大型齿轮无模铸造的快速研制

Rapid Development of Large Gear Made by Patternless Casting

基于快速铸造技术研究了大型齿轮的快速研制过程。针对直径1800 mm大型齿轮中轮齿的分型位置,采用"整体齿"的铸造工艺,通过浇注系统设计、分型设计、铸型加工、坎合组型、熔炼浇注等过程对大型齿轮铸件进行快速研制。结果表明,采用"整体齿"的技术方案研制大型齿轮铸件生产周期短,生产成本低,铸件结构精度高,铸件表面质量好,具有良好的推广应用价值。

The rapid development of large gear was studied based on rapid casting technology.Aiming at the parting position of gear teeth in large gear with diameter of 1800 mm,the casting technology of"whole tooth"was adopted,and the development of large gear castings was carried out rapidly through pouring system design,parting design,casting machining,joint forming and melting casting.The results show that the technical scheme of"integral tooth"for the development of large gear castings has the advantages of short production cycle,low production cost,high casting structure precision and good casting surface quality.
