Description

  

  Dispositif pour éviter le desserrement d'organes tels que des écrous.    On sait que dans     certaines        machines    ayant  des     trépidations    les écrous sont fréquemment  desserrés. L'objet de la présente invention  est un dispositif pour éviter le     desserre-          inent    de tels organes.  



  Le dispositif consiste en un organe qui,  dans sa partie faisant contact avec la pièce  à fixer, est muni d'une creusure et de deux  encoches, dans lesquelles est placée une  rondelle. Cette rondelle porte des ailettes re  pliées sur la pièce à fixer. La creusure et les  encoches de l'organe et la rondelle encastrée  ont une forme telle qu'en serrant l'organe, la  rondelle est obligée à tourner avec cet or  gane,     tandis    que le desserrage de l'organe  est empêché par les ailettes formant arrêts  sur la pièce à fixer.  



  Le dessin ci-joint, donné à titre d'exem  ple, montre une forme d'exécution de l'objet  de     l'invention.     



  La     fig.    1 montre une élévation d'un écrou  avec la rondelle;  La     fig.    2 montre la     fig.    1, vue dans la       direction    de la flèche A;  La     fig.    3 montre la rondelle, vue de face;    La     fig.    4 montre la     fig.    3, vue dans la  direction de la flèche B;  La     fig:    5 montre une partie d'un boulon  muni du dispositif.  



       L'écrou    1 est muni dans la partie     q111    fait  contact avec la pièce à fixer d'une creusure  2 et de deux encoches 3. La rondelle 4, con  sistant en un matériel élastique, par exemple  en acier trempé, possède des ailettes 5 et a  un diamètre tel qu'elle peut être mise de  force dans la creusure 2, cependant que les  ailettes 5 sont placées dans les encoches 3.  



  Les ailettes 5 de la rondelle sont repliées  de manière que la rondelle reste plate dans  la creusure de l'écrou. En outre, les ailettes  sont pliées dans le sens     inverse    au serrage  de l'écrou. L'écrou oblige la rondelle de cette  manière à tourner avec lui. En serrant  l'écrou, les deux ailettes font ressort en glis  sant sur la pièce que l'on veut serrer,     .mais     au moment où l'on voudrait desserrer, une  farce beaucoup plus grande est nécessaire,  étant donné que les deux ailettes font arrêt.  Pour le desserrement il faut employer un .  instrument quelconque pour relever d'abord  les ailettes.      Les têtes des boulons, les vis,     été.    peu  vent: être préparées de la manière décrite.

         Dans    un boulon l'écrou et la tête du boulon  peuvent être creusés et munis chacun de  deux encoches pour recevoir des rondelles  décrites.



  Device to prevent the loosening of parts such as nuts. It is known that in certain machines having trepidations the nuts are frequently loosened. The object of the present invention is a device for preventing the loosening of such organs.



  The device consists of a member which, in its part making contact with the part to be fixed, is provided with a recess and two notches, in which a washer is placed. This washer carries fins bent on the part to be fixed. The recess and the notches of the organ and the recessed washer have a shape such that by tightening the organ, the washer is forced to rotate with this or gane, while the loosening of the organ is prevented by the fins forming stops on the part to be fixed.



  The accompanying drawing, given by way of example, shows an embodiment of the object of the invention.



  Fig. 1 shows an elevation of a nut with the washer; Fig. 2 shows fig. 1, viewed in the direction of arrow A; Fig. 3 shows the washer, seen from the front; Fig. 4 shows fig. 3, viewed in the direction of arrow B; Fig: 5 shows part of a bolt provided with the device.



       The nut 1 is provided in the part q111 makes contact with the part to be fixed with a recess 2 and two notches 3. The washer 4, consisting of an elastic material, for example of hardened steel, has fins 5 and has a diameter such that it can be forced into the recess 2, while the fins 5 are placed in the notches 3.



  The fins 5 of the washer are folded back so that the washer remains flat in the recess of the nut. In addition, the fins are bent in the opposite direction to the tightening of the nut. The nut forces the washer in this manner to rotate with it. When tightening the nut, the two fins spring up by sliding over the part that you want to tighten,. But when you want to loosen, a much larger stuffing is necessary, since the two fins are stop. For loosening it is necessary to use a. any instrument to first raise the fins. The heads of the bolts, the screws, were. little wind: be prepared as described.

         In a bolt the nut and the bolt head can be hollowed out and each provided with two notches to receive the washers described.
