Ceramic tube silent rotor

Abstract

This utility model discloses a ceramic tube silent rotor, including a rotor frame and a magnetic ring sleeved on the rotor frame. The rotor frame has a shaft hole at its center for the rotor shaft to pass through. Multiple radially extending blades are evenly distributed along the circumference of one end of the rotor frame. The end of each blade away from the rotor frame has a tapered guide section for guiding fluid to flow smoothly along the blade surface. This utility model, by setting the tapered guide section, can guide the fluid to flow smoothly along the blade surface, reducing turbulence and thus lowering noise. Simultaneously, by setting a wear-resistant inner tube inside the shaft hole, the rotor's wear resistance is improved, extending its service life. Furthermore, the ceramic inner tube reduces friction noise, resulting in quiet and stable rotor operation.
