Spinning pulley

A pulley could 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 usually too small to note and the pulley seems to be spinning with no cause, creating a striking effect. Pulley rotations were observed for a number of pulleys and cords; nearly any such system will work. The rate and path of the rotation depends on the various physical parameters of the system: vibration frequency and amplitude, cord stress, and the radius and moment of inertia of the pulley.
Welded pulley:
While welded pulley is welded and machined parts items into a whole, the machining and material cost is high.

Spinning pulley:
Spinning pulley used stamping and spinning technology, during the production process, it is formed by extruding the complete part material. These pulleys have high production efficiency.
