Abstract: 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. The rotor blade also includes one or more pin joints for connecting the first and second blade segments at the chord-wise joint. The pin joint(s) includes one or more pin joint tubes received within the pin joint slot(s). The pin joint slot(s) are secured within a bearing block. Further, a gap is defined between the pin joint slot(s) and the bearing block. Moreover, the rotor blade includes a shim within the gap between the pin joint slot(s) and the bearing block so as to retain the pin joint slot(s) within the bearing block. In addition, the shim is constructed of a liquid material that hardens after being poured into the gap.

Abstract: 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.
