See full text

A member for axially fixing and/or tensioning a planetary bolt, in particular a planetary bolt of the planetary gear stage of the transmission of a wind turbine. Based on the idea of providing a screw joint for axially fixing and/or tensioning a planetary bolt in the immediate vicinity of a section of the planetary bolt which has a shoulder for the axial fixing and/or tensioning of planetary bearings. This enables short load paths between the planetary bearings and the screw joint and, consequently, high rigidity.
