摘要： The flame of a cutting torch is passed through a central longitudinal zone of an elongated blank so that the kerf forms two rack sections with substantially identical teeth thereon. Rack sections with such flame cut teeth are secured together in side-by-side relationship, with their teeth in endwise register, to form a rack exceeding the thickness of the blanks from which the rack sections are cut. Before flame cutting of the teeth is commenced, thin slices are flame cut from opposite faces of the blank which are to become the backs of the rack sections, to prevent warping of the flame cut rack sections along their lengths.

摘要： A COMPOUND ANNULAR BODY IS PRODUCED BY A FORGING OPERATION. INNER AND OUTER ANNULAR BODIES ARE TELESCOPICALLY ENGAGED ONE WITHIN THE OTHER, AND ARE PLACED WITHIN AN ANNULAR DIE HAVING RADIALLY OUTWARDLY EXTENDING PERIPHERALLY SPACED RECESSES. THE MATERIAL OF THE INNER ANNULAR MEMBER HAS A HIGHER MALLEABILITY THAN THAT OF THE OUTER ANNULAR MEMBER. AXIAL PRESSURE IS APPLIED TO THE CLOSELY FITTED ANNULAR MEMBERS IN THE DIE TO FORCE THE MATERIAL OF THE OUTER MEMBER INTO THE RECESSES TO FORM PROJECTIONS, AND TO FORCE THE MATERIAL OF THE INNER MEMBER INTO RECESSES IN THE INNER PERIPHERY OF THE OUTER MEMBER, THESE LATTER RECESSES RESULTING FROM THE RADIALLY OUTWARDLY DEFORMATION OF THE OUTER MEMBER. THE INNER AND OUTER MEMBERS ARE THUS INTERLOCKED AGAINST BOTH AXIAL AND ANGULAR RELATIVE DISPLACEMENT. THE TWO MATERIALS MAY BE METALLIC MATERIALS OR THE OUTER MEMBER MAY BE A METALLIC MATERIAL AND THE INNER MEMBER A SYNTHETIC RESIN MATERIAL. THE FORGING OPERATION MAY BE EITHER A HOT FORGING OPERATION OR A COLD FORGING OPERATION.

摘要： Provided is a mechanical structural member that can suppress deformation and has high precision and excellent quality. In a mechanical structural member (triangular threaded shaft 31) in which grooves (32) and teeth (33) are formed by plastic working and a hardened layer (31a) is formed on a surface of the teeth (33), the mechanical structural member has a sorbite structure, and Rockwell hardness in a region P excluding the hardened layer (31a) is 13 to 28 (HRC). A variation in the Rockwell hardness in the region P excluding the hardened layer (31a) is within 6 (HRC).

摘要： Provided is a gear material that is for a differential ring gear or the like, and that has a relatively large shape and has spur gear teeth or helical gear teeth at an outer periphery thereof, and with which the yield of a final product is improved, the operating cost of gear cutting by a hobbing machine is reduced, and the rate of cutting is dramatically increased to reduce a machining time, whereby the total manufacturing cost can be reduced. This gear material is in the shape of a ring having an outer diameter of at least 170 mm and an outer peripheral thickness of at least 30 mm, and has, at an outer peripheral surface thereof, spur gear teeth or helical gear teeth with a machining allowance of 0.2 mm to 2.0 mm on either side thereof.
