汽车同步器齿套倒锥摆线旋分加工法研究

在阐述摆线旋分加工原理的基础上，提出用摆线逼近渐开线与旋分方法来加工汽车同步器齿套倒锥，并用摆线簇来提高逼近精度。建立了摆线的极坐标参数方程，推导出逼近误差的计算公式。在保证逼近误差限制在允许范围内的前提下，以加工效率最高为目标，提出了确定摆线参数的优化算法。应用自行开发的数控旋分加工机床对所提出的方法进行了实切验证，大量工艺实验表明，提出的工艺方法具有效率高、精度高、刀具简单、后续处理工艺简单等优点，具有很高的推广应用价值。

Research on the Cycloid Rotational Indexing Method for Machining the Back-angled Shifterstops in the Automobile Synchronizer Sleeves

The paper firstly described the machining principle of cycloid rotational indexing. Based on it, the method of using cycloid to approach involute was proposed to machine the back-- angled shifterstops in the automobile synchronizer sleeves. By building the cycloidal polar parameter equation, the approximate error formula was derived. To improve the approximate precision, cycloid cluster was used to approach involute. On condition that the approximate error was in allowable range, the optimization algorithm to fix cycloid parameters was given for the objective of the highest machining efficiency. The method proposed in the paper has been verified through a lot of machining experiments. As a result, the method has many advantages such as high efficiency, high precision, simple cutters and tips, simple post--processing and so on.
