Prediction of Gear Performance based on Recognition of Tooth Contact Pattern

齿轮副的“齿面接触模式观察”实际上是齿轮车间和齿轮装置用户广泛采用的唯一方法，用于了解装置中的齿轮是否正确生产，或是否正确组装，或装置是否处于设计阶段预测的状态。有经验的齿轮工程师可以通过“齿面接触模式观察”来判断这些情况，但这种判断的所有依据都来自于他的经验，而这些经验不能被表达为其他工程师所理解的工程信息。即使是有经验的齿轮工程师也不能通过这种观察定量地预测这种齿轮的可靠性下降的程度或噪声和振动的状态。本研究开发了计算机程序，以定量预测齿轮性能作为函数的渐开线斜齿轮和准双曲面和锥齿轮的齿面接触模式。本研究将这种“齿面接触型态观察”的经验性“诀窍”技术，推广为有理论背景保证的工程方法。通过对齿面接触模式的观察识别，可以实现对应力状态和振动状态的定量预测。研究结果有助于提高齿轮减速器的可靠性、生产轻量化齿轮减速器和提高齿轮的寿命。

The "Observation of Tooth Contact Pattern" of gear pair is practically only one method incorporated widely in gearshop and by users of gear units to know, wether the gears in the unit are produced properly, or wether they are assembled properly, or wether the unit is in the state predicted at its design stage. The experienced gear engineer can decide these situation by the "Observation of Tooth Contact Pattern", but all the bases for such decision comes from his experience that cannot be expressed as the engineering information to be understood by other engineers. Even the experienced gear engineer can although not be able to predict the extent of the decrease of reliability or the state of noise and vibration of this gearing quantitatively by such observation. This research developed the computer program to predict the gear performance quantitatively as function to tooth contact pattern of involute helical gears and of hypoid and bevel gears. This research has generalized an empirical "Know How" technique of such "Observation of Tooth Contact Pattern" into the engineering method that is guaranteed by a theoretical back ground. This can realize the quantitative prediction of stress state and vibrational state by the observation of tooth contact pattern recognition. The results of this research contribute therefore to raise the reliability of gear units, to produce light weight gear unit and to
