| 摘 要： | 以平行轴变齿厚斜齿轮传动为研究对象，根据齿轮啮合原理及小、大齿轮的齿面方程，分别建立其标准安装以及存在中心距安装误差、轴线安装误差和综合安装误差时轮齿接触的数学模型，通过Matlab编程进行求解，得到不同安装情况下轮齿的接触轨迹及传动误差并进行了对比分析。结果表明，该齿轮传动对轴线安装误差较敏感，形成了边缘接触并且引起周期性的传动误差 为该齿轮传动的设计与分析奠定了基础。

| Abstract: | The study object of this paper is helical beveloid gears with parallel axis. Based on the gear Mshing Principles and the tooth-surface equations of pinion and gear,the mathematical model of tooth contact is developed under standard installation and installations with center distance error,axis error and multiple error respectively. The MATLAB solver is used to obtain the contact trace and the transmission error under different installing conditions and the comparative analysis is made. The results indicate that this gear drive is sensitive to axis installation errors,it forms the edge contact and cause the periodic transmission error. It can provide the foundation for designs and analysis of this gear transmission. |
