Using this method, we can protract vector analysis atlas of planetary gear drive mechanism.
应用此方法，可定性地绘制出行星齿轮传动机构速度分析图谱。
We can understand clearly the components 'movement of planetary gear drive mechanism only by qualitative vector analysis.
仅通过定性速度分析便可清晰地了解行星齿轮传动机构中诸构件的运动形态。
The closed planetary gear drive mechanism can achieve a high transmission ratio and a high efficiency in transmitting large power with small volume, light weight and compacted structure.
闭式行星传动可在体积小、重量轻和结构紧凑的条件下实现大传动比，高效率地传递大动力。
