Help Your Laser Shaft Alignment System See!

| | |

By on November 13, 2014

For precision shaft alignment, nothing beats a good laser alignment tool. But the best of tools can have errors, or not even work at all, if the Sensors (detectors) can’t “see” the laser beams! We received a customer support call, and the aligner stated that his laser alignment tool wasn’t repeating. This is a rare […]

“Electrical Pipe Strain?”

| | | | |

By on November 6, 2014

Precision shaft alignment of rotating equipment is an essential part of any solid preventative maintenance program. To accommodate aligning any type of machinery you must be able to move one of the elements of the machine to achieve a precision shaft alignment. There are many limiting influences that could cause you to not be able […]

Setting up OL2R (Offline To Running) and Offset (Cardan) Brackets

| | | | |

By on October 29, 2014

OL2R Measurements (Offline To Running) are used to collect very accurate (and actual) Thermal Growth Values and Targets for critical rotating machinery. Offset Measurements (Cardan Shaft) are critical for offset drives to ensure there is no angular misalignment causing lead/lag issues with the drive shafts resulting in production related quality problems. Both the OL2R and […]

Uncoupled Shaft Alignment – It Doesn’t Need To Be Difficult.

| | | | |

By on October 13, 2014

The night before the OJT portion of a recent Fixturlaser GO Pro Training class, at a Combined Cycle Power Plant, the shim packs of the disc type coupling between a 3300 HP electric motor and fluid drive began to fail. The machine was shut down before any damage could occur and was waiting for our […]

Coupling Alignment Tolerances vs. Shaft Alignment Tolerances

| | | |

By on October 8, 2014

A coupling alignment tolerance and a shaft alignment tolerance are different things – VERY different things! A Coupling Alignment Tolerance is often (but not always) the maximum amount of misalignment the coupling will operate at before premature failure. A Shaft Alignment Tolerance is the maximum amount of misalignment the shafts can tolerate before they begin […]

By on October 2, 2014

Many of our classroom discussion topics relate to problems in the field when attempting a precision shaft alignment of rotating equipment. One such topic is how to move a piece of equipment horizontally that does not have jack bolts already mounted on the base. The obvious answer is to mount a set of jack bolts […]

Machine Train Shaft Alignment Tricks

| | |

By on September 10, 2014

Simply stated, a machine train is when three or more machine components are coupled together, acting as one.  Machine train alignment can sometimes be a complicated task. Some laser alignment tools can measure machine trains of up to several machines, simplifying the move options.  Whether you have a machine train program or not, by using […]
