| Abstract:The design scheme for supplying lubricating oil from the crankshaft to the intermediate coupling of a certain type of diesel engine used in land gensets is introduced.Based on the design scheme，the design key points of the crankshaft fuel supply system were proposed from the aspects of the crankshaft holes size and positioning，the inlet and outlet oil flow directions of the fuel supply system，etc.Finite element analysis was conducted on the stress concentration in the crankshaft oil hole to verify the reliability of the lubricating oil supply scheme.Compared with the intermediate shaft oil supply system，the crankshaft oil supply system has certain advantages in production cycle，manufacturing cost，and technical requirements. |
