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 definitely 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 program will work. The velocity and direction of the rotation depends on the many 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 items into a whole, the machining and material cost is high.
Spinning pulley used stamping and spinning technology, through the production process, it is formed simply by extruding the whole part materials. These pulleys have high production efficiency. Not only can it save raw materials and cost, but also can be used longer for its better wear-resisting and rust-proof. Right now this pulley can be well appreciated in the high-end market in the auto market, home appliances industry, machinery market ETC. We are haapy that you request our mature and professional spinning technology.
