花键滚铣刀是一种重要的金属切削工具,它主要用于制造花键轴,在机床制造及汽车制造等工业中是不可缺少的。目前我国的机床制造工业已迅速地发展起来了,因此这种工具的需要量也日渐增加;但我国在现时,这方面的标准工具尚不多见。今就花键滚铣刀的设计问题作一比较详细的介绍,以供各工厂参考。一、花键滚铣刀的切削情形普通花键滚铣刀(以下简称铣刀)是按展成法的原理工作。铣刀就像是齿条,被切削的花键轴(以下简称键轴)如同齿轮。键轴与齿轮在相对运动时,键轴的节圆沿着其轴线有辅助的轴向运动,而键轴与铣刀的运动就是主要运动。在工作时,铣刀对于键轴占有一系列的位置,並以刀齿两侧绕行
Spline hob is an important tool for metal cutting, it is mainly used to make spline shaft, in machine tool manufacturing and automobile manufacturing industry is indispensable. At present, China’s machine tool manufacturing industry has developed rapidly, so the demand for such tools is also increasing. But at present, the standard tools in this area are still rare in our country. This spline hob cutter design issues for a more detailed introduction, for the factory reference. First, the case of spline hob cutter General spline hob cutter (hereinafter referred to as cutter) is based on the principle of work into law. Milling cutter is like a rack, the spline shaft is cut (hereinafter referred to as the key shaft) as a gear. When the key shaft and the gear are in relative movement, the pitch circle of the key shaft has auxiliary axial movement along the axis thereof, and the movement of the key shaft and the cutter is the main movement. At work, the milling cutter occupies a series of positions with the key shaft and bypasses the sides of the knife
