An inner ring assembly for a bearing includes a bearing annular body disposable about the shaft and having a bearing inner race and a plurality of slotted openings defining a plurality of arcuate mounting tabs, the slotted openings each having a curved inner end and each tab including a substantial recess to reduce stress concentration. An annular locking collar is disposed about and clamps the mounting tabs against the outer surface of the shaft to retain the inner ring. The collar is retained on the ring body by a retainer projection(s) extending outwardly from the mounting tabs and engaging with the collar or a retainer member projecting inwardly from the collar and engaging with one of the mounting tabs. The collar has a gap and a flat outer surface section spaced from the gap to increase the dynamic balance and the flexibility of the collar.

A decelerating clutch of a washing machine includes a bearing seat, an input shaft, an output shaft, and an output shaft sleeve. The input shaft and the output shaft are coaxial, the output shaft sleeve is sleeved on the input shaft and the output shaft, the output shaft sleeve is installed on the bearing seat via a bearing, the output shaft sleeve is connected with the input shaft via a planetary gear train, two ends and a middle part of the output shaft sleeve are respectively provided with at least one bearing, an inner ring of the bearing is coordinated with the output shaft sleeve, and an outer ring is coordinated with the bearing seat. The decelerating clutch of a washing machine improves a capability of an output shaft sleeve in resisting against a radial load, and further prolongs the service life of a decelerating clutch of a washing machine.

A wave spring having an axially resilient spring section including at least one one-layer wave-shaped spring configured to provide a spring force in an axial direction of the wave spring, and a radially resilient spring section configured to provide a spring force in a radial direction. The wave spring may be made from a continuous flat wire that forms both the axially resilient spring section and the radially resilient spring section, the flat wire being rotated 90° at a transition from the axial spring section to the radial spring section.
