Embodiment Construction

[0022] Next, embodiments of the invention will be described. It should be noted, figure 1 It is a front view of the slide bearing 1 , where the up and down of the screen is defined as an up and down direction, and the front and rear directions of the screen are defined as axial directions (front and rear directions).

[0023] First, use figure 1 as well as figure 2 The split member 2 constituting the sliding bearing 1 according to the embodiment of the present invention will be described.

[0024] Such as figure 1 As shown, the sliding bearing 1 is a cylindrical member, and is applied to the sliding bearing structure of the crankshaft 11 of the engine. The slide bearing 1 is composed of two split components 2,2. The two split members 2, 2 have a shape obtained by bisecting a cylinder parallel to the axial direction, and are formed in a semicircular cross section. In this embodiment, the split members 2, 2 are arranged up and down, and joint surfaces are arranged on the ...

Abstract

The present invention relates to a slide bearing (1) in which half members (2, 2) obtained by bisecting a cylinder in parallel to the axial direction are arranged vertically, wherein: in an axial-direction end section of the lower half member (2), a narrow groove (3) is provided along the circumferential direction on the downstream side in the rotating direction; a circumferential edge section (2a) formed so as to be lower than the surface that abuts against a crankshaft (11) is provided on the outer side of the narrow groove 3 in the axial direction; and in a cross-sectional view orthogonal to the length direction of the narrow groove (3), the bottom surface (3a) of the narrow groove (3) is formed in a curved manner. Thus, the present invention can achieve a friction-reducing effect and also suppress the total amount of effluent oil.

Description

technical field [0001] The present invention relates to a technology of a sliding bearing, and relates to a technology of a sliding bearing in which half members formed by bisecting a cylinder parallel to the axial direction are arranged up and down. Background technique [0002] Conventionally, as a bearing for supporting the crankshaft of an engine, a sliding bearing having a split structure in which two members bisected in a cylindrical shape are joined is known, but since oil has a high viscosity in a cold state , so there is a problem of large friction. Therefore, there is known a bearing in which oil grooves (thin grooves) are formed on both ends of the bearing in the axial direction over the entire circumference (for example, refer to Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese PCT Publication No. 2003-532036 Contents of the invention [0006] The problem to be solved by the invention [0007]...
