Abstract
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.
