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 device for the forced locking of two elements oriented orthogonally to one another, especially suitable for steadily connecting and constraining two tubular elements (10), (12) with quadrangular or polygonal section which are partly delimited by a U-shaped band (22) and which have, on at least one face, a plurality of pairs of shaped recesses (14), whereas the band (22) is correspondingly provided with pairs of complementary projections (16) developed projecting on the inner front of the opposite vertical and parallel branches (18) and (20) thereof.

Abstract: An alignment pin or fastener includes a radially eccentric part such that when the fastener is tightened, the eccentric part shifts radially to simultaneously align the holes of two plates in a radial direction and clamp the two plates together in an axial direction. The bi-directional fastener includes two heads at opposite ends of a shaft, wherein the two plates become sandwiched and clamped between the two heads. The shaft and the two heads remain fixed relative to each other, so turning one head turns the other. This allows the fastener to be tightened even when only one of the heads is accessible.

Abstract: A lightweight spacer for mounting a vacuum brake booster on a panel provides integral flexible sealing lips to seal the interfaces between the panel, spacer, and booster. Integral retaining tabs are provided for holding the spacer in place on the booster during shipping and installation of the booster. Tubular inserts within the spacer are retained and cushioned against rattling by a thin web of material extending over the end of the insert.

Abstract: Compression exerted by a clamp collar integral to a molded plastic flexible shaft coupling accommodating angular shaft misalignment upon the circumferential outward surface of a radially compressible molded sleeve insert located in a shaft bore of the flexible coupling facilitates engagement of a reduced diameter shaft located within the sleeve insert. Use of a sleeve insert having a different internal diameter similarly accommodates flexible coupling to another diameter shaft. Utilization of sleeve inserts selected from a plurality of different reduced internal diameters and exterior diameters sized to fit either shaft bore enables flexible coupling of both multiple matched shaft diameters and an exponential number of differing opposed shaft diameter combinations within a range limited by the flexible coupling shaft bores. Radial compressibility of the sleeve insert is facilitated by the utilization of resilient material, interruption of the circumferential extension by a longitudinal slot, or both.

Abstract: This application describes the design of the split-tube flexure, a unique precision revolute joint that exhibits a considerably larger range of motion and significantly better multi-axis revolute joint characteristics than a conventional flexure. The development of this joint enables the implementation of spatially-loaded revolute joint-based precision machines with well-behaved kinematic and dynamic characteristics and without the backlash and stick-slip behavior that would otherwise prevent precision machine control.

Abstract: Device for attaching a rod to a wall comprising a clip having a channel section and two parallel lugs. A first sleeve and a second sleeve each have a longitudinal slot. Each of the first and second sleeves have a cylindrical part which is adapted to be disposed between the rod and the channel section of the clip. The clip is adapted to be attached to the wall via the two parallel lugs.

Abstract: A rubber bearing, especially for the bearing support of a stabilizer bar in a motor vehicle, comprises two rubber half-shells. A thin rubber connecting piece connects the longitudinal side of one of the half-shells with the longitudinal side of the other one of the half-shells. The rubber connecting piece is arranged at the radial outer region of the half-shells to enable 180° of rotation of one of the half-shells with respect to the other one of the half-shells about the area of connection.

Abstract: A casing for use in the manufacture of a resilient joint, the casing having an outer surface and an inner surface, the inner surface defining an internal cavity, wherein the casing has at least one frangible wall section which is adapted to fracture upon the application of a compressive force to the outer surface of the casing such that after such fracture the volume of the internal cavity of the casing is reduced.

Abstract: An elastomeric bushing for mounting a first member to a second member which permits limited articulation of one of the members relative to the other. The bushing comprises an inner element, an outer element, and a highly compressed elastomeric insert retained between the outer and inner elements, wherein the outer element further comprises an adjustable portion to permit limited reduction of the circumference of the outer element from a maximum circumference. The outer element is constructed to restrain the expansion forces of the highly compressed elastomeric insert to maintain substantially constant, the circumference of the outer element at a predetermined circumference, while being capable of withstanding the shear forces during installation without buckling or tearing.

Abstract: A mount assembly is described for resiliently mounting a stabilizer bar on an automobile frame. The mount assembly comprises a bracket assembly and a bushing assembly. The bushing assembly includes an outer sleeve adjacent to the bracket and an inner sleeve for contacting the stabilizer bar. The nesting sleeves are designed so as to provide restraint of axial movement while allowing ease of rotational movement. The restraint can be provided by a positive stop such as a projecting flange member, or by cooperating conical or tapered surfaces which defines an increased frictional engagement and compression of the stabilizer bar as the inner sleeve and the outer sleeve move increasingly out of relative axial alignment.

Abstract: A flexible mount for resiliently securing a first member to a second member so that the first member can be deflected relative to the second member in response to an applied force and so that the first member returns to an equilibrium position when the applied force is removed includes an elongate stud having a center axis and a nut threadably engaged on one end of the stud for securing same to the second member and a body of elastomeric material encapsulating and joined to the other end of the elongate stud. The body of elastomeric material includes a body center axis disposed at a small angle with respect to the stud center axis and a tab for securing the first member to the body.

Abstract: A chair assembly mounting apparatus is disclosed which may be employed to mount a chair, gondola, platform, etc. to a hanger arm for use in a chairlift or the like. The apparatus provides a movable connection between the chair frame and hanger arm which reduces vibration and fatigue and yet damps or resists excessive motion. The mounting apparatus includes a rubber-like member which encircles a frame portion, preferably having a flange thereon, and in turn is encircled by a support housing rigidly mounted to the hanger arm. Movement of the frame relative to the hanger arm causes the flange to resiliently displace the rubber-like member.

Abstract: Slip coupling incorporating bearing-quality friction surfaces and a flexible structure that isolates torsional vibration.

Abstract: A flexible joint for use in suspension systems and the like has a rigid cylindrical member, a resilient bushing encompassing the inner member, a split casing having opposed semi-cylindrical surfaces holding the bushing under compression toward the inner member and secured together in bushing-compressing relation, and rigid extrusion barriers preventing compression induced extrusion of the bushing into partings between the casing parts. Configuration of the extrusion barriers complements the compression loading of the resilient bushing by the surfaces of the casing parts.
