  • Electromagnetic clutch with improved guidance and retention
    Patent number: 5390774
    Abstract: An electromagnetic air conditioning compressor clutch of the type that mounts the armature through an elastomeric pad. The flexibility of the pad can lead to undesired radial whirl of the armature about the shaft of the compressor, which is compensated for without affecting the flexibility of the pad. The armature is fixed to the outer edge of the pad by an outer ring which has an axially extending, cylindrical sleeve. A guide plate fixed to the compressor shaft has a cylindrical guide flange that axially overlaps the outer ring sleeve, closely, but slidably. The ring, and the armature, can therefore move axially as the pad is flexed, but are guided radially and circumferentially.
