众所周知,周转轮系由行星轮、中心轮(太阳轮)、转臂(系杆)及机架组成。在一般周转轮系中,转臂相对于机架作定轴转动,此时行星轮的轴线绕机架上的固定轴线回转。随着科学技术的不断发展,在生产实际中又出现一种具有双重行星轮(双重转臂)的周转轮系。该轮系以一般的周转轮系为基础,将其中某个行星轮作为另一个转臂以支承运动更为复杂的其它行星轮。由于这种周转轮系具有上述特点,所以我们称它为双重行星轮的周转轮系。一、应用在动参考系中的周转轮系1.周转轮系的组成大家知道,周转轮系可用作减速器、变速器和差速器;该轮系可把两个运动合成为一个运动,或将一
As we all know, the epicyclic train consists of a planetary wheel, a center wheel (sun gear), a revolving arm (tie rod) and a rack. In a conventional epicyclic gear train, the boom rotates in a fixed axis with respect to the frame, with the planet’s axis pivoting about a fixed axis on the frame. With the continuous development of science and technology, an epicyclic gear train with double planet wheels (double swing arm) appears again in production practice. The wheel train is based on a typical epicyclic gear train, using one of the planet gears as the other arm to support other planetary gears with more complicated motions. Due to the above characteristics of the epicyclic gear train, we call it the epicyclic gear train of a double planetary gear. First, the application in the dynamic reference system of the revolving wheel system 1. The composition of the revolving train As we all know, the revolving train can be used as a reducer, transmission and differential; the wheel train can be combined into a movement of two movements, Or one
