A pulley can be caused to rotate by creating longitudinal vibrations in a cord that passes over the pulley. For small amplitudes and high frequencies, the movement of the cord is too small to notice and the pulley appears to be spinning without cause, creating a impressive impact. Pulley rotations were observed for a number of pulleys and cords; almost any such program will work. The quickness and path of the rotation depends on the many physical parameters of the system: vibration frequency and amplitude, cord pressure, and the radius and minute of inertia of the pulley.
While welded pulley is welded and machined parts parts into a whole, the machining and material cost is high.
Spinning pulley followed stamping and spinning technology, through the production process, it really is formed by extruding the complete part materials. These pulleys have high production efficiency. Not only can it save recycleables and cost, but also can be used longer because of its better wear-resisting and rust-proof. Right now this pulley is certainly well loved in the high-end marketplace in the auto sector, kitchen appliances industry, machinery market ETC. We are haapy that you ask for our mature and professional spinning technology.
