Innovative Analysis and Documentation of Gear Test Results

The article "Innovative Analysis and Documentation of Gear Test Results" appeared in the September/October 2008 issue of Gear Technology.

Summary
In this paper, a method is presented for analyzing and documenting the pitting failure of spur and helical gears through digital photography and automatic computerized evaluation of the damaged tooth fl ank surface. The authors have developed an accurate, cost-effective testing procedure that provides an alternative to vibration analysis or oil debris methods commonly used in conjunction with similar test-rig programs.
