摘要: 齿轮倒棱是一种采用特殊刀具对齿轮棱边进行切削或挤压成形的加工方法,能够减少齿轮棱边毛刺脱落和应力集中损伤齿面等问题,目前已成为新能源汽车高性能齿轮加工中必不可少的工艺。基于产形线与平面齿廓双自由度啮合滚棱加工原理,提出了一种圆柱齿轮端面齿廓滚棱刀具设计方法。通过建立刀刃曲线与端面齿形的双自由度滚切啮合几何学模型,阐述以齿廓倒棱平面为基准的滚棱刀具刃形计算方法;通过建立滚棱刀具刃扫面与被加工齿面展成运动关系,分析滚棱刀具参数与安装参数对倒棱结果的影响规律,并提出滚棱刀具侧后螺旋面不产生切削干涉的数值分析方法;通过建立滚棱刀具重磨误差分析模型,讨论滚棱刀具的重磨厚度变化对倒棱一致性的影响;最后,仿真加工与滚棱切削试验验证了所述滚棱加工方法的可行性。研究结果为圆柱齿轮滚棱工艺优化与刀具设计提供了理论依据。

Abstract: The process of gear chamfering is widely employed in manufacturing to effectively eliminate or roll sharp edges from gear parts using a specialized cutter, thereby reducing burrs and minimizing stress concentration damage on the tooth surface. In recent years, gear chamfering has become an essential step in high-performance gear manufacturing for new energy vehicles. A chamfer cut method for cylindrical gears is proposed based on the principle of tooth profile generation by a cutter edge with two-parameter. By establishing a geometric model of the tooth profile generated by the cutter edge with two-parameter, we calculate the chamfering cutter edge and analyze its influence on the results by considering its relationship with the sweeping surface of cutter edges and the gear tooth profile. A numerical method is proposed to analyze involute helicoids of the chamfering cutter without cutting interference. Additionally, how variations in regrinding thickness can affect chamfering consistency by developing a mathematical model for regrinding cutters is discussed. Finally, simulation and experiment verify that the proposed gear chamfering method is feasible. The results provide both theoretical support for optimizing cylindrical gear chamfering processes and guidance for designing chamfering cutters.
