Opis:
The topic of the presented article aims to demonstrate a new principle of hydrodynamic lubrication in mechanical, non-isothermal and electro-magnetic fields. In this article is presented hydrodynamic slide journal bearing in electromagnetic field. The aim of this article is a new general analytical and numerical solution determined the influence of the electro-magnetic field on the temperature distribution in the internal surfaces of the slide-bearing sleeve and pressure distribution in bearing gap. To the research methods and materials used in this article realization belong: the Mathcad 15 Professional Program and new semi-analytical methods applied for theory of hydrodynamic lubrication extended to the curvilinear orthogonal surface and coordinates. Particular solutions are introduced to the cylindrical coordinates. To the obtained results of lubrication of movable sleeve surface belong the increments of the bearing load carrying capacity during the presence and absence magnetic induction field in the case if non-Newtonian lubricant features and constant temperature are taken into account. Simultaneously are observed the increments of the bearing load carrying capacity during the presence magnetic field and Newtonian lubricant. Temperature increments (decrements) without and with magnetic field lead to the hydrodynamic pressure decrements (increments). Moreover are assumed simultaneously the temperature T and oil dynamic viscosity variations in length, width and bearing gapheight directions. From this assumption follows, that the energy equation must be solved simultaneously with the equations of motion i.e. consequently with pressure equation where viscosity depends on temperature and temperature depends on the coordinate in gap height direction.
