Abstract

La présente invention concerne un malaxeur à mélange forcé à deux arbres comprenant des unités d'appui (5b) et des engrenages planétaires (5a) rendus synchrones d'un point de vue mécanique, destinés à l'appui et à l'entraînement des arbres malaxeurs (9). Les boîtiers des unités d'appui (5b) et des entraînement (5a) présentent respectivement une bride de fixation grâce auxquelles lesdites unités d'appui et lesdits entraînements sont fixés avec un emplacement et une position précise contre le compartiment de malaxage (8) du malaxeur (1), au niveau de surfaces fonctionnelles (4a, 4b) correspondantes qui sont matérialisées par des ponts de fixation (2) disposés sur les côtés frontaux du malaxeur (1). Les ponts de fixation (2) sont traversés par des parties en saillie (6) qui sont formées par des nervures de tôle (3) disposées contre les parois frontales (11) du compartiment de malaxage (8), et lesdits ponts de fixation sont soudés, au niveau de ces emplacements de passage, avec les parties en saillie (6) des nervures de tôle (3). En raison de cette structure, il est possible de réaliser les ponts de fixation (2) séparément de la partie restante du compartiment de malaxage (8), déjà avec des surfaces fonctionnelles finies (4a, 4b), et de les placer, traversés par les parties en saillie (6), contre les côtés frontaux (11) de l'ébauche de compartiment de malaxage, de manière à les aligner et à les souder avec les nervures de tôle (3) au niveau de ces emplacements de passage. Cela permet de supprimer le traitement ultérieur du compartiment de malaxage (8) sur une machine-outil pour permettre la mise en place et le positionnement précis des surfaces fonctionnelles (4a, 4b), ce qui permet une nette diminution du temps et des frais nécessaires à la réalisation d'un malaxeur à mélange forcé à deux arbres (1).
