Abstract
A repair device is provided for a wind turbine having a bearing with damaged teeth driven by a motor. The repair device includes a carrier for connection to the bearing and radially aligned with the damaged teeth. A gear train is mounted on the carrier for creating a torque transfer path from the motor to non-damaged teeth of the bearing.
Claims19
A repair device for a wind turbine having a hub and a bearing with damaged teeth driven by a motor, comprising:
- a carrier plate for connection to the bearing and radially aligned with the damaged teeth;
- and
- a gear train mounted along the length of the carrier plate for creating a torque transfer path from the motor to non-damaged teeth of the bearing, wherein the carrier plate and the gear train are separate from the bearing and the hub and attached to the hub with fasteners.
A repair device for a wind turbine having a hub and a bearing with damaged teeth driven by an output gear of a motor, comprising:
- a carrier plate for connection to the bearing and radially aligned with the damaged teeth;
- and
- a gear train mounted along the length of the carrier plate and extending along a concave centerline, comprising:
- a drive gear configured to receive torque from the motor;
- a pair of idler gears positioned on opposite sides of the drive gear and configured to mesh with the drive gear;
- and
- a pair of pinion gears meshed with the respective idler gears and with non-damaged teeth of an inner ring of the bearing for delivering torque from the drive gear to the non-damaged teeth of the bearing, wherein the carrier plate and the gear train are separate from the bearing and the hub and attached to the hub with fasteners.
A method of installing a repair device on a wind turbine having a hub and a bearing with damaged teeth driven by an output gear of a motor, the method comprising:
- providing the repair device comprising a gear train mounted along the length of a carrier plate separate from the bearing and the hub;
- removing the output gear;
- radially aligning the repair device with the damaged teeth on the bearing;
- and
- connecting the separate carrier plate to the hub with fasteners such that the gear train is coupled to the motor and creates a torque transfer path from the motor to non-damaged teeth of the bearing.
