Abstract
A coupling includes a diaphragm assembly, a sleeve, a stud, and a ball bearing system. The diaphragm assembly includes a first end, a second end, and an opening extending axially through the diaphragm assembly with the diaphragm assembly also including a first annular diaphragm pair. The sleeve extends into the opening and has a bore. The stud extends at least partially within the bore of the sleeve and within the opening. The ball bearing system is concentric with and radially between the sleeve and the stud with the ball bearing having an outer race adjacent to the sleeve, an inner race adjacent to the stud, and at least two rows of ball therebetween with the outer race having an arced shape when viewed in a circumferential direction to allow for axial movement of the at least two rows of ball bearings relative to the outer race.
