Abstract

L'invention vise à créer un mécanisme d'entraînement d'un engin de levage, qui soit plus compact qu'actuellement et dont la conception permette l'utilisation répétée de composants identiques et la suppression des composants typiques de la construction électromécanique et jusque là indispensables, ainsi que l'augmentation de la durée de vie du mécanisme d'entraînement de l'engin de levage. Le mécanisme d'entraînement compact, sans engrenage de transmission et à rotor extérieur de l'engin de levage a une construction mécanique, de préférence, symétrique. Le rotor extérieur (1) est composé d'un tube d'entraînement (2) auquel sont fixées des pièces tubulaires coudées (3). Ces pièces tubulaires coudées (3) sont flanquées des deux paliers principaux (4) qui, à leur tour, sont maintenus respectivement par une bague support de palier (5). Chaque bague support de palier (5) possède une liaison avec l'embase (6) du mécanisme d'entraînement de l'engin de levage. Le stator (7) du moteur électrique et son arbre (8) sont, d'un côté, solidement reliés à un capot porteur (9). Le capot porteur (9) a une liaison avec la bague support de palier (5) associée. L'arbre (8) du stator est, de l'autre côté, monté dans une plaque terminale (10) interne. Cette plaque terminale (10) est reliée à la pièce tubulaire coudée (3) associée au tube d'entraînement (2). Une plaque terminale (11), externe parallèle à la plaque terminale (10) interne, est fixée à la face externe de la bague de support de palier (5).
