A pulley can be caused to rotate by creating longitudinal vibrations in a cord that passes over the pulley. For small amplitudes and high frequencies, the movement of the cord is definitely 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 swiftness and direction of the rotation depends on the many physical parameters of the system: 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 pieces into a whole, the machining and materials cost is high.
