摘要： A coupling device has a pulley that receives rotational torque from an engine. The torque is transmitted to a shaft through a hub and a one-way clutch. A torque limiter is screwed on the shaft to fasten the inner ring of the one-way clutch onto the shaft. The torque limiter has a breakable portion. The torque is directly transmitted from the inner ring to the shaft when the torque is normal. If the torque exceeds the tightening torque of the torque limiter, the inner ring begins to slide and rotate, and drives the torque limiter in a tightening direction. As the torque limiter is tightened additionally, the tensile stress on the breakable portion is increased. Then, the breakable portion breaks and is separated in axial direction so that the coupling device disconnects torque transmission.

摘要： An electromagnetic clutch has an electromagnetic coil and a coil housing for accommodating the coil. The coil is inserted into the coil housing together with insulating members made of readily deformable insulating material. The insulating members are pressed downwardly by the coil and deformed according to an inner shape of the coil housing. As a result, the coil and the insulating members are accommodated in the coil housing with a preset gap between a surface of the coil and an inside surface of the coil housing, formed by the insulating members. The gap is filled with melted resin so that the coil is firmly secured in the coil housing. Thus, the coil can be readily secured in and insulated from the coil housing at a low cost.

摘要： A clutch mechanism includes a pulley, an armature, an electromagnet, a plate spring and a damper. The armature combines with the pulley in a direction of a rotation axis. The electromagnet generates attracting magnetic force, which attracts the armature in a joining direction. The plate spring generates resilient force, which urges the armature in an opposite direction from the joining direction. The damper includes an impact mitigation part mitigating an impact when the armature collides with the pulley. The pulley, the armature, the damper and the plate spring are arranged in this order in the direction of the rotation axis. The damper includes a contact portion contacting part of the armature in the direction of the rotation axis. The plate spring includes a pressing part pressing the contact portion on the armature during both the joining and unjoining of the armature and the pulley.

摘要： In a torque transmission system, plural engagement pieces elastically deformable are formed integrally with an outer peripheral portion of a circular portion of a center hub to be engaged with an inner periphery portion of a pulley. A bridge portion of the center hub is disposed to be broken when a torque large than a predetermined torque is applied there to. Since the engagement protrusion pieces are engaged with a part of the pulley, it can prevent the center hub from being removed and falling when the bridge portion of the center hub is broken.

摘要： An electromagnetic clutch has an armature, a rotor housing accommodating a stator housing and an exciting coil having negative and positive terminals. A passage is formed to extend from an outer peripheral surface of the stator housing to the negative terminal and the positive terminal. The passage is filled with a conductive metal member having a melting point lower than that of the stator housing between the outer surface of the stator housing and the negative terminal. When frictional heat generated between the armature and the rotor housing exceeds a preset value, the metal member melts and flows to the positive terminal, thereby short-circuiting the coil. As a result, a fuse between a power source and the clutch is fused, thereby turning off the clutch. Therefore, the clutch does not need to have a thermal fuse therein and is reduced in size without increasing power consumption.

摘要： An electromagnetic clutch for a compressor in an air conditioning system, having a rotor 2 for receiving a rotating movement from its source, a hub 12 in connection with a rotating shaft of the compressor, a coil housing 4 for storing a coil spool 14 on which an electromagnetic coil is wound, and an armature 8 which is attracted to a frictional surface 2a of the rotor 2 under the effect of an electromagnetic attracting force generated by the electromagnetic coil 5. The coil spool 14 has an inclined surface at an inner corner location which is located adjacent the frictional surface 2a of the rotor 2. The coil spool has a recess at a location where the inclined surface is formed, in which recess a temperature fuse is arranged. The temperature fuse is broken under a condition that the temperature is higher than a predetermined value, thereby de-energizing the electromagnetic coil 5.

摘要： A magnetic clutch includes a rotor and an armature facing to each other for establishing a coupling connection. A serpentine magnetic circuit is formed in the rotor and the armature. A method for manufacturing a rotor of a magnetic clutch of the invention comprises the step of deforming a single ring-shaped plate of a magnetic material, by a plastic deformation process such as cold forging, into a ring-shaped element comprising generally concentric inner and outer cylindrical walls, and a ring-shaped bottom wall. Prior to or after or simultaneously with this step, ring grooves are formed on the bottom wall. A nonmagnetic material is then filled in the ring grooves, and the bottom surface of the bottom wall is cut to form a friction surface. By this cutting, the nonmagnetic material is exposed at the friction surface.

摘要： An electromagnetic clutch capable of reducing a noise generated upon contact of an armature with rotor. Connecting member 20 for connecting inner and outer rings 5a and 5b of the armature are integrally formed with arms 19 extending radially inwardly from locations where the connection members 20 are connected to the inner ring 5a by rivets 12. The arms 17 are in face to face contact with an elastic member 18 made of rubber, which is held by the inner hub 7 by means of a retainer 19. Upon the movement of the armature 5 toward to rotor 4 by means of an electromagnetic force, just before the contact of the armature 5 with the rotor 4, a steep increase in a force for opposing the movement of the armature 5 with respect to the rotor 4 is obtained, thereby reducing an impact upon the contact, and reducing the noise.
