摘要
因强度不足而使齿轮磨损失效是风力发电机组增速箱中渐开线斜齿内齿轮啮合传动中常见的问题。遵循接触疲劳强度有限元分析基本流程,利用Pro/E建立斜齿内齿轮的三维立体模型并导入ANSYS分析软件中。通过对齿轮对进行接触非线性有限元分析,获得接触应力云图并判断斜齿内齿轮啮合瞬间最大应力发生的轮齿部位,确定最大应力值,并与传统齿轮强度计算方法计算出的结果进行比较,为齿轮的设计提供了理论依据,为日后风机的设计奠定坚实的基础。
Gear failure because of the strength deficiency is a very common problem in the involute helical internal gears engaging which is used in gear box of the wind motor. Based on the contact finite element analytic process, the helical internal gears＇ 3D stereoscopic model is established by Pro/E and lead into the ANSYS analytic software. After non-liner contact finite element analytic is performed, the nephograms of the contact stress is obtained and the maximum stress position of the helical internal gears is determined. The maximum stress position is compared with the traditional gear strength calculation results to provide a basis if the design gear is reasonable and lay a solid foundation of the wind motor in the future.
