Influence of Aerated Lubricants on Gear Churning Losses–An Engineering Model

Tribology Transactions, 2011
It is currently assumed that churning losses can be described by using only two physical parameters representative of the lubricant properties, i.e., density and viscosity. To verify this hypothesis, a number of transient measurements were carried out on a specific gear test rig over a range of oil temperatures.

Churning power losses of a gearbox with spiral bevel geared transmission

Tribology International, 2019
Abstract To predict the churning power losses in a gearbox with spiral bevel geared transmission, based on the Computational Fluid Dynamics (CFD) method, a numerical simulation model for the splash lubrication of the intermediate gearbox of a helicopter including gear box housing, a spiral bevel gear pair and an oil guide device is established and ...

A study of churning losses in dip-lubricated spur gears

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 1999
Churning losses contribute significantly, both to overall inefficiency and to oil heating, in many dip-lubricated transmission systems, notably in automotive applications. For this reason, a reasonably accurate estimate of churning loss is often desirable at the design stage.

Oil distribution and churning losses of gearboxes: Experimental and numerical analysis

Tribology International, 2020
Abstract Currently, energy efficiency represents one of the main requisites in mechanical design. Gearboxes play an important role in several industrial applications and, even if they are already characterized by high efficiency, their performance can still be improved, leading to energy saving and the reduction of pollutant emissions.

A Note on Flow Regimes and Churning Loss Modelling

Volume 8: 11th International Power Transmission and Gearing Conference; 13th International Conference on Advanced Vehicle and Tire Technologies, 2011
The purpose of this study is to investigate the various fluid flow regimes generated by a pinion running partly immersed in an oil bath and the corresponding churning power losses. In a series of papers, the authors have established several loss formulae whose validity depends on two different flow regimes characterized via a critical Reynolds number ...

Housing Influence on Churning Losses in Geared Transmissions

Volume 7: 10th International Power Transmission and Gearing Conference, 2007
In a previous paper, a series of analytical formulas were presented enabling accurate predictions of churning losses for one gear which is typical of automotive transmission geometry. However, this formulation does not take into account the influence of flanges and deflectors.

Simulation of Churning Losses in Geared Box

Applied Mechanics and Materials, 2014
Relative experiments show that churning causes dominant power losses in geared box, which has an important influence on dynamic efficiency assessment of the driving system. This paper put forward a simulation model of churning losses and compared the simulation results with theoretical value.
