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 note and the pulley seems to be spinning without cause, creating a striking effect. Pulley rotations were observed for a number of pulleys and cords; nearly any such system will work. The rate and path of the rotation depends upon the various physical parameters of the machine: vibration frequency and amplitude, cord tension, and the radius and moment of inertia of the pulley.
Welded pulley:
While welded pulley is welded and machined parts parts into a whole, the machining and material cost is high.

Spinning pulley:
Spinning pulley adopted stamping and spinning technology, during the production process, it really is formed simply by extruding the whole part materials. These pulleys have high production efficiency. Not merely can it save recycleables and cost, but also can be used longer for its better wear-resisting and rust-proof. Today this pulley is certainly well liked in the high-end market in the auto market, kitchen appliances industry, machinery market ETC. We are haapy that you demand our mature and professional spinning technology.
