Paper Abstract

In support of the gear mesh diagnostics research conducted at NASA Lewis Research Center a new high speed digital video imaging system has been developed to capture images of individual teeth on two meshing planetary gears rotating at high speeds. Each gear tooth image documents the progression of tooth wear, gear pitting, and tooth fractures that lead to overall gear failure. Previous imaging techniques used to document gear failure were restricted to post test analysis and did not allow a real time study of the degradation which leads to total gear failure. This imaging system is integrated with existing vibration detection hardware and operates autonomously to capture images of each gear tooth at predetermined vibration thresholds. Analysis of the data will allow researchers to define specific events in a failure process which lead to a better understanding of the causal factors of gear failure.
