摘要： PURPOSE: To maintain annular strength against high pressure and an oil content adequate for good lubrication, by prescribing the alloy composition of each of an inner layer, which constitutes the sliding surface of an oil-containing bearing, and an outer layer, which constitutes the body of the bearing, to sinter both the layers integrally with each other to completely conjoin them together.
CONSTITUTION: An inner layer, which constitutes the sliding surface of a bearing, is made of a copper alloy comprising 8 to 10% of tin and the rest of copper and unavoidable impurities. An outer layer, which constitutes the body of the bearing, is made of an iron alloy comprising 0.75W9% of copper, 0.5W6% of tin and the rest of iron and unavoidable impurities. Since the powdery metals as the materials for the inner and the outer layers are similar to each other in bulk and fluidity and in dimensional change at sintering, the powdery materials for both the layers are completely sintered and conjoined to each other so that a bearing which has high strength and has no wrong bonding and cracks and whose two-layer oil contents are maintained is provided.

摘要翻译：目的：通过规定构成含油轴承的滑动面的内层和构成外层的外层的各层的合金组成，为了保持高强度的环状强度和适于良好润滑的油含量轴承的主体，将两个层彼此一体地烧结以将它们完全结合在一起。构成：构成轴承滑动面的内层由铜合金制成，该铜合金包含8-10％的锡，其余的铜和不可避免的杂质。构成轴承主体的外层由含有0.75-9％的铜，0.5-6％的锡和其余的铁以及不可避免的杂质的铁合金制成。由于作为内层和外层的材料的粉末状金属在本体和流动性以及烧结中的尺寸变化方面彼此相似，所以两层的粉末状材料完全烧结并结合在一起，具有高强度并且没有错误的粘合和裂纹，并且其两层油含量被保持。
