摘要:
A nut plate assembly includes a plate member, a shell member, a nut, and a bias member. The shell member includes a first end coupled to the plate member and a second end opposite the first end. The nut is disposed within the shell member and is moveable between a first position proximate the shell member first end and a second position proximate the shell member second end. In addition, the bias member is disposed within the shell member and is configured to bias the nut toward one of the first position and the second position.

The present invention relates to prevailing torque lock nuts and, more particularly, to a low profile lock nut that maintains the same strength as its higher profile counterparts. The present lock nut is a non-metallic lock having an inner recess so as to receive a plastic insert, such as a nylon insert. In some embodiments, the plastic insert is a temperature resistant plastic insert capable of withstanding high temperatures. Further, in some embodiments, the present lock nut is manufactured to have increased hardness levels and subject to enhanced plating process that ensure superior corrosion resistance.

This invention relates to an earthing bond seal for sealing between a flanged bush of an earthing bond and a substrate with which the flanged bush is to form an electrical connection, the seal comprising: an upper surface for engagement with the flange of the bush; a lower surface for engagement with the substrate; and an opening extending between the upper and lower surfaces, wherein the upper surface is provided with a first recess configured to receive the flange of the bush.

Metallic connectors or fasteners are often required in, or when making connections to, components or structures made of fibre reinforced composite materials. However, the location of these fasteners is often the site of structural failures due to corrosion or stress concentrations or other localised failures. This invention relates to an improved fastener or connector that provides improved integration with composite materials, and which can be used to minimise the possibility of corrosion damage while at the same time providing improved mechanical joints with reduced likelihood of stress concentrations leading to breakdown of the composite material surrounding the connector. The connector has a body section which has a graduated stiffness, the stiffness of the body section being greatest at a connection between the body section and a mechanical fastening section of connector, and the stiffness being least at the extremities of the body section. And the connector is made by electron beam melting allowing for cost effective use of titanium or titanium alloys to make the connectors, and providing for an improved strength to weight ratio and improved corrosion resistance.

Un moyeu (ME) est destiné à équiper un essieu de véhicule et à être solidarisé par vissage à une roue (R) comportant un voile (VR) muni d'au moins deux premières zones (Z1 ) sensiblement planes et comportant chacune un premier trou (T1) propre à être traversé par une tige (TV) d'une vis (VS). Ce moyeu (ME) comprend un disque d'interface (Dl) muni d'au moins deux secondes zones (Z2) planes et comportant chacune sur une face arrière (FR), opposée au voile (VR), un logement (LE) dans lequel est défini un second trou (T2) et est immobilisée une partie périphérique (PP) d'un écrou (EV) présentant une forme concave par rapport à cette face arrière (FR) et propre à définir une réserve élastique pour le serrage d'une vis (VS) participant au vissage de la roue (R).
