滚齿机上加工球面蜗杆的方法

Approach for Manufacturing Spherical Worm in Gear Hobber

基于对球面蜗杆副形成原理的分析和研究,给出了为满足加工球面蜗杆齿形要求的滚齿机的改进方法,提出了为保证蜗杆各项精度所要采取安装、找正、切齿加工等有效的工艺措施。通过实际切齿的验证,证明了在没有专用的加工设备、单件小批量时该方法可行有效。

The paper analyses and studies the formation principle of the spheri- cal worm, puts forward the renovation on gear hobber to satisfy the demand for manufacturing the tooth of the spherical worm, offers the effective technical measures on assembly, alignment and tooth cutting to guarantee each precision of the worm, which proves feasible while manufacturing single part and small amount without special facilities.
