What’s the Point of Precision Shaft Alignment When We Use Flexible Couplings?

| | | | |

By on July 21, 2016

This is a common misconception in some industries surrounding flexible couplings. Some maintenance and production individuals believe that flexible couplings are designed to allow for a few degrees of misalignment.  This is not quite the case.  While flexible couplings do tolerate some amount of misalignment, this is not their intended purpose.  The greater the misalignment, […]

Shaft Distortion and Electric Motors

| | | |

By on July 15, 2016

Although shaft distortion due to misalignment affects more than just the electric motor, here are a few things that are a telltale signs you may have an alignment issue. In a perfectly straight shaft, the centers of each shaft cross-section from end-to-end of the shaft lie on a straight line. A shaft is bent if […]

Announcing the 4th Annual “Realigning America Tour”, Free Shaft Alignment and Machine Maintenance Seminars

By on July 7, 2016

VibrAlign will take to the road for its 2016 Realigning America Tour, visiting 19 cities in 13 states. While the past tours have focused on sharing best practices for shaft alignment, couplings, and machinery diagnostics, the 2016 tour will also include case studies to highlight how best practices are actually implemented. The 2016 Realigning America […]

Environmental Impact on Precision Shaft Alignment

| | | | |

By on July 6, 2016

We work with clients in many types of harsh climates, from cold with rain, sleet, snow & ice to hot humid and hot & dry and everything in between. Whatever the climate, the need for equipment maintenance intensifies with the severity of the climate.  Harsh climate conditions will create situations where precision shaft alignment of […]

Low Cost Thermal Diagnoses of Misalignment and Machinery Health

| | |

By on June 29, 2016

With the availability and decreasing prices of technology to help diagnose rotating machinery health, machine failure should be a diminishing concern. Thermal imaging cameras can be expensive, however these cameras have very detailed diagnostic abilities and high resolution. Reduced cost Thermal Imaging has recently become available through various sources. I recently purchased an infrared camera […]

Coupling Tolerances vs. Shaft Alignment Tolerances, What’s The Difference?

| | | |

By on June 24, 2016

Plenty! This question still comes up fairly often in our training classes. If you look any of the coupling manufactures installation instructions there is a chart for the maximum allowable misalignment based on the coupling size. These tolerances are for the coupling, what about the machines the coupling connects? Shaft alignment tolerances are more about […]

MACHINERY VIBRATION PROBLEMS – PART 4 BEARINGS

| | | |

By on June 6, 2016

  In industrial machinery, the centerpiece of vibration analysis is the ability to detect bearing problems BEFORE the bearing fails.  Even more beneficial is detecting the root cause of a bearing problem before damage is done. The bearing really is the heart of the rotating machine.  There’s a plethora of bearing types and designs. There […]

MACHINERY VIBRATION PROBLEMS Part 3-Lubrication

| |

By on May 18, 2016

LUBRICATION Lubrication is sometimes incorrectly thought of as a job for unskilled workers, apprentices, or operators.  When I hear a maintenance person say, “I’m just an oiler”, I cringe a bit. Proper lubrication methods, formulations, quantities, and procedures are essential to machine reliability. A machine can no more do without lubrication than it can do […]

The Three T’s

By on May 6, 2016

I have been in industrial maintenance longer than I have not. A portion of that time was spent in Maintenance Management. One lesson I learned was, that in order for a team leader (or company as a whole) to be successful, the entire team needs to be successful. I tend to simplify things, maybe to […]

Bolt Holes – Size matters!

| | |

By on April 28, 2016

I was asked to help a customer align a 500HP Motor / Blower.  The new motor came in on a skid, was lifted into place with a crane, new electrical boxes fitted and coupling put into place.  Now the easy part, the precision shaft alignment! We took two sets of measurements which repeated.  Made one […]

X, Y, & Z Axis. Does the Z Axis Affect Shaft Alignment?

| |

By on April 14, 2016

Does the z axis affect alignment? In short, no it does not. There are aspects of the z axis that could affect the running of a machine, but rotational shaft alignment is not of them. What is the z axis? The X and Y axes are references to horizontal and vertical planes respectively.  With regard […]

By on April 6, 2016

As technical trainers, we travel all over the country visiting factories, mills, power plants and refineries.  Just to mention a few.  We see and work on equipment of every type and size. From small 10 HP electric motors and pumps moving cooling water, to house sized engines turning generators that power our cities. Out of […]

By on March 30, 2016

Laser Shaft Alignment tools are a great asset for today’s maintenance professional, enabling them to perform precision shaft alignments to very tight tolerances; and do so quickly when using the VibrAlign Verti-Zontal Process. Laser alignment systems are a tool and as such show the user what is occurring “mechanically” during the alignment process, including if […]

UNBALANCE

| | | |

By on March 24, 2016

Unbalance is another common machinery vibration problem.  Unbalance is the uneven distribution of mass around a rotating axis. Any rotating machine can have an unbalance problem, not just fans.  It is important to note that once rotating machinery components are balanced, they should stay balanced until something changes.  These changes are normally: Dirt, paint, or […]
