Abstract:
A tolerance ring includes a ring body having a spring property, an abutment joint portion formed between circumferential end edges of the ring body, and protrusions protruding radially from the ring body, each having a reaction force due to radial rigidity. The tolerance ring includes an abutment joint semi-circumferential region and an opposing semi-circumferential region facing the abutment joint portion. The tolerance ring includes first and second X-direction semi-circumferential regions separated by a straight line connecting the abutment joint and opposing portions. The Y-direction passes through the axis center of the ring body and the abutment joint, and the X-direction is orthogonal to the Y-direction. The sum of the X-direction components of the reaction force vector in the first X-direction semi-circumferential region is the same or smaller than the sum of the Y-direction components of the reaction force vector in the abutment joint semi-circumferential region.
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 connecting assembly for connecting a first member and a second member, and the connecting assembly includes a resilient receiver and a securing plug. The second member defines a through hole. The resilient receiver is fixed to the first member and also defines a receiving space. A top of the resilient receiver passes through the through hole. The securing plug is configured to be inserted into the receiving space, which expands a part of the resilient receiver so as to fix the top of the resilient receiver on the second member thereby connecting the first member with the second member. Present disclosure also provides an electronic apparatus having the connecting assembly.
Abstract:
A method of assembling a tolerance ring 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 whereby the projections are received in a recessed portion 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.
Abstract:
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).
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.
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.

Abstract:
A post mounting arrangement for ground installation of a post comprising a tubular body portion (6) which is adapted to be installed into the ground and has an open end adapted to receive a post (2) to be supported. The open end of the tubular body portion comprises an enlarged flange portion defining a head portion (14) of the tubular main body portion (6). The head flange portion (14) includes a resilient retaining collar (12, 12′) adapted to receive and engage the post, and a strengthening band (8). The head portion (14) comprises a first recess (22) defined therein within which the said collar (12, 12′) is engaged and mounted, and a second recess (20) defined in the head portion adapted to receive the said strengthening band (8). The collar may comprise a shock absorbing element (12′) having a groove (42) capable of receiving an expansion ring (44) to lock the element into place and seal it both to the post (2) and the head portion (14). Alternatively, the head portion (14) further comprises a separate cap (10) which is adapted to be fitted to and engages with said head portion (14) to enclose said recesses (20, 22) and secure said collar (12) and strengthening ring (8) within said recesses.
Abstract:
This invention relates to a process and a device for the damping of motion between two cylindrical parts sliding with one another in translation and friction.According to this invention, the damping is performed by the application of a force exerted radially perpendicularly to the translation motion of the two parts by at least one elastic segment (13) circling one of the parts (11) and inside the other (12), integral in translation with one of the parts (11) and appplying said frictional force on the other part (12).This invention is applicable to the absorption of shocks as well as to that of vibrations.
