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 motion of the cord is certainly too small to note and the pulley appears to be spinning without cause, creating a impressive impact. Pulley rotations were observed for a variety of pulleys and cords; nearly any such system will work. The acceleration and path of the rotation depends upon the various physical parameters of the system: vibration frequency and amplitude, cord tension, and the radius and instant 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, during the production process, it is formed by extruding the complete part materials. These pulleys have high production efficiency. Not only can it save raw materials and price, but also can be used longer because of its better wear-resisting and rust-proof. Right now this pulley is certainly well enjoyed in the high-end market in the auto market, home appliances industry, machinery sector ETC. We are haapy that you demand our mature and professional spinning technology.
