Numerical Visualization of Grease Flow in a Gearbox
Chinese Journal of Mechanical Engineering, 2023 Lubricating greases are widely used in e.g. open gear drives and gearboxes with difficult sealing conditions. The efficiency and heat balance of grease-lubricated gearboxes depend strongly on the lubrication mechanisms channeling and circulating, for ...
