Embodiment Construction

[0020] Next, embodiments of the present invention will be described. Notice, figure 1 is a front view of the sliding bearing 1, upward and downward in the drawings are considered as up-down directions, and front and rear directions in the drawings are considered axial directions (front-rear directions).

[0021] First, refer to figure 1 and figure 2 The half-body member 2 constituting the sliding bearing 1 according to the invention is described.

[0022] Sliding bearings 1 are cylindrical members and are suitable for applications such as figure 1 The plain bearing structure for the crankshaft 11 of the engine shown in . The plain bearing 1 is composed of two half-parts 2 . The two half-body members 2 are shaped into sections obtained by dividing a cylinder into two along a line parallel to the axial direction, and the half-body members 2 have a semicircular cross-section. In this embodiment, the half-body components 2 are arranged vertically, and their mating surfac...

Abstract

The present invention addresses the problem of providing a sliding bearing with which it is possible to obtain a friction reducing effect and to suppress the total quantity of outflow oil. Provided is a manufacturing method for a sliding bearing (1) comprising vertically-arranged half members (2), (2) that are obtained by halving a cylinder in parallel with the axial direction and that have a metal layer (21) and a lining layer (22), which is provided to the inner peripheral surface of the metal layer (21). The manufacturing method has a thin groove forming step (S30) (first step) in which a thin groove (3) is provided circumferentially to the axial direction end of the lower half member (2) at the downstream side of the rotational direction. During the thin groove forming step (S30), the depth (d) of the thin groove (3) is formed so as to be shorter than the length obtained by subtracting, from the thickness (h1) of the lining layer (22), the sum of the tolerance (a1) of the thickness of the lining layer (22) and the tolerance (a2) of the depth of the thin groove (3).

Description

technical field [0001] The present invention relates to the technology related to the method of manufacturing a sliding bearing, and to the technology related to the method of manufacturing a sliding bearing in which a cylinder is obtained by dividing a cylinder into two parts along a line parallel to the axial direction. The half-body components are arranged vertically. Background technique [0002] In general, a sliding bearing having a half-split structure is known as a bearing for supporting a crankshaft of an engine, in which two members obtained by dividing a cylinder are arranged together, but there is High friction problem. In view of this, there is known a bearing in which a clearance portion (groove) is formed on the entire outer circumference of each of both axial end portions of the bearing (for example, see Patent Document 1).
