ない。(Problem to be solved by the invention) Among these conventional metal bearings, those with oil grooves on the bearing surface have a reduced bearing area, which increases surface pressure on the bearing surface and reduces seizure resistance. Therefore, it cannot be applied to high-output engines.
また、軸受面に焼結材からなる油溜りを設けたものは、

材の結晶粒が肥大し、耐疲労性が低下する。In addition, bearings with an oil reservoir made of sintered material on the bearing surface,
Although the surface pressure on the bearing surface does not increase, there is a risk that the inserted sintered material will fall off when the sintered material is inserted.
Furthermore, in the case of sintering in a heating furnace, the crystal grains of the base material of the metal bearing become enlarged, resulting in a decrease in fatigue resistance.

のである。The present invention has been made in view of the above points, and provides an oil reservoir made of sintered material on the bearing surface without reducing fatigue resistance, and since the oil reservoir is firmly joined, there is no risk of it falling off. The present invention aims to provide a method for manufacturing metal bearings that is free of metal bearings.
