我单位在加工一正交弧齿锥齿轮的主动轮时,根据切齿调整数据进行粗切,再进行精切凸面、精切凹面的加工工序。粗切后,该主动轮的齿面呈正常收缩态,但收缩比例较大,齿大小端精切余量不均匀,以改于在精切凸凹面以后,该主动轮的大端齿槽留下一条长约8mm、厚约1mm。高约1.8mm的肋。要使精切后不留肋,可以在Y225机床上进行加工,粗切至齿深或超齿深0.20mm,但此时,该主动轮的齿小端已无精加工余
When machining the driving wheel of an orthogonal spiral bevel gear, our unit performs rough cutting according to the cutting gear adjustment data, and then carries out the processing steps of fine cutting convex surface and fine concave surface. Rough cutting, the driving wheel tooth surface was normal contraction, but a larger proportion of shrinkage, the tooth size of the end of the margin of uneven, to change in the precision concave and convex after the drive wheel of the big end of the tooth retention The next length of about 8mm, thickness of about 1mm. Ribs about 1.8mm tall. To make the fine cut without leaving ribs, you can Y225 machine processing, rough cut to the tooth depth or super-tooth depth 0.20mm, but this time, the capstan tooth tip has no finishing
