Abstract

Способ обработки внутренних поверхностей гильз тракторных и комбайновых дизелей в ремонтном производстве, включающий растачивание и пневмовибодинамическую обработку (ПВДО), отличающийся тем, что перед ПВДО производят однократное хонингование с достижением шероховатости поверхности Ra≤2,5 мкм, а затем ПВДО внутренней поверхности гильзы стальными шарами с получением шероховатости Ra≤0,5 мкм, средней глубины впадин R≤1 мкм, относительной опорной длины профиля поверхности t=85%, с обеспечением относительного расхода масла на угар в ДВС 0,35…0,40%.A method of treating the inner surfaces of sleeves of tractor and combine diesel engines in repair production, including boring and pneumo-dynamic treatment (LDPE), characterized in that before the LDPE, they perform single honing with a surface roughness of Ra≤2.5 μm, and then the LDPE of the inner surface of the sleeve with steel balls with obtaining a roughness Ra≤0.5 μm, the average depth of the troughs R≤1 μm, the relative reference length of the surface profile t = 85%, with a relative oil consumption for burning in ICE of 0.35 ... 0.40% .
