    • PURPOSE: An abrasion resistant sliding bearing is provided to achieve improved load-carrying capacity by improving lubrication, abrasion resistance and surface fatigue resistance of an inner sintered bearing layer of bearing. CONSTITUTION: A sliding bearing comprises a steel-back metal; a sintered metal layer(5) bonded to the steel-back metal, and which consists of 10 to 30 weight percent of copper, 0.1 to 5.0 weight percent of nickel, 0.1 to 8.0 weight percent of chrome and remainder of iron; and a dry lubrication agent contained in the sintered metal layer. The dry lubrication agent is one of 0.1 to 6.5 weight percent of graphite or 0.1 to 7.0 weight percent of molybdenum disulfide. The sintered metal layer has a ring type groove(9) which is formed by cutting away a portion of the sintered metal layer so as to store grease in the ring type groove.
    • 目的:提供耐磨滑动轴承,通过提高轴承内部烧结轴承层的润滑,耐磨性和耐表面疲劳性来提高承载能力。 构成:滑动轴承包括钢背金属; 与钢背金属结合的烧结金属层(5),其由10〜30重量%的铜,0.1〜5.0重量%的镍,0.1〜8.0重量%的铬和余量的铁构成。 和包含在烧结金属层中的干燥润滑剂。 干润滑剂是0.1至6.5重量百分数的石墨或0.1至7.0重量%的二硫化钼之一。 烧结金属层具有通过切除烧结金属层的一部分而形成的环形槽(9),以便在环形槽中存储润滑脂。
