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.
