Influence of lubricant type on churning power loss of worm gear [PDF]
Tribology and MaterialsThis paper presents the results of experimental tests of the churning power loss of a single-stage worm gear. The churning power loss is a load-independent loss that occurs when the gear churns through the lubricant.

High Pressure Rheology of Lubricants (Part 2)
Tribology OnlineIn elastohydrodynamic lubrication (EHL) theory published in 1962, Dowson et al. derived a density pressure relational equation. Therefore, it seemed that this equation could be utilized as an estimation equation of the density term of the viscosity ...

Capillary Balancing: Designing Frost-Resistant Lubricant-Infused Surfaces
Nano letters (Print), 2020 Slippery lubricant-infused surfaces (SLIPS) have shown great promise for anti-frosting and anti-icing. However, small length scales associated with frost dendrites exert immense capillary suction pressure on the lubricant.
