摘要： The invention relates to a variable roll width type rolling roll constructed such that in order to enhance strength by eliminating stress concentration on a structure which drivingly couples a roll on a drive side to the other roll, a sleeve is fitted onto a coupling rod projecting coaxially from an arbor on a drive side, rolls are provided on the arbor and sleeve, respectively, to be supported by bearings, and the coupling rod is coupled to the sleeve by a screw gearing mechanism to make the sleeve movable in its axial direction so that the width of a roll can be varied. A location of a concavo-convex engagement effected by a spline or key or the like for transmitting rotation of the arbor to the sleeve is positioned outwardly of the center in the axial direction of the bearings for the sleeve so that such concavo-convex engagement is not affected by a bending due to rolling reaction forces, thereby preventing stress concentration.
摘要翻译：本发明涉及一种可变辊宽型轧制辊，其特征在于，为了通过消除驱动地将驱动侧的辊与另一辊驱动连接的结构上的应力集中来提高强度，将套筒安装在同轴的连接杆上驱动侧的心轴分别设置在心轴和套筒上，由轴承支撑，并且联接杆通过螺纹传动机构联接到套筒上，以使套筒沿其轴向移动，使得辊的宽度可以变化。通过用于将心轴转动到套筒的花键或键或类似物实现的凹凸接合的位置位于轴套的轴向方向上的中心的外侧，使得这种凹凸接合是不受轧制反作用力的弯曲影响，从而防止应力集中。

摘要： This invention aims at manufacturing a metal support capable of activating a catalyst in a short period of time, and, especially, a method of combining an insulating film-carrying heat resisting alloy having an insulating film consisting mainly of alumina with a heat resisting alloy by arranging a forcibly reducing metal capable of thermodynamically reducing alumina and a solder-laminated bond so that the forcibly reducing metal is in contact with the insulating film-carrying heat resisting alloy, and soldering these metals to each other by heating the same in a non-oxidizing atmosphere. Consequently, only the portions that are to form conductive passages in a honeycomb structure can be combined, and heat resisting metals having insulating oxide films on the surfaces thereof firmly so that they have conductivity. A preheated type metal support capable of being heated at a limited surface layer portion on its exhaust gas inlet side and having excellent cleaning performance can be provided by using this soldering method.
