一种平衡轴齿轮的加工方法
摘要：
本发明涉及一种平衡轴齿轮的加工方法，它包括以下步骤：(a)将原料钢棒切割成多个钢段，置于1085～1115℃的条件下加热软化，随后放入模具中墩粗成型；(b)对墩粗后的钢段进行冲压形成中孔，(c)将形成中孔的钢段浸入水中进行降温，随后去除其表面的氧化皮；(d)对钢段进行精加工即可。这样一方面能够在其表面形成氧化皮，另一方面能够使得钢段内部进行金相反应，最终提高平衡轴齿轮的强度和韧性。
摘要（英）：

The invention relates to a method for machining a balance shaft gear. The method comprises the steps of a, cutting a raw steel bar into multiple steel sections, heating and softening the steel sections at 1085-1115 DEG C, and then placing the steel sections in a mold for heading forming; b, punching the steel sections after heading to form center holes; c, soaking the steel sections provided with the center holes in water to be cooled, and then removing oxide skin on the surface of each steel section; d, conducting finishing machining on the steel sections. In this way, oxide skin can be formed on the surface, metallographic phase reaction can be conducted inside the steel sections, and finally the strength and tenacity of the balance shaft gear are improved.
