Using Bearing Defect Factor for Gear Defect Detection

| | | | | |

By on October 12, 2017

Bearing defect factor is a culmination of two technologies used for shock detection.  DEF is designed as an indicator for bearing defect detection, but can also be valuable in the detection of gear defects. Why is DEF significant? In the following data set are displayed Overall Vibration Velocity, Overall Acceleration, and Defect Factor.  The Overall […]

One Resolution to Motor Resonance

| | |

By on September 28, 2017

A customer was experiencing high levels of vibration on one of the HVAC motors. The cause for these high vibration levels was determined to be resonance. Resonance of this motor was seen in the vibration spectral data and was confirmed onsite with a bump test. This motor was not VFD driven and therefore the machine […]

Vibration Sensor Mounting Tips

| | | |

By on September 13, 2017

A vibration sensor (or accelerometer) measures vibration-simple, right?  But how and where you mount the sensor is CRITICAL to getting good information.  Here are some good tips to keep in mind. 1. Mount the sensor as close to the bearing location as you can safely do it. These sensors can measure vibration anywhere on the […]

BEFORE and AFTER: The Effect on Vibration Levels

| | |

By on August 24, 2017

One of the most enjoyable parts of precision shaft alignment training for me as a trainer, is the field portion. This provides the opportunity to build confidence that what the students learn in the classroom, really works in the field! In a recent Fixturlaser GO Basic class, the decision was made to align two recently […]

I read an interesting article in the June/July 17 issue of Uptime Magazine. It was titled “The Reliability Impact Within the P-F Curve” by Randy Riddell. Randy is the Reliability Manager for the SCA Barton Mill in Alabama. I encourage you to read the full article (https://reliabilityweb.com/articles/entry/the-reliability-impact-within-the-p-f-curve). The article includes the following graphic that I […]

Pump Vibration – Even Cavitation Isn’t Always Cavitation!

| | | |

By on August 2, 2017

Most people who work on, or around pumps are familiar with the term “cavitation”.  It is often used as a catch all phrase for any flow-related vibration on pumps, and is often reported by vibration analysts when: Pump noise level is high, Pump vibration is erratic, with lots of “noise” in the spectrum. But there […]

Setting Up a Motor-Gearbox for Vibration Measurement

| | | | |

By on May 25, 2017

Gearboxes are common in industry.  They are used to increase or decrease speed from the driver, provide increased torque, and change direction of power transmission.   There are two main types of commonly-used gearboxes:   GEARBOX TYPE Parallel or Standard Gearbox-one where the input and output shafts are parallel. Bevel or Right Angle Gearbox-one where […]

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 […]

I Completed a Precision Shaft Alignment & the Vibration Level Increased!

| | |

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 […]
