A crank pin, also known as a connecting rod journal, is the part of a crankshaft that connects to the piston rod and rotates in the bearing. In a 4 stroke engine, the crankpin undergoes four phases of motion: intake, compression, power and exhaust. During these phases, the crankpin is subjected to various forces and […]
Crankshaft for marine diesel engines have been discussed in this article. They are of many types and is used as per the need for a particular type of requirement. After piston takes away the combustion forces developed during ignition, it transmits forces to crankshaft, and gives it a circular cyclic motion. The shaft and the […]
This article discusses about the crankshaft deflection and bearing clearance measurement in details. Both of the process is crucial for the any engine onboard. But here we will focus our approach towards the main engine only. But for crankshaft deflection related to generators is more or less same. Read this interesting article: Main engine crankcase […]
