    摘要: There is provided an oil-impregnated sintered bearing which enable to prevent oil leakage from an outer peripheral surface 7 of an bearing body 2. The oil-impregnated sintered bearing 1 includes a bearing body 2 which is made of a porous sintered alloy containing vacancies 8 and has a bearing hole 3 in which a rotary shaft can be inserted, wherein the vacancies 8 opened on an outer peripheral surface 7 of the bearing body 2 are crushed. The vacancies 8 may be crushed in the state of a green compact P, or in the state of a sintered alloy after sintering the green compact P. Consequently, the oil leakage from the outer peripheral surface 7 of the bearing 1 can be prevented, and oil pressure in the bearing hole 3 can be preserved.

    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: A high performance main bearing cap has particular surfaces densified for improved fatigue crack resistance. The surfaces densified are the bolted face (F) inside of a perimetral margin and outside of bold head interface areas around the main bolt holes (B), the surfaces of the main bolt holes and the side bolt hole threads (S). Preferred methods of densification are single needle programmable pattern peening of the bolted face peened area, over-burnishing of the bolt holes, and forming the threads rather than cutting them for the side bolt threads.

For the bearing arch portion (H), the machinability of the material (P) approximately matches the machinability of the bearing support structure (B) to which the bearing cap (A′) is assembled to produce a good quality bore and longer tool life during line boring. The bearing arch material (P) may be a bearing material.
