指形刀架是滚齿机的重要附件,刀架质量对产品加工影响重大。我厂WI Y 3 J滚齿机指形刀架,使用不足一年壳体从微调刻度方向断裂,为此,我们进行了实践分析研究,改革成如图所示结构,把齿轮减速传动改为内齿轮直接传动,取消微调,采取圆锥外形,铣削内外齿通用,原转速40～445转/分,改为75～837转/分。经使用证明:结构简单、制造容易、
Finger-shaped knife hobbing machine is an important annex, the quality of the knife holder significant impact on product processing. I plant WI Y 3 J hobbing machine finger turret, the use of less than one year shell from the fine-graded direction rupture, for which we conducted a practical analysis of the reform into the structure shown in the figure, the gear reducer to internal gear Direct drive, to cancel the fine-tuning, take the conical shape, milling the internal and external teeth common, the original speed of 40 ~ 445 rev / min, changed to 75 ~ 837 rev / min. Proved by the use: simple structure, easy to manufacture,
