Impact of grease churning on grease leakage, oil bleeding and grease rheology
Tribology International, 2022 Grease performance is strongly determined by the properties and quantity of the grease after the churning phase in which grease reservoirs are formed. During this churning phase, macroscopic flow takes place, leading to drag forces dissipating energy in the grease, generating heat and causing thermo-mechanical degradation. The impact of grease churning

Observation of Grease Fluidity in a Ball Bearing Using Neutron Imaging Technology
Tribology Online, 2021 The grease fluidity and migration inside a ball bearing has been visualized non-destructively by using a neutron imaging technology. It has been clarified that a lithium (Li) complex grease with lower torque lubricates in the channeling state and that a ...

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 ...
