摘要

针对齿数大于41的直齿轮，基于切齿几何和齿轮啮合原理，明确渐开线齿廓起点和渐开线与基圆交点的区别，引入过渡曲线参数方程，对基于能量法的时变啮合刚度计算公式进行改进，全面建立了不同裂纹水平的故障轮齿模型。在此基础上，以斜线作为有效齿厚削减限制线，使得裂纹轮齿模型更严格、考虑因素更全面。参考有限元法计算结果，分别讨论了模型修正、裂纹程度、有效齿厚削减限制线具体形式等因素对时变啮合刚度的影响。计算结果表明，未修正轮齿模型会导致大齿数裂纹齿轮时变啮合刚度计算结果偏小；啮合刚度降低程度随裂纹水平的增大而不断增加。根据裂纹水平给出了有效齿厚削减限制线的建模建议：当裂纹水平较低时，有效齿厚削减限制线宜采用直线；当裂纹水平较高时，采用直线会产生较大误差；采用斜线不仅便于计算，同时能够满足计算精度需求，具有更强的实用性。

Abstract

For spur gears with more than 41 teeth

based on the geometry of cutting teeth and the principle of gear meshing

the difference between the starting point of the involute profile and the intersection of the involute and the base circle is clarified

and the transition curve parameter equation is introduced to calculate the time-varying meshing stiffness based on the energy method. The formula has been improved

and the faulty gear tooth models with different crack degrees are comprehensively established. On this basis

the oblique line is used as the effective tooth thickness reduction limit line

which makes the crack tooth model stricter and the considerations more comprehensive. With reference to the calculation results of the finite element method

the effects of model correction

crack extent

and the specific form of the effective tooth thickness reduction limit line on the time-varying meshing stiffness are discussed respectively. The calculation results show that the uncorrected gear tooth model will lead to a small calculation result of the time-varying meshing stiffness of gears with large numbers of teeth; the reduction degree of meshing stiffness increases with the increase of the crack level. According to the degree of cracks

the modeling suggestion for the effective tooth thickness reduction limit line is given: when the crack level is low

the effective tooth thickness reduction limit line should be a straight line; when the crack level is high

using a straight line will cause significant errors. Using a diagonal line is not only convenient for calculation

but also can meet the requirements of calculation accuracy and has stronger practicability.
