摘要： PROBLEM TO BE SOLVED: To realize a manufacturing method capable of securing a yield of a material by eliminating a sink part 55 formed on an inner circumference of an intermediate raw material 17 for an outer ring for manufacturing an outer ring for a rolling bearing without cutting.
SOLUTION: While an intermediate raw material 17 for an outer ring is set to a retaining recessed part 69 provided in a die 66, a crushing punch 64 is lowered to an inner circumference of the intermediate raw material 17 for the outer ring. Thereby, a peripheral portion of a sink part 55 formed on the inner circumference of the intermediate raw material 17 for the outer ring is crushed by an outer circumference at a tip of the crushing punch 64, so as to eliminate the sink part 55. Thereby, the problem can be solved.

摘要： PROBLEM TO BE SOLVED: To enable a dimension of the outer diameter of a counterlock to obtain a proper hub unit for supporting a wheel with ease and to enhance efficiency of axial force when calking is operated. SOLUTION: The method includes the step of performing oscillating calking for a cylindrical part for calking formed on the axial end side by a calking tool 18 and the step of supporting end face 29 of a counterlock part 28 by the counterlock end face receptacle tool 30 when a second inner ring 3 is fixed to a first inner ring 2 by a formed calking part 16. The hub unit can properly maintain a dimension of the outer diameter of the counterlock when contact point of the receptacle is less than 250 MPa. In addition, the hub unit successfully secures the dimension of the outer diameter of the counterlock so as not to constrain the hub unit in radial direction in that case and enhances the efficiency of the axial force when the calking is operated.

摘要： PROBLEM TO BE SOLVED: To reduce manufacturing cost by improving yield by preventing the occurrence of a micro crack starting from a groove bottom of a fracture surface when an annular third intermediate material 21 is diametrically enlarged by form rolling to form a fourth intermediate material 22.SOLUTION: After a circular recess 45 is formed by rocking die forging on one side of a disk-shaped first intermediate material 19, a center portion thereof is punched from the side opposite from the circular recess 45 to form the third intermediate material 21. A fracture surface formed on an inner circumferential surface due to the punching is located at an axial-direction intermediate portion. The fracture surface is squeezed in the initial stage of the rolling work and formed in a smooth surface. Thus, in the stage at which the diameter of the third intermediate material 21 is enlarged, any groove forming a starting point of the occurrence of crack is not present on an inner circumferential surface of the third intermediate material 21.

摘要： PROBLEM TO BE SOLVED: To reduce the manufacturing cost by enhancing the yield by preventing very small crack with its starting point being a groove bottom of a fracture surface when a fourth intermediate material 22 is formed by diametrically expanding an annular third intermediate material 21 by form rolling. SOLUTION: After forming a circular recess 45 in one surface of a disk-shaped first intermediate material 19 by rocking-forging, a center part is punched out from the side opposite to the circular recess 45 to form the third intermediate material 21. In association with the punching, a fracture surface generated in an inner circumferential surface is located at an intermediate part in the axial direction. The fracture surface is squeezed in the initial stage of the form rolling and formed into a smooth surface. Thus, in the stage in which the diameter of the third intermediate material 21 is increased, any groove forming a starting point of the crack is not present in the inner circumferential surface of the third intermediate material 21.

摘要： PROBLEM TO BE SOLVED: To easily and correctly perform work for forming a calked part by radially, outwardly and plastically deforming a cylinder part 13a provided on an inner end of a hub 2, thereby accomplishing simplification of a structure of a calking part forming device 21. SOLUTION: When the calked part is formed, a pressing mold 24 is downwardly displaced, and a ring-like working surface 27 provided on a lower end surface of the pressing mold 24 is pressed to the whole periphery of a distal end edge of the cylinder part 13a. In this state, the pressing mold 24 is downwardly pressed toward the hub 2 without pivoting the pressing mold 24 relative to the hub 2. The cylinder part 13a is thereby radially, outwardly and plastically deformed to the whole periphery simultaneously along the working surface 27. COPYRIGHT: (C)2008,JPO&INPIT
