Hydrodynamically lubricated contact between axial rings of the pinion and the wheel of a high-speed gearbox: Contribution to numerical assessment
Popis výsledku v původním jazyce
In this study, the hydrodynamically lubricated contact between axial rings of high-speed gearboxes considering their steady state operating mode is studied. Perfect geometry of rings and isothermal oil condition are next simplifying assumptions. The assumption that the contact of rings is hydrodynamically lubricated is suitable as the ratio between the minimal oil film thickness, hmin, and roughness, σ, fulfils the precondition hmin/σ >> 3 for the operating mode. The general Reynolds equation for 2D situation is then convenient to use for the determination of the oil pressure field and of the oil flow rate. Results for an example with a geometry of rings and with an operating mode are presented. Important dependence between the nominal film thickness and the value of transmitted axial force is brought out here for the considered lubricated contact. An attention is also devoted to friction losses.
