Abstract
A planetary transmission includes at least two planetary stages. A sun shaft of a planetary stage of the at least two planetary stages is connected for transmission of torque via a coupling toothing system to a planetary carrier of a second transmission stage of the at least two planetary stages that follows the first transmission stage. The coupling toothing system is a flat notch toothing system. A drive train of a wind power plant, in which a corresponding planetary transmission is used as transmission, is also provided. A wind power plant that is equipped with a corresponding drive train is provided. An industrial application that has a corresponding planetary transmission as transmission is also provided.
