Abstract Purpose Thrust bearings play a critical role in high-speed rotating machinery, such as turbines, pumps, compressors, and turbogenerators, by transferring axial loads between the collar bearing pads. The lubricating fluid prevents contact, friction, wear solid parts acts cooling medium. purpose of this study is to evaluate first- second-order coefficients an inclined pad hydrodynamic th...

In this paper, a thermo-hydrodynamic model of the bump foil thrust gas bearing is developed, which solves coupled film three-dimensional energy equation, non-isothermal Reynolds and deformation equation. The effects speed, load, external cooling on temperature field are calculated analyzed. test rig was built to measure under different working conditions. Both simulation experiment results show...

The research used the thrust bearing of a 1298cc automobile. thrust-bearing material was annealed stainless steel (SS 201) with tensile strength 685 MPa and yield 292 MPa. objective to obtain best static analysis results based on CAE software analysis. method included design stages, parameters, fixed geometry determination, loading, meshing settings, computation, result data. simulation were in...

A thermoelastohydrodynamic (TEHD) coupling model is developed to study the static performance of a heavy-duty tilting pad thrust bearing (TPTB) under effect axis misalignment. To ensure validity in calculating thermoelastic deformation, calculation accuracy mechanical and thermal deformations used TEHD verified by finite element method (FEM). The influence on flow state prediction determined us...
