Abstract: Mounting rings and methods for mounting structures to shafts are provided. The rings and methods may be used to mount other rings or housings to a shaft. The rings are characterized by having flexible inner diameters that can deflect under a radial load. The radial deflection of the inner diameter permits the rings to deflect and engage an outer diameter of a shaft. The engagement of the rings with a shaft provides at least some resistance to movement, for example, rotation and/or axial displacement, of the shaft relative to the ring and structure. In one aspect, the ring has a closed, hollow, construction, for example, a circular, oval, or polygonal closed, hollow construction. The ring may include a plurality of indentations, such as slots, on the inside diameter of the ring that may relieve at least some of the circumferential stress in the ring. Methods for using the rings to mount a structure to a shaft are also disclosed.

Abstract: An outer ring for rocking bearing (11a) includes a raceway surface (12a) on the inner diameter side and has flange parts (13a) and (13b) provided by bending both axial ends to the inner diameter side. The flange parts (13a) and (13b) are provided with bent parts (17a) and (17b) axially bent toward the raceway surface (12a) side so as to enfold a retainer arranged on the inner diameter side. Thus, the retainer can be enfolded by the bent parts (17a) and (17b). Therefore, even when the retainer comes to be moved to the inner diameter side of the outer ring for rocking bearing (11a), the retainer is caught by the bent parts (17a) and (17b), so that the movement of the retainer to the inner diameter side is restricted and rollers and the retainer can be prevented from dropping off.
