Methodology for the Control of Wear of Journal Bearing Operating in Mixed Lubrication Regime
The journal bearings subjected to heavy load and slow speed operates in mixed lubrication regime causing contact between the interacting surfaces and resulting in wear. The complexity of wear behavior and lack of unifying theory/model make wear control very challenging. In the present research work, a methodology is outlined for the minimization of the wear of journal bearing operating in mixed...
متن کاملMixed Lubrication Effects in the Lateral Lubricating Interfaces of External Gear Machines: Modelling and Experimental Validation
This article presents a novel mixed-thermoelastohydrodynamic (TEHD) model for the lateral lubricating interfaces which exist between floating lateral bushings and gears in external gear machines (EGMs). The proposed model integrates the influence of surface asperities along with the fluid structure and thermal interaction in the interface, especially in the regions of very low film thicknesses ...
متن کاملOn the Fully Turbulent Regime in Hydrodynamic Lubrication
The long-standing classical theory of lubrication in the fully hydrodynamic regime is essentially traced back on the assumptions of (i) a relatively slender gap formed by two rigid surfaces that exhibit a (counter-)sliding (and “squeezing”) motion in the specific reference frame, (ii) a Newtonian lubricant, (iii) the neglect of inertia terms in the Navier-Stokes equations, and (iv) strictly lam...
متن کاملA phenomenological lubrication model for the entire Knudsen regime
Rarefied gas flows in thin film slider bearings are studied in a wide range of Knudsen numbers (Kn) at low Mach number (Ma) with the objective of developing simple physics-based semi-analytical models. A recently developed modified slip boundary condition for steady plane Couette flows and a generalized high-order velocity slip boundary condition, developed and validated earlier for pressure-dr...
