Title (EN) GEAR PUMP
(FR) POMPE A ENGRENAGES
Abstract: front page image
(EN)The present invention relates to a gear pump which incorporates a ring gear (16) supported for rotation, a gearwheel (17) arranged eccentrically within the ring gear (16), and a rotatable shaft (9) incorporating a portion which extends through a hole (18) in the gearwheel. Said portion of the shaft (9) incorporates a first surface (21’), and the gearwheel incorporates a second surface (22’), which surfaces are so shaped as to allow transfer of rotary motion from the shaft (9) to the gearwheel (17). Said transfer between the first surface (21’) and the second surface (22’) takes place via a region of contact (a). The region of contact (a) has axial extent equal to less than half of the gearwheel’s axial extent (b) and is divided by a radial plane (c) which extends centrally through the gearwheel (17).
(FR)La présente invention concerne une pompe à engrenages comprenant une couronne (16) soutenue rotative, une roue d'engrenage (17) agencée excentrique à l'intérieur de la couronne (16), et un arbre rotatif (9) comprenant une partie qui s'étend à travers un trou (18) dans la roue d'engrenage. Ladite partie de l'arbre (9) comprend une première surface (21') et la roue d'engrenage comprend une seconde surface (22'), lesquelles surfaces possèdent une forme telle qu'elles permettent le transfert d'un mouvement rotatif de l'arbre (9) à la roue d'engrenage (17). Ledit transfert entre la première surface (21') et la seconde surface (22') s'effectue via une région de contact (a). La région de contact (a) possède une étendue axiale inférieure à la moitié de celle (b) de la roue d'engrenage, et est divisée par un plan radial (c) qui s'étend centralement à travers la roue d'engrenage (17).
