A centering device for mounting a flange with a bolt passing through a opening in a mounted state, has a centering disk with a collar surrounding a disk part. The disk part is received in the opening and the collar rests on the flange. An elongated hole in the disk part has, at its respective ends, semicircles of radii R and a straight piece connecting the semicircles of overall length L1. A centering sleeve has a sleeve part surrounded by a sleeve collar wherein the inside diameter D3 of the sleeve part corresponds to the diameter of the bolt and the outside diameter D2 of the sleeve part corresponds to the transverse diameter (2R) of the elongated hole. A locking device fixes the centering sleeve against the centering disk in a predetermined mounting position secure against displacement.

An engineered flexure component for mounting on a substantially flat surface for improving dimensional stability therebetween has a member with an elastic mechanism being connected thereto. The elastic mechanism manages a shear force between the engineered flexure component and the substantially flat surface when the elastic mechanism contacts the substantially flat surface.

A plastic fastener is disclosed. The fastener may be employed in a vehicle generator. The fastener has a plastic body extending through an aperture of a first component and through an aperture of a second component. The body has a first distal head that retainingly abuts the opening of the aperture of the first component. The plastic body also has a second distal head that retainingly abuts the opening of the aperture of the second component. The configuration of the body secures the first component to the second component. The invention further provides a method of fastening components of a vehicular generator. A plastic body with first and second studs is over molded about a first generator component. At least one stud may be extended through an aperture of a second generator component. The studs are then formed into distal heads to secure the first component to the second component.

A swivel hook is described that is comprised of a hook body and a swivel connector. The hook body has a generally uniform thickness and is stamped from a sheet of material. A hook member formed at a first end and a longitudinally oriented stem, having a generally rectangular cross-section, formed at a second opposite end of the hook body. The swivel connector is pivotally securable over the stem and formed from a forged metal. The swivel connector has a generally circular bore of a size exceeding the rectangular cross-section of the stem such that the stem may be received through the bore to secure the swivel connector to the hook body while permitting rotational movement of the swivel connector about the stem. Also described is a method of constructing a swivel hook.
摘要:
A blind fastener device for fastening at least two workpieces, including a sleeve, an expander having a tensioning section, a locking section, and an expansion section, and a nut. A portion of the expander passes through the sleeve to cooperate with the nut so that relative rotation of the expander and nut draws the expander's distal end toward the sleeve's proximal end thereby drawing a portion of the expansion section of the expander into a structural region located on the sleeve and expanding at least a portion of the sleeve's structural region, and drawing a portion of the locking section past the sleeve's distal end toward the sleeve's proximal end and deforming at least a portion of the sleeve's distal end to a locked state. The sleeve may be configured as a multi-section sleeve having a sleeve retainer to locate the sections in a predetermined relationship.

Included is an anti-friction washer system comprising two steel washers coated with a zinc coating that is at least 0.0002 inch thick, the two washers adhered to one another by an adhesive having a melting temperature of 300° F. or less. Also included is a mine roof bolt system comprising: a bolt having a bolt head; a bearing plate; and the above-described anti-friction washer system located between the bearing plate and the bolt head. Also included is a method of manufacturing an anti-friction washer system including providing two zinc-coated washers, depositing a melted thermoplastic adhesive in a plurality of locations circumferentially around one surface of one of the washers, placing the other washer on top of the adhesive, applying pressure to the washers, and cooling the bonded washers.

The invention relates to a washer arrangement for an axial bearing arrangement, particularly in a motor vehicle gearbox, having a first sector element and at least a second sector element, which complement one another to form an annular retaining washer. The retaining washer comprises an inner circumference and an outer circumference. The washer arrangement has a locking ring, which is arranged around the outer circumference of the retaining washer. The locking ring is wound from a wire.

The invention relates to a device for introducing force into a component of fiber composite material by means of a screw connection having a bolt-like connecting element arranged in a passage of the component. The invention is based in particular on the problem of improving the durability of the screw connection on the component of fiber composite material. The object is achieved in that the screw connection has a two-part bush (6) which borders the passage (2) of the component (1) and accommodates the connecting element (9), wherein the first and the second bush part (6.1, 6.2) of the bush (6) are designed to engage in one another in axial extension, and each bush part (6.1, 6.2) has a radially extended union collar (15.1, 15.2) with a collar side (16.1, 16.2) facing the component (1), on which side a sliding surface is formed.

A screw (2) has a head (5) including an underhead bearing surface (12). Lubricant pockets (13) are arranged at least in a part of the underhead bearing surface (12). The lubricant pockets (13) serve to contain lubricant and to release the lubricant when tightening a screw joint (1) to prevent galling effects during multiple tightening processes.
