一、前言行星齿轮传动均载方法很多,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,经济效果太差;如果依靠弹性件实现均载时,由于材料的弹性与承载能力之间的制约关系,均载效果又欠佳。本文提出的构件调位法属于均载的静定系统,其基本原理是为构件提供附加的自由度,当不均载时构件根据受力的不同在附加自由度的范围内相应地调节位置(调位)以实现均载。
I. INTRODUCTION There are many methods for equalizing planetary gear transmissions. This paper does not study the statically indeterminate system but only the method of uniform loading for statically determinate systems, because if the former relies on the high machining accuracy of components to realize uniform loading, the economic effect is too poor; When the parts are evenly loaded, due to the constraints between the elasticity of the material and the carrying capacity, the load sharing effect is not good. The component alignment method proposed in this paper belongs to the statically-determined system. The basic principle is to provide additional degrees of freedom for the components. When there is uneven loading, the components are adjusted accordingly in the range of additional degrees of freedom according to different forces ( Adjustment) to achieve uniform loading.
