摘要： A limiter device is provided in a variable displacement compressor capable of varying a discharge displacement per revolution and compressing a fluid in a cycle. The limiter device includes an operating characteristic acquiring means for acquiring a predetermined characteristic during a compression operation of the compressor, and a varying means for varying the discharge displacement of the compressor to a minimum side when the predetermined characteristic obtained by the operating characteristic acquiring means exceeds a predetermined value. Thus, the limiter device can prevent the compressor from being brought into trouble such as locking and can protect a driving belt and other auxiliary equipment on a side of an engine, while it is unnecessary to provide a pulley with a limiter function.

摘要： A hole is formed in a damper rubber, where by when a compressive load is small, pillar portions undergo a flexural deformation so as to result in buckling deformation. On the other hand, when the compressive load becomes large, the hole collapses and the damper rubber undergoes a compressive deformation so as to collapse itself. Thus, since the damper rubber has a non-linear characteristic such that an elastic modulus thereof at an amount of deformation exceeding a predetermined amount is larger than that at an amount of deformation less than the predetermined amount, the transmission of a large torque can be implemented while absorbing a torque fluctuation sufficiently.

摘要： A power transmission system has a Neidhart structure in which a damper is shearing-deformed while being press-deformed when torque is applied to a pulley. The torque is transmitted from the pulley to a center hub by the reaction force in response to a vector component of the deformation of the damper, parallel to the pulley rotation direction, while a torque fluctuation is reduced by the deformation of the damper. Thereby, it is possible to set an elasticity modulus of the damper to be smaller. Therefore, it is possible to provide a compact power transmission system having a reduced torque fluctuation.

摘要： A torque limiting mechanism includes an axial space formed in a cylindrical wall of a pulley, and a pin protruding and extending from a back surface of a discharge disc. The pin is inserted into the axial space, and a rubber damper is installed between the inner surface of the axial space and the pin. When torque difference between the pulley and the discharge disc exceeds a threshold, a root portion of the pin is broken to separate the discharge disc from the pulley, thereby interrupting rotation transmission from the pulley to the discharge disc.

摘要： In a flexible joint having a first rotating body connected to a shaft of an engine, a second rotating body coaxially connected to the first rotating body via a first rubber damper, and a third rotating body whose outer circumference is coaxially coupled with the second rotating body via a second rubber damper and whose center axis is coaxially connected to a shaft of a compressor, the second rotating body is rotatably held by a front housing of the compressor. Accordingly, eccentric load acting on the joint according to the rotation thereof is received by the housing of the compressor so that the shaft of the compressor receives lower bending moment. Further, as the first and second rubber dampers are used, a composite elastic coefficient thereof is smaller so that torque fluctuation applied to the joint is adequately absorbed.

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： 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.
