Parametric Study on the Roller Gear Reduction Drive

摘要

This report covers the parametric study of the roller gear drive to determine its applicability to current or projected Army helicopters. The basic principles used in the roller gear drive are presented. The results of a study to determine the weight, volume, and outside diameter as a function of ratio (from 20:1 to 100:1) and horsepower (from 250 to 4,000) are included. Other features, such as reliability, efficiency, life, vibrations, and cost are discussed.
