Research on windage power loss of spur gear base on CFD
The paper established three-dimensional Computational fluid dynamic (CFD) model of the oil-air mixture in the gearbox after meshing by ICEM CFD simulated the turbulence model by the CFD.The method of calculate the windage power loss (WPL) of the spur gear were put forward.In order to reduced the WPL,compared the results between the CFD model with different modulus,clearance of the shroud and radius of the modification of gear top.The result shows modulus is major parameter to WPL; the gear with shroud have lower WPL,WPL of the tooth flank and clearance of the tooth flank shroud do not show the proportional relationship,the gear with smallest clearance of gear side have lowest WPL,the modification of gear top can reduce the eddy scale which can reduce the WPL.
