The primary mechanical parts of the Yaw System are This section provides information about the relationship of the yaw bearing, yaw ring, and brakes. Yaw rings The yaw ring is a large gear that engages the pinion gears of the yaw motor gearboxes. Because these gears carry high loads, proper lubrication is important to prevent…

Heat is generated during the operation of the gearbox due to friction between the solid surfaces of the moving parts. Most of the heat is generated by the friction between the gear teeth, and between the rollers and rings of the bearings. Depending on the type of the engaging gears, the input torque and speed,…
