Abstract
Official abstract text for this publication.
The bearing apparatus 1 includes a crankshaft having multiple journals, main bearings supporting the crankshaft, and a bearing housing. The plurality of journals include a first journal with a lubricating oil passage and a second journal without a lubricating oil passage. The first and second journals are supported by first and second main bearings, respectively. The bearing housing is constituted by an Al-alloy upper housing and an Fe-alloy lower housing. The depth of the oil groove of the upper half bearing of the second main bearing at least in a ±45° region is equal to or smaller than a half of the depth of the oil groove of the upper half bearing of the first main bearing in the ±45° region.
