Abstract

Eine füllstücklose Innenzahnradmaschine mit einem Gehäuse (1), einem in einer Bohrung (15) des Gehäuses quer zu seiner Achse bewegbar, jedoch undrehbar aufgenommenen Lagerring (4), einem in dem Lagerring umlaufend gelagerten innenverzahnten Hohlrad (3) und einem in dem Gehäuse drehbar gelagerten Ritzel (2). Der Lagerring ist relativ zu der Gehäusebohrung (15) um eine zu seiner Achse parallele Schwenkachse (16,17) schwenkbar. Die Schwenkachse liegt so, daß der dem eingriffsfreien Hohlradbereich zugeordnete Ringabschnitt des Lagerrings (4) durch die im Druckraum auf das Hohlrad wirkenden Druckkräfte (Resultierende R) zumindest annähernd radial zur Ritzelachse hin bewegt wird.

Figure 00000001
A filler-free internal gear machine with a housing (1), a bearing ring (4) which can be moved in a bore (15) of the housing transversely to its axis but is non-rotatably received, an internally toothed ring gear (3) which is mounted in the bearing ring and rotates in the housing stored pinion (2). The bearing ring can be pivoted relative to the housing bore (15) about a pivot axis (16, 17) parallel to its axis. The pivot axis is such that the ring section of the bearing ring (4) assigned to the non-engagement ring gear region is moved at least approximately radially towards the pinion axis by the pressure forces (resultant R) acting in the pressure chamber on the ring gear.
