Analytical Crack Propagation Scenario For Gear Teeth And Time-Varying Gear Mesh Stiffness

, 2012
In this paper an analytical crack propagation scenario is proposed which assumes that a crack propagates in the tooth root in both the crack depth direction and the tooth width direction, and which is more reasonable and realistic for non-uniform load distribution cases than the other presented scenarios.
