Abstract
Способ обработки внутренних поверхностей заготовок гильз двигателей внутреннего сгорания, включающий пневмовибродинамическую обработку (ПВДО), отличающийся тем, что перед ПВДО производят черновое и получистовое хонингование с достижением шероховатости поверхности Ra=1,15…2,35 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 в пределах 0,22…0,24%.2. Способ обработки внутренних поверхностей заготовок гильз двигателей внутреннего сгорания по п.1, отличающийся тем, что ПВДО производят при минутной подаче инструмента S≤500 мм/мин и давлении сжатого воздуха в пневмосистеме, подводимого к инструменту, Р≤0,5 МПа.A method of processing the inner surfaces of the blanks of sleeves of internal combustion engines, including pneumo-vibrodynamic processing (LDPE), characterized in that before the LDPE they produce rough and semi-honing with achieving a surface roughness of Ra = 1.15 ... 2.35 μm, and then the LDPE of the inner surface of the sleeve with steel balls to obtain 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 the provision of the relative oil consumption for burning in ICE within 0.22 ... 0.24% .2 . The method of processing the inner surfaces of the blanks of liners of internal combustion engines according to claim 1, characterized in that the LDPE is produced with a minute supply of the tool S≤500 mm / min and compressed air pressure in the pneumatic system supplied to the tool, P≤0.5 MPa.
