| Summary: | The research includes the development and analysis of a mathematical model
of the micropolar lubricant flow in the working gap of a modified design of an
infinite radial sliding bearing, taking into account compressibility and the effect of
pressure on the rheological properties of the lubricant. Considering the lubricant
compressibility, the authors took into account the dependence of the viscosity
and density of the lubricant on high pressure. Under typical conditions of radial
bearings, significant loads can cause changes in the properties of the lubricant,
which affects its ability to form a stable lubricating film. Therefore, the introduction
of compressibility parameters into the model allows more accurately predicting the
behavior of the lubricant and the effectiveness of lubrication in various operating
modes. The new model has been developed by the well-known equations of the
flow of a micropolar lubricant, the continuity and the state equation. A comparative
analysis of the numerical result of theoretical models and experimental research is
carried out. Thus, the research represents a significant contribution to the field of
radial bearings sphere. The obtained results can be used for further improvement of
bearing designs, which allows increasing their reliability and durability of mechanical
engineering. |
