  • Patent number: 7922418
    Abstract: A mounting assembly comprising mating inner and outer components (36, 38) mounted together using a tolerance (20) is disclosed. The tolerance ring (20) has radially extending projections (28) that are configured to cause the tolerance ring (20) to operate into the plastic phase of its compression force/retention force characteristic. This can be achieved by using softer projections than those found in conventional tolerance rings. The force required to mount the tolerance ring and a range of retention forces exhibited by it for a given variance in sizes of mating components is thereby stabilized.

  • Patent number: 7922419
    Abstract: A combination mounting ring of resilient material, for connecting a shaft within a bore of a housing, has a hollow cylindrical part having radially extending projections. This part is for locating between the outer surface of the shaft and the inner surface of the bore, the radially extending projections being under compression and thus securing the shaft within the bore. The combination mounting ring further has an axial spring element extending radially inward from the cylindrical part and having two portions at different axial positions. The axial spring element is for locating between the shaft and a body axially displaced from the shaft, and serves to minimize axial movement of the shaft within the bore of the housing. The axial spring element may either be an annular part or a tab extending from an axial edge of the cylindrical part.

  • Publication number: 20110076096
    Abstract: A tolerance ring comprising a metallic band for spring features and a complementary low friction material for frictional considerations is disclosed. The tolerance ring is designed to operate within a precisely controlled torque or axial force band to provide a defined amount of resistance and sliding force control between components that move relative to each other. Isolated portions of the tolerance ring form regions of contact with adjacent ones of the components. Other surfaces of the tolerance ring comprise portions with spring features that have geometry suitable for their spring rate, rather than conforming to mating surfaces of the adjacent components.

  • Publication number: 20100321832
    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.

  • Patent number: 7850389
    Abstract: A tolerance ring configured to prevent interlocking during shipping and handling. The tolerance ring has a cylinder with a first radius about an axis of rotation and a gap in the cylinder surface having a first edge and second edge extending along the axis. The gap in the cylindrical base has a first tab on the first edge and a second tab on the second edge. The first tab is adapted for coupling to the second tab and thereby prevents the interlocking of one tolerance ring with another. The gap can be configured to be non-linear.

  • Patent number: 7731446
    Abstract: A joint includes at least one joint bushing and a joint bolt or pipe that is rotatably mounted with radial play in the joint bushing, forming an annular bearing gap. The joint has a play compensation element having several spring-loaded sections that engage in the annular bearing gap. The radii of the spring-loaded sections are shorter than the radius of the annular bearing gap. The spring-loaded sections project beyond a base body of the play compensation element at an acute angle to the joint axis. If the play compensation element is designed both to compensate the play and to axially secure the joint, it includes at least one clamping section, which is/are supported on the joint bolt and project(s) beyond the opposite side of the base body of the play compensation element to the spring-loaded sections. The play compensation element can be used in particular for joints of adjusting devices in motor vehicles.

  • Patent number: 7614818
    Abstract: An assembly having a shaft (11) with external splining (23) of a limited length at a shaft end (27), and a hub (41) with a corresponding internal splining (43) that extends essentially the length of the hub. A first axial securing mechanism functions between the shaft and hub, prevents the hub from sliding further onto the shaft, and includes a stop surface (44, 46) on the hub and a counterpart surface (28, 59) on the shaft. A second axial securing mechanism functions between the shaft and hub, prevents the hub from being pulled off from the shaft, and includes a securing ring (51) that is situated at the end of the shaft and the end of the hub oriented toward the shaft end and that engages in radial recesses (48, 54) in the shaft and hub. The recesses form contact surfaces for the securing ring on the shaft and hub.

  • Patent number: 7611303
    Abstract: A tolerance ring for applications requiring high axial static friction has contacting portions having a novel profile. The use of multiple contacting portions having a smaller size that are wedge-shaped increases rigidity and provides a directional grip that increases axial static function. Using multiple wedge-shaped contacting portions with appropriate opposite slants provides a balanced and symmetrical grip. Using inter-level wedge-shaped contacting portions with opposite slants provides a more aggressive grip while providing a tolerance ring that is more dynamically stable and has a high resonant frequency.

  • Patent number: 7437857
    Abstract: A compression anchor for holding a support member, such as a cylindrical handrail, is disclosed. The anchor includes a body having a cavity and a wedge portion that connects to the body using thick threads, such as 2-4 ACME 2-G threads. The wedge is substantially cylindrical and encircles a support member received in the cavity. A compression ring is in contact with the body and the wedge portion. As the wedge portion turns relative to the body using the threads, the compression ring expands and contracts to loosen or tighten the connection between the received support member and the anchor. The wedge portion and the body are corrosion resistant.
