Disclosed is a mainframe for receiving a rotor-generator assembly of a gearless wind turbine, wherein the mainframe connects the rotor-generator assembly to the tower of the wind turbine; is rotatably mounted on the tower; and comprises pipe sections arranged at an angle to each other, one of which can be connected to the rotor-generator assembly and the other of which can be connected to the tower. The pipe section that can be connected to the rotor-generator assembly is connected to the lateral surface of the other pipe section by way of an end edge surface facing away from the rotor-generator assembly, and the lateral surface of the other pipe section extends into the region surrounded by the connection. |
