- Present paper shows the results of numerical solution Reynolds equation for laminar, steady oil flow in slide plane bearing gap. Lubrication oil is fluid with micropolar structure. Properties of oil lubrication as of liquid with micropolar structure in comparison with Newtonian liquid, characterized are in respect of dynamic viscosity additionally dynamic couple viscosity and three dynamic rotation viscosity. Under regard of build structural element of liquid characterized is additionally microinertia coefficient. In modelling properties and structures of micropolar liquid one introduced dimensionless parameter with in terminal chance conversion micropolar liquid to Newtonian liquid. The results shown on diagrams of hydrodynamic pressure in dimensionless form in dependence on coupling number N and characteristic dimensionless length of micropolar fluid A1. Presented calculations are limited to isothermal models of bearing with inflnite breadth. Especially, geometry schema of the slide Journal plane bearing gap, the dimensionless pressure distributions p1 in dependence on coupling number N2, the dimensionless pressure distributions p1 in dependence on characteristic dimensionless length of micropolar fluid, the dimensionless maximal pressure p1m in dependence on coupling number N, gap convergence coefficient are presented in the paper.
