Abstract
PURPOSE: To perform a switching operation of the coupling action of two pulleys in the clutch with a simple handling, by placing an armature rotated as an integral unit with each of the two pulleys rotatably supported respectively to a shaft engage- disengage capably in a face-to-face relation with a rotor mounted to the same shaft.
CONSTITUTION: To operate the clutch, firstly a belt is put into V-grooves of pulleys 8, 11. A magnetic flux of a permanent magnet 10 is activated in such an order as to flow in through the permanent magnet 10, an inner portion of the pulley 11 from a hole 22, an armature 17, an outer portion of the pulley 11 from the hole 22, the outer circumferential, side and inner circumferential parts of a yoke 12 and a housing 9 returning to the permanent magnet 10. Here a coil 14, if applied a voltage of one polarity and energized, for instance, when its applied magnetic flux is in the same direction as the magnetic flux of the permanent magnet 10, increases the force of attracting the armature 17 toward a side of the pulley 11 causing the armature 17 to be moved rightward against a leaf spring 16 finally to be attached to a side of the pulley 11. In this way, the pulley 11 and the rotary shaft 1 can be coupled.
