摘要： A bearing retainer that holds a bearing in a bearing seat of an electromagnetic device has a unique construction that reduces its cost of manufacture. The bearing retainer has a peripheral edge with a plurality of radially extending tabs centered in gaps in the peripheral edge. The tabs connect with tabs of adjacent bearing retainers, allowing a plurality of interconnected bearing retainers to be nested on a steel sheet from which the retainers are stamped, thereby optimizing material use and reducing costs. The bearing retainers are composed of martensite which eliminates a heat tempering process required of prior art retainers and further reduces costs.

摘要： A pulley is provided with first and second disks each having an outer surface and an inner surface, and a center hole with a center axis. Each disk has a hub formed at its center hole that extends outwardly from the disk outer surface. The inner side of each disk has a drive surface and a connection surface extending around its respective center hole. The connection surface is perpendicular to the center axis and the drive surface is angled relative to the connection surface to form the outer surface of each disk with a generally concave shape. The connection surfaces of the first and second disks are abutted and secured together using a fastening mechanism. The disks are arranged where the drive surfaces form an annular groove around the hubs and the hubs of each disk are aligned concentrically with the groove.

摘要： A pulley is constructed from a pair of identical pulley halves, each having a central opening with a series of notches extending therefrom. A hub member extends through the pulley half openings, and outwardly deformed rings are formed in a side wall of the hub member to sandwich portions of the pulley halves thererbetween adjacent the openings in the pulley halves. The rings are formed in a bulging process. The rings deflect inwardly into the notches, to prevent the pulley halves from rotating relative to each other when the pulley halves are assembled together.
