Title:
SUPPORTING STRUCTURE OF CRANK SHAFT
Document Type and Number:
Japanese Patent JP2019007606
Kind Code:
A
Abstract:
To provide a supporting structure of a crank shaft capable of minimizing degradation of concentricity of bearings even when a temperature of an engine changes.SOLUTION: A supporting structure of a crank shaft for supporting the crank shaft having three or more journal portions, includes slide bearings for rotatably supporting the journal portions by semi-annular upper members 41a-41d positioned at an upper side and semi-annular lower members 42a-42d positioned at a lower side. End bearings as two slide bearings positioned at both ends among the slide bearings are constituted so that thermal deformation of the lower members 42a, 42d is more than thermal deformation of the upper members 41a, 41d.SELECTED DRAWING: Figure 6
