长锥距弧齿锥齿轮的加工参数设计与加工试验

Machining Parameters Design and Machining Experiment of Long-cone-distance Spiral Bevel Gear

由于其节锥距很大,常规方法加工长锥距弧齿锥齿轮需要大规格的机床及铣刀盘,难度较大。利用齿面接触区预控技术,设计齿轮副的加工参数,精确建立齿轮副的三维模型,模拟被加工齿面的接触状况。利用卧式加工中心,规划数控加工程序,进行长锥距弧齿锥齿轮的加工试验。结果表明,设计合理的加工参数,规划数控加工程序,在卧式加工中心上可以实现长锥距弧齿锥齿轮的加工。

For its cone distance dimension is very large, long - cone - distance spiral bevel gear is milled on the large scale special purpose machine tool generally, and the process is difficult to realize. Using pre - control technique of the tooth contact beatings, the gear machining parameters are designed, the precision gear 3D model is established, and the contact situation between the mesh surfaces is simulated. Based on the horizontal machining center, the NC program codes are compiled to experiment machining process of the long - cone - distance spiral bevel gear. The experiment results show that the long - cone - distance spiral bevel gear could be machined on horizontal machining center.
