焊接齿轮的热处理工艺研究

Study on Heat Treatment of Welded Gear

通过对中碳调质钢焊接齿轮采取焊前低调、焊后留磨量高调热处理工艺的研究实践,既保证了产品性能和变形量的要求,又简化了锻造工序、节约了材料、有利于多规格的批量生产,现已成功地应用于生产实践之中。

By practice of low temperature quenching and tempering before weld and high temperature quenching and tempering after weld for medium carbon,hardened and tempered steel welded gear,shows that this heat treatment processing not only satisfies with products performance and deformation requirement,but also simplifies forging,saves materials,which is suitable for batch production and has been used in production practice successfully.
