A method of assembling a tolerance ring (18) between opposing surfaces of an inner and outer component arranged to mate with one another to provide an interference fit therebetween includes mounting the tolerance ring on one of the inner and outer components (12,14) whereby the projections (20) are received in a recessed portion (22) on that component, partially mating the inner and outer components, and completing mating by causing relative movement between the tolerance ring and the recessed portion to move the projections from the recessed portion and to be compressed between the mated inner and outer components. The tolerance ring includes an annular band of resilient material for engaging an opposing surface of one of the inner and outer components. The annular band has a plurality of deformable projections extending radially therefrom to engage the opposing surface of the other one of the inner and outer components.

A tolerance ring (10) for providing an interference fit between inner and outer components (36, 50). The tolerance ring (10) comprises a deformable band having a plurality of radially extending projections around its circumference. The projections include a set of axially spaced protuberances (12, 13) separated by an unformed region (11) circumferentially adjacent to an axially elongate protuberance (15), the axial extent of which spans the axial extent of the set of axially spaced protuberances. This arrangement of protuberances facilitates the transfer of retention force to a component that is composed of a plurality of independent parts, e.g. two or more bearings (54, 56) separated by a spacer (58).
A tolerance ring (10) for providing an interference fit between inner and outer components (36, 50) is disclosed. The tolerance ring (10) comprises a deformable band wound to form a first layer (111) having a plurality of radially extending projections (12, 13, 15) around its circumference and an unformed second layer (110) which overlaps with the first layer. The second layer acts as a force diffuser to spread the forces transferred through the projections on to the inner or outer component.
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.
F16B 2/24 - Clips, i.e. with gripping action effected solely by the inherent resistance to deformation of the material of the fastening of resilient material, e.g. rubbery material of metal
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.
A shaft is held in place within a bore of a housing with a band of resilient material that is located between the shaft and the housing and has a series of projections extending radially inwards. The shaft surface has a first part that lies closer to the longitudinal axis of the bore than a second part, when the shaft and housing are assembled. The shaft is initially inserted into the resilient band, which is held within the bore, such that the first part of the shaft surface is oriented towards one of the projections of the resilient band. In this orientation of the shaft, the projection is not compressed. By orienting the second part of the shaft surface, the projection is brought under compression and the shaft is held firmly within the bore.
A thin component such as the actuator arm (10) of a hard disk drive, is mounted on a pivot or pin (31), such as the pivot assembly of the hard disk drive, using a ring (32), e.g. a tolerance ring, having one or more projections (35), wherein the engagement of the component (30) and the ring (32) is such as to apply a force to the component (30) in a direction which is inclined to both the radial and axial directions of the pivot or pin (31). The pivot or pin (31) has a flange onto which the component (30) is pressed by the axial component of the force generated by the ring on the component. The edge of the ring (32) remote from the component (30) is engaged with a stop element, e.g. another flange (34) of the pivot or pin (31).
An apparatus is shown which comprises first and second mating components with a force limiter located between them. The force limiter includes a band of resilient material, with protrusions therealong, and a slip element. The band and the slip element are secured to the first mating component with the band arranged to apply a radial force against the slip element so as to press it against the second mating component.
The frictional force between slip element and the second mating component is insufficient to separate the slip element and the band from the first mating component, so any slipping that occurs between the mating components happens at the boundary of the slip element and the second mating component.
A desired slip force can be obtained by choosing a slip element with an appropriate coefficient of friction, rather than by varying the dimensions of the components.

APPARATUS FOR TOLERANCE RING CONTROL OF SLIP INTERFACE SLIDING FORCES
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.
