More Information
Summary: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 load bearing block. Further, a gap is defined between the pin joint slot(s) and the load bearing block. Moreover, the rotor blade includes a shim within the gap between the pin joint slot(s) and the load bearing block so as to retain the pin joint slot(s) within the load bearing block. In addition, the shim is constructed of a liquid material that hardens after being poured into the gap.
