Advantages of pulley drive: pulley drive can mitigate impact load; Pulley drive running stable, low noise, low vibration; The structure of pulley drive is simple, easy to adjust; Pulley drive for manufacturing and installation accuracy of pulley unlike meshing transmission strictly; Pulley drive has the function of overload protection; Two pulley drive shaft center distance adjustment range is larger. Belt drive faults: a pulley drive elastic sliding and sliding, transmission efficiency is low and can't maintain accurate transmission ratio; Pulley drive transmission of the same size of circumferential force, outline dimensions and axis pressure is greater than meshing transmission; The short life of pulley drive belt.
