目前我国有些齿轮制造单位已大量采用冷精轧齿轮来代替剃齿工艺。象洛阳东方红拖拉机厂的装配分厂在一九七五年就有80％的齿轮采用了冷精轧这一新工艺,大大提高了劳动生产率。冷精轧齿轮有什么特点呢?它比剃齿有什么优点呢?我们知道剃齿的工作原理是在剃齿刀齿面开有小的齿槽,形成切削刃,剃齿时剃齿刀与被剃齿轮形成螺旋齿轮啮合,剃齿刀装在主轴上,被剃齿轮卡在工作台上的顶针间,剃齿刀的转动带动被加工齿轮旋转。由于螺旋齿 At present, some gear manufacturing units in our country have adopted a large number of cold-finished rolling gears instead of the shaving process. As the Luoyang Dongfanghong Tractor Factory assembly plant in 1979 there are 80% of the gear cold finish rolling the new technology, greatly improving labor productivity. What is the advantage of cold finished gear? What is the advantage over shaving? We know that the working principle of shaving is to open a small tooth groove on the tooth shaving face to form a cutting edge. When shaving, Was shaved gear formed spiral gear meshing, gear shaving cutter mounted on the spindle, the shaving gear stuck in the table between the thimble, shaving cutter rotation gear driven gear rotation. Due to the helical teeth
