“…It is shown that the same result can be obtained by a simple un-directional flow analysis. T.Jayachandra Prabhu and N.Ganesan [3] have studied effects of tilt on the characteristics of multirecess hydrostatic thrust bearings under conditions of rotation and no rotation. The dimensionless load, flow, stiffness and damping were obtained and plotted for a range of the tilt parameter for experimentally useful aspects ratios.…”

A theoretical comparative study concerning performance of a constant flow hydrostatic thrust bearing having multi-circular recess and sector recess is described. The Computational Fluid Dynamics and the Finite Volume Method have been used to compute the characteristics of a constant fluid hydrostatic thrust bearing with circular and sector recesses. The performance has been compared, namely, recess pressure, pressure distribution and oil flow rate, on the basis of the same pocket area and the same pocket number. The results demonstrate that bearing recess shape has a great influence on the behavior of the hydrostatic thrust bearing. The computed results indicate that to get an improved performance from a constant flow hydrostatic thrust bearing, a proper selection of the geometric shape of the recess is essential.

“…Conical journal bearing system supports both radial and axial load simultaneously and also has the advantage of clearance adjustability. [1][2][3] In recent years, many researchers [4][5][6][7][8][9] have focused their research efforts in the emerging area of conical journal bearing system. Needless to mention, lubricant plays a key role on the performance of a bearing system.…”

The present paper investigates the influence of micropolar lubrication on the stability of a constant flow valve compensated multi-recess conical hybrid journal bearing system. Eringen's micropolar fluid theory has been used to model the micropolar lubrication in a fluid-film bearing system. The modified Reynolds equation of the micropolar lubricated bearing system has been solved using finite element method. Performance characteristics parameters of four pocket hybrid journal bearing system have been computed for the values of semi-cone angle 10°, 20°and for the judiciously selected micropolar parameters. Numerically simulated results indicate that the value of stability threshold speed margin gets increased substantially with the use of micropolar lubricant vis-à-vis Newtonian lubricant.

“…These bearings are also more economical for the machining point of view [1,2]. In recent times, many researchers have focused their studies [2][3][4][5][6][7][8][9][10][11][12][13][14][15] concerning the analysis and design of conical bearings.…”

“…It was reported that axial preload and lobe depth affect the working clearance and the fluid film stiffness of the bearing significantly. Prabhu and Ganesan [4,6,7] analyzed the dynamic stiffness characteristics of capillary compensated annular recess conical hydrostatic thrust bearings. In their study, they discussed the conditions of tilt, eccentricity, and rotation.…”

The present paper deals with a theoretical analysis of 4-pocket capillary compensated conical hybrid journal bearing system operating with micropolar lubricant. The modified Reynolds equation for a conical journal bearing system operating with micropolar lubricant has been derived. In the present study, Eringen's micropolar theory has been used to model micropolar lubrication in cylindrical coordinate system. The study has been carried out for the different values of micropolar parameters, that is, characteristic length (l) and coupling number (N). The conical bearing configurations having semicone angle 10 • , 20 • , 30 • , and 40 • have been studied. The study suggests that micropolar lubricant offers better performance vis-á-vis Newtonian lubricant for bearing configurations having values of semicone angle 10 • and 20 • .
