Geometric Tolerance Applications and Analysis Method in Rotational Mechanical Components

Abstract

This paper focus a review on geometrical tolerance application and effects in rotational mechanical components. In today’s rapid competition on pump and turbomachinery industry the geometrical tolerancing process plays a significant role in high rotational speed of shaft. The imbalance force and misalignment of the shaft during rotating is the cause of the system's vibration. Therefore, Geometrical Dimensioning and Tolerance (GD&T) has been considered as an essential requirement to be fulfilled by rotating machinery manufacturers and assembly worker. The impact and the level of damage to critical parts of the machine were reviewed as a benchmark for further study to reduce the problem and improve the life time component. As a result, there are extensive researches such as optimisation of tolerance for mechanical components in rotating machinery.
