Abstract: A tolerance ring can be disposed between an inner component and an outer component, the inner and outer components defining stepped sidewalls. In an embodiment, a preassembly can include an outer component defining a bore having a stepped inner sidewall, an inner component having a stepped outer sidewall, and a tolerance ring adapted to be disposed between the inner component and the bore. In an embodiment, an assembly can include an outer component defining a bore having a stepped inner sidewall, an inner component having a stepped outer sidewall, and a tolerance ring disposed between the inner component and the bore. In an embodiment, a hard disk drive preassembly can include an actuator arm defining a bore having a stepped inner sidewall, a pivot having a stepped outer sidewall, and a tolerance ring adapted to be disposed between the pivot and the bore.

Abstract: A tolerance ring has a band with outwardly extending corrugated protrusions forming waves that engage an outer surface of a shaft. At one end of the tolerance ring is an inwardly flared guide surface extending axially and radially from the band. The guide surface acts as a tapered entrance to a bore of a housing to assist during assembly.

Abstract: A tolerance ring for a hard disc drive assembly is disclosed and can include a plurality of discrete tolerance ring panels. Each tolerance ring panel can include an arcuate sidewall that can include an unformed portion and at least one projection extending from the arcuate sidewall. The projection can be surrounded by the unformed portion of the arcuate sidewall and the tolerance ring can be configured to be deployed in an interference fit between an inner component and an outer component to provide torque coupling between an inner component and an outer component.

Abstract: A tolerance ring is adapted to be deployed between inner and outer components. The tolerance ring includes a generally cylindrical body. The sidewall can include an undeformed portion. The sidewall can further include a plurality of wave structures. The wave structures can protrude radially from the undeformed portion. Some or all wave structures can protrude inwardly or can protrude outwardly. Furthermore, the tolerance ring when placed in an assembly having an inner component and an outer component can have a first torque break-point T1 in a first rotational direction. A torque break point for an assembly comprising an inner component, an outer component, and a tolerance ring is the torque at which slippage occurs.
