ABSTRACT:
The electromagnetic coupling device 1 has a one piece armature hub (8) with a central bore attached to a compressor drive shaft (3). Flanges (8b) extend tangentially from the boss (8a) of the armature hub (8). The peripheral edges of the boss (8a) and the flanges (8b) are bent in an axial direction to form a peripheral wall (8c). A portion of the peripheral wall (8c) on the ends of the flanges (8b) form the chamber walls (8d) of damper covers (8e). The chamber walls (8d) have an opening on the side of the damper chamber facing the boss (8a). Rubber dampers (10) are compressed and mounted in each damper cover (8e). Torque pins (11) are mounted in the rubber dampers (10), pass out of the damper covers (8e) and are staked to the armature (12). Projections (8i) can be formed in the flanges (8b) by a press and limit movement of the armature (12) away from the rotor (6).
