Tribological properties of flexspline materials regulated by micro-metallographic structure

Tribology International, 2018
Abstract Flexspline wear is a critical factor leading to harmonic drive failure. This study investigates the tribological properties of five typical flexspline materials under dry friction conditions. A wear mechanism regulated by micro-metallographic structure is proposed.
