摘要： A half bearing constituting a cylindrical plain bearing for supporting a shaft for rotation when two of the half bearings are combined together. The half bearing has two circumferential ends each of which has a plurality of circumferential grooves without formation of any crush relief surface. The grooves extend substantially over an overall circumferential dimension of the half bearing and include portions located at both circumferential ends of the half bearing respectively. Each portion has a larger axially sectional area than the grooves formed in a portion of the half bearing mainly subjected to load during rotation of the shaft.

摘要： 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.

摘要： There is provided a sliding bearing, which can continuously enhance conformability even when deformation by high oil film pressure in the vicinity of a central part of the sliding bearing occurs. The sliding bearing includes crownings which are each formed in an inclined shape toward an outer peripheral surface from an inner peripheral surface, at end parts in an axial direction, of an inner peripheral surface of a sliding bearing, so that even when the region in the vicinity of the central part of the sliding bearing 1 receives the oil film pressure and deforms in the recessed shape so as for both the end parts in the axial direction to locally contact a shaft, conformability can be enhanced not only at an early stage of use of the sliding bearing but also continuously by relief by the crownings.
