摘要： A power transmission apparatus which can function as a torque limiter during an overload condition. A Belleville spring is provided for generating mutual frictional engagement in areas between a flange part integral to an inner holder member, a washer, arc shaped projections of a flange part of a hub and a washer. As a result, during a normal condition of a compressor, the rotating movement of the inner holder member located adjacent to the rotating movement source is transmitted via the frictional engagement mechanism to a hub and then to a rotating shaft. Contrary to this, during an overloaded condition, a slippage is generated in the area between the washer and the arc shaped projections of the flange part of the hub as a frictional engaging area of a lower coefficient of friction. This slippage causes the washer to sink into the recess of the hub, which causes the washer to be displaced in the direction of the axis of the rotating shaft, which causes the pressing force to be reduced in the Belleville spring, resulting in a free rotating movement of the flange part.

摘要： A friction clutch such as an electromagnetic clutch, in which a driving friction surface is formed on a rotor integral with a rotationally driven pulley and a driven friction surface in opposed relation to the driving friction surface is formed on an intermediate member pivotally mounted on a boss by a pin, is disclosed. When the rotor is in rotation, the armature portion of the intermediate member is attracted by an initial energizing means for generating a comparatively small force such as an electromagnetic coil so that the intermediate member is rotated around the pin. When the friction surface of the intermediate member is lightly pressed against the friction surface of the rotor, the friction force exerted tangentially to the contact surface causes the intermediate member to rotate further around the pin and generate a large force along the normal. Thus, the friction force is increased thereby making it possible to transmit a large power from the rotor to the boss through the intermediate member.

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 order to reduce its size of a coil-rotation type electromagnetic clutch in an axial direction and to prolong the life of its brush, a sliding current supply mechanism, which has slip rings and slidable brushes which contact the slip rings, is located inside an inner circumference of a housing boss of a compressor. The current is supplied to an electromagnetic coil via the sliding current supply mechanism. Since the sliding current supply mechanism is located in the boss, a current supply passage is formed without increasing the size of the clutch in axial direction. Thus the installation of the electromagnetic clutch in the engine room is facilitated. Furthermore, since the sliding current supply mechanism is located near the rotational center of the clutch, the life of the brush is prolonged due to the small peripheral velocity of the brush.
摘要翻译： 为了减小线圈旋转型电磁离合器在轴向上的尺寸并延长其电刷的寿命，具有滑环和滑动环接触的滑动电刷的滑动电流供给机构位于 压缩机的壳体凸起的内圆周。 电流通过滑动电流供给机构供给电磁线圈。 由于滑动电流供给机构位于凸台中，因此在不增加离合器的轴向尺寸的情况下形成电流供给通道。 因此，容易将电磁离合器安装在发动机室中。 此外，由于滑动电流供给机构位于离合器的旋转中心附近，所以由于刷子的圆周速度小，刷子的寿命延长。

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： In order to improve the magnetic efficiency and the assembling productivity of a coil-rotation type electromagnetic clutch, an electromagnetic coil is located in a ring-shaped recess of a rotor, and friction surfaces facing an armature are formed on both ends of an inner cylindrical portion and an outer cylindrical portion. A friction plate is located in the recess and closer to the armature than the electromagnetic coil. A magnetic shield is located at a place corresponding to the middle of the friction plate in the radial direction. The friction plate is fixed to the ends of the inner cylindrical portion and the outer cylindrical portion by securing protrusions of the friction plate to grooves formed on the inner cylindrical portion and the outer cylindrical portion.

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： 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.
