通过VERICUT加工仿真验证了数控成形磨削法加工双圆弧齿廓弧齿锥齿轮的可行性。研究了数控成形法加工锥齿轮的刀具轨迹和圆弧齿廓弧齿锥齿轮的齿面方程,通过砂轮磨削面和齿面的接触条件式求出成形砂轮轴向截形;然后,提出数控成形磨齿机联动轴数的选取准则,并在VERICUT中建立机床、成形砂轮和毛坯的模型;最后,对双圆弧齿廓弧齿锥齿轮进行加工仿真,证明了数控成形磨削法可用于加工该类齿轮,为数控成形磨削法在锥齿轮上的应用提供了技术支持。
The feasibility of machining double circular arc profile spiral bevel gear by numerical control forming grinding method is verified by VERICUT machining simulation.The tool path of the bevel gear and the tooth surface equation of the circular arc profile spiral bevel gear are studied,the axial cutting shape of the forming grinding wheel is obtained by the contact condition formula of the grinding surface and the tooth surface of the grinding wheel.Then,the selection criteria of the number of axes of the CNC forming gear grinding machine are proposed,and the models of the machine tool,forming grinding wheel and blank are established in VERICUT.Finally,the machining simulation of the double circular arc profile spiral bevel gear proves that the CNC forming grinding method can be used to process such gears,technical support for the application of CNC forming grinding on bevel gears.
