Three-Dimensional Thermoelastohydrodynamic Analysis of Pivoted Pad Thrust Bearings Part 1: Treatment of Bearing Deflections and Fluid Film Flow and Heat Transfer

Abstract

A computational method is described for predicting the performance of pivoted pad thrust bearings. The model used allows for heat generation and transfa in the oil firm and also heat conduction in the pad and other solid parts of the bearing. Pad dejections due to both temperature variations and oil film pressures are calculated, and an overall solution procedure developed which allows all of these effects to interact.

Thermal Elastohydrodynamic Lubrication Analysis of Tilting Pad Thrust Bearings

“…Kim et al [8] analysed the effects of pivot position, inlet temperature, and ambient temperature on the temperature distribution on the pad surface. El-Saie and Fenner [9] calculated the effects of deflections due to both temperature and oil film pressure on TEHD of pivoted pad thrust bearings, and they [10] compared their computed results with experimental data, and generally good agreement is obtained for both temperature of pad surface and film thickness. Ettles and Anderson [11] examined the effects of load and disk support size on film thickness and pad face temperature, and they considered that 3D analysis of thrust bearing offers better accuracy and realism than 2D solutions.…”
