摘要： PROBLEM TO BE SOLVED: To achieve a small-sized and simple processing device for compression-bending.SOLUTION: A processing device comprises heating means for heating a metal tube, propulsion means for propelling the metal tube, and a clamp arm which grips the metal tube and is rotatable around a spindle part. Further, the processing device is equipped with guide means which revolves the point of the metal tube gripped by the clamp arm around the spindle part with propulsion of the metal tube and applies bending moment to the metal tube, and a bearing for rotatably supporting the clamp arm at the spindle part. The bearing comprises one or more bearings with brake means each of which includes an inner ring and an outer ring which are coaxially disposed, a support body which is interposed between the inner ring and the outer ring in such a manner that the inner ring and the outer ring can rotate relatively to each other, and brake means which contacts the inner ring or the outer ring and suppresses the relative rotation of the inner ring and the outer ring by frictional force. The brake means suppresses rotation of the clamp arm during the process of bending the metal tube, whereby compressive force is applied to the metal tube.

摘要： Described is a rolling bearing (1) for a rocker arm, said rolling bearing comprising an at least partly circular outer part (2), an at least partly circular inner part (3) and a number of rolling elements (5) which are fitted between the outer part (2) and the inner part (3). The rolling bearing is peculiar in that at least one of the rolling elements (5) comprises two opposite, curved side faces (6, 7), which viewed in at least one cross-sectional constitutes arc lengths of the same imaginary circle (10), and which constitutes contact faces for the outer and the inner circular part (2, 3) respectively, and at least one side surface (8, 9), which lies within the mentioned imaginary circle (10). It is hereby obtained that the number of rolling elements in the bearing can be increased, thereby reducing the load on each single rolling element subject to the same total load rate, thereby increasing the total load bearing capacity of the bearing. This is due to the fact that at least a part of the roller face of the traditional circular rollers which do not get into contact with the outer or inner part of the bearing through small reciprocating angular rotations is omitted thereby significantly reducing the space taken up by each of the rolling elements in the circumferential direction of the bearing.

摘要： PROBLEM TO BE SOLVED: To provide a method and system which designs a roller bearing enabling economical bearing designing by making know-how of bearing design unnecessary and reducing man-hours of designing, improves rigidity as a shaft system, extends a lifetime, miniaturizes the bearing at same load capacity, and reduces rotation torque. SOLUTION: This system includes: a bearing load calculation means calculating bearing load; a load capacity calculation means calculating load capacity necessary for the bearing based on the calculated bearing load; a search means searching candidates of part numbers of bearings satisfying load capacity from a database; and a selection means selecting a bearing part number from the candidates of bearing part numbers with following selection standard. Internal specifications and major dimensions of the optimum bearing according to conditions under which the bearing is used are automatically determined with using an optimization method. An approximation method such as a mathematical method and a response curved surface method, and a search method such as an experimental design, genetic algorithm and a simulated annealing are applied to the optimization method.
