A coupling is disclosed having an interference fit between its diaphragms and the spacer tube wherein the diaphragm bore and the spacer tube shaft end have mating polygonal shapes. In a preferred embodiment, the polygonal shapes are rounded, with rounded edges and comers to eliminate stress points. Localized stress areas are virtually eliminated because of the lack of concavities in the shaft end. The contact area between the diaphragm and the spacer tube thus increase the torque capacity of the coupling and eliminate fretting associated with splined joi...
[ What is claimed is:] [1.] A power transmission coupling for transmitting rotary energy from a first device to a second device, the coupling allowing both angular and axial misalignment between the first and second devices, the coupling comprising:a coupling shaft having a first end;a first shaft end extending from the first end and having a substantially triangular shaped cross-section with three convexly rounded corners and three convexly rounded sides; and,a first diaphragm having a bore, the bore having a cross-section which substantially matches th...
