How is angularity typically measured in machinery alignment?

Angularity in machinery alignment refers to the degree of misalignment between the axes of rotating machinery components, which can lead to excessive wear and reduced efficiency. The most effective way to measure angularity is by assessing the rise over run, especially at critical connection points like the shaft or coupling gap. This approach provides a clear understanding of the angle formed due to misalignment.

Using rise and run as a measurement method helps to quantify the angular relationship between two components. By measuring the vertical displacement (rise) relative to the horizontal distance (run), operators can determine how much adjustment is needed to achieve proper alignment. This method is essential in alignment procedures, enabling the identification of imbalances that can cause operational issues.

Other methods mentioned, such as measuring elevation/depth at the machine base or width/height at the edges, do not specifically address the angular misalignment between elements, which is the primary focus of angularity assessment. Similarly, angle/diameter measurements at the coupling section do not tailor to the direct relationship of rise over run, making this approach less practical for precise angularity determination.
