Abstract:
An assembly including an outer member; an inner member; and a tolerance ring disposed between the inner member and the outer member, wherein the tolerance ring is a split ring comprising opposing edges, where the edges engaged with at one of the inner member or the outer member so as to prevent or restrict movement between the tolerance ring and at least one of the inner member or the outer member, or where the tolerance ring is deformed as installed between the inner member and the outer member and forms at least one buckled region in the tolerance ring due to an interference fit between the inner member and the outer member, where in an uninstalled state, the buckled region is absent.
Abstract:
Systems and methods include providing a tolerance ring with a friction enhancement feature on at least one surface of the tolerance ring to increase at least one friction-related property of the tolerance ring. The friction enhancement feature provides the tolerance ring with an increased retention force while providing an optimum radial force that allows a component secured by the tolerance ring to move freely while reducing or altogether preventing axial movement of the component.
Abstract:
A friction brake including a shaft having an input end and an output end, at least one lock collar, at least one tolerance ring disposed between the lock collar and the shaft providing an interference fit therebetween, and a locking component adapted to engage the lock collar to prevent rotation of the lock collar.
Abstract:
A bearing for disposition between a housing and a rotating member, the bearing including: at least one leaf spring element that provides a biasing force in a Y direction; where the bearing has a first stiffness, S1, in the Y direction and a second stiffness, S2, in an X direction perpendicular to the Y direction, where S2≥S1, and where the bearing includes a metal substrate and a low friction layer overlying at least one surface of the substrate and adapted to contact the rotating member.
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.
Abstract:
A tolerance ring including a sidewall and at least one projection from the sidewall that projects radially and axially to prevent axial displacement of the tolerance ring with respect to a component interior or exterior to the tolerance ring.
Abstract:
A linear motion assembly including a component having a longitudinal axis and adapted to translate along the longitudinal axis, and a bearing comprising a spiral body including a substrate and a low friction material, wherein the bearing extends around the component and provides a low friction interface for translation of the component, and wherein the bearing is adapted to prevent longitudinal translation of the component in a locked condition and permit longitudinal translation of the component in an unlocked condition. In an embodiment, the bearing is adapted to transition between the locked and unlocked conditions upon circumferential translation of an axial end of the spiral body, longitudinal translation of an axial end of the spiral body, or a combination thereof.
Abstract:
A torque limiting tolerance ring that is configured to be installed between an inner component and an outer component is disclosed. The torque limiting tolerance ring can include a generally cylindrical body that can have a sidewall. The sidewall can include an unformed section and a plurality of projections can extend from the unformed section of the sidewall. The projections can be configured to engage the inner component or the outer component. During use, the torque limiting tolerance ring can move from an engaged configuration, in which the inner component is statically coupled to the outer component, to a disengaged configuration, in which the inner component is disengaged from the outer component.

Abstract:
A bearing including a generally cylindrical sidewall including an electrically conductive substrate, and an electrically non-conductive or low-conductive sliding layer coupled to the substrate, where the generally cylindrical sidewall includes a plurality of protrusions protruding radially inward or radially outward from a bore defining a central axis, where at least one protrusion is adapted to contact an opposing component such that at a point of contact the bearing has a void area free of sliding layer so as to provide electrical conductivity between the bearing and the opposing component, and wherein at least one protrusion has a spring rate of not greater than 30 kN/mm, such as not greater than 25 kN/mm, such as not greater than 15 kN/mm, or such as not greater than 10 kN/mm.
