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 motion of the cord is definitely too small to notice and the pulley seems to be spinning without cause, creating a striking effect. Pulley rotations were noticed for a variety of pulleys and cords; nearly any such system will work. The rate and direction of the rotation depends on the many physical parameters of the system: vibration frequency and amplitude, cord stress, and the radius and second of inertia of the pulley.
While welded pulley is welded and machined parts pieces into a whole, the machining and materials cost is high.
Spinning pulley followed stamping and spinning technology, during the production process, it really is formed by extruding the whole part material. These pulleys possess high production efficiency. Not merely can it save recycleables and cost, but also can be used longer because of its better wear-resisting and rust-proof. Today this pulley can be well enjoyed in the high-end marketplace in the auto sector, home appliances industry, machinery market ETC.
