Why Don’t I Input a Coupling Diameter?
We often get asked why we don’t input a coupling diameter when performing a precision shaft alignment with the ACOEM laser alignment systems. The coupling diameter (or more correctly sweep of a face dial indicator) is only required when doing a rim and face dial indicator alignment or when the user wants to know the…Read More
Setting Tolerances in Fixturlaser Shaft Alignment Tools
Fixturlaser Shaft Alignment Tools come pre-programmed with generally accepted industry tolerances for electric motor driven machinery. These tolerances are based on the motor RPM and will give you an “endpoint” in the alignment process (based on the measured offset and angular misalignment at the center point of the coupling in both the vertical and horizontal…Read More
Converting Dial Indicator Cold Alignment Targets with the Fixturlaser NXA
Even though laser shaft alignment systems have been in use for over 3 decades some industries have alignment tolerances and cold alignment targets in dial indicator terms or language. Take for instance the gas compression and processing industry. Many OEM’s, packagers, end users, and service companies use laser alignment systems, however their cold alignment targets…Read More
Dial Indicator Alignment – Bar Sag Still Exists in 2018!
And it just may be a lot more than you would think. While visiting a customer site to do an alignment check using the EVO laser alignment tool on a 1750 HP Electric Motor / Boiler Feed Water Pump / 3574 rpm, measurements were taken several times (x3) to make sure the values were repeatable. …Read More
The Language of Alignment
Rim & Face, Angle & Offset, Parallel & Angular Deviation, Parallel Offset, thousands of inch and mils! What does it all mean? Actually it’s pretty much the same thing, though not exactly. I’ve been a VibrAlign Technical Trainer since 2008 with training classes in a variety of industries and with students previously using other methods…Read More
Converting Laser Alignment System Readings to Rim and Face Dial Readings
VibrAlign released the free Laser-Dials App to aid laser system users who need/want to convert their laser shaft alignment system results to rim and face dial indicator readings. You can also use the App to convert dial indicator readings to laser readings. Most are interested in converting laser results to dials so that is what…Read More
Defining Angularity in Shaft Alignment
There are only two types of measurements for shaft misalignment – offset, which may be called parallel or rim, and angularity, which is sometimes called slope, or face. Offset (parallel or rim) is easy to understand. One shaft is simply higher, lower, or to the left or right of the other one. But angularity can…Read More
