摘要：
As the gear speed becomes higher and higher in modern industry the influence of spin flow on lubricating oil jet must be taken into account in design of gearings. A multiphase flow model is established in computational fluid dynamics (CFD) to calculate the regimes of oil jet in spin flow. Schemes are developed to eliminate the effect of oil jet deviation in into mesh lubrication. The contraflow in out of mesh condition is analyzed and found that the complete contra-flow arises when spray velocity is less than 1% (or higher for large module) of pitch velocity. The analysis results were verified by experimental results. (C) 2015 Elsevier Ltd. All rights reserved.
