Abstract

A main bearing unit for supporting the rotor shaft of a wind turbine, including a rolling bearing having an inner ring, an outer ring and a rolling element arrangement received between the outer and inner ring and a coupling arrangement which is designed to couple the rotor shaft to an output shaft of the wind turbine at least indirectly and so as to transmit torque. The rotor shaft is coupled to one of the outer and inner ring so as to transmit torque. The coupling arrangement is coupled so as to transmit torque to the one of the outer and inner ring as the rotor shaft.
