An engine system includes a gearbox assembly that includes a housing having plural interconnected gears disposed between an engine side of the housing and an alternator side of the housing, a rotatable engine coupler connected with the engine side of the housing, the engine coupler configured to engage a rotatable shaft of an engine, and a rotatable alternator coupler connected with the alternator side of the housing, the alternator coupler configured to engage a rotor of a first alternator. The housing is configured to be positioned between the engine and the first alternator. The engine coupler is configured to engage the engine that is resiliently mounted in the powered system and the alternator coupler is configured to engage the first alternator that is rigidly mounted in the powered system to transfer rotation of the shaft of the engine to rotation of the rotor of the first alternator.

Gearbox assembly

A system and method are provided to monitor the health of a wind turbine gearbox. The system includes a plurality of sensors coupled to the wind turbine gearbox and a controller coupled to the plurality of sensors. The controller is configured to acquire vibration information from a vibration sensor, acquire a tachometer signal, convert the tachometer signal and the vibration information into a cycle domain signal, and perform an order analysis on the cycle domain signal, the order analysis providing information that identifies potential and actual damage within the wind turbine gearbox.
