A pulley can be caused to rotate by creating longitudinal vibrations in a cord that passes over the pulley. For little amplitudes and high frequencies, the movement of the cord is certainly too small to note and the pulley seems to be spinning with no cause, creating a impressive impact. Pulley rotations were observed for a number of pulleys and cords; almost any such program will work. The quickness and direction of the rotation depends upon the various physical parameters of the machine: vibration frequency and amplitude, cord pressure, and the radius and moment of inertia of the pulley.
Welded pulley:
While welded pulley is welded and machined parts parts right into a whole, the machining and material cost is high.
Spinning pulley:
Spinning pulley used stamping and spinning technology, through the production process, it is formed simply by extruding the complete part materials. These pulleys have high production efficiency.
