Abstract
Description
La présente invention concerne un ensemble en acier composé de trois éléments 1, 2 et 3, servant à faciliter le montage entre l'arbre d'entraînement et, soit un pignon 9, une poulie 9 ou un manchon d'accouplement 9. The present invention relates to a steel assembly composed of three elements 1, 2 and 3, serving to facilitate mounting between the drive shaft and either a pinion 9, a pulley 9 or a coupling sleeve 9.
Les trois éléments de cet ensemble sont en acier, fabriqués au tour et à la rectifieuse. L'ensemble est monté sur l'axe 4 (Fig. 1). The three elements of this set are made of steel, produced by lathe and grinding machine. The assembly is mounted on axis 4 (Fig. 1).
Sur l'axe 4, un élément 1, conique à l'extérieur au milieu et aux deux extrémités filetées 5 et 6, au pas à droite de 150 pour des arbres inférieurs à 40mm et au pas de 200mm aux extrémités 5 et 6 pour le montage sur des axes supérieur à 40mm. Le cône 7 est le même que les outils,mèches ou forets " cône mors N 6 à 1 degré 29mn " (Fig. 1). On axis 4, an element 1, conical on the outside in the middle and at the two threaded ends 5 and 6, at the right step of 150 for shafts less than 40mm and at the pitch of 200mm at the ends 5 and 6 for mounting on axes greater than 40mm. The cone 7 is the same as the tools, bits or drills "jaw cone N 6 at 1 degree 29mn" (Fig. 1).
L'alésage sur l'élément 1 peut aller de 20 à lOOmm en fabrication courante et plus, sur demande. (Fig. 1). The bore on the element 1 can range from 20 to 100 mm in current production and more, on request. (Fig. 1).
L'élément i qui s'emboîte sur l'arbre 4 est conique au milieu à l'extérieur, au même angle que le cône 7. L'élément 2 est conique à l'intérieur et cylindrique à l'extérieur aux dimensions normalisées des moyeux de poulies 9, pignons 9 ou manchons 9. Cette dimension peut aller de 30mm à 130mm ou plus sur demande. (Fig. 1). The element i which fits on the shaft 4 is tapered in the middle outside, at the same angle as the cone 7. The element 2 is tapered inside and cylindrical outside with the standardized dimensions of pulley hubs 9, pinions 9 or sleeves 9. This dimension can range from 30mm to 130mm or more on request. (Fig. 1).
Sur le filetage des extrémités 5 et 6 sont vissés deux élémentsécrous 3 avec des créneaux 12 (Fig. 1 et 4) pour la clé de serrage ou desserrage. On the threads of the ends 5 and 6 are screwed two nut elements 3 with slots 12 (Fig. 1 and 4) for the tightening or loosening wrench.
Le montage est effectué de la façon suivante: sur l'arbre 4 est monté l'élément 1 après avoir, au préalable, placé un élément-écrou 3 sur le filetage 6 pour le cas où celui-ci ne pourrait pas être placé après (c'est le cas des arbres de moteurs électriques). The assembly is carried out as follows: on the shaft 4 is mounted the element 1 after having previously placed a nut element 3 on the thread 6 for the case where it could not be placed after ( this is the case for electric motor shafts).
Il convient de veiller à ce que la partie la plus petite de l'élément 1 soit bien à l'avant du bout de l'arbre 4 par lequel est emmanché le pignon 9 ou le manchon 9 ou la poulie 9. L'élément 2 est rentré sur l'élé- ment 1. L'élément-écrou 3 est placé sur le filetage 5. It should be ensured that the smallest part of the element 1 is well in front of the end of the shaft 4 by which the pinion 9 or the sleeve 9 or the pulley 9 is fitted. The element 2 has entered the element 1. The nut element 3 is placed on the thread 5.
Les deux éléments 1 et 2 sont fendus sur leur longueur par une fente 8 de 2mm (Fig. 2 et 3) pour les arbres de 20 à 40 sans clavette. The two elements 1 and 2 are split along their length by a 2mm slot 8 (Fig. 2 and 3) for shafts from 20 to 40 without key.
Une fente 10 (Fig. 6 et 7) plus large pour les arbres de plus de 4o, de la largeur des dimensions des clavettes 11 normalisées (Fig. 5). Dans ce cas, l'arbre 4 comporte un emplacement de clavette normalisée.A wider slot 10 (Fig. 6 and 7) for shafts larger than 40, the width of the dimensions of the standard keys 11 (Fig. 5). In this case, the shaft 4 has a standardized key location.
L'ensemble faisant l'objet de la présente invention peut recevoir des surcharges, des chocs, des inversions de marche brutales. The assembly which is the subject of the present invention can receive overloads, shocks, sudden reversals of operation.
Après avoir placé l'élément 1, l'élément 2 et la poulie 9 ou le manchon 9 ou le pignon 9, on place l'élément-écrou 3 sur le filetage 5 qu'on visse jusqu a serrage. Le deuxième élément-écrou 3, placé sur le filetage 6 est serré. L'élément-écrou 3 sur filetage 5 pousse l'élément 2 qui stagrandit dans le moyeu 9 et se serre sur l'élément 2 qui lui-même se serre sur l'arbre 4. After placing the element 1, the element 2 and the pulley 9 or the sleeve 9 or the pinion 9, the nut element 3 is placed on the thread 5 which is screwed until tight. The second nut element 3, placed on the thread 6 is tightened. The nut element 3 on thread 5 pushes the element 2 which expands in the hub 9 and is tightened on the element 2 which itself is tightened on the shaft 4.
Lorsque l'élément-écrou 3 est bien serré et bloqué sur le filetage 5, on monte l'élément-écrou 3 qui avait été placé en attente sur le filetage 6. L'élément-écrou 3 est serré pour empêcher le déblocage des éléments 1 et 2 ; il sert à repousser l'élément 2 au démontage. When the nut element 3 is properly tightened and locked on the thread 5, the nut element 3 which had been placed on standby on the thread 6 is mounted. The nut element 3 is tightened to prevent the elements from being released. 1 and 2 ; it is used to repel element 2 during disassembly.
Le démontage est effectué de la façon suivante: ltélément-écrou 3 de blocage est retiré du filetage 5. Le deuxième élément-écrou 3 est bloqué sur le filetage 6. il va repousser l'élément 2, libérant en même temps la poulie 9, ou le pignon 9 ou le manchon 9 et l'arbre 4. Disassembly is carried out as follows: the locking element nut 3 is removed from the thread 5. The second nut element 3 is blocked on the thread 6. it will push the element 2, simultaneously releasing the pulley 9, or the pinion 9 or the sleeve 9 and the shaft 4.
Aucune préparation n'est nécessaire pour assembler les pignons 9 ou les poulies 9 ou les manchons 9 ainsi que les arbres 4. No preparation is necessary to assemble the pinions 9 or the pulleys 9 or the sleeves 9 as well as the shafts 4.
