Description
  • The presented paper is focused on the static stiffness definition of fluid layer according to the number of Taylor vortices. There is a gap between two cylinders, where the inner one is rotating and axial flow is not assumed. The stiffness matrix as a function of angular speed is determined too. The fluid layer stiffness is specified for rotor in static balance and problem of damping is not considered. The Taylor vortices' influence is evident in the stiffness matrix, where all the elements are of the same orders of magnitude. In comparison with the stiffness matrix derived from the Reynolds equations, which has contrary the major diagonal elements lower by several orders of magnitude then the others, there is a marked difference. This theory will be used in new design of classical journal bearing using Taylor vortices principle.

  • Článek je zaměřen na definici statické tuhosti kapalinové vrstvy vzhledem k počtu Taylorových vírů. Máme dva válce, mezi nimiž je úzká mezera. Vnitřní válec rotuje a nepředpokládá se axiální proudění. Je dána matice tuhosti jako funkce úhlové rychlosti. Tuhost kapalinové vrstvy je dána pro rotor ve statické rovnováze bez tlumení. Vliv Taylorových vírů je zřejmý v matici tuhosti, kde se projeví shodnou velikostí diagonálních i mimodiagonálních prvků. Ve srovnání s řešením za pomoci Reynoldsových rovnic, kde jsou prvky na hlavní diagonále výrazně menší než na vedlejší, je zcela zřejmý rozdíl. Odvozená teorie bude použita pro nové řešení návrhu klasických kluzných ložisek. (cs)
