Abstract

The invention concerns a method of connecting two rotor blade segments (132, 134) of a wind turbine rotor blade (110), the method comprising the steps of: - providing a first rotor blade segment (132) and a second rotor blade segment (134), wherein a displaceable thread insert (172) is arranged within the second bushing (142), - inserting a connecting bolt (146) into the second bushing (142) and axially moving the displaceable thread insert (172) with the connecting bolt (146) into the first state, in which the displaceable thread insert (172) is locked against rotation relative to the corresponding second bushing (142), - screwing the connecting bolt (146) into the displaceable thread insert (172), - axially moving the displaceable thread insert (172) into the second state, in which the displaceable thread insert (172) is rotatable relative to the corresponding second bushing (142), - screwing the connecting bolt (146) into the first bushing (140), and - tightening the connecting bolt (146) to mechanically connect the two rotor blade segments (132, 134). The invention also relates to a bushing (142) and a wind turbine rotor blade (110).
