航天动力系统用精密齿轮箱的集成制造工艺

摘要

Taking the manufacturing of gearbox for a spaceflight power system as an example,in view of the short-term problems existing in the manufacturing process,from the process of deformation control and integrated processing fixtures,the numerical control integrated manufacturing technology of precision gear box parts for aerospace propulsion system is studied.The research results show that through the production of the appropriate parts of the product blank holder and the use of the tooling,the integrated manufacturing of the gear box can be realized.The research results have been wildly extended and applied to the manufacture of gear box parts for aerospace propulsion system.%以某航天动力系统用齿轮箱箱体的制造为例,针对其制造过程中存在的瓶颈短线问题,从加工过程中的变形控制以及集成加工工装装夹方案出发,对航天动力系统用精密齿轮箱箱体类零件的数控集成制造工艺进行了深入研究.研究结果表明,通过在产品坯料适当部位设置工艺夹台并结合工装的使用,可以实现齿轮箱箱体的集成制造.该研究成果在航天动力系统用齿轮箱箱体类零部件研制中得到广泛推广和应用.
