Rotor bearing of wind turbine, has two rows of bearings that are formed by self aligning the self-aligning ball bearing and arranged about bearing axis for rolling off rolling elements

摘要

The rotor bearing (9) has two rows of bearings (13,14) that are arranged about a bearing axis (15) for rolling off the rolling elements. The rows of bearings are arranged symmetrically and axially with respect to pressure line (16). The two rows of bearings are formed by self aligning the self-aligning ball bearing.
