In this paper the experimental behavior of a cylindrical journal bearing working in critical conditions, namely at very low speed and high specific pressure, is described. A bearing with the nominal diameter of 160mm and the length of 145mm was used. The rotational speed was fixed at 60rpm (1Hz), while the applied load varied from 20kN to 350kN in the vertical direction, corresponding to the Sommerfeld number ranges from 0.1314 to 0.0086. Measurements of static position, hydrodynamic pressure, temperature profiles, and dynamic coefficients have been presented and discussed.

Abstract

In this paper the experimental behavior of a cylindrical journal bearing working in critical conditions, namely at very low speed and high specific pressure, is described. A bearing with the nominal diameter of 160mm and the length of 145mm was used. The rotational speed was fixed at 60rpm (1Hz), while the applied load varied from 20kN to 350kN in the vertical direction, corresponding to the Sommerfeld number ranges from 0.1314 to 0.0086. Measurements of static position, hydrodynamic pressure, temperature profiles, and dynamic coefficients have been presented and discussed.
