用牛头刨床加工螺旋锥齿轮,是在学习兄弟厂牛头刨床刨直齿锥齿轮的基础上改进的。一、主要结构1.专用铣头(图1)装在牛头刨床的滑枕上,铣刀盘装在铣头的主轴锥孔内,主轴可随滑套上下移动,由改变速度挂轮获得所需的速度。2.铣齿夹具(图2)安装在牛头刨床的工作台上。二、加工原理(图3)采用平顶齿轮原理,即在切齿过程中,假想有一个这样的平顶齿轮和被切 Machining spiral bevel gears with a shaper is an improvement on the basis of studying the sharpening bevel gears of a brother factory planing machine. First, the main structure 1. Special milling head (Figure 1) is mounted on the ram shaper ram, milling cutter mounted in the milling head spindle taper hole, the spindle can move up and down with the sleeve, the speed of change by the wheel to get the required speed. 2. Milling tooth fixture (Figure 2) is mounted on the workbench of the shaper. Second, the principle of processing (Figure 3) The principle of flat-top gear, that is, in the process of cutting teeth, it is assumed there is such a flat-top gear and cut
