摘要： 闭式齿轮传动中的齿面疲劳磨损机制类似于剥层磨损机制,由此建立了齿面啮合摩擦疲劳磨损计算的数学模型.磨损层厚度的表达式中,涉及磨损率、每啮合一次轮齿的滑动距离、工作转速、工作时间、相啮合齿轮副数以及齿面改性系数、润滑系数、载荷系数等参数.给出了计算模型中各参数的确定方法,讨论了计算模型的适用场合.通过反映齿面磨损物理过程规律的数学模型,寻找不同工况下减小齿面啮合疲劳磨损的途径;该模型具有工程实际意义,为齿轮啮合磨损过程的计算机仿真提供了依据.

Abstract: The process of fatigue wear-off of tooth face in a closed gear drive system is similar to a layered wear-off mechanism. A mathematical model is thus developed to calculate the friction-fatigue wear-off of tooth face in gearing. The wear rate, teeth slippage during each meshing engagement, rotational speed, time for gearing, number of gear pairs in meshing process and the coefficients of teeth face modification, lubrication and loading are all involved in the expression of worn layer thickness. With the methods given to determine all of the parameters required for the calculation model, what the model is applicable to are discussed. The ways to reduce the fatigue wear-off due to meshing teeth faces under different working conditions are found out via the mathematical model describing the physical process of tooth face wear-off. The model proposed is of technological importance to engineering practice and available to provide reference for simulation of wear-off process of gear engagement.
