摘要： PROBLEM TO BE SOLVED: To enhance a rated load and prolong a life without making a dimension of outer shape large in a self-aligning bearing in which one end of a rotation shaft thermally expanding/shrinking in an axial direction is positioned in the axial direction. SOLUTION: The self-aligning bearing 4 positions/supports one end of the rotation shaft in the axial direction and permits flexure of the rotation shaft. The self-aligning bearing 4 is made to a constitution of a double row cylindrical roller bearing with an aligning ring. A group of cylindrical roller 13 of the first row are clamped and positioned by a radially inward flange 15 provided on an axial midway of an outer ring 11 of which an outer peripheral surface is made to a spherical shape and a flange 16A provided on one outer end of two inner rings 12A, 12B in the axial direction. A group of cylindrical roller 13 of the second row are clamped and positioned by the flange 15 of the outer ring 11 and a flange 16B provided on the other outer end of the two inner rings 12A, 12B in the axial direction. Thereby, a total effective contact length of the double row cylindrical rollers 13 and an inner diameter dimension of the outer ring 11 can be made as large as possible without making a width dimension and an outer diameter dimension of the outer ring 11 in the axial direction large.

解决方案：自调心轴承4在轴向方向上定位/支撑旋转轴的一端，并允许旋转轴弯曲。自对准轴承4由具有对准环的双列圆柱滚子轴承构成。第一排的一组圆柱滚子13通过设置在外圈11的轴向中间的径向向内的凸缘15夹紧并定位，外圈11的外周表面形成为球形，凸缘16A设置在一个外部两个内圈12A，12B的轴向的端部。第二排的一组圆柱滚子13由外圈11的凸缘15和设置在两个内圈12A，12B的另一个外端上的轴向方向夹紧并定位。由此，可以使双列圆筒滚子13的总有效接触长度和外圈11的内径尺寸尽可能大，而不使外圈11的轴向尺寸和外径尺寸大。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To solve such problems that, when a cylindrical roller bearing with an aligning ring is used as a bearing supporting a roll attached to a continuous casting machine, there is a need of using a roller having a small diameter in a limited space, and the P.C.D. (Pitch-Circle-Diameter) of the roller is reduced, and the load capacity of the bearing is reduced as well.
SOLUTION: A roll 3 for forming is divided into three pieces. Thus, when a slab 1 is conveyed to a prescribed place so as to be held by each roll 3 for forming, the amount of deflection caused by loading worked from the slab is reduced, so that there is no need of performing the support of each roll 3 for forming by using a bearing having center-alignability, but it is made possible to deal therewith only by using a common cylindrical roller bearing 16. By the degree that there is no need of using a bearing having center-alignability, the number of cylindrical rollers 19 can be increased, or the diameter of the cylindrical roller 19 can be made large. Thus, load capacity can be increased.

摘要： PROBLEM TO BE SOLVED: To provide a structure of a sealing device which can surely supplement grease over a wide area in a grease sealed space while allowing the discharge of the grease in supplementing the grease.
SOLUTION: In an inner seal 2 of the sealing device 1, a through hole 28 for grease discharge is formed in the middle in the upper radial direction of an annular plate 24 of an annular core metal 21. By this, when supplementing the grease to a target to be sealed, new grease to be poured is sequentially retained from the lower part of the target to be sealed and old grease is discharged sequentially from the upper part of the sealing device 1, and the new grease and the old grease can be easily replaced and the new grease easily reaches the wide area in the target to be sealed.

摘要： PROBLEM TO BE SOLVED: To prevent the breakage of a roll and a bearing when abnormal load acts on the roll caused by abnormal passing-through of a cast slab, etc. SOLUTION: A disk spring is used as a reaction receiving means acting the load to the roll by receiving the reaction of the roll. The belleville spring loads a load corresponding to a flexible amount with the reaction of the roll when the cast slab is passed through. Then, when the reaction of the roll caused by the abnormal passing-through of the cast slab exceeds the regulated value, it is adjusted so as to be able to read smaller load than the load corresponding to the flexible amount. In this way, the load to the roll when the abnormal cast slab is passed through, is relaxed and the breakage of the roll and the wearing can be prevented in advance from happening.
