Halved sliding bearing and method for producing same

摘要

A halved sliding bearing (1) has a recess (7) formed in a circumferential direction from an outer peripheral edge of a mating surface (5) of a semi-cylindrical bearing main body (3). To prevent formation of a burr to an inside of the recess (7) during formation of the mating surface (5), an entirety of at least one edge segment of a peripheral edge of the recess (7) opening on a circumferential end surface of a semi-cylindrical member (23) as an unprocessed body of the bearing main body (3), the at least one edge segment intersecting with an axial direction of the member (23), is chamfered. The mating surface is formed by cutting the circumferential end surface such that a cutting blade (31) firstly reaches the chamfered edge in the peripheral edge of the recess (7). Thus, the bearing main body is produced.

1. A method for manufacturing a semi-cylindrical halved sliding bearing, which has a recess formed in a circumferential direction from an outer peripheral edge of a mating surface of a bearing main body of the halved sliding bearing, the method comprising the steps of:
preparing a semi-cylindrical member as an unprocessed body of the bearing main body, wherein the recess opens on a circumferential end surface of the member, wherein at least one edge segment of a peripheral edge of the recess intersects with an axial direction of the member, and wherein an entirety of the at least one edge segment is chamfered; and forming the mating surface by cutting the circumferential end surface such that a cutting blade firstly reaches the chamfered edge segment in the peripheral edge of the recess, thereby producing the bearing main body.
