Title:
CONNECTING ROD BEARING AND BEARING DEVICE
Document Type and Number:
Japanese Patent JP2018179164
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a connecting rod bearing and bearing device of an internal combustion engine, where cavitation erosion does not occur on a slide layer even in a case where a cavity occurs in lubricant.SOLUTION: A connecting rod bearing has a first half-split bearing and a second half-split bearing. The second half-split bearing has an oil groove over the entire length in a circumferential direction. The first half-split bearing has a first partial groove and a second partial groove. The oil groove and the first and second partial grooves communicate with each other. A cylindrical recess part communicating with a circumferential center part side end part of the first partial groove is formed. An axial line of the cylindrical recess part extends toward an axial line of the first half-split bearing. An inner diameter of the cylindrical recess part is 100%-150% of a width in the axial direction of the first partial groove. A depth of the first partial groove at a position of communicating with the cylindrical recess part is more than a thickness of a slide layer of the first half-split bearing. The cylindrical recess part is formed so as to have a depth deeper than the depth of the first partial groove at the position of communicating with the cylindrical recess part, and so as not to penetrate to a bearing outer peripheral surface of the first half-split bearing.SELECTED DRAWING: Figure 2
