齿轮滚刀综合测量仪是检查齿轮滚刀的齿形、齿距、刀齿前面的径向性、容屑槽的圆周齿距和螺旋槽的导程等齿轮滚刀各要素的专用量仪。齿轮滚刀各要素的误差将会直接给被加工齿轮带来误差,因为齿轮的齿形由滚刀的切削刃形成,切削刃应具有正确的形状和符合要求的排列,切削刃对滚刀轴心线的相对位置也要符合要求。所以,不论对新制或重磨后的滚刀,其切削刃都应该分布在基本蜗秆的表面上,如果切削刃离开基本蜗杆的表面,就会引起被加工齿轮的齿形误差和尺寸误差。
Gear Hob comprehensive measuring instrument is to check the hob hob gear, pitch, the radial front of the tooth, the chip groove circumference pitch and helical groove lead and other gear hob all the elements of the special measuring instrument. The error of each element of the gear hob will directly bring errors to the gear to be machined because the tooth profile of the gear is formed by the cutting edge of the hob and the cutting edge should have the correct shape and the required arrangement. The relative position of the heart line should also meet the requirements. Therefore, the cutting edge should be distributed on the surface of the basic worm shaft both freshly ground and regrind hobs. If the cutting edge leaves the surface of the basic worm, it will cause toothed and dimensional errors of the to-be-machined gear.
