    • A bearing arrangement including a plain bearing consisting of a laminated body of a bearing layer and a backing metal supporting the bearing layer. The backing metal is made of a material whose modulus of elasticity is lowered by cold working (austenitic stainless steel), and the bearing layer and the backing metal are joined to each other by cold rolling. Since a working proportion of the backing metal upon the above-mentioned cold rolling is small in the inside portion held in contact with the bearing layer but is large in the outside portion, the modulus of elasticity of the backing metal is different between the inside portion and the outside portion thereof, and the modulus of elasticity in the outside portion is smaller than the modulus of elasticity in the inside portion. Also, the hardness of the outside portion is higher than the hardness of the inside portion. The above-mentioned plain bearing is of half-split type or wrapped bush type, and it is interposed between a bearing housing of the type that two halves are coupled together by means of bolts and a rotary shaft to be supported with a predetermined interference.
    • 一种轴承装置,包括由轴承层的层叠体和支撑轴承层的背衬金属构成的滑动轴承。 背衬金属由通过冷加工(奥氏体不锈钢)降低弹性模量的材料制成,并且轴承层和背衬金属通过冷轧彼此接合。 由于在上述冷轧时的背衬金属的工作比例在与轴承层保持接触的内侧部分小,而在外侧部分较大,因此背衬金属的弹性模量在内部 外侧部分和外侧部分的弹性模量小于内侧部分的弹性模量。 此外,外侧部分的硬度高于内侧部分的硬度。 上述滑动轴承是半分体式或者套管式的,并且它被插入在两个半部通过螺栓联接在一起的轴承壳体和以预定的干涉被支撑的旋转轴之间。

    • An internal gear pump includes a casing, a cover mounted to the casing, a pump chamber defined between the casing and the cover, an internal gear slidably arranged within the pump chamber, an external gear rotatably arranged within the pump chamber and rotatingly driven from the outside to engage with and drive the internal gear, a fixed filler for regulating sliding movements of the internal and external gears and for preventing oil leakage from a high-pressure side to a lower-pressure side within the pump chamber, a suction port formed in the cover and extended circumferentially within the angular range of about 90 degrees, an oil pocket device formed in respective sliding surfaces of the casing and cover, on which the opposite side surfaces of the internal gear slide, the oil pocket device having a plurality of taper lands extended within the radial width of from the root of tooth of the internal gear to the outer peripheral surface of the internal gear between the peripheral wall of the pump chamber and the fixed filler, the bottom surface of each of the taper lands being tapered to become gradually shallow in the rotating direction of the internal gear, thereby producing a wedge film pressure between the opposite side surfaces of the internal gear and the respective sliding surfaces of the casing and the cover.
