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： There is disclosed a half thrust bearing of a substantially semi-circular shape. A thrust relieve 22, slanting toward a confronting end of the half thrust bearing progressively away from a bearing surface of a half thrust bearing, is formed at each of circumferentially-spaced opposite end portions of the bearing surface by pressing (cold forging), so that those portions of the bearing surface, disposed adjacent respectively to the thrust relieves 22, are higher in strength than the other portions of the bearing surface. With this construction, even if a thrust collar of a crankshaft abuts against localized portions of the bearing surface disposed adjacent to the thrust relieves 22, a bearing alloy will not subjected to premature fatigue and separation.

摘要： There are provided a plain bearing which is excellent in oil retaining property and wear-resistant property. The plain bearing has a number of fine grooves which are parallely formed with one another and extending in the circumferential direction on the inner surface of the bearing, the fine grooves comprising deep grooves and shallow grooves. When this bearing is used as a plain bearing, a large amount of lubricating oil can be retained in the deep grooves and the shallow grooves so that a plain bearing which is excellent in anti-seizure property and wear-resistant property can be obtained. Further, even if the shallow grooves will have been worn out by wear and tear during use of extended period of time, the anti-seizure property and the wear-resistant property can be stably maintained by the lubricating oil retained in the deep grooves.

摘要： A main-load side bearing metal piece on which a heavy load is imposed is coated on an inner surface thereof with a thin overlay having a uniform thickness. Meanwhile, a non-load side bearing metal piece is coated on an inner surface thereof with an overlay having a uniform thickness greater than that of the overlay formed on the inner surface of the main-load side bearing metal piece. With this construction, the bearing metal piece shows excellent load carrying capacity and fatigue resistance because the overlay formed on the inner surface thereof is thin, while the non-load side bearing metal piece shows excellent foreign matter embeddability and conformability because the overlay formed on the inner surface thereof is thick. Moreover, since there are formed the overlays each having a uniform thickness in respective inner surfaces of each of the bearing metal pieces, and therefore it is possible to reduce the manufacturing cost.
