摘要： An axial flow fan motor having an impeller molded integrally with a shaft from a synthetic resin. The shaft is easily assembled with a bearing arrangement by being brought into tight contact with the inner ring of the bearing arrangement and is reliably fixed thereto in the elastic region of the shaft. A through hole is formed in the shaft along its central axis. After the shaft is fit into the inner ring of the bearing arrangement, a metal pin is pressed into the axial through hole. Because the pin is pressed in, the shaft is elastically expanded and brought into tight contact with the inner ring and fixed thereto in the elastic region of the shaft. Furthermore, the distal end portion of the shaft elastically outwardly expands and is pressed against the end surface of the inner ring, thereby preventing the bearing arrangement from coming off the shaft.

摘要： PROBLEM TO BE SOLVED: To provide an oil impregnated sintered bearing designed to prevent leakage of lubricating oil and outgas and to improve anticorrosion, while securing lubricity of a bearing surface, and also to provide a method for manufacturing the bearing. SOLUTION: A surface except for the bearing surface 14a is covered with a resin film 20 by applying resin on an overall surface of a sintered body molded and sintered in a specified bearing shape by electrodeposition, removing the resin of the bearing surface 14a and thereafter, impregnating the lubricating oil L in the pores 10 from the bearing surface 14a from which the resin is removed. Thus, the oil impregnated sintered bearing in pores 10 of which the lubricating oil L is impregnated is provided. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a sliding bearing capable of maintaining excellent lubricating performance over a long period of time and exhibiting an excellent strength, and to provide a construction machine provided with the sliding bearing.SOLUTION: The sliding bearing has at least a bush 10 and a shaft part 20. The shaft part 20 includes a grease-feeding pathway 70 for feeding grease G to a sliding surface between the shaft part 20 and the bush 10 from the exterior, the bush 10 is formed from a porous sintered metal, and a decomposition catalyst S is adhered to the sliding surface of the bush 10. Consequently, the grease G can be easily fed to the sliding surface between the shaft part 20 and the bush 10 from the exterior via the grease-feeding pathway 70, at the same time, base oil of the fed grease G is separated by the decomposition catalyst S and permeates the bush 10 as it is, and is retained in voids C of the bush, so that the running out of lubricant is prevented and the excellent lubricating performance and excellent strength can be maintained over a long period of time.

摘要： The present invention is for providing an oil-impregnant sintered bearing (1), which can reliably preserve an oil film on a sliding face, and a method for manufacturing the oil-impregnant sintered bearing. An oil-impregnant sintered bearing is made by providing an internal diameter (4), which a rotating axis is inserted through, in a bearing main body (3), formed by a porous sintered alloy having internal pores therein, and providing a sliding face (5) in one region of the inner peripheral face (2) of the internal diameter, the sliding face (5) being obtained by closing the pores which have been opened in the inner peripheral face. The density in a section preserving oil pressure (6), which extends from the sliding face of the bearing main body toward the outer side of the diameter, is made higher than the density in other sections (7) of the bearing main body.
