To limit the adverse effect of the fluid pressure field in high-speed gearing systems, especially for the main koip share price reducer of helicopters, shrouds usually adopted to enclose and approaches the high-speed gears will play a vital role in the windage and pumping power losses in axial and radial directions.To better explore and predict the total load-independent losses, this paper proposes an improved quasi-analytical method to quantify the power losses caused by the gel bottle audrey the windage and pumping effects, considering the gear pump characteristics with the compressibility of the air or air-oil mixture.The theoretical calculations using the improved model are then compared with experimental results in the open literature.

Leveraging the swept volume of the gear pump, the squeezing/pocketing behavior of the fluids in the tooth space can get a better understanding as the shroud approaches the gear pair.
