Abstract:

An analysis is presented of the capacity of the cycloidal cam transmissions to provide Army aviation with a lightweight, high-reduction system design. The upper power transmission limitations of the concept are analyzed relative to efficiency, fatigue life, reliability and other factors. The treatment is limited to reduction ratio aspects, in the range from 181 through horsepower, and the speed range covers 4760 to 30,000 rpm. Special emphasis was given to the 280 to 2520 horsepower and 191-1501 reduction ratio sections to study compatibility with present-day gas turbine engines.
