摘要： In a sealing device for a bearing, a sub-seal lip is configured such that a slide contact surface is formed like an annular band. As the rotation speed of the bearing increases, the width of the slide contact surface is reduced by a centrifugal force. Thus, sliding friction can effectively be minimized. The torque of the bearing can be prevented from increasing at high-speed rotation. Even when the centrifugal force increases somewhat, only reduction in the width of the slide contact surface is caused. Thus, a slide-contacted state can be maintained. Consequently, the problem of floating-up of the sub-seal lip from a slinger is difficult to occur.
摘要翻译：在用于轴承的密封装置中，副密封唇构造成使得滑动接触表面形成为类似于环形带。随着轴承的转速增加，滑动接触面的宽度由离心力减小。因此，可以有效地减小滑动摩擦。可以防止在高速旋转时轴承的转矩增加。即使离心力稍微增加，也仅导致滑动接触面的宽度减小。因此，可以保持滑动接触状态。因此，难以发生副密封唇从抛油环上浮的问题。

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 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 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： 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： There is provided a clutch release bearing in which a water resistance is enhanced. At a side axially opposite from one side where an outer ring rib of a clutch release bearing is formed, there is provided a first seal member externally fitted to an outer ring to be fixed thereto. A seal lip disposed in sliding contact with an outside-diameter surface of an inner ring is formed at a radially-inward distal end of the first seal member. An annular guide is provided at a bearing-outward side of the first seal member, and an axial lip which extends toward the outside of the bearing and extends to be disposed radially outwardly of the guide is formed at a bearing-outward side face of the first seal member. The axial lip is disposed in non-contact, close relation to the guide to form a labyrinth. A radially outwardly-open groove is formed in a joint portion of the axial lip joined to the first seal member.
