cylindrical torsion of F. S. but also several torsional factors due to flexural deformation of open side of F. S. which meshed with circular spline were grasped experimentally. The sum of torsion caused by each of the grasped factors became about 95% of the whole torsion of the gearing.
