Yaw bearing assembly for use with a wind turbine and a method for braking the yaw movement

摘要

A yaw bearing assembly (72, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000) is disclosed that includes a first component having a first sliding surface (82) and a second sliding surface (120), and a brake assembly coupled with respect to the first component and adjacent to at least one of the first sliding surface and the second sliding surface. The brake assembly a piston (140, 534, 638, 734, 842, 930, 1034), a sliding pad (84) coupled to the piston, and an activation device (86, 148, 202, 302, 402, 532, 636, 732, 840, 944, 1032) coupled to the piston for moving the sliding pad with respect to at least one of the first sliding surface and the second sliding surface.
