Definitions

  • the invention accordingly relates to a method for securing against inadvertent loosening or loosening of through-bolts, screws or bolts firmly connected to the workpiece, or workpieces whose ends or ends are designed like screws or threaded bolts, with a hexagon (polygonal) fastening nut in any position, whether screwed tight or not.
  • the invention is particularly based on the object, a tightened with the appropriate torque Allen screw with hexagon (polygon) - fastening nut with any position of the hexagon (polygon) of the fastening nut easy, inexpensive and absolutely reliable to secure without additional auxiliary bores, auxiliary tapped holes or other reworking on the workpiece, whereby the parts that effect the securing are light and easy usual tools to assemble or disassemble and can be used again.
  • the method according to the invention for securing through-bolts with hexagon (polygonal) fastening nut and a hexagon (polygonal) securing nut which deviates therefrom is characterized in that the standard screw which is to be secured in its position additionally has a threaded shoulder at the end of its threaded shaft, which has a smaller thread of corresponding length and with an opposite direction of rotation (preferably to the left) in relation to the diameter of the screw.
  • both nuts namely fastening nut (preferably right-hand thread) and locking nut (then left-hand thread) on the one hand, and the fastening screw on the other hand are secured against twisting against one another and thus unintentional loosening. Since, according to the invention, as mentioned, the commercially available fastening screw at the shaft end, in addition to the fastening thread, has a thread attachment that is opposite to the fastening thread, this would result in a theoretical loosening
  • This figure shows a hexagon through screw 1 with reworked shaft in the screwed and secured state.
  • the through screw 1 preferably has a right-hand thread; her reworked Then left-handed thread.
  • the core thread diameter of the fastening thread is larger than the nominal thread diameter of the securing thread, so as not to prevent the fastening nut 2 from being screwed on. e.g. screw 1 M20, locking thread M16 x 2 left.
  • screw 1 M20 nominal thread diameter of the securing thread
  • locking thread M16 x 2 left e.g. screw 1 M20, locking thread M16 x 2 left.
  • a necessary preparatory work on the fastening screw 1 therefore consists in that at the shaft end of the fastening screw 1 a corresponding direction of rotation opposite to the fastening thread, the fastening nut 2 is cut as the diameter does not hinder the screwing up (turning off to the corresponding diameter and thread ).
  • Fig. 2 shows a storage example in the set and secured state. (Turned part or axle 1 ', adjusting nut 2', lock nut 3 and locking plate 4)

Abstract

Système de fixation simple, fiable, montable et démontable aisément pour un boulon traversant (1) comportant un écrou (2) hexagonal (multipan) et, à l'extrémité de sa tige filetée, un filetage supplémentaire plus petit tournant dans le sens opposé. L'écrou de blocage (3), dont le sens de rotation est opposé à celui de l'écrou de fixation (2), et une tôle de fixation annulaire (4) bloque l'écrou de fixation (2) et l'écrou de blocage (3) l'un contre l'autre, empêchant ainsi leur rotation, de sorte que finalement le boulon traversant ou le boulon de fixation (1) ne peut absolument pas non plus se desserrer accidentellement. Puisque même des assemblages qui n'ont pas été vissés à fond peuvent être bloqués avec ce système, d'autres applications sont possibles, notamment pour régler le jeu des coussinets (par exemple dans des roulements à rouleaux coniques) ou bien pour la fixation (par exemple effets de ressort).
