Rotor for a wind turbine, rotor blade for a wind turbine, sleeve, and method for assembling a rotor

A rotor blade for a wind power installation, the rotor blade comprising:

• a rotor blade body extending from a blade root to a blade tip in a longitudinal direction having a longitudinal axis, wherein the blade root is configured to fasten the rotor blade to a rotor hub, wherein the rotor blade body includes a rotor blade inner part which comprises the blade root and a rotor blade outer part which comprises the blade tip, wherein the rotor blade inner part and the rotor blade outer part are connected to one another in a connecting region, wherein the connecting region includes:
• a transverse bolt recess in the rotor blade inner part extending substantially radially with respect to the longitudinal axis of the rotor blade, a transverse bolt arranged in the transverse bolt recess, wherein the transverse bolt has a transverse bolt opening that extends radially with respect to a longitudinal axis of the transverse bolt;
• a longitudinal bolt recess which extends substantially parallel to the longitudinal axis of the rotor blade and which extends at a first end of the rotor blade outer part to a second end at the transverse bolt recess, wherein the longitudinal bolt recess, the transverse bolt recess, and the transverse bolt opening form a common passage;
• and
• a sleeve arranged in the longitudinal bolt recess, wherein a longitudinal bolt extends through a cavity of the sleeve, and a section of the longitudinal bolt is arranged within the transverse bolt opening,
• wherein the sleeve extends from a first sleeve end to a second sleeve end, wherein the sleeve includes a first sleeve section at the first sleeve end having a first outer diameter, and includes a second sleeve section at the second sleeve end having a second outer diameter, wherein the second outer diameter is different from the first outer diameter.

A method comprising:

• coupling a first rotor blade part to a second rotor blade part by:
• arranging a transverse bolt within a transverse bolt recess of at least one of:
• the first rotor blade part or the second rotor blade part, wherein the transverse bolt recess extends substantially radially with respect to a longitudinal axis of the rotor blade;
• arranging a sleeve within a longitudinal bolt recess in at least one of:
• the first rotor blade part or the second rotor blade part, the sleeve including a cavity, wherein the longitudinal bolt recess extends substantially parallel to the longitudinal axis of the rotor blade wherein the sleeve extends from a first sleeve end to a second sleeve end, wherein the sleeve includes a first sleeve section at the first sleeve end having a first outer diameter, and includes a second sleeve section at the second sleeve end having a second outer diameter, wherein the second outer diameter is different from the first outer diameter;
• and
• arranging a longitudinal bolt within a common passage formed by the longitudinal bolt recess, the cavity of the sleeve, and the transverse bolt recess.
