摘要： A sintered oilless kinetic pressure bearing containing an oil is formed with a plurality of grooves along the inner diameter to produce the kinetic pressure, in which the proportion between the groove and corresponding inner periphery portion is appropriately maintained according to the Reynolds equation for decreasing initial abrasion and heightening durability to lengthen the life while a pressure is induced throughout the inner periphery for providing a stiffness coefficient impervious to a great impact or high load imposed by an external force and heightening stability in the rotating motion. The bearing in a cylindrical sintered oilless bearing includes a plurality of grooves along the inner periphery plane thereof in the lengthwise direction of a shaft such that an interval between the grooves become respective inner periphery portions and the groove and inner periphery portion are partitioned by side planes. Thus, assuming that an angle range of the groove is denoted by .alpha. and an angle range of the inner periphery portion is by .beta..

摘要： A method for fabricating a sintered oilless bearing using a correcting rod having a projection correcting portion and a groove forming portion having outer diameters respectively identical to inner diameters of projections and grooves to be formed into the oilless bearing. An upper punch is inserted into the upper portion of the correcting rod for pressing the sintered oilless bearing to allow the inner periphery of the sintered oilless bearing to closely contact the groove forming portion and, simultaneously, fit into the projection forming portion. A lower punch is ascended from the lower portion of the correcting rod for separating the sintered oilless bearing from the correcting rod and to allow a portion of the inner periphery of the sintered oilless bearing inserted into the projection forming portion to match with the outer periphery of the projection correcting portion while being compressed, thereby exactly matching the concentricities of the projections and grooves of the sintered oilless bearing to make the kinetic pressure generating force consistent and improve a bearing force.
