BEARING CAP
Document Type and Number:
WIPO Patent Application WO/2015/156025
Kind Code:
A1
Abstract:
A bearing cap (10) rotatably supports a crankshaft (4) by being fastened to a bulkhead (2) of a cylinder block (1) by the use of a securing bolt (3), and is cast by pouring an iron frame (20) comprising an iron-based metal into a light metal alloy. A concavity (22) recessed radially outward from the inner peripheral surface is formed in a frame body (21) of the iron frame (20) which constitutes a half cylinder concentric with a bearing surface (12) rotatably supporting the crankshaft (4). The radial depth of this concavity (22) is set longer than the peripheral width relative to the bearing surface.
