Abstract
A drive system has a transmission unit with planetary gear stage and a first shaft associated with a planetary carrier and having a coupling flange connectable to a machine or rotor shaft. The transmission unit and a motor/generator unit includes a rotor connected with a rotation-lock to a hollow rotor shaft which is connected to a second shaft of the transmission unit and enclosed by a gearbox housing. A coupling is arranged radially between the second shaft and the hollow rotor shaft. A gearbox housing support with a hollow cylindrical extension is arranged between the transmission unit and the motor/generator unit. The cylindrical extension concentrically encloses an end section of the second shaft and forms a bearing seat for a bearing arrangement disposed radially between the second shaft and the cylindrical extension. The hollow cylindrical extension is concentrically enclosed by the rotor and the hollow rotor shaft.
