Wind turbine rotor blade, mounting sleeve and method for connecting two rotor blade segments

A mounting sleeve for a wind turbine rotor blade including a first rotor blade segment having a first connection end and a second rotor blade segment having a second connection end assigned to the first connection end, the first rotor blade segment having a first mounting sleeve at the first connection end, the first mounting sleeve having a first internal thread;

• the mounting sleeve comprising:
• a mounting sleeve body defining a longitudinal axis and having an internal thread arranged therein;
• said internal thread being displaceable axially with respect to the longitudinal axis;
• and,
• wherein the wind turbine rotor blade includes a connecting bolt configured to threadably engage the first mounting sleeve and the mounting sleeve via the first internal thread and said internal thread such that the first rotor blade segment and the second rotor blade segment are mechanically interconnected at the first connection end and the second connection end;
• and,
• an axially displaceable threaded insert which includes said internal thread.

A method for connecting a first rotor blade segment of a wind turbine rotor blade to a second rotor blade segment of the rotor blade, wherein

• the first rotor blade segment has a first connection end and the second rotor blade segment has a second connection end assigned to the first connection end, the first rotor blade segment has at the first connection end a plurality of first mounting sleeves which each have a first internal thread, and the second rotor blade segment has, at the second connection end, a plurality of second mounting sleeves which each have a second internal thread, wherein each of the plurality of second internal threads is displaceable axially with respect to a longitudinal axis of the corresponding second mounting sleeve,
• the method comprising:
• partially screwing connecting bolts into the second internal threads of the second connecting end such that each of the connecting bolts projects by a predetermined length from the second connection end;
• bringing the first connection end of the first rotor blade segment to the second connection end of the second rotor blade segment;
• partially screwing the connecting bolts into corresponding ones of the first internal threads of the first connection end;
• pushing together the two rotor blade segments;
• and,
• tightly screwing each of the connecting bolts such that a predetermined distance is achieved between a reference point defined on the connecting bolt and one of the first connection end and the second connection end.
