COMPARISON OF PROPULSION SHAFT STRAIGHTNESS USING NEW D.I.Y ARDUINO MEASUREMENT DEVICE WITH THE CONVENTIONAL DIAL INDICATOR

Abstract

In propulsion, shaft misalignment and bending are some of the essential topics discussed among industrialists. A marine propulsion shaft is often subjected to high stress and loading, which may lead to shaft bend—this causes the shaft to lose its straightness. Shaft straightness is a vital part of maintaining life other components. It is crucial to maintain its straightness and correctly identify such failure to avoid future misfortune. However, less study has been focusing on the technology development regarding shaft straightness tests. Therefore, this paper is a comparative study of a shaft straightness test using a newly developed measuring kit with the conventional dial indicator, which was typically used. The result of the study and analysis has been recorded and discussed
