Windage, churning and pocketing power losses of gears: different modeling approaches for different goals

Forschung im Ingenieurwesen, 2016
Energy efficiency represents one of the most relevant trends in many fields, including the sector of power transmissions and gears, which are involved whenever power has to transmitted and transformed. For instance, in the automotive industry, gearboxes can contribute to the overall efficiency of the system and promote lower fuel consumption and ...

Numerical modelling of oil distribution and churning gear power losses of gearboxes by smoothed particle hydrodynamics

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2018
Sufficient oil supply of all machine elements in gearboxes is usually required to avoid damage during operation. Quite frequently, transmissions are conservatively designed with an oversupply of oil to guarantee operational reliability. An oversupply of oil results in an unnecessarily high amount of oil being kept in motion, which in turn leads to ...

Modeling of oil churning power loss in spiral bevel gears under oil injection lubrication

Physics of Fluids
Spiral bevel gears are widely used in automobile transmission systems, and their performance plays a crucial role in driveline safety and transmission efficiency. However, studies on the lubrication performance and churning power loss of spiral bevel gears under an injection lubrication system are still insufficient.
