Abstract

Pompe hydraulique améliorée pour entrainement à haute vitesse Ensemble comprenant une pompe hydraulique (100) et un réducteur (200) épicycloïdal, dans lequel la pompe hydraulique (100) est une pompe hydraulique à pistons radiaux, le réducteur (200) comprenant un planétaire extérieur (210), un planétaire intérieur (220), un porte satellite (230) et un satellite (240) ; caractérisé en ce que le réducteur (200) étant logé dans le volume interne du carter (110) de la pompe hydraulique (100), le planétaire extérieur (210) du réducteur (200) est solidaire du carter (110) de la pompe hydraulique (100), le planétaire intérieur (220) est solidaire de l’arbre (120) de la pompe hydraulique (100), et le porte satellite (230) est solidaire du bloc cylindres (130) de la pompe hydraulique (100), de manière à ce que le réducteur (200) applique un rapport de réduction entre l’arbre (120) et le bloc cylindres (130) de la pompe hydraulique (100). Figure pour l’abrégé : Fig. 1.Improved hydraulic pump for high speed drive Assembly comprising a hydraulic pump (100) and an epicyclic reducer (200), wherein the hydraulic pump (100) is a radial piston hydraulic pump, the reducer (200) comprising an outer sun gear (210), an inner sun gear (220), a planet carrier (230) and a satellite (240); characterized in that the reducer (200) being housed in the internal volume of the casing (110) of the hydraulic pump (100), the outer planetary (210) of the reducer (200) is integral with the casing (110) of the hydraulic pump (100), the inner planetary (220) is integral with the shaft (120) of the hydraulic pump (100), and the satellite carrier (230) is integral with the cylinder block (130) of the hydraulic pump (100), so that the reducer (200) applies a reduction ratio between the shaft (120) and the cylinder block (130) of the hydraulic pump (100). Figure for abstract: Fig. 1.
