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 […]

By on September 1, 2016

We recently received a customer request about shim safety.  An employee at the customer site had experienced a “near miss” safety issue due to walking too closely to a machine, and getting their clothes caught against a shim.  Since I have a scar on my right thumb caused by a 3 mil shim, I thought […]

Three Major Contributors to Equipment Failure

| | | |

By on August 24, 2016

Past maintenance & production issues found in the industrial or manufacturing environment are still prevalent even in today’s equipment reliability focus. The major contributors to equipment failure remain the same, misalignment, unbalance and assembly errors. Another is lubrication, Mr. Stan Riddle addressed this in one his blogs “Machinery Vibration Problems part 3 – Lubrication”. Let’s […]

Reduce Force to Maximize L10 Bearing Life

| | | |

By on August 17, 2016

Simply put, L10 bearing life is the number of service hours that 90% of bearings will survive or conversely 10% of bearings will have failed. L10 life: is the preferred term in specifying bearing life and is defined by The American Bearing Manufacturers Association (ABMA). A bearing life equation is: This calculation assumes proper installation […]

By on August 10, 2016

As my grandma used to say, “When you don’t know how to use your head, you’d better know how to use your legs”. Thanks to a feature on our FALCON data collector I didn’t have to call her to tell her how right she was (again)! Two of us were performing data collection on a […]

MACHINERY VIBRATION PROBLEMS AND SOLUTIONS, PART 5, MECHANICAL LOOSENESS

| | | |

By on August 3, 2016

Mechanical looseness is a very common machine vibration diagnosis.  It is often overused-becoming a “catch all” category for undiagnosed vibration.  It can be caused by a multitude of things that may seem to have no relationship to each other, such as:   Loose bolting                                               Coupling looseness or backlash Belts Too Loose                                           Cracked welds Improper bearing […]

Alignment and Vibration: What is the correlation?

| | | |

By on July 27, 2016

This is a subject that comes up relatively frequently with our customers and observations from the field.  The purpose of today’s blog post is to illustrate what can and often does happen.  While misalignment can and does present with easily identifiable vibration signals; often it does not.  Misalignment may be present in a machine, developing […]

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 […]

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 […]
