AN EVALUATION OF CONFORMAL CONTACT GEARS

Abstract

The report concludes the program for the evaluation of one form of the conformal gear geometry. The program comprised the design, fabrication, inspection, and load testing of one form of the conformal gear tooth geometry. The test gears were case-carburized and ground in accordance with high aircraft quality standards and the applicable specifications. Load capacity of this particular tooth form was determined by a programmed increase in load until failure was attained. Results of this test program indicated that the gear member was the weakest in bending strength, and that a better balance between contact stress and bending stress will be necessary in future designs.
