Generalized Equations for Roller One-Way Clutch Analysis and Design

In 1973, Sauzedde [1] wrote a paper that is commonly considered the benchmark document on roller One-Way Clutch (OWC) analysis and design. Among other topics, Sauzedde led the reader through analyses on contact stress, outer ring hoop stress, and roller centrifugal force computations. Following this seminal paper, several enhancements were presented, further refining the original equations [2] and better describing roller mechanics [3]. At the time these papers were written, the automotive industry in the U.S. predominantly used the English system of measure. The use of English units often obscured the original derivations of constants used in the equations. The purpose of this paper is to present the equations used in roller OWC analysis and design in terms of dimensionless units.
