Patent number: 7156743Abstract: An inexpensive mechanical fuse having a high fatigue limit ratio and high rupture reliability, and superior in forming performance, and a method of manufacturing the same are presented. The mechanical fuse is composed of Fe-based sintered alloy, and comprises an inner rim 2 fixed to one power transmission shaft, an outer rim 3 fixed to the other power transmission shaft, and plural arms 4 for linking the inner rim 2 and outer rim 3, which are formed integrally. The arms 4 include rupture portions 6 which are ruptured when exposed to an overload torque. By treating in steam, an iron oxide phase is formed in the surface layer and pore inner wall. The iron oxide phase is effective to form round pores and lower the notch sensitivity. As a result, the fatigue strength and fatigue limit ratio are enhanced.Type: GrantFiled: November 27, 2001Date of Patent: January 2, 2007Assignees: Hitachi Powdered Metals Co., Ltd., Denso CorporationInventors: Tadayuki Tsutsui, Kei Ishii, Yoshihiro Tanimura, Kouji Yamada, Yuuichi Aoki

Publication number: 20030121567Abstract: 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.Type: ApplicationFiled: December 5, 2002Publication date: July 3, 2003Inventors: Satoshi Sugiyama, Syoichi Takenouchi, Yoshihiro Tanimura, Keizo Takeuchi, Masaki Shimizu, Takashi Ishikawa, Yoshitada Katayama, Hidehito Kito, Suehisa Sugisaka
