high-pressure gear inside machine with a multiple hydrostatic bearing per ring gear

摘要

high-pressure gear inside machine, in particular internal gear pump (10), with a housing (11), a in the housing (11) rotatably mounted, externally toothed pinion (12) and a with the pinion (12) control, as well as in the housing (11), which is mounted to rotate with the pinion (12) meshing, internally toothed ring gear (13), wherein, in any one of a radially outwardly directed circumferential surface (14) of the internal gear wheel (13) opposite housing part (15) and / or bearing part with a plurality of, for which is open toward the ring gear (13) and by means of sealing webs (17.1 to 17.8) limited pressure pockets (18.1, 18.2) for the hydrostatic bearing of the in one piece and / or integrally formed ring gear (13) are provided, characterized in that the the pressure pockets (18.1, 18.2) sealing webs (17.1 to 17.8) with to the ring gear (13) is open towards the relief grooves (23.1, 23.2, 23.3, 23.4) are provided which, in a common, in the axial direction (19) and extending to the ring gear (13) is open towards the relief channel (24).
