齿轮滚刀的刃磨一般应在半自动滚刀刃磨机床上进行,但因这种专门机床较少,所以大多数工厂只能用靠模、阔形齿托(即撑牙)、或专用夹具在工具磨床上进行刃磨。由于夹具的精度不高或操作误差,造成刃磨后滚刀的前角(刀齿沿前面的径向性)、螺旋槽等分(螺旋沟槽的圆周节距的等分性)和导程(螺旋沟槽导程或直槽的偏斜)等误差达不到要求。使滚刀的精度显著下降,严重影响被加工齿轮的精度和滚刀的使用寿命。我厂为解决滚刀刃磨的质量问题,在学习兄弟厂经验的基础上,通
Sharpening grinding gear hobbing should generally be carried out on a semi-automatic hob sharpening machine, but due to the relatively small number of specialized machine tools, most of the factory can only use the model, broad-width bracket (that is, supporting teeth), or special fixture Tool grinding on the grinding machine. Due to the poor accuracy or operating error of the jig, the rake angle of the rear hob (the radial direction of the cutter teeth along the front), the bisector of the helical groove (the equalization of the circumferential pitch of the helical groove) and the lead (Helical groove guide or straight slot deflection) and other errors can not meet the requirements. The hob’s accuracy dropped significantly, seriously affecting the accuracy of the gear being machined and hob life. I plant to solve the quality of hobbing grinding problems, based on the experience of brothers plant learning, through
