  "ASSEMBLAGE A VIS INDE3SERRABLE" 
L'invention concerne un assemblage à vis indesserrable   @   et elle comporte le dispositif connu par lequel le contre- écrou est maintenu par une plaque de verrouillage   comportant   des appendices s'entgageant dans des fented du boulon. 



   Ces fentes du boulon ont des inconvénients, parce que le boulon perd de sa solidité. En outre. il peut arriver   très     faciles!   que la partie filetée soit repliée par dessus ces; fentes, de sorte qu'un écrou ne tient plus du tout sur le boulon. 



   Suivant l'invention, on évite ces inconvénients en ne pratiquant que des rainures au lieu de fentes dans le boulon. 



  Toutefois, et ceci est l'idée principale de l'invention,   ces .   rainures n'ont qu'une longueur telle que la partie principale , du boulon principal travaille en majeure partie sur un filet.; 

 <Desc/Clms Page number 2> 

 non entamé d'un boulon dont la section   n'a,   pas changé. 



   Au-dessus de l'écrou principal, c'est-à-dire dans la partie du boulon soulagée des efforts de l'assemblage à vis, sont pratiquées deux ou trois courtes rainures dans lesquelles s'engagent les appendices d'une plaque de   verrouillage.   Cette plaque de verrouillage est posée sur l'écrou principal et on visse ensuite un écrou auxiliaire dont le diamètre est de pré- férence plus petit et que joue le rôle de contre-écrou bloqué par le repli de l'arête de la plaque de verrouillage. 



   Le dessin représente à titre d'exemple un mode de réali- sation du nouvel assemblage à vis indcesserrable. 



   La Fig. 1 est un plan de cet assemblage. 



   La Fig. 2 est une coupe longitudinale de la Fig. 1'. 



   La Fig. 3.est une vue en plan et en coupe de la plaque de verrouillage. 



   La Fig. 4 est une coupe par la ligne 4-4 de la Fig 3. 



   La plaque de verrouillage d est engagée par-dessus le boulon b, les extrémités des appendices f coulissant dans les fentes ou rainures latérales 4 du boulon et la plaque de verrouillage d. reposant sur l'écrou serré c de façon que   le   bord relevé g de la plaque de   verrouillage   soit dirigé vers l'extrémité fendue du boulon b. La bague taraudée a qui com- porte par exemple une arête extérieure est vissée sur le boulon b contre la plaque de verrouillage d et bloquée par le fait que le bord relevé g de la plaque de   verrouillage d.   est   appli-   qué en totalité ou en partie sur le pourtour de la bague ta- raudée a par un choc ou une pression. 



   Pour desserrer ou resserrer l'assemblage a vis, on re- dresse le bord appliqué g de la plaque de verrouillage d en faisant tourner la bague taraudée a.

  "INDE3SERRABLE SCREW ASSEMBLY"
The invention relates to an unbreakable screw connection @ and it comprises the known device by which the lock nut is held by a locking plate comprising appendages engaging in slots in the bolt.



   These bolt slots have drawbacks, because the bolt loses its strength. In addition. it can happen very easy! that the threaded part is folded over these; slots, so that a nut does not fit on the bolt at all.



   According to the invention, these drawbacks are avoided by making only grooves instead of slots in the bolt.



  However, and this is the main idea of the invention, these. grooves are only as long as the main part, the main bolt mostly works on a thread .;

 <Desc / Clms Page number 2>

 not started with a bolt whose cross-section has not changed.



   Above the main nut, that is to say in the part of the bolt relieved of the forces of the screw connection, are made two or three short grooves in which the appendages of a plate engage. locking. This locking plate is placed on the main nut and an auxiliary nut is then screwed, the diameter of which is preferably smaller and which acts as a lock nut blocked by the bending of the edge of the locking plate. .



   The drawing shows, by way of example, one embodiment of the new locking screw connection.



   Fig. 1 is a plan of this assembly.



   Fig. 2 is a longitudinal section of FIG. 1 '.



   Fig. 3. is a plan and sectional view of the locking plate.



   Fig. 4 is a section through line 4-4 of Fig 3.



   The locking plate d is engaged over the bolt b, the ends of the appendages f sliding in the side slots or grooves 4 of the bolt and the locking plate d. resting on the tightened nut c so that the raised edge g of the locking plate faces towards the slotted end of the bolt b. The threaded ring a which has for example an outer edge is screwed onto the bolt b against the locking plate d and blocked by the fact that the raised edge g of the locking plate d. is applied in whole or in part to the periphery of the threaded ring a by an impact or pressure.



   To loosen or tighten the screw assembly, the applied edge g of the locking plate d is straightened by rotating the threaded ring a.

RESUME. ABSTRACT. Assemblage à vis indesserrable comportant une plaque de verrouillage, caractérisé en ce que les -rainures pratiquées dans le boulon pour le blocage de la plaque de verrouillage ne sont pratiquées que dans la partie supérieure du boulon, de sorte que l'écrou principal travaille dans une partie non affaiblie du boulon, la plaque de verrouillage compo!'tant deux ou trois appendicaescorrespondant aux rainures du boulon blo- quant un petit contre-écrou. Locking screw connection comprising a locking plate, characterized in that the grooves made in the bolt for locking the locking plate are only made in the upper part of the bolt, so that the main nut works in a un weakened part of the bolt, the locking plate consists of two or three appendages corresponding to the grooves of the bolt securing a small locknut.
