MAGNETIC GEAR DEVICE

摘要

PURPOSE: A magnetic-gear combination is provided to be cost-effectively manufactured using a plastic assembling screw and a snap ring in order to prevent the escape of a magnetic gear. CONSTITUTION: A rotary shaft(10) includes a first directional male screw and a second directional male screw. The first directional male screw is formed on the outer circumference of the end of the rotary shaft. The second directional screw rotates to the opposite direction of the rotating direction of the first directional male screw. A magnetic-gear(20) includes a rotary shaft installing hole(23) and a second directional female screw(22). The rotary shaft installing hole is formed on the center of the magnetic-gear. The rotary shaft passes through the rotary shaft installing hole. The second directional female screw is combined with the second directional male screw. An assembling screw fixes the magnetic-gear to the rotary shaft.
