摘要： In a method of joining two metal members by forming an annular groove at least on one of the two metal members to be joined and causing part of the material of the metal member to flow into the annular groove by plastic deformation to form a joint, at least one annular angled member is formed in the annular groove. The annular angled member extending the entire periphery of the annular groove is substantially triangular in axial cross-sectional shape. The joint has increased strength and can be formed with reduced pressure.

摘要： A rotary electric machine rotor comprises a rotary shaft which is formed with a plurality of protuberances projecting beyond a basic circle and extending in a lengthwise direction, and a core which is made of a plurality of core segments smaller in deformation resistance than that of the rotary shaft. The rotary shaft is plastically pressed into the core and has an annular groove formed at a position of the rotary shaft somewhat inward of an end face of the core. The core is plastically deformed and a part of the core is filled fully in the annular groove while axially pressing the core.

摘要： A joining structure comprises a shaft made of metal and a disc of metal more reducible than the shaft. The shaft has arcuate walls defined by a basic circle, and a plurality of projections each projecting from the basic circle and extending along the axis of the basic circle. The projections are spaced from each other so that the arcuate walls are disposed all between the projections. The disc has a hole of the same diameter as the basic circle. The shaft is forcedly inserted into the hole of the disc so that the projections cut into the disc to be rigidly joined to the disc with high concentricity between the shaft and the hole.

摘要： A method and apparatus for coupling two metallic members such as a shaft and a disc. The method includes forming an annular groove on a joint face or outer circumference of the metallic member having greater deformation resistance of the two members, for example, forming uneven portions on the bottom of the groove by knurling or the like. Working the other metallic member, for example, the disc; having smaller deformation resistance near its joint face so that the joint face opposing that of the other causes plastic deformation. Causing a part of the disc to fluidize and flow into the groove, thereby coupling both metallic members together.

摘要： A method for connecting two members to be connected comprises following steps. At first, a circumferential groove is formed on the connecting surfaces of the members to be connected. Secondly, axial recesses are formed on the inner surface of the groove. Thirdly, a connecting member is placed between the members to be connected. The connecting member is made of a material which has a smaller resistance against deformation than the members to be connected has and which has a required mechanical strength. Lastly, the connecting member is pressed and plastically deformed, resulting in that the connecting member flows into the groove and the recesses.

摘要： The present invention is to extrude helical internal gears and helical gears by pushing materials processed to any type of blank into a die unit successively by use of a punch, i.e., by passing the materials once through the die unit. The invention is directed to a die unit comprising an outer contour restraining container into which metal material blanks each having a central bore are to be inserted, a die placed contiguously below the container, these container and die being arranged to be circumferentially rotatable relative to each other, and upper and lower mandrels disposed inside the container and the die in alignment with their axes, respectively, and interconnected for being circumferentially rotatable relative to each other, the metal materials being successively pushed into gaps between the upper mandrel and the container and between the lower mandrel and the die by means of a punch to mold helical internal gears.
