A pulley can be caused to rotate by creating longitudinal vibrations in a cord that passes over the pulley. For little amplitudes and high frequencies, the motion of the cord is certainly too small to notice and the pulley seems to be spinning with no cause, creating a striking effect. Pulley rotations were observed for a variety of pulleys and cords; almost any such system will work. The swiftness and path of the rotation depends upon the many physical parameters of the system: vibration frequency and amplitude, cord tension, and the radius and second of inertia of the pulley.
While welded pulley is welded and machined parts parts right 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 material. These pulleys possess high production efficiency. Not only 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 certainly well enjoyed in the high-end marketplace in the auto market, home appliances industry, machinery market ETC. We are haapy that you ask for our mature and professional spinning technology.
