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-desus est décrite par exemple dans le brevet français 1567267.A general arrangement of a machine of the type defined above is described for example in French patent 1567267.

Le document FR-A-2 292 521 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.The document FR-A-2 292 521 also describes a motor roller for the abovementioned 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 the drive of the shell of the craft.

D'autre part, le document DE-A-2 649 648 décrit un rouleau-moteur comprenant une fusée cylindrique montée en porte-à-faux sur un châssis entourée d'une jante rotative et renfermant un moteur, la jante rotative étant entraînée par un flasque relié au moteur et appuyant sur la fusée à l'aide d'un roulement.On the other hand, document DE-A-2 649 648 describes a motorized roller comprising a cylindrical spindle mounted in cantilever on a chassis surrounded by a rotary rim and enclosing a motor, the rotary rim being driven by a flange connected to the engine and pressing the rocket using a bearing.

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 que la fusée cylindrique fixée au châssis est ouverte du côté du châssis où le moteur est fixé sur la fusée à l'aide d'un flasque et est ouverte côté porte-à-faux où un réducteur est fixé sur la fusée, en ce que la jante est supportée par l'intermédiaire d'un double jeu de roulements par la fusée et en ce que le flasque entraînant la jante est relié au bout d'arbre du réducteur.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 shell, is characterized in that the cylindrical rocket fixed to the chassis is open on the side of the chassis where the engine is fixed to the rocket by means of a flange and is open on the overhang side where a reduction gear is fixed on the spindle, in that the rim is supported by means of a double set of bearings by the spindle and in that the flange driving the rim is connected to the end of the reduction gear 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 réference aux dessins, 1 désigne un châssis du rouleau-moteur qui supporte en porte-à-faux une fusée cylindrique 2 ouverte de part et d'autre. Le châssis 1 comprend deux flasques latéraux 3 et 4 qui forment une carcase extérieure partielle pour le rouleau moteur. A l'intérieur de la fusée 2, côté châssis, se trouve un moteur électrique 5 fixé latéralement à cette fusée 2 par un flasque 6.With reference to the drawings, 1 designates a chassis of the drive roller which supports a cantilever rocket 2 open on either side. The chassis 1 comprises two lateral flanges 3 and 4 which form a partial external carcase for the drive roller. Inside the rocket 2, on the chassis side, is an electric motor 5 fixed laterally to this rocket 2 by a flange 6.

Un réducteur planétaire 7 est également fixé sur la fusée 2, côté porte-à-faux, de façon à embrayer avec le bout d'arbre du moteur electrique 5.A planetary reduction gear 7 is also fixed on the spindle 2, on the overhang side, 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 un 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, sans enlever la charge constituée par une virole, non représentée, sur la jante 10, soit d'un côté le moteur d'entraînement, soit de l'autre côté le réducteur planétaire. Il présente en outre l'avantage d'être réalisé suivant un ensemble très compact.It can easily be seen that the motor roller according to the present invention is of particularly easy assembly and disassembly and which can be replaced quickly and easily, without removing the load constituted by a ferrule, not shown, on the rim 10, either on one side the drive motor, or on the other side the planetary reducer. It also has the advantage of being produced according to a very compact assembly.
