Abstract

Lapping is a complex precision tooth surface cutting technology for the extended epicycloid hypoid gears, which relies on experienced engineers to obtain ideal machining quality by setting the process parameters reasonably and accurately controlling cutting process. In order to improve the predictability and controllability, influence of different gear parameters on lapping process and geometric topography was systematically studied. Focusing on tooth surface lapping and its micro-topography, an innovative prediction method id proposed. Firstly, the hypoid gear pair model is established, and then height parameters of the tooth surface are calculated by the deduced lapping depth formula. Then, a local tooth surface was reconstructed based on the height parameters by using fast Fourier transform, and prediction model of micro-topography considering the initial topography and random wear mechanism was established. Finally, different lapping parameters considering cutting characteristics of abrasive particles is designed for their influence on tooth surface micro-topography.

扩展摆线准双曲面齿轮研磨齿面微形貌预测

精磨是一项复杂的大摆线准双曲面齿轮精密齿面切削技术，需要经验丰富的工程师通过合理设定工艺参数，精确控制切削过程，才能获得理想的加工质量。为了提高可预见性和可控性，系统研究了不同齿轮参数对研磨过程和几何形貌的影响。针对齿面研磨及其微形貌，提出了一种创新的预测方法。首先建立准双曲面齿轮副模型，然后利用推导出的研磨深度公式计算齿面高度参数。然后，利用快速傅立叶变换基于高度参数重构局部齿面，建立考虑初始形貌和随机磨损机理的微形貌预测模型；最后，考虑磨粒切削特性，设计不同研磨参数对齿面微形貌的影响。
