在外协加工中,我们遇到一些与刨齿刀压力角不同的直齿圆锥齿轮,如压力角α=14.5°,由于Y236型刨齿机上通常只备有20°压力角对刀规,也就是说只能加工20°压力角的直齿圆锥齿轮。在加工过程中,我们通过改变产形齿轮的节锥角,从而引起轮齿端面压力角变化,来实现加工与刨齿刀压力角不同的直齿圆锥齿轮的方法。经使用效果可以,从而做到不需要重新设计制造14.5°压力角的 In the outsourcing process, we encountered some with a gear tooth pressure angle of the spur bevel gear, such as the pressure angle α = 14.5 °, because Y236 type gear machine usually only has 20 ° pressure angle on the knife, that is, That can only process 20 ° pressure angle spur bevel gear. In the process of machining, we can change the pressure angle of tooth surface by changing the section cone angle of the forming gear to realize the method of machining the spur bevel gear with different pressure angle. The effect can be used, so do not need to re-design and manufacture of 14.5 ° pressure angle
