A lubrication system for a spline interface (20) includes at least one debris chamber (46) located radially outboard of the spline interface (20) of a first rotating component (16) and a second rotating component (18). Wear debris (44) is urged from the spline interface (20) toward the at least one debris chamber (46) by rotation of the first and second rotating components (16, 18) about a central axis (14). At least one lubricant reservoir (36) contains a volume of lubricant (40), wherein at least a portion of the volume of lubricant (40) flows toward the spline interface (20) in response to the wear debris (44) being urged from the spline interface (20) toward the at least one debris chamber (46).

A turboalternator system includes a turboalternator having a rotatable member operatively engaged to a bearing set, a radial support element, and a contact structure engaged with the radial support element. The rotatable member defines a first end, a second end and an axis of rotation. The turboalternator system is configured to be thermally adjustable such that in a first thermal condition the contact structure is at a first radial position with respect to the axis of rotation and contacts the rotatable member to provide support, and in a second thermal condition the contact structure is at a second radial position with respect to the axis of rotation that is spaced further from the axis of rotation than the first radial position.

A dynamoelectric machine comprises a first rotor shaft, a second rotor shaft and a central element. The first rotor shaft rotates about a central axis of the machine and has a first magnetic drive element disposed about an outer circumference of the first rotor shaft. The second rotor shaft rotates about the first rotor shaft and has a second magnetic drive element disposed about an inner circumference of the second rotor shaft. The central element is disposed between the first rotor shaft and the second rotor shaft and is configurable to remain stationary while the first rotor shaft and the second rotor shaft rotate about the central axis. The central element also includes a third magnetic drive element for interacting with the first magnetic drive element, and a fourth magnetic drive element for interacting with the second magnetic drive element.

An electrically powered driveline assembly includes a first electric motor and a second electric motor that drive corresponding input shafts to drive an output shaft. The first and second electric motors are selectively coupled to facilitate constant torque and speed output of the output shaft during shifting and also in the event of failure of one of the electric motors.

A constant speed ratio speed increaser friction wheel drive train for a wind turbine is disclosed. The drive train may include at least one drive wheel adapted to receive mechanical energy from a main shaft of a wind turbine and capable of rotating at an input rotational speed, the at least one drive wheel constructed of a plurality of drive wheel segments and at least one driven wheel in contact with and rotating against a surface of the at least one drive wheel at an output rotational speed, the output rotational speed varying with the input rotational speed.
摘要:
A cooling system for a sealed permanent magnet electric machine includes a fan element configured to urge an airflow across a plurality of permanent magnets of a rotor of the electric machine to remove thermal energy therefrom. A plurality of cooling channels are located in a housing of the electric machine and are configured to transfer thermal energy from a stator of the electric machine to a flow of liquid coolant through the plurality of cooling channels. A heat exchanger is located in thermal communication with the plurality of cooling channels to transfer thermal energy from the airflow to the liquid coolant. One or more coolant supply conduits are configured to divert a portion of the airflow from the heat exchanger to an ancillary component of the electric machine to allow for transfer of thermal energy from the ancillary component to the airflow.
