Evaluation of the Effect of Gear Tooth Grinding Methods on Fatigue Life of Spur Gears

摘要

The objective of the gear testing program was to provide growth potential for high capacity transmission systems, such as the CH-47A. Increased load carrying capacity for a gear system may be related to improvements in design, materials, or processing, or operating environment. This program undertook to compare three significantly different gear tooth grinding methods, and assess their effect on bending fatigue life. The three methods evaluated are as follows: (1) 'Maag' (Maag Gear-Wheel Co., Zurich, Switzerland); (2) 'Reishauer' (Fellows Gear Shaper Co., Springfield, Vermont); (3) 'Form' (Gear Grinding Division, Michigan Tool Co., Detroit, Mich.).
