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.

Development of a gearbox test rig to evaluate the impact of oil formulations on churning and friction losses

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology
From large industrial to small high-speed transmission for electric vehicles, there is a growing interest in reducing the power losses on gearboxes. Hydrodynamic losses are especially relevant on high-speed gearboxes. On electric cars, the gearbox lubricant also works as a cooling fluid for the motor, which brings new challenges as performance under an
