PLANETARY MAGNETIC GEAR MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a planetary magnetic gear mechanism capable of transmitting larger rotation force when compared with a planetary magnetic gear mechanism in which each magnetic gear is magnetically connected by bringing side faces of the magnetic gears like circular column close mutually. SOLUTION: The planetary magnetic gear 2 constituting the planetary magnetic gear mechanism is provided with a spherical face. A sun magnetic gear 1 is provided with a curved face caused when an arc part of a semicircle having slightly larger radius than radius of the spherical planetary magnetic gear 2 is rotated toward an axis using a straight line which is parallel with chord of the semicircle as the axis. An inner magnetic gear 3 is provided with a curved face caused when a chord part of the semicircle is rotated toward the axis. COPYRIGHT: (C)2005,JPO&NCIPI
