Back Off Jack Bolts for Improved Alignment Results

| | | | |

By on December 14, 2016

Millwrights and mechanics know the benefits of using jack bolts to precisely control the horizontal position of the movable machine when performing a precision shaft alignment. However, we also see the tendency to tighten the jack bolts, on both sides of the movable machine, either before or after tightening the hold down bolts. Tightening jack […]

Base Bound Machinery Corrections

| | | | |

By on December 2, 2016

Most aligners are familiar with a bolt bound situation, which occurs when the motor cannot be moved enough to achieve proper horizontal alignment.  A base bound condition occurs when a motor cannot be lowered sufficiently to achieve proper vertical alignment.  Here is an example.  During a customer’s recent pump replacement, the motor was left in […]

Determining Cold Alignment Targets from OEM Dial Indicator Specifications

| | | | |

By on November 23, 2016

A client was aligning a motor-compressor set and wanted to use the OEM specifications for thermal growth (OL2R) compensation. The manual gave the target values as rim and face dial indicator numbers for either the motor hub or compressor hub. In this case the motor hub specifications were used. He was using the Fixturlaser NXA […]

Other Influences to Precision Shaft Alignment Results

| | | | | |

By on November 9, 2016

Over the years we have fielded several technical support calls from maintenance personnel having repeatability and soft foot issues (during an alignment) all of which had a common issue; other influences. Meaning not the typical looseness, coupling backlash, soft foot issues. During the “heat of the battle” to get the precision shaft alignment job finished […]

Cooling Tower Alignment

| | | |

By on November 4, 2016

Performing Precision Shaft Alignments on Cooling Towers present a unique set of challenges. A recent job is typical of what I find. We were originally called out because on three cooling towers the motors were experiencing high vibration. Some of the challenges include: 1 – Access through shrouds 2 – Ladders often required to gain […]

Fudging Your Shims? Go The Same Direction.

| | | | |

By on September 22, 2016

When performing a precision laser shaft alignment, it is best to add or remove shims exactly as the display unit indicates.  There are circumstances when this may not be possible due to your assortment of shims, or when you want to “fudge” your shims slightly to keep the total number of shims low. (Clink for […]

MACHINERY VIBRATION PROBLEMS AND SOLUTIONS, PART 6 – RESONANCE

| |

By on September 15, 2016

Resonance is when a force causes an object to “resonate”, due to excitation of its natural frequency.  Think of a machine coasting down to a stop.  There are certain speeds in coasting down that excite natural frequencies of the machine components.  This is often observed in the coast down of a bench grinder.  As the […]
