ROTOR BEARING FOR A WIND TURBINE, COMPRISING A DOUBLE, MULTI-ROW ROLLING BEARING WITH THREE CONCENTRIC BEARING RINGS

摘要

The invention relates to a rotor bearing (1) for a wind turbine, comprising an inner ring (83), which is or can be rotationally fixed to a first rotational partner, an outer ring (5), which likewise is or can be rotationally fixed to the first rotational partner and an intermediate ring (4), which is or can be rotationally fixed to a second rotational partner. According to the invention, the inner ring (3) is mounted to rotate in relation to the intermediate ring (4) by means of at least one inner rolling body row (7) and the outer ring (5) is mounted to rotate in relation to the intermediate ring (4) by means of at least one outer rolling body row (6).
