摘要
针对采用五刀法进行小模数螺旋锥齿轮加工时效率较低,采用两刀法加工时接触区不易于保证的问题,提出了采用双滚法进行小模数螺旋锥齿轮切齿的方法。设计了数控双滚加工流程,建立了刀位计算模型和自动对刀的相位补偿模型;开发了双滚加工数控软件,实现了在一个切齿加工循环中通过两次滚切完成齿轮副凹凸两面的加工,无需进行手动对刀处理。开展了切齿实验及滚动检查实验,验证了应用双滚加工方法进行小模数螺旋锥齿轮加工可在保证良好的接触状态的同时获得较高的加工效率。
Aiming at the low processing efficiency of spiral bevel gears with small modulus by means of five-step method and the difficulty of obtaining good contact area by Two-step method,a cutting method of spiral bevel gears with small modulus by using double rolling is presented.Designing NC double rolling process,the calculation model for tool position and the phase compensation model for automatic tool alignment are established,NC software for the double rolling is developed,the processing of concave and convex sides of gear pair through two rolling in a cutting cycle without manual tool alignment is realized.The experiments of cutting teeth and rolling inspection have been carried out.The results show that the double-rolling method can ensure the good contact and obtain the high processing efficiency for spiral bevel gears with small modulus.
