Title:
OIL-IMPREGNATED SINTERED BEARING
Document Type and Number:
WIPO Patent Application WO/2004/113747
Kind Code:
A1
Abstract:
An oil-impregnated sintered bearing has, for a longer operating life, a large storage amount of lubrication oil as a bearing element and less consumption of the oil by scattering. Additionally, the bearing has a simple structure and requires less space. The bearing is made by combining porous sintered members and joining them by sizing. The bearing has a cavity near the bearing center, at a portion where constituting members oppose to one another. A gap having a smaller width than the cavity is opened from the cavity along an opposing face of a constituting member to an end face or the outer periphery of the bearing.
