Wind Turbine Gearbox Vibration Analysis
When a gearbox vibrates as a whole, the severity of the vibration can be detected at the outer surface of the gearbox housing. While some vibration is normal, higher levels of vibration can be caused by the wearing or failure of the gearbox components. For this reason, gearboxes often incorporate vibration sensors to detect conditions…
Wind Turbine Yaw Gearbox
Power from the yaw motors is transmitted to the yaw ring through a reduction gearbox which provides both speed reduction and torque multiplication. This yaw drive uses a planetary gearbox with the motor mounted vertically at the top. Planetary gearboxes are often used on commercial wind turbines because they offer high reduction ratios from a…
Wind Turbine Yaw System: Mechanical Parts
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…
