Kontrollera dina shims före uppriktning! 👍
Har du någonsin lagt till antalet shims som ditt uppriktningsverktyg säger att du ska göra bara för att upptäcka att din maskin fortfarande inte är korrekt? Detta är en frustrerande men vanlig förekomst. Var det ett beräkningsfel eller gav ditt axeluppriktningsverktyg dig fel information? Mer än troligt är dina shims är skyldiga.

Why Don’t I Input a Coupling Diameter?
Tolerances for shaft alignment are typically expressed in terms of angle and offset. It is common knowledge that offsets cause confusion, but angularity often confuses those tasked with aligning or verifying alignments.
-
Understanding the Need for Offset Shaft Alignment
There are two parts that must be understood, proper phasing and angularity of the input and output shafts.

The Maintenance Supervisors 5 Questions
These are the five questions every maintenance supervisor needs to answer.

Coupling Tolerances vs. Shaft Alignment Tolerances, revisited
There were huge differences between coupling alignment tolerances and precision shaft alignment tolerances during a recent Acoem RT-300 training class. Electric motors and centrifugal pumps fitted with grid couplings of model 1070T were aligned at 1800 RPM. A contractor performed the initial alignment on this fairly new installation.

Phase Analysis for Confirmation of Machine Faults
Verifying your machines' issues using phase analysis can be a very effective method of verifying faults discovered during an inspection. Vibration programs can be made more effective when phase, particularly cross-channel phase analysis, is applied properly.

Aligned at the Factory – Realigned in the Field
When using a straightedge to perform a shaft alignment you won’t see angular misalignment.
-
What is Machine Misalignment Costing You?
To calculate the cost of misalignment, first determine the cost of the machine’s downtime.
-
Coupling Tolerances vs. Shaft Alignment Tolerances, revisited
We have several times discussed the differences between coupling alignment tolerances and precision shaft alignment tolerances. As stated in those text the coupling manufacture’s tolerances are for the coupling. As maintenance professionals we are concerned with the coupling, however we are more concerned with the bearings in the machines.

Which Maintenance Program is Right for My Facility?
Predictive maintenance involves scheduled testing on regular intervals.

Don’t Forget a Lift Check!
​A lift check isn’t always done when performing a precision shaft alignment, nonetheless excessive lift can be the cause of alignment frustration.

Laser Kit Tips
The FIXTURLASER Laser Kit consists of two wireless sensor units utilizing two line lasers. The use of line lasers simplifies the setup process minimizing setup time. To make it even easier, the sensors comes pre-mounted on its fixtures and pre-set to the most common setup.

The Augmented Mechanic’s Solution RT-300 – A New Smart Reliability Tool from ACOEM
The augmented mechanic’s solution – RT-300 – is a smart reliability tool that combines on-the-spot machine diagnostics with tools for pre-alignment and precision shaft alignment, minimizing the time from fault diagnostics to corrective actions.

Soft Foot–What It Is and How to Minimize It
Soft foot is a common issue when aligning rotating equipment. It is a major cause of repeatability problems in shaft alignment measurements. In addition to alignment quality and repeatability problems, it can be a cause of machinery vibration, reduce life in electric motors, and cause internal clearance problems in gearboxes and pumps.

Is It Mils, or Thousandths, or What?
When we say, “Your laser displays in mils”, we’re asked, “What’s a mil?”

Roughing In Before Precision Shaft Alignment
Some people believe that precision laser shaft alignment has evolved to the point where pre-alignment steps, such as roughing in the alignment with a straightedge, are no longer needed. Well, quite frankly, those people are wrong!
The reason for roughing in the alignment has little to do with how accurately the lasers/sensors measure. It has nothing to do with how big the laser detector is, o -
