Abstract

Die Erfindung betrifft eine Rotorlagerung für eine Windenergieanlage (1), im Wesentlichen bestehend aus einem drehbar auf einem Maschinenturm (2) gelagerten Maschinenhaus (3) mit einem Generator (4) zur Stromerzeugung, einem windgetriebenen Rotor (5) mit einer mindestens zwei Rotorblätter (6) tragenden Rotornabe (7) und einem den Rotor (5) tragenden Großwälzlager (8), das einen drehfest am Maschinenhaus (3) befestigten und koaxial zur Rotornabe (7) angeordneten ersten Lagerring (9) sowie einen verdrehbar am ersten Lagerring (9) gehaltenen und an der Rotornabe (7) befestigten zweiten Lagerring (10) sowie eine Vielzahl zwischen den Lagerringen (9, 10) abrollender Wälzkörper (11) aufweist und mit einem nachgeschalteten, mit dem Generator (4) verbundenen Planetengetriebe (12) in Verbindung steht, das aus einem Hohlrad (13) mit einer umlaufenden Innenverzahnung (14), mehreren auf Planetenträgern (15) gelagerten Planetenrädern und aus einem zentralen Sonnenrad besteht. Erfindungsgemäß bildet der radial innere der beiden Lagerringe (9 oder 10) des Großwälzlagers (8) zugleich das Hohlrad (13) des mit dem Generator (4) verbundenen Planetengetriebes (12), indem dessen Innenseite (16) mit der umlaufenden Innenverzahnung (14) des Hohlrades (13) ausgebildet ist.
