摘　　要：转换机架法是机构创新的重要方法,在轮系的创新设计中有重要应用前景。文中以最简单的轮系为创新基础,探讨机架变换后的新轮系与原轮系的传动比关系,得出重要结论:以轮系系杆为输出构件时的传动比与系杆固定时机构的传动比之和为1。然后对该结论进行证明,再通过典型的行星轮系、少齿差传动、平动齿轮传动和复杂的混合轮系的机架变换进行传动比的计算,验证了该结论的正确性。最后阐明了该结论在复杂行星轮系传动比计算中的重要作用。The frame alternation method is an important method of mechanism innovation;it has significant application prospects in the innovative design of gear train.Taking the simplest gear train as the innovative base,this paper probed into the transmission ratio relationship between the new gear train after the alternation of frame and the original gear train,thus an important conclusion was educed that the sum of the transmission ratio that takes the gear train linking bar as the output component and the transmission ratio of the mechanism when the linking bar was fixed equals to one. And then a certification was carried out on this conclusion. By means of car- rying out the calculations of transmission ratios on the typical planetary gear train, the fewer teeth differenced transmission, the translational gear transmission and the frame alternation of complex hybrid gear train, the correctness of this conclusion was verified. Finally the important role of this conclusion in the calculation of transmission ratio of the complex planetary gear train was clarified.
