摘　　要：变速箱齿轮工作时需齿轮油进行润滑和冷却,为此需在齿轮端面设计油槽。本文介绍了齿轮油槽的结构形式和对应的成形工艺,其中油槽热锻成形工艺方案较为经济,但需要具有下顶出机构和封闭行程的机械压力机类设备,以及能够很好控制下料重量一致性的精密剪床或高速圆盘锯来实现双面油槽热锻成形工艺。针对双面油槽齿轮成形中存在的油槽破齿和油槽不通缺陷原因进行分析,并提出改进方案。Transmission gears in the work need gear oil for lubrication and cooling, will be in the gear end faee design oil groove. This paper introduees lhe structure form of the gear oil groove and the corresponding fi）rming technology, in which the hnl forging process is more economical, but need to have under the ejection meehanism and closed stroke of the mechanical press equipment, and can realize double side oil groove of hot forging process the weight of material in good agreement under the control of the precision shearing machine or high-speed circular sawing. On the other side, the cause of broken teeth and barrier defects of the double side oil groove gear is analyzed, and the improved scheme is put forward.
