摘要:
A male fastener, female fastener, and a wedge that is adapted to secure the female fastener to the male fastener, and to prevent unwanted loosening of the female fastener from the male fastener. The male fastener includes a shaft that may optionally include a plurality of protruding elements that extend outwardly from an external surface of the shaft. The protruding elements may be radially positioned in rows around a circumference of the shaft, to create a channel between the rows of protruding elements. The channel is adapted to receive a corresponding thread located within an aperture of the female fastener. The wedge is adapted to be inserted into a space located between a set of protruding elements (or into multiple spaces located between multiple protruding elements). The wedge prevents the female fastener from rotating around the shaft in a direction towards the bottom portion of the male fastener.
摘要:
In a securing element (10) for connecting two parts, in particular for a screw connection, the securing element is ring-shaped. The securing element has an outer profile (11) along the outer diameter and an inner profile (12) along the inner diameter. The outer profile (11) and the inner profile (12) are both formed by a plurality of profile units. The number of profile units of the outer profile and the number of profile units of the inner profile correspond to the number of graduation marks at different scales according to the principle of a vernier scale, the number of profile units of the outer profile (11) differing by at least 1 from the number of profile units of the inner profile (12). In precisely one position, a profile unit of the outer profile (11; 111; 1011) is exactly opposite a profile unit of the inner profile (12; 112).
摘要:
Die Erfindung betrifft ein Halterungssystem für die Anordnung von Werkstücken, insbesondere aus Blech oder anderem Lagenmaterial hergestellten Formteilen, in einer Meßposition. Solche Halterungssysteme werden in der Automobilindustrie, insbesondere in den Entwicklungs- und Designabteilungen, im Rahmen der Vermessung von z.B. Karosserieteilen oder Fahrzeuginnenverkleidungen eingesetzt. Dabei wird das gehalterte Werkstück durch eine Längenmeßeinrichtung, z.B. eine Meßtaster aufweisende Koordinatenmeßeinrichtung, an interessierenden Stellen abgetastet. Das Halterungssystem nach der Erfindung ist gekennzeichnet durch Trägersäulen (3), die auf einer Basisplatte (1, 1a) von dieser vorstehend montierbar sind sowie auf den Trägersäulen angeordnete Trägerköpfe (5) für die Aufnahme des Werkstücks (6). Ein solches Halterungssystem erlaubt den Aufbau von Halterungen mit verringertem Aufwand bei verbesserter Varibilität.
摘要:
A screw threaded fastening includes a first member (10) with an external screw thread (24) and a second member (22) with a corresponding internal screw thread (23), a radial bore (40) being provided in the first member (10) and a corresponding axial extending radial aperture or recess (32), being provided in the second member (22), so that when the screw threads (24, 23) of the first and second members (10, 22) engage and the second member (22) is tightened onto the first member (10), the radial bore (40) may be aligned angularly with the aperture or recess (32). A pin assembly (50) is provided, the pin assembly (50) comprising a pin (51) mounted on a spring element (53), the pin (51) being located in the radial bore (40) and being urged by the spring element (53) towards said aperture or recess (32), so that when the radial bore (40) is aligned angularly with the aperture or recess (32), the pin (51) will spring into the aperture or recess (32) preventing further relative rotation between the first and second members (10, 22).
摘要:
The invention concerns a nut provided with a locking element (4, 5, 6, 7), which by e.g. a screw (8, 9, 10, 11) can be urged radially against a screw thread. In order to provide a self-contained and easily releasable nut the locking element is arranged in a recess which, together with the element, is so arranged that at least a part (12, 13, 14, 15) of the element is deformed elastically when the element is moved against the screw thread. Thereby the element springs out of contact with the thread when the screw (8, 9, 10, 11) is released.

The present invention includes a fastener (300) comprising: a fastener body having a longitudinal axis (A-A') and a first external male threaded portion, and two or more through-holes perpendicular (312a, 312b) to the longitudinal axis of the fastener body in the threaded portion.
摘要:
The present disclosure includes a wheel assembly having a tie bolt retention system. Tie bolt retention systems of the present disclosure include retention holes 214 and retention elements 216. Retention elements may engage retention holes to prevent loosening or disengagement of a tie nut from the tie bolt.
