Spinning pulley

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 motion of the cord is definitely too small to notice and the pulley seems to be spinning with no 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 upon the various physical parameters of the machine: vibration frequency and amplitude, cord tension, and the radius and instant of inertia of the pulley.
Welded pulley:
While welded pulley is welded and machined parts pieces into a whole, the machining and materials cost is high.

Spinning pulley:
Spinning pulley adopted stamping and spinning technology, during the production process, it is formed simply by extruding the whole part material. These pulleys have high production efficiency. Not only can it save recycleables and price, but also can be utilized longer because of its better wear-resisting and rust-proof.
