摘要： PROBLEM TO BE SOLVED: To provide a torque limiter mechanism which can surely interrupt power transmission at a required torque. SOLUTION: A screw is formed at a screw connecting portion 10 of a pulley 9 (a boss portion 9g) and a shaft 1a. The screw has a thread which is formed such that its fastening torque increases when the power has been applied to the pulley 9, In addition, a fracture 1i is provided so as to fracture by an axial force caused by the fastening, when the fastening torque applied to the screw connecting portion 10 exceeds the required value. By this configuration, the stress for fracturing the fracture portion 1i is not a shear stress, but becomes mainly a tensile stress. In addition, because the tensile stress almost uniformly distributes on the cross section differently from the case of the shear stress, the stress distribution at the fracture portion 1i can be relatively accurately estimated and analyzed. Therefore, the necessity of the trial and error method for determining the size, materials, etc. of the fracture portion 1i is reduced, and the design and development are easily carried out, and the fracture portion 1i can be surely fractured at the required torque without fracturing by fatigue.

摘要： PROBLEM TO BE SOLVED: To provide a new power transmission different from conventional ones and capable of stably actuating a torque limiter function.
SOLUTION: A metallic ring hub 7 is press-fitted and fixed on a metallic inner hub 6, and the ring hub 7 and the inner plate hub 8 are connected to each other by a material of butyl rubber, etc. lower in heat resistance than the ring hub 7. Consequently, as a contact surface Fs becomes a metal friction surface, a dimensional change of the contact surface Fs due to a creeping phenomenon becomes sufficiently small in a negligible degree in comparison with resin. Accordingly, it is possible to stably actuate the torque limiter function for a long period of time as fluctuation of friction force generated on the contact surface Fs can be made small for a long period of time. Additionally, as transmission of torque is blocked as the connecting part 9 breaks by frictional heat when the ring hub 7 slides to the inner hub 6 on the contact surface Fs as transmission torque exceeds the transmittable maximum torque, it is possible to certainly block transmission of the torque even when the contact surface Fs is dissolved and deposited by the frictional heat.

摘要： PROBLEM TO BE SOLVED: To avoid possibility that a belt to receive a power from an internal combustion engine is broken if a compressor is locked when a refrigerant compressor is connected to the internal combustion engine via a one-way clutch in place of an electromagnetic clutch in order to drive, for example, the refrigerant compressor for a vehicle air-conditioner also by an electric motor.
SOLUTION: When a roller-type one-way clutch is used, a second pocket part 53c is provided on one side of a wedge surface 53b in addition to a first pocket part 53f which is provided on the other side of the wedge surface 53b to be engaged with a roller 53a and put into an idling condition if the roller 53a is dropped in a reverse turn so that the roller 53a rides over the wedge surface 53b when an excessive torque is transmitted, and is dropped into a second pocket part 53c and put into an idling condition. When a sprag type one-way clutch is used, it is put into an idling condition by intentionally generating roll-over at a predetermined load torque value.

摘要： PROBLEM TO BE SOLVED: To increase clutch transmission torque in a self-hold type clutch.SOLUTION: A projection 531d extending in a rotational axis direction is provided in a spool 531 of a first electromagnetic coil 53, and a yoke 55 is fitted to the outer peripheral side of the projection 531d. The yoke 55 is held by the spool 531 with higher dimensional accuracy and form accuracy than a permanent magnet 51, and thereby vibration of the outer peripheral surface of the yoke 55 with respect to the rotational axis can be suppressed. Consequently, a gap S provided on the outer peripheral side of a movable body 52 is made small, and clutch transmission torque can be increased.

摘要： PROBLEM TO BE SOLVED: To suppress the occurrence of erroneous operation in a power transmission device 1 in which a permanent magnet 2 is used.
SOLUTION: This power transmission device 1 includes a magnet attitude changing means for changing the attitude of the permanent magnet 2. A clutch is changed over between ON and OFF by changing the attitude of the permanent magnet 2 by the magnet attitude changing means to change over between a first magnetic circuit for flowing a magnetic flux to a rotor 4 and an armature 7 and a second magnetic circuit for flowing a magnetic flux weaker than that in the first magnetic circuit to the rotor 4 and the armature 7. Since the magnetic attractive force between the rotor 4 and the armature 7 is reduced when the clutch is OFF (attitude in which the second magnetic circuit is formed), the occurrence of such an erroneous operation that the rotor 4 and the armature 7 are intentionally connected to each other can be suppressed without allowing the armature 7 to be attracted to the rotor 4 even if a gap 6 is reduced by vibration and external force.
