Analytical and Experimental Study of Gear Surface Micropitting Due to Variable Loading [PDF]

Applied Mechanics and Materials, 2015
This paper presents an investigation of the effect of load variation on gear tooth surface micropitting, for an application in planet gears in a wind turbine gearbox. To study the effect of load variation, two methods are employed: an experimental testing of gear micropitting under variable loading and a probabilistic analysis of gear contact stress ...

The effect of contact severity on micropitting: Simulation and experiments

Tribology International, 2019
Abstract A numerical contact fatigue model combining the effects of rolling contact fatigue and wear has been developed based on mixed elastohydrodynamic lubrication (EHL) theory, continuum damage mechanics (CDM) and the Archard's wear law. A series of benchtop tests were conducted using a triple-contact test rig to study the influence of surface ...
