The paper considers radial friction bearings of finite length, the fixed hub of which consists of a supporting part, a porous layer, and a liquid material. The existing methods of design calculations of such bearings are very approximate, since they do not take into account the nonstationary operating conditions of the shaft and the influence of the method of supplying the lubricant. The influence of these parameters on the stable operation of the triboconjugation under consideration is shown. In addition, as a result of the studies, the effect of multifunctional additives for lubricants in the form of nanoscale particles was established by studying the phase diagrams of systems of ceramic materials–oxides and condensed phosphates. This approach makes it possible to actively control the coefficient of friction by changing the state of surface films with boundary friction. |
