Transition from Boundary Lubrication to Hydrodynamic Lubrication of Slider Bearings
The transition from boundary lubrication to fully hydrodynamic lubrication is investigated for air-lubricated slider bearings using the electrical resistance method. Intermittent contacts are shown to exist even under conditions for which the numerical solution of the Reynolds equation or white light interferometry predicts steady state spacings in the spacing region from 0.125 to 0.25 pm. The ...
متن کاملTribology of Journal Bearings Subjected to Boundary and Mixed Lubrication
The purpose of this research paper is to examine the tribological characteristics and issues related to journal bearings under boundary and mixed lubrication conditions during shaft startup, shutdown, and low speeds. The key issues and problems related to journal bearings, most notably wear, are discussed as well as the subsequent issues created in the field. The mechanical analysis of the load...
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 کاملOn the future of controllable fluid film bearings
This work gives an overview of the theoretical and experimental achievements of mechatronics applied to fluid film bearings. Compressible and uncompressible fluids are addressed. Rigid and elastic (deformable) bearing profiles are investigated. Hydraulic, pneumatic, magnetic and piezoelectric actuators are used. The ideas of combining control techniques, informatics with hydrodynamic, thermo-hy...
متن کاملhydrodynamic analysis of circular and non-circular journal bearings using generalized differential quadrature method
this paper presents the application of the generalized differential quadrature (gdq) method for the hydrodynamic analysis of circular and noncircular, two lobe and three lobe, journal bearings. gdq is a simple, efficient, high-order numerical technique and it uses the information on all grid points to approach the derivatives of the unknown function. the effectiveness of the solution technique ...
