Abstract: PROBLEM TO BE SOLVED: To avoid malfunction of a torque limiter part which is caused by a weight member fitted to a cylindrical member on driven side. SOLUTION: There are provided a pulley 11 which rotates upon receiving torque from a drive source, a cylindrical member 19 which rotates together with a spindle 17 while connected to the spindle 17 of compressor 15, a torque limiter part 20 which, provided on the torque transmission path from the pulley 11 to the cylindrical member 19, shuts off transmission of the torque when the transmission torque reaches a prescribed value, and a weight member 22 which, provided to the cylindrical member 19, acts as an inertia mass. The weight member 22 is fixed by press-fitting to the cylindrical member 19 at such part closer to the spindle 17 side than to the torque limiter part 20. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a power transmission device wherein the misassembly or missing of a portion of a rubber damper 9 is prevented and the fall-off is prevented when disassembled. SOLUTION: First, the rubber damper 9 is held on an output disc 8. Thereby, the fall-off of the rubber damper 9 is prevented when disassembled and the missing due to the fall-off is also prevented. Lock portions 9a, 23a are formed on a pin portion 23 and a corresponding portion of the rubber damper 9. Both latch portions 9a, 23a are locked to each other to hold the rubber damper 9 on the output disc 8. In this specific holding method, the latch portions 9a, 23a are provided where a latching shape can be added relatively easier even if the rubber damper 9 has a complicated shape. Both latch portions 9a, 23a are asymmetrical in the circumferential direction of the pin portion 23. Thus, when the rubber damper 9 is assembled, an directional error gives no locking feel to prevent the misassembly. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a power transmission device for rapidly and surely cutting of the transmission of an overload torque. SOLUTION: A gear part 7 serving as a torque limiter is coupled to a rotary member 5 which is rotated, integral with a pulley 3, so as to be axially movable in a rotationally limited condition, and is threadedly coupled to a hub 6 fixed to a shaft of a compressor, by a predetermined fastening torque. It is noted that the threaded coupling between the gear part 7 and the hub 6 is constituted in such a way that the fastening torque is decreased (loosened) by rotating the gear part 7 in the rotational direction of the pulley 3, relative to the hub 6. Thus, the compressor is locked so as to increase the load torque of the shaft 2 side. When the load torque becomes higher than the fastening torque of the gear part 7, the gear part 7 is rotated in the loosening direction, relative to the hub 6. As a result, the gear part 7 is axially moved while it is rotated integral with the rotary member 5, and accordingly, the threaded coupling with the hub 6 is released. Thus, the power transmission between the hub 6 and the rotary member 5 is cut off.

Abstract: PROBLEM TO BE SOLVED: To provide a connector integrated stator for electromagnetic clutch in which a fusing part of a coil terminal wire with a terminal is not affected by the difference in the coefficient of thermal expansion between a metallic housing and a resin coupler, and the breakage of the coil terminal wire can be prevented. SOLUTION: A fusing part 39 of a coil terminal wire 26 of an electromagnetic coil 21 with a terminal 31 of a connector 23 is located inside a coupler 33 to avoid a boundary part of a metallic housing 22 and the resin coupler 33. In addition, the fusing part 39 is located at the position so that a round bending part 32 on a base end side is larger than the fusing part 39. Even when the fusing part is affected by the difference in the coefficient of thermal expansion between the housing 22 and the coupler 33, the stress is exerted in the direction where the round bending part 32 of the coil terminal wire 26 is deflected, and the stress concentration to the round bending part 32 of the coil terminal wire 26 can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic clutch capable of keeping a proper value of a gap between an armature and a rotor by preventing abrasion of a cover. SOLUTION: A plate member 19 is interposed between a cup part 18 for supporting a rubber hub 16 and a cover 13 bonded to the end surface of an armature 5 on the opposite side to a rotor. This plate member 19 is formed of the same material (for instant, iron) as a hub plate provided with the cup part 18, the front surface is formed into a circular ring body, and the side surface is formed into a low stepped shape. In this plate member, a ring-shaped part on the outside diameter side from the stepped part is overlapped on the front surface of the cover 13 in a state where the ring-shaped part on the inside diameter side from the stepped part is inserted in the inner periphery of a round hole formed on the cover 13, and the ring-shaped part on the inside diameter side from the stepped part is caulked to the armature 5 by a rivet 11 and integrally fixed to the armature 5.

Abstract: PROBLEM TO BE SOLVED: To reduce noise by restraining vibration of an output disc 8 being a sound generating source.
SOLUTION: An outer diameter ΦA of an inner hub 22 is formed larger than an inner diameter ΦP of a pin part 23. Rigidity of the output disc 8 is enhanced by enlarging the outer diameter ΦA of the metallic inner hub 22 up to a part of the resin pin part 23. This constitution can reduce the noise in the vicinity of 1.5 to 2 KHz conventionally generated when turning off a refrigerant compressor being a rotary device by restraining the vibration of the output disc 8. A characteristic of this structure can reduce the noise only by changing the output disc 8 without enlarging the output disc 8 and changing the other part. A torque (rotational) variation by compression work of the refrigerant compressor can be reduced by increasing inertial weight of the inner hub 22.

Abstract: PROBLEM TO BE SOLVED: To sufficiently absorb a variation of torque without causing a large size of a coupling. SOLUTION: The power transmission device is made to Neidhart structure such that a damper 140 is shearing-deformed while compression-deformed when a torque is applied to a pulley 110. Thereby, since an elastic coefficient of the damper can be made small as compared with the application in which the variation of torque is mainly absorbed only by compressive deformation, the variation of the torque can be sufficiently absorbed without causing a large size of the coupling 100. In this connection, the torque is transmitted by reaction force generated accompanying with deformation of a component in a rotation direction of the deformation of the damper 140 (compressive deformation and shearing-sdeformation). The variation of the torque is absorbed by the deformation (compressive deformation and shearing deformation) of the damper 140. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To shorten the armature detachment time when a clutch is turned off while ensuring the effect to reduce the armature working noise when the clutch is turned on. SOLUTION: Armatures 5 (5a, 5b) to be attracted to a rotor by the electromagnetic force generated by an electromagnetic coil 3 are connected to a hub to be connected to a driven side equipment by a leaf spring, and an elastic material 18 to be elastically compressed along with the elastic deformation of the leaf spring when the armatures 5 are attracted to the rotor. The elastic material 18 is of the shape to be arranged on an inner circumferential side of the armatures 5, and a press-fit contact part 18d to be press-fitted to the inner circumferential surface of the armatures 5 and a non-contact part 18e separated from the inner circumferential surface of the armatures 5 are formed on an outer circumferential surface of a fan-like part 18a of the elastic material 18.
