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...

Abstract The locomotive traction motor is described as a rotor-bearing system coupling the kinetic equations of shaft and its support bearings with determination their elastic deformations in this study. Under effect excitations induced by dynamic rotor eccentric distance time-varying mesh stiffness, structure are formulated vibration environment locomotive. In addition, nonlinear contact force...

The article presents the basic principles of three-dimensional mathematical modeling operation a thrust plain bearing with fixed pads compressor. model is based on periodic thermoelastichydrodynamic (PTEHD) theory which allows calculating temperature at inlet to pad and considering complete thermal pattern. A description main provisions numerical implementation given. In stationary mode bearing...
