摘要
当今，各种机械设备中，周转轮系用的愈来愈多，具有两个自由度的差动轮系也不例外，但其动力学分析尚无简单实用的现成公式。本文从多自由度机构的动力学观点出发，研究差动轮系各轮的广义坐标与对外力矩之间的关系，进而建立其运动微分方程，以便用来定量定性地分析各种差动轮系各中心轮的运动参数与动力参数之间的内在联系。
Nowadays, A epicyclic gear train is more and more nsed in the various mechanical devices, the came to a differential gear train containing two freedoms. But there aren' t ready-made simple and practical formulas for those dynamical analysis nutil now. This paper proceeded from dynamical standpoint of mechanism containing amny freedoms. Differential equation of motion was crcated after the relationchip between generalizcd coordinates and outer moment of all gears in a differential gear train was studied so that in ternal relation between parameter of motion and kinetic parameter of a central gear in a differential train was quailtatively and quantatively analyaed.
