Influence of lubricant type on churning power loss of worm gear [PDF]

Tribology and Materials
This 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.

Investigation of Drag and Churning Losses on Tapered Roller Bearings

Strojniški vestnik – Journal of Mechanical Engineering, 2015
Today there are a lot of findings to determine losses caused by contact forces inside roller bearings. But there are also losses in bearings caused by displacement of lubricant. These are known as churning or drag losses. In general the bearing manufacturers give recommendations how to reduce them.
