ABSTRACT:
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 joints. The coupling may be made utilizing either metallic or nonmetallic parts without loss of integrity. A method of assembling and disassembling the joint using thermal processes is also disclosed. The shaft ends are machined with the polygonal shapes and form shoulders with the central area of the shaft to serve as stops when joining the diaphragms to the shaft.
