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 ...
