摘要： There is provided a method of working a plain bearing and a working apparatus of the plain bearing, which make it easy to perform working by forming a plurality of inclined surfaces of different angles in portions on both sides of the inner peripheral surface of the bearing alloy metal of the plain bearing in the axial direction thereof. In the working method and apparatus, a working holder 18 is provided which has a groove 20 extending on the inner peripheral surface in the peripheral direction and portions on both sides of the groove in the transverse direction formed in step-like shape, a half bearing 11 is housed in the working holder 18, and both ends of the half bearing 11 in the peripheral direction are pressed by use of pressing means 24. Then, the half bearing undergoes plastic deformation so as to be fitted into the groove and both sides of the half bearing in the axial direction thereof come into abutment with the edges 22, 23 of the step-like portions and are deformed in a polygonal line form. In this state, both ends of the half bearing 11 in the axial direction thereof are cut along one cylindrical surface by use of a broach 19. As a result, two inclined surfaces of different angles are continuously formed in the portions of both sides of the bearing alloy metal 13 of the half bearing in the axial direction thereof.

摘要： Disclosed is a sliding bearing in which a heat emission property of the sliding bearing is improved without affecting the original function of an overlay layer. An overlay layer is formed on a higher load-side bearing half, and extends circumferentially from a central portion thereof toward each of opposite ends thereof. Any overlay layer is not formed on a lower load-side bearing half, so that a bearing alloy remains exposed to the surface of this bearing half.

摘要： In a sliding bearing in which a bearing metal layer is covered with a coating layer, the coating layer comprises a thermosetting resin as a base resin and soft metal particles dispersed in the base resin in an amount of 0.1 to 10% by volume based on the volume of the coating layer. The soft metal is harder than the base resin and has a higher thermal conductivity than the base resin, so that the wear resistance and anti-seizure property of the sliding bearing are improved. In particular, when the soft metal particles are of copper, silver, tin, zinc or the like, the soft metal particles react with the sulfur contained in a lubricating oil to form a thin metal sulfide film excellent in lubricity on the surface of the particles, whereby the coefficient of friction is made smaller.
