摘要

The arrangement (10) has a lubricant channel (24) partially extending into a shaft extension (16) and into a crank pin (20). A connecting rod bearing point (23) is supplied with a lubricant i.e. oil, through the lubricant channel. Another lubricant channel (26) extends into a crank cheek (22) and fluidly connected to the former lubricant channel. The lubricant channel comprises an outlet opening (30) for the lubricant on a side of a front end (28) of the crank cheek, where the front end faces towards a bearing element i.e. rolling bearing (18), in an axial direction.
