Gearbox component and lubricant condition monitoring system
First Claim
1. A monitoring system for a gearbox having at least one rotational component with a design lifetime and a plurality of design parameters, the monitoring system comprising:
- a first sensor configured to generate a first signal indicative of a rotational speed associated with the at least one rotational component;
a second sensor configured to generate a second signal indicative of a torque associated with the rotational component; and
a controller electronically connected to the first and second sensors and configured to;
determine a remaining lifetime of the at least one rotational component based on the design lifetime, the plurality of design parameters, and the first and second signals over a period of operating time, wherein the plurality of design parameters includes a design torque and a design speed of the rotational component; and
generate a maintenance signal based on the remaining lifetime,wherein the maintenance signal is indicative of a need to perform gearbox maintenance before a threshold time period will elapse.

Abstract
A monitoring system for a gearbox having at least one rotational component having a design lifetime and at least one design parameter is disclosed. The monitoring system may include a first sensor configured to generate a first signal indicative of a speed associated with the at least one rotational component, a second sensor configured to generate a second signal indicative of a torque associated with the rotational component, and a controller electronically connected to the first and second sensors. The controller may be configured to determine a remaining lifetime of the at least one rotational component based on the design lifetime, the at least one design parameter, and the first and second signals over a period of operating time, and generate a maintenance signal based on the remaining lifetime.
