Influence of couple stress lubricants on hole-entry hybrid journal bearings
Nathi Ram1.
The analysis of symmetric and asymmetric hole-entry hybrid journal bearings under couple stress lubrication is presented in the present investigation. Equation of Reynolds theorem has been modified for the couple stress lubricant’s flow in the journal and bearing’s clearance space and Newton Raphson and finite element techniques are used for solving this Reynolds equation. For different parameter values of couple stress lubricant and for external load, the outcomes are simulated. Presented result show that at constant load for hybrid journal bearings, couple stress lubricant influences the increase in the value of minimum thickness of fluid film, coefficients of stiffness and damping. It is also observed that for asymmetric bearing under couple stress lubricant, the threshold speed value increases by 14.47% for lower external load when operates couple stress parameter value 5 than similar bearing under Newtonian lubricant.
