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 appears to be spinning with no cause, creating a impressive impact. Pulley rotations were observed for a variety of pulleys and cords; nearly any such system will work. The velocity and direction of the rotation depends on the many physical parameters of the system: vibration frequency and amplitude, cord pressure, and the radius and minute of inertia of the pulley.
While welded pulley is welded and machined parts parts into a whole, the machining and material cost is high.
Spinning pulley adopted stamping and spinning technology, through the production process, it is formed simply by extruding the complete part materials. These pulleys possess high production efficiency. Not only can it save recycleables and price, but also can be used longer because of its better wear-resisting and rust-proof. Now this pulley is usually well enjoyed in the high-end market in the auto sector, kitchen appliances industry, machinery industry ETC.
