<P>PROBLEM TO BE SOLVED: To provide a magnetic gear device that prevents an increase in temperature of components during transmission of torque. <P>SOLUTION: The magnetic gear device includes: an input magnetic gear 2 formed by arranging a plurality of magnets 24 in a circumferential direction on a magnetic force generating surface that is provided radially outward around an axial line of an input rotating shaft 1; an output magnetic gear 3 which concentrically encircles the input magnetic gear 2, and is formed by arranging a plurality of magnets in a circumferential direction on a magnetic force generating surface facing the magnetic force generating surface of the input magnetic gear 2; and a magnetic path member 4 formed of a magnetic steel and fixed between magnetic force generating surfaces of the input magnetic gear and the output magnetic gear 3 which are facing each other, while being arranged in a circumferential direction so as to be interposed between magnetic poles of the input magnetic gear 2 and the output magnetic gear 3. A cooling medium flowing path 45 is formed between a plurality of magnetic path members 41 of a magnetic path member holder 41 for fixing the magnetic path member 4 to guide the air discharged toward the magnetic force generating surface. <P>COPYRIGHT: (C)2013,JPO&INPIT |
