Large bearing, especially a main bearing for a wind turbine, as well as a wind turbine with such a large bearing

摘要

Main bearing for a wind turbine, with two components (1,2) mounted next to each other at least through a rolling bearing (3), namely a rotor (1) and a stator (2), presenting at least one rolling bearing (3), a set of rolling bodies (3a) having a plurality of rolling bodies, characterized in that at least one set of rolling bodies (3a) is supported, on both components (1, 2), directly and without a separate bearing ring, against a raceway (5, 6) which is an integral part of the respective component (1, 2), and because the rotor (1) and the stator (2) are supported by two mutually spaced rolling bearings (3), forming only a separate bearing ring (6) or a preloaded ring (20) with a raceway integrated in one of the two raceways (3), which is adjustable to generate a bearing preload
