摘要： A rotor blade for a wind turbine includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the first and second blade segments includes at least one shell member defining an airfoil surface and an internal support structure. The first blade segment includes a beam structure extending lengthwise that structurally connects with the second blade segment via a receiving section. The rotor blade also includes at least one chord-wise extending pin positioned through the chord-wise joint so as to secure the first and second blade segments together. Further, the chord-wise extending pin includes a hollow cross-section that extends from a trailing edge end to a leading edge end thereof.

摘要： A method for preventing a pitch bearing failure of a pitch system of a wind turbine includes monitoring, via at least one sensor, one or more electrical signals of a pitch motor of a pitch drive mechanism of the pitch system that drives a pitch bearing of the pitch system. The method also includes analyzing, via the controller, the one or more electrical signals of the pitch motor so as to remove noise and amplify outliers. Moreover, the method includes estimating bearing friction of the pitch bearing using the analyzed one or more electrical signals of the pitch motor. As such, the method includes implementing, via the controller, a control action when the estimated bearing friction of the pitch bearing indicates an anomaly in the pitch bearing.

摘要： A rotor blade includes first and second blade segments extending in opposite directions from a chord-wise joint. The first blade segment includes a beam structure that connects with the second blade segment via a receiving section. A chord-wise gap exists between an edge of the beam structure and an edge of the receiving section. The beam structure defines a first pin joint slot, whereas the receiving section defines a second pin joint slot that aligns with the first pin joint slot. First and second bushings are arranged in first ends of the first and second pin joint slots, each having a flange extending within the chord-wise gap. As such, the flanges abut against each other within the chord-wise gap so as to fill the chord-wise gap with a predetermined defined gap or interference. Further, a chord-wise extending pin is positioned through the bushings so as to secure the first and second blade segments together.
