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 at least one design parameter, the monitoring system comprising:
- 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 and 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.

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.

20. A monitoring system for a gearbox having at least one rotational component having a design lifetime and at least one design parameter, the monitoring system comprising:
-
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; a third sensor configured to generate a third signal indicative of a vertical load on the at least one rotational component; and a controller electronically connected to the first, second, and third sensors and 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, second, and third signals over a period of operating time, wherein the at least one design parameter includes one or more of a design torque, a design speed, and a design load; 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.
