一、综合法的任务由于行星传动具有结构紧凑、动力换挂、便于动力合成与分解、操纵轻便与便于实现自动操纵等一系列优点,随着科学技术水平的发展在国内外轿车、重型汽车、工程机械与装甲履带车辆中得到了日益广泛的应用。但是,目前较常用的二自由度行星传动机构行星排数目多,齿轮加工量大,高精度另件多,结构较复杂、成本高,不利于成批生产,尤其在实现较多的传动比工况时问题更为突 First, the task of comprehensive law As the planetary transmission has a compact structure, power for hanging, easy to power synthesis and decomposition, easy operation and easy to achieve automatic control and a series of advantages, with the development of science and technology at home and abroad cars, heavy vehicles, Construction machinery and armored crawler vehicles have been increasingly widely used. However, the more common planetary gears of the two-degree-of-freedom planetary transmission now have a large number of planetary rows, a large amount of gear processing, and a large number of high-precision components. The structure is complicated and the cost is high, which is not conducive to mass production. In particular, When the problem is more prominent
