主动带轮 meaning in Chinese

driving pulley

This phenomenon makes the circumferential velocity of the driven wheel be slower than the drive wheel ' s decrease the efficiency of the belt drive abrade the belt and shorten its life . so , it is very important for those who design and use it to know and understand qualitatively and quantitatively the phenomenon of elastic slippage
弹性滑动的存在使从动带轮上的圆周速度低于主动带轮上的圆周速度，带传动效率降低，带磨损和工作寿命缩短，因此，定性和定量地认识和理解带传动中的弹性滑动现象对于带传动的设计和使用是十分重要的。
