Materials Selection for Spur Gears by Using CMS Software

摘要

Materials selection for light, strong, durable spur gears is developed for preliminary spur-gear designs by using Cambridge Materials Selector (CMS) Version 2.01. Spur-gear models are developed from bending fatigue stresses and surface fatigue stresses based on Lewis and Hertz works. A coupling equation of bending fatigue stresses and surface fatigue stresses is determined for optimum materials selection. CMS generates the graphical material database to select the best materials based on a coupling equation.
