Description

La présente invention a trait à des perfectionnements apportés aux engins cylindriques à axe de rotation horizontal ou faiblement incliné, tels que, par exemple, à titre non limitatif, les broyeurs à ciment ou clinker, les broyeurs à boulets,les mélangeurs et les bouleteurs, ainsi que les cylindres à diffusion continue, etc.; elle concerne particulièrement de tels engins qui comprennent une virole cylindrique reposant sur des lignes de rouleaux-moteurs, dont l'axe est parallèle à l'axe longitudinal de la virole, et qui servent à la fois de support et de moyen d'entraînement de la virole.The present invention relates to improvements made to cylindrical machines with a horizontal or slightly inclined axis of rotation, such as, for example, without limitation, cement or clinker mills, ball mills, mixers and pelletizers, as well as continuous diffusion cylinders, etc .; it particularly relates to such machines which comprise a cylindrical shell resting on lines of motor rollers, the axis of which is parallel to the longitudinal axis of the shell, and which serve both as a support and as a drive means for the ferrule.

Une disposition générale d'un engin du type défini ci-dessus est décrite par exemple dans le brevet FR t567267.A general arrangement of a machine of the type defined above is described for example in patent FR t567267.

Le brevet français FR 75 05141 (No. de publication:2292521) décrit par ailleurs un rouleau-moteur pour l'application susvisée constitué d'un moteur électrique à deux bouts d'arbre attaquant à chaque bout au moins une roue faisant office de rouleau pour le support et l'entraînement de la virole de l'engin.French patent FR 75 05141 (Publication no .: 2292521) further describes a motor roller for the above-mentioned application consisting of an electric motor with two shaft ends driving at each end at least one wheel acting as a roller. for the support and training of the shell of the vehicle.

La présente invention concerne plus particulièrement une nouvelle conception des rouleaux-moteurs, qui permet, outre une exécution aisée, un montage ou un démontage facile et rapide.The present invention relates more particularly to a new design of the motor rollers, which allows, in addition to easy execution, easy and quick assembly or disassembly.

Selon la présente invention, le rouleau-moteur pour le support et l'entraînement de la virole cylindrique d'un engin rotatif à axe horizontal ou faiblement incliné reposant sur des lignes de rouleaux-moteurs dont l'axe est parallèle à l'axe longitudinal de la virole, est caractérisé en ce qu'il comprend un chassis muni d'une fusée fixe en porte-à-faux, dans laquelle est logé le moteur d'entraînement, supportant un réducteur de vitesse monté en bout d'arbre du moteur, et pourvue d'un chemin de roulement extérieur autour duquel tourne une jante entraînée par un flasque solidaire de l'arbre du réducteur de vitesse.According to the present invention, the motorized roller for supporting and driving the cylindrical shell of a rotary machine with a horizontal or slightly inclined axis resting on lines of motorized rollers whose axis is parallel to the longitudinal axis of the ferrule, is characterized in that it comprises a chassis provided with a fixed cantilever rocket, in which is housed the drive motor, supporting a speed reducer mounted at the end of the motor shaft , and provided with a external raceway around which rotates a rim driven by a flange secured to the speed reducer shaft.

L'invention sera explicitée dans la description qui va suivre en référence aux dessins annexés qui représentent un exemple de réalisation d'un rouleau-moteur pour le support et l'entraînement d'une virole cylindrique mettant en oeuvre les caractéristiques de la présente invention. Ces dessins représentent respectivement en figure 1, une vue longitudinale en coupe et en figure 2, une vue en bout, d'un rouleau-moteur.The invention will be explained in the description which follows with reference to the appended drawings which show an embodiment of a motorized roller for the support and the drive of a cylindrical shell implementing the characteristics of the present invention. These drawings respectively represent in Figure 1, a longitudinal sectional view and in Figure 2, an end view of a motor roller.

En référence aux dessins, 1 désigne le châssis du rouleau-moteur qui supporte une fusée cylindrique 2. Le châssis 1 comprend deux flas- ques latéraux 3 et 4 qui forment une carcasse extérieure partielle pour le rouleau moteur. A l'intérieur de la fusée 2 se trouve un moteur électrique 5 fixé à cette fusée 2 par un flasque 6.Referring to the drawings, 1 denotes the frame of the motor-roller which supports a cylindrical knuckle 2. The frame 1 comprises two flas - side c 3 and 4 forming a partial outer casing for the driving roller. Inside the rocket 2 is an electric motor 5 fixed to this rocket 2 by a flange 6.

Un réducteur planétaire 7 est également fixé sur la fusée 2 de façon à embrayer avec le bout d'arbre du moteur électrique 5.A planetary reduction gear 7 is also fixed on the rocket 2 so as to engage with the shaft end of the electric motor 5.

La fusée 2 est munie d'un chemin de roulement extérieur formé d'un double jeu de roulements 8 et 9; ces roulements supportent une jante métallique 10 dont une portion entoure la fusée 2. Sur la jante métallique 10 sont fixées des frettes métalliques 11, qui sont recouvertes à leur surface extérieure d'un revêtement élastique 12, destiné à entrer en contact avec la surface de la virole cylindrique devant être supportée et entraînée par le rouleau-moteur.The rocket 2 is provided with an external raceway formed by a double set of bearings 8 and 9; these bearings support a metal rim 10, a portion of which surrounds the rocket 2. On the metal rim 10 are fixed metal hoops 11, which are covered on their outer surface with an elastic coating 12, intended to come into contact with the surface of the cylindrical shell to be supported and driven by the motor roller.

Un flasque circulaire 13 calé sur le bout d'arbre du réducteur planétaire 7 est solidaire à sa périphérie de la jante métallique 10 et entraîne celle-ci .A circular flange 13 wedged on the shaft end of the planetary reducer 7 is integral at its periphery with the metal rim 10 and drives the latter.

On voit facilement que le rouleau-moteur suivant la présente invention est d'un montage et d'un démontage particulièrement faciles et que l'on peut remplacer aisément et rapidement soit le moteur d'entraînement, soit le réducteur planétaire. Il présente en outre l'avantage d'être réalisé suivant un ensemble très compact.It is easy to see that the motor roller according to the present invention is of a particularly easy assembly and disassembly and that one can replace easily and quickly either the drive motor or the planetary reducer. It also has the advantage of being produced according to a very compact assembly.

Il est évident que la forme de réalisation décrite ci-dessus constitue un exemple non limitatif et que des variantes peuvent être apportées sans sortir du cadre de la présente invention.It is obvious that the embodiment described above constitutes a nonlimiting example and that variants can be made without departing from the scope of the present invention.
