Definitions
- the invention relates to a transmission according to the preamble of claim 1.
- the invention has for its object to eliminate the inherent disadvantages of the prior art solutions disadvantages.
- torsional vibrations in transmissions with rotating shafts should be damped as effectively as possible.
- the transmission which may be about a wind turbine gearbox, has at least one actuator.
- An actuator is a means that influences a physical quantity as a function of a signal supplied to the actuator.
- a signal is a physical quantity in which one or more parameters carry information about one or more variable quantities. In the present case, it is preferably an electrical signal.
- the transmission is configured to transmit a torque flow from a driving device to a driven device. With transmission of the torque flow, the transmission of an input torque to which an input shaft of the transmission is applied is referred to intermediate waves to an output shaft of the transmission.
- the input shaft and the output shaft in the present case form coupling points for the driving device and the driven device.
- the driving device applies input torque to the input shaft.
- the output torque applied to the output shaft is transferred to the driven device.
- the driving device may be, for example, the rotor of a wind turbine, whose rotor blades are acted on by the wind with the input torque. Accordingly, the driven device may be a generator of the wind turbine.
- the actuator is different from both the driving device and the driven device. Neither the driving device nor the driven device is thus the actuator. Also, the actuator is neither part of the driving device nor part of the powered device. So there are three different devices: Actuator, driving device and driven device. This implies that the rotor has none of the coupling points for the driven or driving device.
- the actuator according to the invention comprises a rotor and a stator. It is not a linear actuator, but a rotating actuator.
- the rotor which is rotatably mounted, is rotatably mounted relative to the stator.
- the stator is arranged rotationally fixed.
- a voltage acting between the rotor and the stator is used. kendes torque.
- a direction vector of the torque and an axis of rotation of a shaft of the transmission are congruent, in particular run parallel.
- the rotor is rotatably connected to said shaft.
- the rotor may be a separate component.
- the shaft forms the rotor. This implies that the rotor and the shaft are integrally connected.
- the stator is about an eddy current in question, which acts on the shaft and induces eddy currents in the wave.
- the shaft As a shaft, with which the rotor is rotatably connected, every shaft of the transmission in question, as well as its intermediate shafts. In a preferred embodiment, however, the shaft is the output shaft.
- the actuator and the driven device are arranged at different, opposite ends of the output shaft.
- the shaft end, on which actuator is arranged, is opposite to the above-mentioned coupling point for the driven device.
- the rotor of the actuator is rotatably connected to the shaft end, or the shaft end forms the rotor.
- the shaft may be the input shaft.
- the actuator and the driving device are then arranged on different shafts of the input shaft.
- the rotor of the actuator is also rotatably connected to the shaft end, or the shaft end forms the rotor of the actuator.
- the actuator is at least partially, preferably completely, disposed within a transmission housing of the transmission.
- At least one sensor is provided in a preferred development. This is preferably designed to measure the vibrations of the shaft on which the torque of the actuator acts.
- the transmission is preferably part of an arrangement with at least one control unit.
- the sensor is connected signal-conducting, so that the control unit receives information about the measured vibrations.
- the control unit is designed to control the actuator so that the vibrations are eliminated or damped.
- Fig. 2 shows a transmission with sensor and a second actuator variant.
- the transmission 101 shown in FIG. 1 has an input-side planetary stage 103 and an output-side spur gear stage 105.
- To the spur gear 105 includes an output shaft 107.
- the output shaft can be rotatably connected to a rotor of a generator.
- a rotor-side end 1 1 1 of the output shaft 107 is the generator-side end 109 opposite.
- an actuator 1 13 arranged. A torque of the actuator 1 13 acts on the rotor-side end 1 1 1 of the output shaft 107th
- the aim is to eliminate torsional vibrations of the output shaft 107.
- the vibrations to be eliminated are detected by a sensor 15.
- a corresponding measurement signal 1 17 is passed to a control unit 1 19 and detected and processed by this.
- control unit 1 19 In dependence on the measurement signal 17, the control unit 1 19 generates a control signal 121, which is fed to the actuator 1 13 and controls it.
- the torque applied by the actuator 1 13 to the output shaft 107 is dependent on the actuating signal 121.
- the control unit 1 19 calculates the actuating signal 121 in such a way that the torque corresponds to a countervibration to the vibration measured by the sensor 15.
- FIG. 2 shows an actuator 201 which fulfills the same function as the actuator 1 13 shown in FIG. 1, but in contrast to the actuator 1 13 is arranged within a housing 203 of the transmission 101.
- the actuator 201 has no separate rotor.
- the output shaft 107 serves as a rotor.
- a stator of the actuator 201 exerts a torque directly on the output shaft 107. This can be realized, for example, by means of an eddy current brake serving as an actuator 201.
