Electromagnetic clutch

Abstract

Abstract PURPOSE:To aim at simplifying part forms and facilitating manufacture by constructing such that a magnetic path is formed inside a yoke when a coil is electrified and a rotor becomes a single magnetic pole. CONSTITUTION:When the rotational force is transmitted to a gear 17, an armature hub 16 and an armature 19 are rotated together with the gear 17. In this case, when a coil 20 is electrified, yokes 22a, 22b are magnetized, the right end part 15a of a rotor 15 acts as a magnetic pole, and a magnetic path phithrough yoke 22a right end part 15a of rotor 15 armature 19 yoke 22b yoke 22a is formed. As a result, the magnetic attraction force acts between the rotor 15 and the armature 19, and the armature 19, sliding on the arm 16a of the armature hub 16, is adhered to the rotor 15. Accompanied by this, the rotor 15 and the rotor hub 13 are rotated. Torque can be thus transmitted to an output shaft 14 through a rotor hub 13.
