 Predicted Effect of Dynamic Load on Pitting Fatigue Life for Low-Contact-Ratio Spur Gears by David G. Lewicki

Primary title page identifies David G. Lewicki and June 1986. The NTRS identifier starts with 1987 but the publication date is 1986. Summary, printed p. 1, and Summary of Results, printed p. 11, describe calculated dynamic tooth loads and predicted pitting-fatigue life for low-contact-ratio spur gears.

Summary and Introduction, printed p. 1 (PDF p. 3), specify the modified TELSGE tooth-stiffness model and stiffness–dynamic-load iteration; tooth stiffness and dynamic loads were calculated as functions of contact position and speed. These are model calculations, distinct from the 2009 endurance-monitoring experiment cited separately.
