IPC: F16D27/112
Filed: 1994-10-14
Abstract: PURPOSE: To provide an electromagnetic clutch having large transmission torque in the early period of the beginning of use and no possibility of adhesion. CONSTITUTION: An electromagnetic clutch 1 for transmitting intermittently the rotary power of an engine for traveling vehicle to a compressor of refrigerating cycle for the vehicle attaches an armature 5 to a rotor 4 with a magnetic force generated by an electromagnetic coil 3 to transmit the rotation of the rotor 4 to the armature 5. The friction surface 4a of the rotor 4 is coated with a coating material containing a main component of thermoplastic resin (epoxy resin). Thus, in the early period of the beginning of using the electromagnetic clutch 1 when the armature 5 is attached to the rotor 4, the coating material of the rotor 4 is deformed along with the delicate change in the shape of the rubbed friction surface 5a of the armature 5 and engages firmly the rubbed friction surface 5a. Also, the engagement is carried out between the metallic rubbed friction surface 5a and the coating material which are different from each other in the quality of material so that the generation of adhesion is prevented.
