摘要： PROBLEM TO BE SOLVED: To provide a bearing device used for supporting the fixed end of a roll in a continuous casting facility and suppressing abrasion and separation. SOLUTION: A face-to-face duplex conical roller bearing allows the inclination of the roll to some extent. By exhibiting an original function to support an axial load, it is possible to support the fixed end of the roll. Thereby, in comparison with the use of a conical roller bearing with an aligning ring, load carrying capacity is increase. Also, in comparison with the use of a self-aligning roller bearing, abrasion and separation are effectively suppressed. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a bearing device capable of suppressing invasion of foreign substance from outside and appropriately lubricating a rolling bearing by oil mist lubrication.
SOLUTION: As a gap between a center axis 5a and an inner ring 5b is sealed by an O-ring OR, in the case that pressure in the roller bearing 10 decreases, for example, during a maintenance operation and the like, invasion of foreign substance such as rolling oil from the gap between the center axis 5a and the inner ring 5b can be suppressed and dilution of lubricating oil in the rolling bearing 10 is suppressed and thus it is possible to secure its long service life. In the case that air and the lubricating oil are transported from the center axis 5a to the inner ring 5b, as leakage from the O-ring OR is suppressed, the air and the lubricating oil can be supplied to the rolling bearing 10 under an appropriate pressure.

摘要： PROBLEM TO BE SOLVED: To provide a roll bearing unit, which can be applied even to a portion having a large radial load in a continuous casting machine guide roll in a layout-free manner.
SOLUTION: When a radial load is applied from an ingot to a roller 4, it is supported by a cylindrical roller bearing. At that time, when a thrust load which acts also in the axial direction is given, for example, to the left in Fig. 3, movement of the roller to the left can be limited since a flange part 12e of an inner ring 12b of a right cylindrical roller bearing 12 abuts on the outer end of a cylindrical roller 12c to support the thrust load. When the thrust load is applied to the right, movement of the roller 4 to the right can be limited since a flange part 12e of an inner ring 12b of a left cylindrical roller bearing 12 abuts on the outer end of the cylindrical roller 12c to support the thrust load. Accordingly, the thrust load can be supported by a pair of cylindrical roller bearings 12, and the flexibility of layout can be extended without the concept of fixed side or free side.

解决方案：当从锭到辊4施加径向载荷时，它由圆柱滚子轴承支撑。 此时，当在轴向方向上作用的推力载荷例如在图1中向左作出时， 如图3所示，由于右圆柱滚子轴承12的内圈12b的凸缘部12e与圆柱滚子12c的外端抵接以支撑推力载荷，所以可以限制滚轮向左移动。 当推力负载施加在右侧时，由于左圆柱滚子轴承12的内圈12b的凸缘部分12e邻接圆柱滚子12c的外端，所以可以限制滚轮4向右移动，以支撑 推力载荷。 因此，推力载荷可以由一对圆柱滚子轴承12支撑，并且可以延长布局的灵活性，而不需要固定侧或自由侧的概念。 版权所有（C）2009，JPO＆INPIT
