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).

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.

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...
