Aircraft Engine Driven Accessory Shaft Coupling Improvements Using High-Strength, Low Wear Polyimide Plastic.

Abstract

Splined shaft couplings which connect generators, pumps, starters, and other accessories to aircraft engines and gearboxes frequently exhibit high wear and failure rates. In an effort to improve aircraft safety, reliability, and readiness, the Naval Air Test Center has engaged in a continuing spline improvement program over the past 9 years. This Technical Memorandum describes the development and test of two unique spline coupling modifications which have proven to be essentially immune to wear and failure in the aircraft power transmission applications which have been evaluated. Specific design information and application concepts are discussed to introduce this new spline coupling technology to mechanical equipment designers. (Author)
