Abstract
The invention provides an electromagnetic clutch that effectively reduces the shock noise produced during the coupling of an armature plate and a drive rotor, and furthermore, has a laminated body that can be provided at a low cost as an essential constituent element. The armature plate 34 of the electromagnetic clutch is a laminated body that comprises a plurality of thin metal plates 41, a plurality of fastening tongues 45 project from the inner diameter side of the friction plate 42 on the friction surface side, and these fastening tongues 45 are bent and surround the other laminated thin metal plates 41 so as to fasten them.
Claims6
An electromagnetic clutch comprising a drive rotor that is connected so as to communicate with a drive source and has a built in coil, and an armature positioned opposite to said drive rotor and having an armature plate disposed on the same rotation axis line, in which the end surfaces of said drive rotor and said armature plate are engaged or separated due to the magnetic force of said coil when said coil is energized by the application of voltage, and said drive rotor and said armature are intermittently coupled in communication;
- wherein said armature plate is a laminated body comprising a plurality of plates, wherein at least one of said plates comprising an end surface of said armature plate comprises a plurality of integrating elements protruding therefrom, said laminated body being integrated by said integrating elements, wherein at least one of said integrating elements protrudes from one of said plates which comprises a friction plate engageable with said drive rotor, and wherein said at least one of said integrating elements is bent so as to surround the other laminated plates such that they are fastened.
