Improvement of the service life of mining and industrial equipment by using friction modifiers

Purpose. Enhancement of the performance, service life and sustainability industrial vehicles, mining machinery various equipment by reducing friction coefficient. Methodology. Laboratory research on assessing interaction pairs under external loading, rolling, sliding in dry conditions, as well influence modifiers. Industrial experimental studies performance indicators Findings. Actual diagrams depicting changes coefficient between contacting surfaces disc were obtained for four specific loading periods corresponding pressures 529, 374, 274 187 MPa. These measurements taken while discs experienced a 10 % relative slippage cyclic load during testing specimens, with presence repair-recovery compound called “Ideal” without it, using only friction. The new technologies “Ideal”, developed at Institute Geotechnical Mechanics named N. Poljakov National Academy Sciences Ukraine, provide an exceptionally low 0.04–0.005 ensure durability protective layer before failure, reaching 80–100 thousand cycles pressure 529 At 187–374 MPa, provides up to 1 million interaction. Originality. unique properties combination tribotechnical composition, which forms metal-ceramic, superhard, refractory, wear-resistant nanostructured metal base, have been established. This protection against wear, dynamic loads, thermal oxidative degradation, increases units 3–10 times. Practical value. Based results acceptance tests compound, decrease values extension highly loaded gear mechanisms 1.4–2.0 times It has found that provided helps reduce wear mass 20 tested samples, ensuring cleanliness lubricants increasing their operational lifespan saving maintenance costs.
