轴承网—全纤维柴油机曲轴制造技术能力再创新
发布日期：2024-02-07
轴承网报道，中国南车资阳机车公司的“大中型船用柴油机曲轴制造工艺开发”等三项工艺开发成果通过四川省科技厅组织的成果鉴定。其总体技术水平均达到国际或国内领先，将有力改善我国大中型船用柴油机制造中“以轴定机”、曲轴长期依赖进口的状况。
曲轴是柴油发动机中承受载荷、传递动力的重要零部件，其性能水平直接影响发动机整体性能。轴承网记者获悉，为提升从材料选取到加工成品的曲轴自主研制、生产能力，2008年起我国最大的大功率中高速发动机曲轴供应企业南车资阳公司，启动大中型船用曲轴制造工艺开发、RR曲轴镦锻装置精化曲轴锻件工艺、曲轴热处理控时淬火技术应用研究。
作为国内全纤维曲轴研制主导单位之一，企业通过优选、优化原材料、改进工艺等，在国内首次实现RR曲轴镦锻装置预上弯技术、曲线分模技术设计曲柄臂锻件、卧式调质淬火等新技术，及车铣中心的复合加工、新型磨削和具有自主知识产权的抛光装置等新工艺，解决了全纤维曲轴制造中材料、锻压、热处理、机械加工等制造链条的一系列难题。轴承网得知，经专家评审，其新工艺、技术不仅提高了生产效率和产品质量，而且使每支曲轴的材料利用率提高了10%至14%。
通过科技攻关，该企业目前全面掌握了大中型船机曲轴全制造链条的关键技术，近年来已成功试制并量产10余种大型曲轴，其性能及精度达到进口产品水平。目前，该企业研制的曲轴种类已涵盖机车、大中型船机、压缩机、高压泵曲轴等领域40多个系列100多个品种，并向美国、德国、日本等国出口3000多支。
