Bushing for a wind turbine rotor blade, flange insert, wind turbine rotor blade and wind turbine

Abstract

Bushing for a wind turbine rotor blade, flange insert, wind turbine rotor blade and wind turbine The invention relates to a bushing (116) for a wind turbine rotor blade (104), the bushing (116) comprising a first bushing end (117) and an opposite second bushing end (118); a bushing bore (119) which extends in a region between the first bushing end (117) and the second bushing end (118) and comprises a bore longitudinal axis (120); wherein, along the bore longitudinal axis (120) in the direction of the second bushing end (118), the bushing bore (119) comprises a threaded portion (127), and wherein the bushing (116) comprises a bushing runout (128) that follows the threaded portion (127), said bushing runout comprising a widening portion (131) of the bushing bore (119), in which a diameter (132) of the bushing bore (119) enlarges at least monotonically while an increase in diameter decreases at least monotonically. The invention also relates to a flange insert (113), a wind turbine rotor blade (104) and a wind turbine (100).
