“…The conical journal bearing system is advantageous to use for the view point of lubricant flow rate, adjustability of clearance and space. [1][2][3] In recent times, many studies [4][5][6][7][8][9][10][11][12][13] related to conical bearing have been reported in the literature. Prabhu and Ganesan [4][5][6] studied the dynamic behavior of capillary compensated annular recess conical hydrostatic thrust bearings.…”

This article describes an analytical study to demonstrate the influence of micropolar lubricant on a four-pocket conical hybrid journal bearing system compensated with membrane restrictor. The modified Reynolds equation has been derived using Eringen’s theory of micropolar fluids with usual assumptions in cylindrical coordinates. The finite element modeling of the modified Reynolds equation has been made using Galerkin’s technique. The variation of bearing characteristics parameters for both Newtonian and micropolar lubricated bearings have been plotted with respect to radial load parameter for the chosen values of semi-cone angles, coupling number, characteristic length, and membrane compliance. The numerically simulated results indicate that micropolar lubricated bearing provides enhanced performance vis-à-vis Newtonian lubricated bearing.

“…These studies indicate that the performance of bearing system in terms of fluid film stiffness and damping coefficients significantly improves with membrane restrictor. The studies [5][6][7][8][9][10][11][12][13][14][15][16][17][18] are restricted up to Newtonian lubricant.…”

“…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 • .
