Abstract
A harmonic drive transmission arrangement has an input member and an output member. The transmission comprises a generally cylindrically shaped housing including having a circular spline gear arranged therein, and a cup-shaped flexspline with an array of radially outwardly directed gear teeth on a first end thereof, engaged with the circular spline teeth. A wave generator is rotatably supported on the input member radially inwardly of the gear teeth on the flexspline, and an annular diaphragm is arranged at a second end of the cup-shaped flexspline. A flange is arranged integral to the diaphragm to permit the cup-shaped flexspline to be securely attached to the output member, for the transmission of input through she harmonic drive transmission arrangement, and out the output member through the flange. A "U" shaped channel is annularly arranged between the diaphragm and the flange to distinguish the flange from the diaphragm.
