一、前言与定轴齿轮传动比较,行星齿轮传动具有结构紧凑,传动比范围大,承载能力高,重量轻,体积小和效率高等明显优点。这些优点的最重要的根源是“动力分流”,因而实现各行星轮的载荷均匀分布(简称均载)是发扬行星齿轮传动优点的重要关键之一。均载方法很多,本文不研究静不定系统而仅研究静定系统的均载方法,因为前者如果依靠构件的高加工精度实现均载时,经济效果太 I. Introduction Compared with fixed-axis gear transmission, planetary gear transmission has the advantages of compact structure, large transmission ratio range, high carrying capacity, light weight, small size and high efficiency. The most important source of these advantages is “power split”, and thus achieving uniform distribution of the load on each planet (referred to as the average load) is to promote the advantages of planetary gear transmission is one of the key. There are many methods of load sharing. In this paper, we only study static equilibria system and load equalization method, because if the former relies on the high precision of the components to achieve load sharing, the economic effect is too
