Yaw assembly for a wind turbine

A yaw assembly for a wind turbine, comprising:

• a yaw piston;
• a yaw pad having a first side configured for engagement with a slew ring of the wind turbine and a second side configured for engagement with the yaw piston;
• a thrust stem disposed within the yaw piston and configured to apply force to the yaw pad against the slew ring, the thrust stem biased away from the yaw pad by one or more springs residing within the yaw piston;
• a threaded bushing configured for threading into a yaw cylinder containing the yaw piston;
• an anti-rotation collar disposed between the one or more springs and the yaw piston;
• and
• at least three force adjustment members disposed through the threaded bushing and engageable with the thrust stem for applying a force thereto, each of the force adjustment members movable and lockable relative to the threaded bushing for adjustment of the force applied to the thrust stem against a biasing of the one or more springs.

• an anti-rotation collar disposed between the one or more springs and the yaw piston;
• and
• at least three force adjustment members disposed through the threaded bushing, each of the force adjustment elements movable and lockable relative to the threaded bushing, where movement of the force adjustment members adjusts a force applied to the thrust stem when the threaded bushing is threaded into the yaw cylinder.

• a threaded bushing configured for threading into a yaw cylinder containing the yaw piston;
• a channel disposed through the threaded bushing, the channel configured to receive a lubricant therein for lubricating one or more components of the yaw assembly;
• and
• at least three force adjustment members disposed through the threaded bushing and engageable with the thrust stem for applying a force thereto, each of the force adjustment members movable and lockable relative to the threaded bushing for adjustment of the force applied to the thrust stem against a biasing of the one or more springs.
