内啮合齿轮副加工误差状态下的强度分析

Strength Analysis of Inner Gear Pair with Machining Error

以内啮合齿轮副为研究对象,以Pro/E软件参数化建模为基础,建立了理想内啮合齿轮模型和误差内啮合齿轮模型,在ANSYS软件中分别对理想模型和误差模型进行了齿轮接触强度分析。通过对比分析表明,加入误差后,无论是哪种啮合齿轮,最大应力发生的部位和大小均有所变化。

In the paper, toke the straight tooth meshing spur gear as the research object and based on Pro/E software parametric modeling, ideal internal gear model and error model of the internal gear in ANSYS software was established re- spectively for gear contact strength analysis. Comparative analysis between ideal state and error state was presented and the conclusion was obtained. The analysis results showed that the maximum stress value and its location vary no matter what kind of mesh gear is concerned or not.
