20.500.12556/RUL-146676 Experimental study and numerical analysis on windage power loss characteristics of aviation spiral bevel gear with oil injection lubrication Eksperimentalna študija in numerična analiza izgub moči zaradi ventiliranja pri letalskih stožčastih zobniških prenosnikih s spiralnimi zobmi, mazanih z vbrizgavanjem olja With the increasing speed of aviation spiral bevel gears, the load-independent windage power losses caused by hydrodynamic have increasingly more influence on gear transmission efficiency. Firstly, a test rig for the windage power loss of spiral bevel gear under oil-jet lubrication is established, and on this basis, a method for measuring windage torque is proposed. Next, the interactive effects of different injection lubrication parameters on the windage power loss were studied by orthogonal experiment, and the formula for calculating the windage loss was obtained by fitting the experimental data. Then, the fluid distribution, velocity field and pressure field around the gear were analysed by using a computational fluid dynamics (CFD) numerical model, and the mechanical and energy characteristics of the gear windage power loss were obtained. Finally, the dimensionless processing of the windage moment was carried out, and the variation of the dimensionless windage moment coefficient with the rotational Reynolds number is obtained. The comparison between the dimensionless windage moment coefficient of experimental data and simulation results shows that the CFD values are in good agreement with the measured data. This study provides experimental and methodological guidance for the calculation of windage power loss and windage reduction design of aviation gear pair under oil injection lubrication. spiral bevel gear oil-jet lubrication windage power loss windage test stožčasti zobniki mazanje z oljnim curkom izgube zaradi ventiliranja preizkus ventiliranja true false true Angleški jezik Slovenski jezik Članek v reviji 2023-06-06 11:11:43 2023-06-06 11:11:48 2023-06-15 11:19:41 0000-00-00 00:00:00 2023 0 0 Str. 235-247 no. 5/6 Vol. 69 May/Jun. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.62:621.8 0039-2480 10.5545/sv-jme.2023.558 154643203 Li,_Wang-Experimental_study_and_numerical_analysis_on_windage_power_loss_characteristics_of_aviation_spiral_bevel_gear_with_oil_injection_lubrication.pdf Li,_Wang-Experimental_study_and_numerical_analysis_on_windage_power_loss_characteristics_of_aviation_spiral_bevel_gear_with_oil_injection_lubrication.pdf 1 9A8A8132A2E8FD727B43773A1E304541 f3732eb3075d37570d30a2679818efe1fbf4932640e1c6914321724ad492c133 0cea237a-044a-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169917 https://www.sv-jme.eu/sl/article/experimental-study-and-numerical-analysis-on-windage-power-loss-characteristics-of-aviation-spiral-bevel-gear-with-oil-injection/ 1 e866ca4a-0449-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169916 Fakulteta za strojništvo Strojniški vestnik 0 0 0
