Are Flexible Couplings Designed to be Misaligned?

| | | |

By on January 12, 2017

A common misbelief that occasionally comes up in our precision shaft alignment training classes is that, elastomer insert flexible couplings are designed to allow misalignment between rotating machinery shafts.  This is not the case.  Although this type of coupling may be more forgiving to the effects of misalignment, they are definitely not intended to be […]

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, […]

By on July 28, 2015

During the field portion of a recent training class vibration readings were taken before and after the precision shaft alignment of a pump and motor. This was done with a hand held vibration meter with a single plane accelerometer. The readings were approximately as follows: Motor NDE V-.07, H-.07, A-.11. Motor DE    V-.07 H-.07 Pump […]
