Solving a Base Bound Problem (21 KB)

Summary
In a base bound situation the movable machine (Motor) is sitting high, but there are no shims under the feet. The problem can be solved by raising the front of the stationary machine (Pump).

Understanding Angular Misalignment (16KB)

Summary
This tech note from VibrAlign explains the often misunderstood concept of shaft centerline angularity. Easy to understand graphics show in layman's terms how angularity relates to the slope relationship of shaft centerlines.

Rough Alignment Procedure (33KB)

Summary
Rough alignment is one of the recommended pre-alignment procedures. A straightedge is suitable for the horizontal rough alignment. But to expedite the vertical rough alignment it is recommended that one not make guesses about the amount to shim. This procedure provides an easy method for calculating the amount to shim...

Understanding face dial indicator readings and angularity (31KB)

Summary
This tech note from VibrAlign explains how the face readings (when using the rim and face method) relates to the shaft angularity. Easy to understand graphics show in layman's terms how the "gap" measurement is used to determine the angularity.

Understanding Offset Misalignment (16KB)

Summary
Besides angularity, the offset misalignment is used to determine the quality of the alignment. This tech note from VibrAlign explains the concept of "shaft offset" as well as the very important "offset misalignment" Colorfully illustrated for easy understanding.

Understanding rim dial indicator readings and offset misalignment (31KB)

Summary
This tech note from VibrAlign explains how the rim readings (when using the rim and face method) relates to the shaft offset misalignment. Easy to understand graphics show in layman's terms how the rim reading is used to determine the offset misalignment.

Accurately Measuring Machinery Movement (2.1MB)

Summary
All machinery moves as they go from off-line to on-line. Most of this movement is usually attributed to thermal growth but in fact restraining points and process forces can contribute significantly to these changes as well. This presentation will explore the phenomena of dynamic movement and how to properly measure the total movement of machines in order to perform true precision alignment.

New laser technique for measuring dynamic movement (1.4MB)

Summary
Laser shaft alignment was introduced over a decade ago. Since then there have been incremental improvements to laser shaft alignment systems. The OL2R Fixtures represent the most profound innovation in the field of precision alignment since the introduction of laser alignment. The OL2R Fixtures (patent pending) employ virtual centerlines to precisely measure the total movement of machinery.
