齿刀可以加工直齿和斜齿的内、外圆柱齿轮,生产效率高、加工表面光洁。此外,还有加工精密蜗轮用的蜗轮剃齿其基本蜗杆的类型和参数均应与蜗轮相匹配的工作蜗杆相同。它与齿轮剃齿一样,在螺旋面上开有许多窄的沟槽,以形成切削刃并容纳切屑。蜗轮剃齿难于制造,只有在加工精度要求很高的蜗轮时才使用。
The tooth cutter can process the inner and outer cylindrical gear of the straight tooth and the helical tooth, and the production efficiency is high, the processing surface is smooth and smooth. In addition, the type and the parameters of the worm gear shaving for the precision worm gear must be the same as that of the worm gear. It is the same as the gear shaving, there are many narrow grooves on the spiral surface, to form the cutting edge and to hold the chip. Worm gear shaving is difficult to manufacture, only when the machining accuracy is high.
齿刀是直齿和斜齿渐开线圆柱齿轮的一种精加工刀具。 剃齿时的切削刃沿工件齿面剃下一层薄金属,可以有效的提高被剃齿轮的精度和齿面质量; 并且加工效率高,刀具寿命长,是成批,大量生产中等精度圆柱齿轮时,应用最广泛的一种加工刀具。
Gear shaving cutter is a kind of finishing tool of straight tooth and helical involute cylindrical gear. Shaving cutting edge along the workpiece gear shaving surface under a layer of thin metal, can effectively improve the gear shaving accuracy and tooth surface quality; and has high processing efficiency, long life of cutter is, a lot of production medium precision cylindrical gears, the most widely used a processing tool.
齿面上开有许多形成切削刃的窄槽,按螺旋齿轮啮合原理加工工件的齿轮形齿轮加工刀具。在加工时,刀具从齿轮的齿面上切下胡须状的细切屑用于在滚齿、插齿(见齿轮加工)后对轮齿进行精加工。常用的盘形剃齿刀像一个淬硬的斜齿圆柱齿轮,齿面上的沟槽有两种形式:一种是在整个齿圈上开有圆环形或螺旋形的通槽,槽的截面可以是矩形,也可以是梯形用钝后只刃磨前面(槽部),齿形和外径都不改变,由于通槽不能做得太深,只适用于模数小于1.75毫米;另一种为两侧面的沟槽不通,是用梳形插刀分别插出来的,为使插刀能够退刀,在每个齿的齿根处钻有倾斜的小孔。这种剃齿用钝后需重磨齿形和齿顶圆柱面。 剃齿为了减小每个齿的切削负荷,剃齿的误差将复印到被加工齿轮上去。为了使工件得到正确的渐开线齿形,齿刀的齿形应经过修正,在大量生产中都是通过实验的方法来决定剃齿的齿形修正曲线。
The tooth surface is provided with a narrow groove which forms a cutting edge, and the gear shaped gear processing cutter of the work piece is processed according to the principle of the helical gear meshing principle. In the processing tool from the gear tooth surface cut beard like fine chip used in gear hobbing, gear shaper (see gear machining) on teeth for finishing. Inclined to a commonly used disk-shaped shaving knife as a hardened helical cylindrical gear, tooth surface grooves have two forms: one is in the ring gear with circular or spiral shaped through groove, the groove section can be rectangular, can also is a ladder with a blunt blade grinding front (slot), tooth shape and diameter does not change due to the through groove can not be done too deep, only suitable for module is less than 1.75 mm; the other two sides of the groove impassability, is with the comb shaped in knives are respectively inserted out, in order to make the knife knife back in each tooth root is drilled with holes. It is necessary to re grind the tooth shape and the top of the cylindrical surface after the shaving. In order to reduce the cutting load of each tooth, the error of gear shaving will be copied to the gear to be processed. In order to make the workpiece get the correct involute tooth profile, the tooth profile of the gear cutter should be modified, in a large number of production, through the experimental method to determine the tooth profile modification curve.
