1. A system for monitoring a component coupled to a gear train in a shaft-driven gearbox, the system comprising:
a vibration sensor mechanically linked to the shaft-driven gearbox, the vibration sensor being located remotely from the component;
a speed sensor; and
a control unit having at least one processor and at least one non-transitory memory device, the at least one non-transitory memory device storing instructions that when executed by the at least one processor causes the at least one processor to perform operations, the at least one processor configured to:
collect speed data for the gear train, the speed data being acquired by the speed sensor;
collect vibration data acquired by the vibration sensor;
process the vibration data to extract a characteristic of the component by scaling the vibration data based on a gear ratio of the component to a shaft;
trend the characteristic of the component and the speed data; and
detect at least one response associated with the component based at least in part on the trends in the characteristic of the component and the speed data.
