摘要
对奥贝球铁车用480柴油机曲轴的生产研究表明,在适当的保护措施下,等温淬火后曲轴总体变形在精加工余量范围内,不影响成品曲轴精度.螺纹、键槽等在等淬后也不变形。可用先完成除粗、精磨外的所有机加工,再等温淬火,而后粗、精磨的方法生产奥贝球铁曲轴.试验用铜钼合金球铁(Mn<0.50％,Cu0.60～1.00％,Mo0.20～0.30％)可使直径60毫米的曲轴淬透,经380℃×60分钟淬火后机械性能达:O_b1101MPa,α_k141J/cm^2,δ_s=12.2％。
The manufacturing of ADI 480 diesel engine crankshaft -was studied. The results show that the deformation of crankshaft during austempering can be controlled by using proper protective measure, and the ADI 480 diesel engine crankshaft can be produced by Machining - Austempering-Precis ion work method.
