Abstract

In the field of face gear tooth profile research, while the phenomena of undercutting and pointing are widely recognized, the occurrence of tooth top overcut is often overlooked. This paper employs the Normal to Tooth Profile Method (NTPM) to construct a mathematical model for the face gear tooth surface, encompassing the working surface, fillet surface, and top cutting surface. The tooth top overcut phenomenon is elucidated by means of tooth surface visualization and simulated gear cutting. The reliability of the proposed model is also compared with traditional models through the use of finite element simulations and tooth contact experiments. The study also analyzes the influence of design parameters on the amount of overcut and provides chamfering recommendations to eliminate it. The findings reveal that tooth top cutting is particularly significant in face gear pairs with high gear ratios, necessitating special attention when designing power-split transmission systems. Furthermore, the proposed NTPM is a more effective method for examining face gear tooth profile characteristics.

使用齿形法研究端面齿轮的顶部切削特征

在端面齿轮齿廓研究领域，虽然下切和尖削现象已得到广泛认可，但齿顶过切现象却经常被忽视。本文采用法向齿廓法（NTPM）构建了端面齿轮齿面的数学模型，包括工作面、圆角面和顶切面。通过齿面可视化和模拟齿轮切削，阐明了齿顶过切现象。此外，还通过有限元模拟和轮齿接触实验，将所提模型的可靠性与传统模型进行了比较。研究还分析了设计参数对过切量的影响，并提供了消除过切的倒角建议。研究结果表明，齿顶切削在具有高传动比的端面齿轮副中尤为明显，因此在设计功率分流传动系统时需要特别注意。此外，所提出的 NTPM 是检查端面齿轮齿廓特征的一种更有效的方法。
