| 中文摘要: |
| 随着汽车生产的大规模化，高效率、高质量、低污染、低成本的齿轮冷挤压制造技术越来越受到国内外学者和专家的关注，有限元分析和上限法等理论依据越来越多地被应用到齿轮冷挤压成形的工艺改进，闭式冷精锻和分流冷挤压成为直锥齿轮和圆柱直齿轮大批量生产的关键工艺。从理论研究和工艺研究两方面论述了汽车齿轮的冷挤压成形技术研究现状，并对其发展进行了讨论。 |
| 英文摘要: |
| With large scale of automotive manufacturing, high efficiency, high quality, low pollution, low cost cold extrusion processes of automotive gear are more and more concerned by scholars and experts.Finite element analysis method and theoretical upper limit are used in cold extrusion forming process improvement of gear, closed forging and divided flow cold extrusion become key technologies of shunt straight bevel and spur gears for mass production.The status of cold extrusion process of automotive gear from was discussed from theoretical and process research, trend was also discussed. |
