Abstract
Official abstract text for this publication.
A bearing device includes a crankshaft having a plurality of journal portions, main bearings for supporting the crankshaft, and a bearing housing. The plurality of journal portions includes a first journal portion with a lubricating oil passage and a second journal portion without the lubricating oil passage. The first and second journal portions are supported by the first and second main bearings. The bearing housing includes an upper-side housing and a lower-side housing. A length of a crush relief of at least an upper-side halved bearing of the second main bearing is larger than a length of the crush relief of each of upper-side and lower-side halved bearings of the first main bearing.
