Description
  • This paper deals with the behavior of oil in the gear-box. For numerical simulations, the commercial software Fluent was used for relatively complicated problems of the two-phase unsteady turbulent flow. First of all, problems are focused on simplified models of one gear and set of gears, then finally on the model of complete gear-box. These cases are solved as unsteady problem - computation leads from start time, where oil pool is in calm, to the stable regime, where oil pool is in balance.The numerical study is consisted of several cases; run-up cogwhell or set of gears with the calm pool of oil, run-up with changes of oil pool sway, influence of viscosity changes on oil flows inside gear-box and run-up complete gear-box with calm pool of oil.

  • Článek se zabývá chováním oleje v převodových skříních. Pro numerickou simulaci je použit komerční software Fluent. Nejprve bylo sledováno proudění na modelu osamoceného kola a soukolí, a v konečné fázi bylo použito modelu kompletní převodové skříně. Proudění je řešeno jako nestacionální problém - výpočet vychází z počáteční fáze, kdy je olejová lázeň v klidu, do ustáleného stavu proudění, kde je olejová lázeň v rovnováze. (cs)
