摘要： A pulley unit comprising two inner and outer annular bodies disposed coaxially and a one-way clutch interposed in an annular space between both the annular bodies, both ends in the axial direction of the annular space being sealed by a seal and at least the sealed portion of at least one seal being hidden by an annular member mounted to the inner annular body. By this structure, the sealed portion by the seal is protected from a direct splash of water, so that invasion of water through the sealed portion becomes unlikely to occur.

摘要： In an annular space between a pulley and a shaft body disposed coaxially with each other, a one-way clutch is interposed in an intermediate range in an axial direction and rolling bearings are disposed on both sides in the axial direction of the one-way clutch. A tightening distance for fitting between the one-way clutch and pulley is set to be smaller than that between the rolling bearing and pulley. Due to this structure, in a condition in which an excessive radial load acts upon the pulley, that radial load acts on not the one-way clutch but the rolling bearings on both sides thereof, so that a clutch operation of the one-way clutch can be carried out stably.
摘要翻译：在彼此同轴配置的皮带轮和轴体之间的环形空间中，单向离合器插入在轴向的中间范围内，并且滚动轴承设置在单向离合器的轴向两侧。单向离合器和滑轮之间的紧固距离设定为小于滚动轴承和滑轮之间的紧固距离。由于这种结构，在径向载荷作用在滑轮上的情况下，该径向载荷不作用于单向离合器，而是作用于其两侧的滚动轴承，使得单向离合器可以稳定地进行。

摘要： A one-way clutch for switching a power transmitting state and a power transmission interrupting state between an inner ring member and an outer ring member. At a plurality of circumferential portions of one of the inner ring member and the outer ring member, there are formed cam faces between the circumference of the one of the inner and outer ring members for forming wedge-shaped spaces which are narrowed in one circumferential direction. These cam faces are made to have a higher hardness than that of rollers which are individually arranged in the wedge-shaped spaces. As a result, the cam faces are suppressed from wear as the time elapses, and the wedge angle of the wedge-shaped spaces is kept substantially constant.

摘要： A one-way clutch for switching between a locking state in which an inner wheel and an outer wheel rotate synchronously, and a free state in which they rotate relative to each other. The one-way clutch includes a holding device having pockets for accommodating rollers provided at several positions on its circumference, and coil springs which are accommodated in each of the pockets in a compressed state for urging the rollers to a locking side of a pocket. The coil springs are in contact at points which span over 1/2 the width of the roller in the axial direction of the roller. As a result, a balanced urging force of the coil spring can be supplied to the roller, so that the rollers rotate smoothly and with a proper posture. Deflection of the coil springs is inhibited by alignment portions included at a surface of each pocket.

摘要： A one-way clutch has rollers individually disposed in wedge-shaped spaces formed at positions along a circumference between an inner annular body and an outer annular body which are disposed concentrically. The wedge angle of each wedge-shaped space is fixed at a preferred value. As a result, an engagement position of the roller becomes shallow when the roller is positioned on a narrower side of the wedge-shaped space and gaps between the roller and the inner and outer annular bodies become small when the roller is positioned on a wider side of the wedge-shaped space. Therefore, the rollers move smoothly when switching between the lock state and the free state.
摘要翻译：单向离合器具有单独设置在形成在同心设置的内环形体和外环形体之间的圆周的位置处的楔形空间中的辊。每个楔形空间的楔角被固定为优选值。结果，当辊位于楔形空间的较窄侧时，辊的接合位置变浅，当辊位于较宽侧时，辊与内外环形体之间的间隙变小的楔形空间。因此，当在锁定状态和自由状态之间切换时，辊平滑地移动。

摘要： A one-way clutch has an annular space through which an outer ring and an inner ring face each other, the outer ring and the inner ring being disposed inside and outside each other in a diameter direction and concentrically with each other. A lubricant for lubricating an inner peripheral face of the outer ring and an outer peripheral face of the inner ring on which rollers roll is prepared by mixing a urea-based consistency increasing agent into ester-based or synthetic oil-based base oil with a pressure viscosity coefficient (at a temperature of 25° C.) set at 12 GPa−1 or more. The lubricant provides for movement of state switching components to be stabilized even at a low temperature and wear of the state switching components and operating faces can be suppressed even at a high temperature.

摘要： A rolling bearing such as a rolling bearing for an alternator of an automobile, the life period of which is prevented from being shortened due to the temporal reduction of a radial internal clearance even in a high temperature environment. The rolling bearing includes a plurality of rolling elements rotatably arranged between an inner race and an outer race, and at least the inner race and the outer race are made of a steel material. An austenite residual rate of the inner race is smaller than an austenite residual rate of the outer race. The amount of dimensional expansion of the outer race due to the martensite transformation of residual austenite is larger than that of the inner race, so that the occurrence of clearance loss is suppressed even when dimensional expansion of the rolling elements occurs.
摘要翻译：一种滚动轴承，例如用于汽车的交流发电机的滚动轴承，即使在高温环境中，由于径向内部游隙也随之减少，其寿命被缩短。滚动轴承包括可旋转地布置在内座圈和外座圈之间的多个滚动元件，并且至少内座圈和外座圈由钢材制成。内圈的奥氏体残留率小于外圈的奥氏体残留率。由于残留奥氏体的马氏体相变导致的外圈的尺寸膨胀量大于内圈的尺寸膨胀量，所以即使发生滚动体的尺寸膨胀，也能够抑制间隙损失的发生。

摘要： A rolling, sliding part is made from a bearing steel, and the rolling, sliding surface thereof has a surface layer portion which is 56 to 64 in Rockwell C hardness, up to 12 vol. % in retained austenite content and 4 to 6 degrees in the X-ray half value width of martensite. Even if made from a common bearing steel, the rolling, sliding part is reduced in the likelihood of developing a WEA or like fatigue structure, consequently exhibiting a prolonged rolling, sliding life for use under severe conditions involving a high temperature, high speed, high load or high vibration.
