Analytical technique for predicting the value of micropolar lubrication criteria providing stable operation of a radial slide bearing

An analytical technique is proposed for forecasting the values of the dimensionless micropolar lubricant criteria providing a stable operation mode of a radial bearing. On the basis of the analytical relations obtained for the dimensionless supporting force and the dimensionless friction torque, the optimal intervals for variation in the dimensionless micropolar lubricant criteria are determined; additionally, the values for the efficient viscosity and the volumetric concentration of the disperse phase are found. The problem of the wedge motion inside the bearing is solved; the bearing is shown to operate more stably when working on the micropolar lubricant than on the Newtonian one.
