Abstract: A bearing assembly is disclosed which addresses the problem of axially retaining a bearing journaled onto a shaft within a casing in an axially compact and technically economic and reliable way by first mounting a retaining plate (6) onto an outer race of the bearing (1). The mounting can be achieved by press fitting onto a shoulder so that the retaining plate can rotate relative to the outer race. The bearing is then journaled onto a shaft (4) and inserted into a compact casing (3) so that the outer race is guided into a housing (2) formed in an end wall of the casing (3). The retaining plate can then be rotated as required to align fastening bosses (7) with holes (8) to be engaged by screws (9) so that the retaining plate us urged axially against the outer race.

Abstract: A method for increasing structural strength of spokes of a bicycle or a motorcycle, which adopts a mechanically processing measure to increase the structural strength of the bending section of the spoke. The spoke is many times compressed to process and harden the bending section of the spoke so as to enhance the metal strength (shearing strength) of the bending section. At the same time, the wire diameter of the spoke (cross-sectional area) is increased due to compression in accordance with the principle that shearing load=shearing strength×cross-sectional area. With least metal material and lower processing cost, the spoke can have highest structural strength.

Abstract: Metal cold-working tooling and a method of employing such tooling. The tooling is used to produce deformation in a workpiece, to provide a selected beneficial residual stress profile in the workpiece, in order to provide high fatigue life structures in a minimum number of manufacturing steps. An indenter is used to coldwork a workpiece, causing dimples in the workpiece. Preferably, the dimples are provided with a shape formed by application of a uniform pressure profile to the workpiece surface. As optimized, a relatively uniform beneficial residual stress profile is provided at both the surface and at the midplane apertures in a workpiece, so as to improve overall fatigue life. Also, an improved indenter tool profile shape is described, having a smoothly curved indenter surface portion. And, the use of consumable lamina wafers provides the benefit of easy application of uniform stress profile to a workpiece.

Abstract: Disclosed is an elongated metallic article having a curved section therein which has a first part formed on an outside part of the curved section, and a second part formed on an inside part of the curved section. The first part was initially deformed beyond a region of twin boundary deformation, but was thereafter returned to the region of twin boundary deformation. The second part was left deformed beyond the region of twin boundary deformation. When a compressive load is applied to the thus prepared article, and the first part and the second part are both compressed, the first part can deform more readily than the second part so that the article deforms into a more straight shape as its deformation progresses. Thus, the article may be made resistant to buckling in spite of the presence of the curved section.

Abstract: A method of stress inducing transformation from the austenite phase to the martensite phase by conducting cold working on material of austenite stainless steel in the temperature range from the point Ms to the point Md. The above cold working is a biaxial tensing. An intermediately formed hollow body is made, which includes a ferromagnetic portion and a non-magnetic portion contracting inward. Then, the intermediately formed body is subjected to a stress removing process in which residual tensile stress is removed from an intermediately formed body. In the stress removing process, it is preferable that a punch is press-fitted into the intermediately formed body so as to expand a non-magnetic portion and then the intermediately formed body is drawn with ironing while the punch is inserted so that the residual tensile stress can be changed into the residual compressive stress in the non-magnetic portion.
