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 motion of the cord is certainly too small to notice and the pulley appears to be spinning without cause, creating a impressive impact. Pulley rotations were observed for a variety of pulleys and cords; almost any such program will work. The quickness and direction of the rotation depends on the many physical parameters of the machine: vibration frequency and amplitude, cord tension, and the radius and second of inertia of the pulley.
While welded pulley is welded and machined parts pieces right into a whole, the machining and materials cost is high.
Spinning pulley adopted stamping and spinning technology, through the production process, it really is formed by extruding the whole part materials. 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. Now this pulley is definitely well enjoyed in the high-end marketplace in the auto sector, home appliances industry, machinery sector ETC. We are haapy that you demand our mature and professional spinning technology.
