Abstract

The present invention aims to provide an electromagnetic clutch capable of decreasing the impact noise generated when the armature plate and the driving rotor are coupled. An electromagnetic clutch in the present invention comprises a driving rotor including a coil, and an armature having an armature plate that is disposed facing this driving rotor and having the same axis of rotational thereas, and when a voltage is applied to excite coil, the end face of driving rotor and the armature plate are attached together by coil's magnetic force, thereby coupling driving rotor and armature. Armature plate comprises a plurality of metal thin plates (plate members) laminated together, and at least a part of the plate members being connected each other.

Description

technical field [0001] The invention relates to an electromagnetic clutch, in particular to an electromagnetic clutch used for an automobile air-conditioning compressor. Background of the invention [0002] Figure 16 It is a longitudinal section view of an ordinary electromagnetic clutch. [0003] The electromagnetic clutch 100 is installed in an automobile air conditioner compressor. The electromagnetic clutch 100 is intermittently mechanically connected to the compressor and an unillustrated drive source. The electromagnetic clutch 100 is provided at the front end 101 of the compressor front casing. [0004] The driving rotor 103 is rotatably supported on the outer peripheral surface of the front end 101 via the clutch bearing 102 . The coil 104 is provided inside the drive rotor 103 . The armature disk 105 is arranged coaxially facing the drive rotor 103 . [0005] The hub 106 is secured to an extension of the compressor drive shaft 112 by a nut 107 . One end of th...
