What are the advantages and disadvantages of pulleys

这里是标题一h1占位文字

The advantages of the pulley drive are: the pulley drive can alleviate the load impact; the pulley drive runs smoothly, with low noise and low vibration; the pulley drive has a simple structure and is easy to adjust; the pulley drive is not as strict as the manufacturing and installation accuracy of the pulley; It has the function of overload protection; the adjustment range of the center distance between the two axles driven by the pulley is large. The disadvantages of the belt drive are: the pulley drive has elastic sliding and slipping, the transmission efficiency is low and the accurate transmission ratio cannot be maintained; when the pulley drive transmits the same large circumferential force, the contour size and the pressure on the shaft are larger than the meshing drive; the pulley drive belt shorter lifespan.
