Abstract

This study presents a bending strength design for an external pinwheel gear set (e-PGS) pinion by incorporating an elastohydrodynamic lubrication-based friction coefficient formula for gear tooth surfaces. First, variations in the coefficient of friction are investigated under various design parameters, operating conditions, tooth surface roughness, and gear oil viscosity conditions. The contact force considering friction is then numerically determined, and the bending strength design is conducted based on the calculated contact force. Finally, the tooth root bending stress does not show significant changes with or without friction. We can conclude that friction can be neglected only in an e-PGS strength design.


Keywords: e-PGS(external pinwheel gear set), Slide-to-roll ratio, Coefficient of friction, Transmitted tangential force, Tooth root bending stress
