Abstract
A gear roll-testing method directed to the analysis and display of gear-set performance data, including motion transmission error, as acquired on gear-set rolling testers or gear-box test fixtures and includes the analysis and visualization of this data in the time-domain, frequency domain, and hybrids thereof. The invention further includes fundamental improvements in core signal processing, analytical and signal processing sequences that allow the data to be explored in more insightful ways, methods of visualizing and reporting the data and results, and a man-machine user-interface paradigm to provide these functions and features with greater flexibility and utility.
