Abstract [en]

Evolution of friction torque in a pivoted-pad thrust pad bearing, as well as collar and shaft temperatures and pressure profiles in transient conditions, have been investigated in [1]. The present paper reports further transient test results for the same thrust bearing with an outer diameter of 228.6mm and 60% offset pivoted pads, operated in fully flooded mode. In this study, a complete set of bearing main performance parameters, including bearing pad and collar temperatures, oil film thickness and friction torque are obtained by means of a high-speed data acquisition system. Evolution of these parameters as a result of sudden variations in rotational speed and load are presented and analysed. Results are generalised in terms of Fourier number and compared with published numerical data.
