Abstract: A drive system for a wind turbine includes a transmission unit with a planet wheel stage. A coupling flange on a first shaft of the transmission unit can be connected to a driven machine shaft or rotor shaft which is mounted above a planet carrier. The transmission unit and a motor/generator unit connected with a second shaft of the transmission unit are enclosed by a gear case. A rotor of the motor/generator unit is connected to a hollow rotor shaft which surrounds an end section of the second shaft and is connected to the end section via an interior coupling or clamping connection. A connecting-piece is arranged between the transmission unit and the motor/generator unit, and concentrically surrounds a transmission-side end section of the rotor shaft, forming a bearing seat for the rotor shaft, which also supports the second shaft of the transmission unit.

Abstract: A drive system has a transmission unit comprising at least one planet wheel stage, which has a hollow wheel, several planet wheels, a planet carrier and a sun wheel. Furthermore, a first shaft associated with the transmission unit is provided, which has a coupling flange that can be connected to a work machine shaft or rotor shaft and is mounted via the planet carrier. The transmission unit and a motor unit or generator unit connected to a second shaft of the transmission unit are enclosed by a gear housing which has a cardanic circumferentially symmetric or partially symmetric suspension for connection to a supporting structural element of the wind turbine.

Abstract: Torque can be detected in a transmission by using at least one vibration sensor to detect at least one vibration signal which is associated with a tooth engagement frequency of intermeshing transmission toothings, and the phase shift of which is dependent on at least one tooth engagement duration of the intermeshing transmission toothings. The tooth engagement duration is torque-dependent as a result of toothing deformations. A torque acting on the transmission is determined from the phase shift of the detected vibration signal and/or of the at least one tooth engagement duration.

A slide bearing material of a first bearing element of the axial slide bearings is applied between a planetary carrier cheek and an end side of a planetary gear. The end side of the planetary gear or the planetary carrier cheek forms a corresponding cooperating second bearing element.

Abstract: A method for identifying possible damage in a toothed transmission stage having at least one pair of engagement toothed wheels includes measuring with a vibration transducer an oscillation signal corresponding to oscillations produced by a rolling and impact motion when teeth of a pair of the toothed wheels mesh under load during operation of the transmission stage, comparing the oscillation signal with a calibration oscillation signal, determining a torque acting on the transmission stage from a difference between the oscillation signal and the calibration oscillation signal, and evaluating the measured oscillation signal commensurate with the determined torque to identify the possible damage to the transmission stage.
