A pulley could 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 too small to notice and the pulley appears to be spinning without cause, creating a impressive effect. Pulley rotations were observed for a variety of pulleys and cords; nearly any such system will work. The quickness and path of the rotation depends upon the various physical parameters of the system: vibration frequency and amplitude, cord stress, and the radius and moment of inertia of the pulley.
While welded pulley is welded and machined parts pieces 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 have high production efficiency. Not merely can it save raw materials and price, but also can be used longer for its better wear-resisting and rust-proof. Now this pulley is usually well liked in the high-end marketplace in the auto industry, home appliances industry, machinery industry ETC. We are haapy that you demand our mature and professional spinning technology.
