Influence of the Lubricant Temperature of Splashed Lubricated Worm Gearbox on Churning Power Losses [PDF]
ITEGAM-JETIAThe 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-
