ABSTRACT:
An electromagnetic spring-wound clutch for a refrigerant compressor includes a coil-wound spring disposed around a pulley and having one end connected to an armature plate and cover plate. The cover plate is connected to a hub which is fixed on the outer end of the drive shaft of the refrigerant compressor through an elastic member. The elastic member is closely fitted in a polygonal-shaped air gap defined between the cover plate and hub. As a result, the impact force generated when the coil-wound spring is wound around the pulley during transmission of rotating motion is absorbed by the elastic member instead of the hub and drive shaft of the refrigerant compressor to thereby increase the life and durability of both the electromagnetic clutch and the refrigerant compressor.
