Abstract: PROBLEM TO BE SOLVED: To transmit large torque while sufficiently absorbing a torque fluctuation. SOLUTION: In a damper 14 of this torque transmission device, a first elastic modulus k1 (=ΔT/Δθ) of a first deformation part 14a applied with torque in a normal rotation direction is set to be larger than a second elastic modulus k2 of a second deformation part 14a applied with torque in a reverse rotation direction. Thereby, even if a compressor 1 operates to cause enlarging of necessary torque, the large torque is transmitted with preventing the damper 14 from exceeding an elastic limit, and the torque fluctuation can be sufficiently absorbed. When a discharge displacement is reduced to cause reducing of the necessary torque, the torque fluctuation can be absorbed in the second deformation part 14b having the small elastic modulus K. Accordingly, the large torque can be transmitted with sufficiently absorbing the torque fluctuation.

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 positively display torque limiter function at the time of overload with detaching torque as designed without needing to set an axial friction moving member. SOLUTION: During normal operation of a compressor 3, a plurality of balls 8 are fittingly locked into hole parts 1d, 1e of a pulley 1 by the spring load of a conical spring 9, and in this state, the balls 8 are pressed to the inclined wall of a conical hole 6c of a hub 6 to transmit power from the pulley to the hub 6 and a compressor rotating shaft 5 via the fit-in parts of a plurality of balls 8. At the time of overload of the compressor 3, on the other hand, axial load applied to the balls 8 from the inclined wall of the conical hole 6c exceeds spring load of the conical spring 9, so that the balls 8 moves in the direction of escaping from the inclined wall of the conical hole 6c against the conical spring 9 so as to cut off power transmission from the pulley 1 to the hub 6.

Abstract: PROBLEM TO BE SOLVED: To provide a power transmitting device with a constitution of good assembly workability without using a rolling ball whereby at overload time, a torque limiter function can be well displayed. SOLUTION: Mutually among a flange part 11a integrally molded in an inner side holding member 11, washer 13, circular arc-shaped protrusion part 7f in a flange part 7a of a hub 7, and a washer 14, by tension of a belleville spring 15, is friction engaged mutually into contact. In this way, when a compressor 4 is in ordinary operation, rotation of the inner side holding member 11 in a drive side is transmitted to a hub 7 and a rotary shaft 6 through a friction engaging mechanism. On the other hand, at overload time, between the washer 13 and the circular arc-shaped protrusion part 7f in a flange part 7a of the hub 7, which is a friction engaging surface decreasing a coefficient of friction, a slip is generated, by this slip, the washer 13 is dropped to come off in a notched recessed part of the hub 7, to be displaced in an axial direction of the rotary shaft 6, in this way, pressing force of the belleville spring 15 is reduced, the flange part 11a is raced.

Abstract: PROBLEM TO BE SOLVED: To satisfactorily show torque limitter function with specified operation torque by providing a torque limitter mechanism for excessive load having a torque fluctuation absorbing function, and preventing a biting phenomenon of an elastic member. SOLUTION: When a compressor 4 is normally operated, the torque of an engine is transmitted to a rotary shaft 6 of the compressor 4 through a pulley 1, a rotor 2, a second holding member 13, a rubber elastic member 15, a first holding member 12, and hubs 10, 7. Under excessive load caused by, for example, locking of the compressor 4, the elastic member 15 is deformed. An outer peripheral surface of the elastic member 15 is slid on an inner peripheral surface of the first holding member 12 for interrupting power transmission. A projection 15D is formed on the elastic member 15 for forming gaps Y of a specified interval between an axial one end of the elastic member 15 and an inner circumferentially bent portion of the first holding member 12. It is thus possible to reduce torsional force applied to the elastic member 15 and absorb the torsional deformation of the elastic member 15 in the axial direction by the gaps Y.

Abstract: PROBLEM TO BE SOLVED: To provide a body grounding structure of an electromagnetic clutch, which is capable of easily grounding and fixing a body of the electromagnetic clutch without increasing the working man-hour and the number of components. SOLUTION: In an electromagnetic clutch, a grounding side end 11 drawn out to one end side of a stator housing 3 is fixedly calked to a calking part 28 provided on an arm support 19 for fixing the stator housing 3 to a refrigerant compressor. Thus, a body can be grounded in one calking operation, and the man-hour can be reduced. Further, since the calking part 28 is provided on the arm support 19, the calking part 28 can be easily worked comparing with a case in which the calking part 28 is formed on the stator housing 3 itself. Still further, since the grounding side end 11 is directly calked to the arm support 19, the number of components is not increased. Still further, since only one electric contact between the calking part 28 and the grounding side end 11 is sufficient, the reliability of conduction can be easily ensured.

SOLUTION: A drive side rotary member is constituted by a pulley 1 and a rotor 2 formed in a separate unit from this pulley 1, the rotor 2 is provided with a connection surface 2a extended in a radial direction of the rotor 2, and a second hole member 13 is connected to this connection surface 2a. In this way, by connecting the second hold member 13 to the connection surface 2a of the rotor 2 formed in a separate unit from the pulley 1, in the case that a position of the pulley 1 is to be moved in its rotary shaft direction by a change of specifications, the position of the pulley 1 connected to the rotor 2 is required to be only displaced in a rotary shaft direction.

Abstract: PROBLEM TO BE SOLVED: To interrupt transmission of torque at a predetermined torque even when the temperature of an elastic member drops. SOLUTION: Coefficient of linear expansion of an inner plate 113 is made larger than that of an outer plate 122. When temperatures of both plates 113 and 122 and an elastic member 130 drops, even though a transmission torque increases due to the temperature drop of the elastic member 130, a meshing quantity δ1 during torque transmission decreases because gap δ2 between the elastic member 130 and the outer plate 122 becomes larger. Consequently, the increase rate of torque transmission in regard to the temperature drop of the elastic member 130 is smaller compared to when materials (coefficient of linear expansion) of both plates 113 and 122 are the same. Thus, transmission of torque is interrupted at a predetermined torque even when the temperature of the elastic member 130 drops.
