The advantages of belt pulley transmission are: belt pulley transmission can alleviate load impact; belt pulley transmission runs smoothly, with low noise and low vibration; belt pulley transmission has a simple structure and easy adjustment; belt pulley transmission is not as precise as mesh transmission for the manufacturing and installation accuracy of belt pulleys; pulley transmission It has the function of overload protection; the adjustment range of the center distance of the two shafts driven by the belt pulley is large.
The disadvantages of belt transmission are: pulley transmission has elastic sliding and slippage, low transmission efficiency and inability to maintain accurate transmission ratio; when pulley transmission transmits the same large circumferential force, the outline size and pressure on the shaft are larger than meshing transmission; pulley transmission belt, the belt life is shorter. The diameters and other dimensions of the pulleys of all kinds of mechanical equipment are all configured according to the reduction ratio, and designed according to the working speed and the speed of the motor.
