Bearing structure for multi-link-type piston crank mechanism for internal combustion engines

A crankshaft bearing (11) has a pair of main bearing metals (41), and lubricating oil is guided from an oil gallery to an inner circumferential oil groove (43) through an oil passage (33) in the block and a first oil hole (42). Some of the lubricating oil is supplied to a control shaft bearing (17)...

Beschreibung
Zusammenfassung:	A crankshaft bearing (11) has a pair of main bearing metals (41), and lubricating oil is guided from an oil gallery to an inner circumferential oil groove (43) through an oil passage (33) in the block and a first oil hole (42). Some of the lubricating oil is supplied to a control shaft bearing (17) via a second oil hole (44) and an oil passage (34) in the cap. Lubricating oil is guided from a third oil hole (46) in a pair of control shaft bearing metals (45) to an inner circumferential oil groove (47). The oil groove (43) in the crankshaft bearing (11) functions as an oil channel for supplying lubricating oil to the control shaft bearing (17), thereby achieving a simple configuration.
