航空轴承国产化研制生产离不开航天精工的技术支持

中轴网轴承资讯：
行业周知，轴承是国内第一家针对航空航天机体轴承定位设计，采用系列品种齐全和航空航天机体配套、德国先进制造专业技术的创新产品。航天精工近年来已从单一的紧固件产品发展到紧固件、轴承、橡胶件、锚固件四大类品种。通过国际技术合作平台的商业模式创新，航天精工近年获取了德国现行航空轴承制造工艺和近200份欧美航空轴承技术标准，高起点开局、高标准开展和高质量推进为公司航空轴承国产化研制生产提供了良好的技术基础。
2016年11月24日，航天精工研制的各两个典型规格的自润滑关节轴承、杆端双列调心球轴承、带法兰盘单列球轴承顺利通过典型航空轴承国产化技术评审会。会议评审组听取了航天精工编制的项目总结报告及第三方鉴定试验合格报告，审查了相关技术文件，查看了生产现场，经过讨论和质询，认为研制的三种类型航空轴承完全符合相应欧洲航空轴承现行产品标准和技术规范的要求，形成了完整的工艺文件和质量控制文件，一致同意航天精工研制生产的此三种类型轴承通过技术评审。 此次评审项目中的自润滑关节轴承、杆端双列调心球轴承、带法兰盘单列球轴承均属于应用范围广、使用数量多的典型机体轴承(机体轴承是连接飞机机体各部位的关键基础件，是飞机机身结构的关节，飞机机体的所有运动都必须通过机体轴承的转动或摆动完成）。杆端双列调心球轴承和带法兰盘单列球轴承在国内首次完全按照欧洲现行产品标准和技术规范生产，并获得了国内权威第三方鉴定试验合格报告，其中的极限温度试验、沙尘试验、密封牢固性试验、轴向双向阶段性载荷试验等鉴定试验项目在国内尚属首例，开启了国内该类航空球轴承国产化的先河。
轴承事业部通过了厂内和外部第三方检测试验鉴定，完成了该科研项目任务书中的全部研制内容和技术指标。项目文件资料齐全，数据详实可靠，产品生产、检验过程中质量管控到位，符合公司质量管理体系要求。轴承事业部在项目研制过程中突破了一系列技术难点，形成产品图纸6套，规范类技术文件9份，加工工艺文件10余份，工装模具图纸100余份，受理3份发明专利和3份实用新型专利（已授权1份）的科研成果，为公司后续航空航天轴承的进一步国产化研制生产奠定了良好的技术基础。
