Transient elastohydrodynamic lubrication of gear line contacts.

Journal Article


Abstract


  • A rolling mill drive experiences excessive dynamic loads resulting from the torsional vibration of mass inertias and shafts with significant backlashes of gearing and coupling on the drive. As a result of these loads the mechanical parts of the drive, especially the gears, experience excessive pitting and spalling within a short time. This paper addresses the question as to whether the oil film thickness at the gear contacts is significantly reduced due to these dynamic loads. The dynamic loads are loads determined from the simulation of the drive in a nonlinear dynamic analysis where operating backlashes are fully modelled with realistic rolling practice. These dynamic loads are then considered in a transient elastohydrodynamic analysis of the gear line contact.
