Definition OF POWER LOSS IN THE HYBRID BEARING with Oil-Mist Lubrication

S.V. Nikitin, Y.V. Коvezа

In work analytical dependence with application of similarity criterion for definition of power loss in hybrid bearing with oil-mist lubrication is offered. Feature of the completed research that the air-oil mist was considered as the homogeneous medium with averaged parameters. Having carried out the comparative analysis of experimental data for bearings with balls from nitride of silicon and from bearing steel, it is shown that the techniques received for all-metal bearings, can be applied practically without changes and to hybrid bearings in an investigated range of parameters. On this basis the general analytical dependence was deduced.

Key words: shaft bearing, ball bearing, oil-mist lubrication, ceramic balls, similarity criterion, friction, power of a friction, hybrid bearing.
