An Experimental Investigation of Churning Power Losses of a Gearbox
Volume 10: 2017 ASME International Power Transmission and Gearing Conference, 2017 In this study, load-independent (spin) power losses of a gearbox operating under dip-lubrication conditions are investigated experimentally using a final-drive helical gear pair from an automotive transmission as the example system. A dedicated gearbox is developed to operate a single gear or a gear pair under given speed and temperature conditions.

Development of an analytical model to predict the churning power losses of an orthogonal face gear
Engineering Science and Technology, an International Journal, 2023 As one of the basic energy dissipations for one orthogonal face gear running partially submerged in an oil bath, there is no open literature concerned on the churning power losses of the face gear. This paper proposed a series of formulas to predict the churning losses for one orthogonal face gear running partially submerged in an oil bath.
