With the objective of reducing windage power losses (WPL) in herringbone gears, WPL experiments involving the use of a shroud are conducted. Based on computational fluid dynamics (CFD), a herringbone gear numerical model is established. Based on the renormalization group (RNG) k–ε two-equation turbulence model and dynamic mesh technique, the features of flow field distribution around the gear; mechanism of reduction of WPL; shroud installation distance, coverage, and installation position; and influence law of WPL are analyzed. The CFD and experimental results, which exhibit good consistency, are used to infer the WPL behavior with respect to the input parameters.
