Development of an Oil Free Water-Based Lubricant for Gear Applications
Lubricants, 2019 The aim of the current research is to develop a gear transmission fluid based on water and plant extract. Up to now, mineral or synthetic oils are used as lubricants in most gear drive applications. These oils are made of fossil raw materials and are non-

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 ...
