ABSTRACT:
An electromagnetic clutch 10 for transmitting torque includes a field coil assembly 16, a rotor assembly 18 and an armature assembly 20. The field coil assembly 16 includes a toroidal electromagnetic coil 22. The rotor assembly includes a tubular portion 42 mounted on a bearing 36, a ring-shaped section 52 with an attraction surface 54, an outer drum-shaped flange 56 and a drive ring 60. The armature assembly 20 includes an armature hub 62, rubber stops 70, ring-shaped armature 74 and spring steel connecting members 72 connecting the armature to the armature hub. The armature hub 62 includes a central hub 64 with a bore 66 and a stopper plate 68. The bore 66 receives a splined shaft 14 and an air gap adjustment screw 88. A shaft contact surface 94 on the air gap adjustment screw 88 contacts the forward end 96 of a splined shaft 14. The position of the armature hub 62 on the splined shaft 14 and of the armature 74 relative to the attraction surface 54 is changed by rotating the air gap adjustment screw 88 relative to the central hub 64. A plate 106 locks the air gap adjustment screw 88 relative to the central hub 64. A bolt 101 secures the armature assembly 20 to the splined shaft. The armature assembly 20 can be removed from the splined shaft 14 by removing the bolt 101 and screwing a larger bolt into the threaded bore 102.
