What is the recommended procedure for conducting a shaft alignment?

The recommended procedure for conducting a shaft alignment involves performing a soft foot check, measuring misalignment, adjusting the machine, and then re-measuring. This approach ensures that all critical aspects of alignment are addressed systematically.

Starting with a soft foot check is vital because it identifies if there are any unevenness or flex within the machine base that could lead to misalignment. Following this, measuring the misalignment provides a baseline that indicates how much adjustment is required. The adjustment phase is crucial for bringing the shafts into the correct alignment position, which can significantly affect machine performance and longevity. Finally, re-measuring after adjustments allows for confirmation that the alignment is now within acceptable tolerances. This thorough process helps to ensure that any potential issues contributing to vibrations, wear, or failure are addressed effectively.

In contrast, measuring only after adjustments neglects the need to verify alignment before making changes, while starting by adjusting the machine without prior measurement could lead to incorrect adjustments. Relying solely on visual inspections is insufficient, as they cannot provide the precise measurements necessary to ensure proper alignment, which can only be achieved through a systematic approach involving accurate measurement before and after adjustments.
