System and method for developing fault diagnostics and failure prognosis of spline wear in a drive system

摘要

A diagnosis system and method to detect wear between a first set of teeth of a first gear and a second set of teeth of a second intermeshing gear, the diagnosis system having a first target associated with the first set of teeth, a second target associated with the second set of teeth, a first sensor adapted to detect the location of the first target, a second sensor adapted to detect the location of the second target, and a processing system in data communication with the first sensor and the second sensor, the processing system being adapted to process a spatial relationship between the first target relative to the second target after a time lapse of rotation between the first set of teeth and the second set of teeth.

1. A diagnosis system adapted to determine teeth wear between a first set of teeth of a first gear and a second set of teeth of a second intermeshing gear, the diagnosis system comprising:
a first target positioned on the first gear; a second target positioned on the first gear; a first sensor configured to detect a first rotational position of the first target as the first gear rotates; a second sensor configured to detect a second rotational position of the second target as the second gear rotates; and a processing system in data communication with the first sensor and the second sensor, the processing system being configured to process a rotational spatial relationship between the first rotational position and the second rotational position; wherein the first set of teeth intermesh with the second set of teeth; and wherein after a time lapse of rotation between the first set of teeth and the second set of teeth, the spatial relationship between the first target and the second target changes, thus indicating wear between the first set of teeth and the second set of teeth.
