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 FluidsSpiral 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.
