21 Jan 2009 It is really tough job to take crankshaft deflections in the engine room but even after all that hard work, the results will not be satisfactory if you do not know how to make the best use of the acquired readings. Hence this article explains the concept of deflection curve and the process of analysis of deflection
Below picture shows the main components of the crank shaft. Crankshaft Deflection: The crankshaft of the marine diesel engine is a huge bulky component which should remain as straight as possible during operation, otherwise it could lead to serious damage to the engine and the
13 Oct 2017 Full-text (PDF) | In order to establish the proper functioning of a marine diesel engine, respectively the crankshaft bearing condition and uniformity of thermal processes taking place in each cylinder, a study was made over the crankshaft of a MAN B&W 7K80 MC-C engine, over a period of about four
To ensure efficient and reliable operation the crankshaft should be checked periodically for alignment by measuring the deflection of the webs. The main bearing shells are made steel with a lining bearing metal which can be white metal, copper-lead aluminium-tin alloy. A thin flash of lead or indium is often added

Foundations under reciprocating equipment will often deteriorate over time. When this happens, and the foundation subsides, the web deflections in the machinery crankshafts can go beyond. OEM specifications. In the limit, excessive web deflections can cause crankshaft fatigue failures. A common approach to restoring

11 Mar 2016 At some time in his career the Diagnostic Engineer will find knowing about engine crankshaft deflection measurement of use. This article will help.
The crankshaft warpage or run-out journal, the analysis of the crank web deflection are also evaluated and presented in this paper. Keywords: crankshaft failure, deformation, misalignment, taper, crank web deflection. INTRODUCTION. Transportation is a very important factor in the economy of every country, as every
