Abstract
L'invention concerne un dispositif d'entraînement à broche fuletée avec système de décharge hydrostatique. Ce dispositif est caractérisé en ce que la pompe à huile sous pression 4 est fixée sur la noix 2 et est entraînée par un pignon d'attaque 17 qui est en prise avec la denture intérieure 15 d'une couronne dentée 14 disposée concentriquement à la noix 2, montée à rotation sur celle-ci, pourvue d'une denture intérieure 15 et d'une denture extérieure 16 et qui peut être entraînée indépendamment du mécanisme d'entraînement en rotation 34 par l'intermédiaire d'un engrenage 19 en prise avec sa denture extérieure 16. L'invention s'applique à des mécanismes d'entraînement.
