Investigation of the Conformal Gear for Helicopter Power Transmission

摘要

This report covers Phase I of a study of conformal contact gearing to determine its applicability to current or projected Army aircraft. The work includes: (1) An analytical investigation of the conformal tooth bending and contact stresses; and (2) A design investigation, using the analytical method to illustrate the advantages and problems of the conformal tooth transmission for various ratios and horsepower inputs. Some results of an independent photoelastic stress investigation conducted by Vertol are also included. (Author)
