Abstract
A generator rotor shaft balancing system is disclosed. The generator rotor shaft balancing system includes a generator that includes a rotor and a rotor shaft. A weight is coupled to the rotor shaft. The weight is dynamically moveable, while the rotor is operating, to facilitate reducing vibrations in the rotor shaft.
Claims11
A generator rotor shaft balancing system comprising:
- a generator including a rotor and a rotor shaft;
- and
- a weight coupled to the rotor shaft;
- wherein the weight is dynamically moveable, while the rotor is operating, to facilitate reducing vibrations in the rotor shaft;
- and
- wherein the weight is configured to move eccentrically to different positions about a periphery of the rotor shaft.
3 more elements
A method of balancing a generator rotor shaft, the method comprising:
- coupling a moveable weight to a rotor shaft of a generator assembly;
- monitoring vibration within the rotor shaft while the generator assembly is operating;
- transmitting vibration data to a controller;
- and
- selectively causing, by the controller, to eccentrically move the weight relative to the rotor shaft to position the weight about a periphery of the rotor shaft, while the generator assembly is operating, to facilitate reducing the vibrations in the rotor shaft.
