Experimental Investigation on Churning Power Loss of Splash Lubricated Worm Gear

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 ...

Transient Simulation Analysis of Needle Roller Bearing in Oil Jet Lubrication and Planetary Gearbox Lubrication Conditions Based on Computational Fluid Dynamics

Lubricants
The transient lubrication conditions of rolling bearings are different in gearboxes and bearing testers. It has been observed that samples of qualified rolling bearings tested in rolling bearing testers often fail and do not meet lifespan requirements ...

Epoxy–glass fibre composite splash ring suppresses metal-derived lubricant contamination in splash lubrication systems

Materials Advances
An epoxy–glass fibre composite splash ring suppresses metal-catalysed lubricant degradation at its source: Cu and Zn remain below 0.1 ppm, TAN is reduced by 85%, and oil flow increases by 66% compared with a conventional brass ring over 1000 h.

Experimental investigations and analysis on churning losses of splash lubricated spiral bevel gears [PDF]

Mechanics & Industry, 2017
Churning losses are a complex phenomenon which generates significant power losses when considering splash lubrication of gear units. However, only few works deal with bevel gears dipped lubrication losses. The objective of this study is to provide a wide variety of experimental tests on churning losses, especially getting interested in geometry of ...

Influence of the Lubricant Temperature of Splashed Lubricated Worm Gearbox on Churning Power Losses

ITEGAM- Journal of Engineering and Technology for Industrial Applications (ITEGAM-JETIA
The primary goal of lubricating a worm gearbox is to encourage sliding between teeth, which lowers the coefficient of friction and regulates the temperature rise brought on by rolling and sliding friction. Due to both non-load-dependent and load-dependent power losses, the worm gearbox has a relatively poor efficiency.
