CFD analysis on the oil flow of a gear stage with guide plate

Abstract Gearbox housing geometry and oil guide plates strongly influence gearbox flow interaction of with machine elements. Guided can increase efficiency improve heat management. Recent research studies have demonstrated the potential Computational Fluid Dynamics (CFD) simulations to predict no-load losses. Thereby, has rarely been addressed. This study focuses on a CFD analysis dip lubricated spur gear stage plate. Grid-based models different simulation setups were confronted evaluated. Results show that selection setup respect acceleration ramp mesh size needs address considered object investigation desired depth information. An appropriate shows great accordance recordings distribution by high-speed camera. A detailed results identified contribution surface zones loss torque. For plate strong torque due pressure forces tooth flank shear front tip circle gears was determined.
