Title:
MAGNETIC GEAR
Document Type and Number:
Japanese Patent JP2019168010
Kind Code:
A
Abstract:
To provide a magnetic gear capable of increasing transmittable possible torque.SOLUTION: A magnetic gear 10a comprises: an inner gear 14 having a plurality of inner magnets 14b aligned in the circumferential direction of an inner yoke 14a; a center ring 30 relatively-rotatably provided on the outer peripheral side of the inner gear 14 and having a plurality of pole pieces 30b aligned in the circumferential direction of a pole holder 30a; and an outer gear relatively-rotatably provided on the outer peripheral side of the center ring 30 and having a plurality of outer magnets 26b aligned in the circumferential direction of an outer yoke 26a. The outer magnet 26b is embedded in the outer yoke 26a so that adjacent same poles face each other in the circumferential direction. The outer yoke 26a has an outer magnet hole 26c in which the outer magnet 26b is embedded. The outer magnet hole 26c has an opening 26f on the inner peripheral surface of the outer yoke 26a.SELECTED DRAWING: Figure 3
