摘要
为实现非圆斜齿轮滚切加工,基于5轴联动滚切策略,应用运动学原理推导齿坯附加转动和滚刀附加转动2种方案的基本数学模型;采用工件等弧长、工件等转角和工件等极角3种方法简化该模型,构成6种滚切实现方案及实用模型;采用Matlab软件对6种模型进行五联动轴的(角)速度、(角)加速度动态性能分析,得出加工精度及效率高、动态品质综合性能较好的等弧长齿坯附加转动和等弧长滚刀附加转动2种最佳模型。经滚切试验验证了模型的正确性,齿面测试分析与仿真结论一致。
The application of non-circular helical gears has been restricted to its manufacturing techniques. To realize their hobbing process, based on the strategy of a five-axle linkage, two basic mathematical models of the schemes of work piece extra rotation or hob extra rotation were deduced according to the kinematic principle. The models were simplified based on the algorithms of the equal arc length or equal rotate angle or equal polar angle, which composed the six implementing schemes and functional models. The models obtained were analyzed about the dynamic property of the five synehronal axes, including both their velocities or angular velocities and their accelerations or angular accelerations, by using Matlab. Finally, the two optimization models that equal arc length ＆ work piece extra rotation and equal arc length ＆ hob extra rotation with high accuracy and efficiency were obtained, which have highly dynamic comprehensive performance. The models were demonstrated to be valid by hobbing testing, and the results between the testing of tooth flanks and computer simulations were in good agreement.
