    摘要： A sealed rolling bearing in which a rolling member is disposed in a bearing space formed between an outer race and an inner race to rotate the outer race and the inner race relatively to each other, and rotation seal members are disposed at both ends of the bearing space in the axial direction thereof while a stationary seal member is disposed on the side of the inner race, thereby sealing the bearing space. The bearing is provided with a vent on the side of the inner race for approximating a fluid pressure in the bearing space to an outside fluid pressure by causing the inside of the bearing space to communicate with the outside when the state of fluid in the bearing space and state of the outside fluid have a predetermined relationship.

    摘要： When an inner race (12) rotates at a speed lower than a predetermined speed, a sealing body (27) contacts the sealingface part (21c), but when the inner race (12) rotates at a speed more than the predetermined speed, a contacting pressure to a sealing face part (21c) is reduced or the sealing body (27) is isolated so as to form a non-contacting seal, and therefore, for example, at the low speed, the sealing body (27) forms a contacting seal, thereby to compensate a low speed-low sealing ability of the non-contacting seal such as the labyrinth seal, and on the other hand, at high speed rotation, the sealing body (27) reduces the contacting pressure to the sealing face part (21c), and otherwise separates therefrom to form the non-contacting seal as the labyrinth seal, whereby it is possible to solve the problem of heating or abrasion at the contacting part. Further, a sleeve (122) is mounted on the supporting edge (12a) of the inner race (12), thereby to secure the sealing device (120) without processing a screwing hole in the inner race (12). Moreover, the sleeve (122) is optionally processed with a screwing hole (122a), to thereby easily fix the sealing device (120) by the bolt (124).

    摘要翻译： 当内座圈（12）以低于预定速度的速度旋转时，密封体（27）接触密封面部分（21c），但当内圈（12）以大于预定速度的速度旋转时， 密封面部分（21c）的接触压力减小或密封体（27）被隔离以形成非接触式密封，因此，例如在低速下，密封体（27）形成 接触密封，从而补偿非接触式密封件如迷宫式密封件的低速低密封能力，另一方面，在高速旋转时，密封体（27）降低与密封面的接触压力 部分（21c），否则从其分离以形成作为迷宫式密封件的非接触式密封，由此可以解决接触部分处的加热或磨损的问题。 此外，套筒（122）安装在内座圈（12）的支撑边缘（12a）上，从而固定密封装置（120），而不会处理内座圈（12）中的螺纹孔。 此外，套筒（122）可选地用螺纹孔（122a）处理，从而通过螺栓（124）容易地固定密封装置（120）。
