PLANETARY GEARBOX, DRIVE TRAIN, WIND TURBINE AND INDUSTRIAL APPLICATION

The invention relates to a planetary gearbox (10), which comprises at least three consecutively connected gearing stages (20, 30, 40). A first and a second gearing stage (20, 30) are designed as planetary stages (19). According to the invention, the third gearing stage (40) is designed as a planetary stage (19) having a stationary gearing component (11). Alternatively, the third gearing stage (40)is designed as a spur gear stage (21) and is coupled in turn to a fourth gearing stage (50), which is also designed as a spur gear stage (21). The invention further relates to a drive train (60) of awind turbine (70), in which wind turbine a corresponding planetary gearbox (10) is used as a gearbox (66). The invention further relates to a wind turbine (70) equipped with a corresponding drive train (60). Furthermore, the invention relates to an industrial application (80) having a corresponding planetary gearbox (10) as a gearbox (66). 本发明涉及一种行星传动装置(10)，其包括至少三个相继连接的传动级(20、30、40)。第一和第二传动级(20、30)在此被设计为行星级(19)。根据本发明，第三传动
