New Guideline for Determining the Reliability of Planetary/Spur Gear Units

In the wind power industry, the reliability of powertrain components plays a major role. Especially in multi-megawatt offshore applications, an unplanned replacement of drivetrain components can lead to extremely high costs. Hence, the expectation of wind farm operators is to forecast the system reliability. Under the leadership of the VDMA (Mechanical Engineering Industry Association), the standardization paper 23904 "Reliability Assessment for Wind Turbines" was published in October 2019.
