Bearing assembly for crankshaft at bearing part of reciprocating piston engine, has thrust ring arranged in axial direction of crankshaft, where thrust surface of crankshaft includes inner and outer grooves for guiding lubricant

摘要

The assembly has a thrust ring arranged in an axial direction (22) of a crankshaft (10) between a bearing part (18) and the crankshaft. The crankshaft is supported at the bearing part in a radial direction by a roller bearing. A thrust surface of the crankshaft includes inner and outer grooves for guiding lubricant i.e. lubricating oil, and is formed by a crank arm of the crankshaft. The grooves are completely formed in a peripheral direction (30) of the crankshaft. A channel of the bearing part is in fluid connection with the grooves over passage holes.
