The article covers the concepts, definitions and correlations of parameters of worn surfaces
within the coordinate system of relative pressures and convergences of interacting elements of
construction machines.
The authors provide their findings based on the research of microtopographic and tribological
engineering parameters of scoop hinges of construction drags and fused crushing plates of jaw
crushers. As for the drag hinges, the friction pair is to include steel 110Г1ZL and X-5 padding that
demonstrates high resistance to friction (=1.04) and low temperature of frictional heating (ƒ= 90
°C). Mobile plates of jaw crushers need electrodes VSN-9 and TsN-16 for padding purposes, as they
demonstrate the biggest frictional fatigue values (= 2.76 and 2.62, respectively) and insignificant
temperature of heating of friction surfaces (9.4 and 4.9 °C). Electrodes TsN-16, T-590 and KBKh-45
are recommended for fixed plates.
Microtopographic parameters of worn friction surfaces are used to analyze the main tribological
engineering parameters of operating elements and joints of construction machines and items of
equipment.
