Experimental Investigation on Churning Power Loss of Splash Lubricated Worm Gear [PDF]
Periodica Polytechnica Mechanical Engineering, 2023 Churning power losses are a complex phenomenon that produces critical power losses when considering the splash lubrication of gear units. This article describes the method to investigate the churning power loss in a worm gearbox. A particular test rig was designed and fabricated to experiment on single start worm gear incompletely submerged in an oil ...

Journal of Tribology, 2020 Abstract Oil sump lubrication is commonly used in gearboxes. When considering consistent speeds, oil immersion is usually set to low level in order to reduce associated power losses. This configuration is already used in some parts of helicopter mechanical transmissions, and it is under consideration as a lubrication solution for future ...

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. This study will solely look at how churning power losses are affected by mineral and synthetic oil on a test worm gear pair where the ...
