Linear harmonic vibration during machining of a conical journal may produce micron order
undulations on outer surface of journal. Further, a lubricant comprising of long chain polymer …

A horizontally supported Jeffcott rotor system (JRS) is analyzed to determine the effect of
several important factors on the horizontal and vertical oscillations of the JRS. These factors …

Various anti-wear and anti-corrosion coatings are applied on the surface of journal and
bearing to maximise service life of a bearing system. These coatings influence the wettability …

In a MHCJB (multi-recessed hybrid conical journal bearings), the orientation of the pockets
affects the oil film pressure dispersion in the clearance space of bearing thereby it affects the …

This paper investigates the influence of rotor coaxiality error on spindle accuracy under
different operating conditions in the precision hydrostatic spindle with a mid-thrust bearing …

Polymer based additives with long chain of suspended particles in oil retain polarity effect in
the presence of couple stresses. Further, at high speed of journal bearing, the oil film …

Purpose The present paper aims to analyse the synergistic effect of pocket orientation and
piezo-viscous-polar (PVP) lubrication on the performance of multi-recessed hybrid journal …

In oil film journal bearings, the solid-liquid interfaces are susceptible to velocity slippage due
to several factors such as low oil viscosity near solid surface, molecular slippage or …

This paper presents an original theoretical investigation of the steady‐state and dynamic
characteristics of foil journal bearings lubricated with contaminated air taking into account …

Considérés comme des éléments de machines modernes, les paliers hydrodynamiques et
aérodynamiques sont largement utilisés comme organes de guidage à cause de leur …
