Embodiment Construction

[0020] 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).

[0021] 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.

[0022] 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

Provided is a sliding bearing capable of achieving a friction reduction effect and limiting a total outflow oil amount. This sliding bearing (1) has vertically disposed halved members (2),(2) which are formed by halving a cylinder in the direction parallel to the axial direction of the cylinder, wherein narrow grooves (3) are provided on an axial end of the lower halved member (2) in a circumferential direction on the downstream side in the rotation direction; peripheral sections (2a) are formed outward from the narrow grooves (3) in the axial direction so as to be lower than a contact surface between the sliding bearing (1) and a crankshaft (11); and, when viewed in a cross-section perpendicular to the longitudinal direction of the peripheral section (2a), a chamfered section (2b) is formed at an outer edge section in the axial direction of the peripheral section (2a).

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, a bearing is known in which oil grooves (thin grooves) are formed at both ends in the axial direction of the bearing (see, for example, 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] However, in conventional bearings forme...
