ABSTRACT:
A flexible coupling formed from sheet material and having preselected stiffness characteristics is incorporated between an engine output member and an input member of a mechanism to reduce the linear vibration levels of the system in use and to accommodate a preselected amount of misalignment therebetween. The flexible coupling has radially outer and inner edge portions, and a formed intermediate portion connecting them which in cross section has a generally truncated V-shape. A preferred embodiment has an annular body with the intermediate portion thereof having conical outer and inner walls, a relatively flat end wall, and blended corners connecting the walls and edge portions. When used between a diesel engine and an electric generator set the formed flexible coupling shifted the major structural resonances away from the normal operating range and greatly reduced the linear vibration levels thereof.
