ON THE EXISTENCE OF SOLUTIONS OF EQUILIBRIA IN LUBRICATED JOURNAL BEARINGS

In this paper we study a system of equations concerning equilibrium positions of journal bearings. The problem consists of two surfaces in relative motion separated by a small distance filled with a lubricant. The shape of the inlet surface is circular, while the other surface has a more general sha...

Zusammenfassung:	In this paper we study a system of equations concerning equilibrium positions of journal bearings. The problem consists of two surfaces in relative motion separated by a small distance filled with a lubricant. The shape of the inlet surface is circular, while the other surface has a more general shape. Our result shows the existence of at least one equilibrium by using degree theory.
