面齿轮传动具有突出的优点,在航空领域具有广阔的应用前景。为提高面齿轮的加工效率,针对面齿轮球形滚刀及滚齿加工进行了研究。根据面齿轮传动原理,得到了面齿轮插齿成形的型面。研究了从圆柱齿轮向球形滚刀基蜗杆演变的过程,分析了球形滚刀的成形方法,推导了球形滚刀基蜗杆的型面方程和螺旋升角。建立了球形滚刀加工面齿轮的坐标系,推导了球形滚刀加工面齿轮的型面,利用VERICUT对2个实例进行了加工仿真,并进行了相应的实际加工试验和检测,仿真和试验结果表明球形滚刀可用于面齿轮的加工。
Surface gear drive has outstanding advantages in the field of aviation has broad application prospects. In order to improve the processing efficiency of face gear, the research on face gear hobbing and hobbing is studied. According to the principle of face gear transmission, the profile of face gear gear shaping is obtained. The evolution process of worm gear from spur gear to spherical hob was studied. The forming method of spherical hob was analyzed, and the equation of profile and helix angle of spherical hob based worm gear was deduced. The coordinate system of gear hobbing spherical surface hob was established, and the profile of gear hobbing spherical surface hobbing gear was deduced. Two examples were simulated by VERICUT, and the corresponding actual machining test and testing, simulation and test results Show spherical hob can be used for face gear machining.
