However, because of the differences of the transmission ratio and speed, the author enlarges the planet gear, solar gear, thickness of the inner circle ring as well as the enclasping radius of the enclasping brake through the mechanical design and calculation.

在设计过程没有改变原有的升降机零部件的位置关系，但由于，传动比以及传动速度的不同，所以，通过受力分析计算，加大了行星齿轮、中心齿轮、内齿圈的厚度；同时也加大了抱闸抱紧时的抱紧半径。

In this article , instead of changing the ubiety among the parts of the original elevator , the author keeps on using the original structure. However, because of the differences of the transmission ratio and speed, the author enlarges the planet gear, solar gear , thickness of the inner circle ring as well as the enclasping radius of the enclasping brake through the mechanical design and calculation .
