Abstract:
A welding auxiliary joining part in the form of a bolt having a head, a shank and a tip is disclosed. The welding auxiliary joining part is driven with the aid of a mechanical thermal setting method into a component made of non-weldable or poorly weldable material. During the driving-in operation, a welding head arises on account of mechanical deformation, such that subsequently the component can be connected via the welding auxiliary joining part to a further component made of weldable material by means of welding.

The rib attachment member may be attached to a side-of-body rib.
Abstract:
An adhesively bonded joint in a boom arm (20) of an agricultural sprayer (10) has a tee-shaped brace member (70) with a top flange (72) and a stem (74) extending from the top flange (72). A brace-receiving portion (60) of the joint has a slot (62) formed therein that receives the stem of the tee-shaped brace member. The sides of the stem (74) and underside of the top flange (72) are adhesively bonded to facing surfaces of the brace-receiving portion (60).
Abstract:
The present invention relates to a fastening arrangement (1) for fastening a component, in particular a cabin component, to a structural component (12) of an aircraft or spacecraft, comprising a structural component (12) which comprises a connection surface (13- 7); a fastening fitting (2) which has a geometry matched to the geometrical shape of the structural component (12), has a connection portion (3-7) associated with the connection surface (13-17) of the structural component (12) and is produced from a thermoplastic injection-moulding material; and an elastomeric adhesive joint (25) for stable fastening of the connection portion (3-7) of the fastening fitting (2) to the associated connection surface (13-17) of the structural component (12). A corresponding fastening fitting (2) and an aircraft or spacecraft comprising a fastening arrangement (1) of this type and/or a fastening fitting (2) of this type are also claimed.
Abstract:
A method of forming an aerodynamic arrangement (10) comprises providing a plurality of segments (16), providing elongate connecting means (20). The segments are connected to one another with the elongate connecting means. The method further includes introducing a curable securing composition into the connecting means, and allowing the securing composition to cure.
Abstract:
Eine Vorrichtung (1) zur reibschlüssigen Kupplung zweier koaxialer Bauteile (4, 5, 41, 42), insbesondere zweier Wellen (41, 42) oder einer Welle (4) und einer Nabe (5), weist ein erstes, inneres Kupplungsteil (2) mit kegelförmiger äusserer Mantelfläche (22) und ein zweites, äusseres Kupplungsteil (3) mit kegelförmiger innerer, Mantelfläche (32, 52) auf. Die beiden Kupplungsteile (2, 3) sind dazu geeignet, in Richtung einer Längsachse (11) reversibel derart aufeinander geschoben und dabei in radialer Richtung elastisch verformt zu werden, dass die kegelförmigen Mantelflächen (22, 32, 52) aufeinander aufliegen, und die zwei koaxialen Bauteile (4, 5, 41, 42) aufgrund der durch die elastische Verformung der Kupplungsteile (2, 3) verursachten radialen Kräfte über die Kupplungsteile (2, 3) miteinander reibschlüssig verbunden sind. Das äussere Kupplungsteil (3) weist an seinen beiden Längsenden auf der kegelförmigen Mantelfläche (32) je mindestens eine umlaufende Dichtung (35', 35") auf. Die dazwischen liegende Mantelfläche (32) ist mit einer den Haftreibungskoeffizienten erhöhenden Beschichtung (321) versehen.
Abstract:
A joining element to be anchored in an object (10) with the aid of a thermoplastic material and mechanical vibration comprises a sealing portion (3.1) and a wall anchoring portion (3.2). The sealing portion (3.1) is substantially cylindrical and has a smooth circumferential surface. The wall anchoring portion (3.2) has a circumferential surface which comprises the thermoplastic material and energy directors. A cross section of the sealing portion (3.1) envelops the cross section (including energy directors) of the wall anchoring portion and is arranged adjoining to the latter on its proximal side. The joining element is anchored in an opening (5) provided in the object (10) wherein a cross section of the opening corresponds to the cross section of the sealing portion (3.1) of the joining element such that the latter can be forced into a mouth (5.1) of the opening (5) resulting in a press fit. For anchoring the joining element in the opening (5), mechanical vibrations e.g. ultrasonic vibrations are coupled into the joining element and the latter is forced into the opening (5) until at least a distal part of the sealing portion (3.1) is positioned within the opening. Thereby, the thermoplastic material of the circumferential surface of the wall anchoring portion (3.2) is liquefied and pressed into the opening wall, wherein the sealing portion (3.1) prevents the liquefied material to penetrate through the mouth and therefore the mouth (5.1) remains clear cut, i.e. does not get blurred by the liquefied material.
Abstract:
A determinant assembly feature for a joint assembly (10) is provided. The joint assembly (10) includes a structure (12), a web (16) connected to the structure (12). The structure (12) includes a base, a pair of axially elongated legs (20, 22) extending from the base to define a channel (21) therebetween, and one or more location control receiving element (24-29) in either axially elongated leg (30-35). The web (16) includes one or more location control element (30-35), wherein the location control element (24-29) of the web (16) is correspondingly matched to the location control receiving element (24-29) of the structure (12), whereby an assembly location control is achieved. A method of assembling a joint assembly (10) of the present invention is also provided.
