Abstract
The influence of dynamic viscosity of working liquids И-20А, МГЕ-46В, ВМГЗ on the lubrication of plunger pairs of axial-piston pumps of construction equipment is considered in the article. Based on the existing classification of lubricant types, a mathematical model is obtained to determine the effective viscosity, which corresponds to the transition of the plunger pair from the boundary lubrication regime to the semi-liquid mode. The obtained model takes into account the geometric parameters, the speed of rotation of the pump shaft and the size of the dimensionless criterion — the relative thickness of the lubricating film. The calculation of the change in the effective viscosity from the angle of rotation of the shaft for a plunger pair of an axial-piston pump with an inclined disk.

Что время пребывания пар трения в режиме граничной смазки определяет величину их суммарного износа. Как видно из зависимости (2) интенсивность износа трибосопряжений, при прочих равных условиях, обратно пропорциональна квадрату толщины смазочной пленки и пропорциональна динамической вязкости в степени 1/6.
