METHOD OF RECONDITIONING OF THE OUTWORN HOLES OF THE FIXED JOINTS |
摘要 |
FIELD: mechanical engineering; methods of reconditioning of the machines components. ^ SUBSTANCE: the invention is pertaining to the field of mechanical engineering, in particular, to reconditioning of the machines components and may be used for restoration and increasing of reliability of the blocks of the "pivot bolt - the aperture under the pivot bolt" of the beams of the cars forward axles. At the wear of the holes up to 0.4 mm per the diameter for the diameter deposition of the coating made out of copper or its alloys is carried out by the electric spark treatment at the impulses power of 0.5-1.5 J, and specific time of the treatment of 2.5-3.5 minute/cm2. At the wear of the holes from 0.4-1 mm per the diameter - deposition of the layer of the coating is conducted by the electric spark treatment with the specific time of the treatment of 2.5-3.5 minute/cm2. In the beginning they deposit the layer of the coating made out of the medium-carbon steel or the high-carbon steel at the impulses power of 1.5-2.5 J, and then - the layer of copper or its alloys at impulses power of 0.5-1.5 J. The invention ensures the decreased fretting and the adhesion interaction of the reconditioned holes of the fixed joints. ^ EFFECT: the invention ensures the decreased fretting and the adhesion interaction of the reconditioned holes of the fixed joints. ^ 2 cl, 2 tbl |
