摘要:
A large thrust ball bearing, retainer, and raceways, using a surface treatment such as hard anodize, lowers the friction and wear. The retainer, molded in synthetic resin with self-lubricated material reinforced with carbon fiber such as MoS2, and PTPE, eliminates the thermal viscosity. Multi-segment retainers, each with an inner race-guided configuration, an alternative ball pocket cross-section design with a slotted configuration, reduce the thermal effects, improve the producibility of the retainer, and reduce the manufacturing cost. The pocket design with an oval cross-section instead of a circular cross-section also reduces the localized thermal-induced effect which would otherwise result in a pinching condition between the ball and the retainer. The alternative slotted retainer pocket design increases the compliance between ball/pocket interfaces, which helps to reduce the dynamic effects. The ends of the retainer segments are designed to reduce the interactive transferring, circumferential force between two adjacent segments.
