B.I.T.S.

Bits of Information Task-Specific (BITS) micro-learning videos are designed for operators, maintenance personnel, and all who perform reliability tasks. Each BIT provides performance support for specific tasks. This focus on specific skills ensures that jobs get done right the first time. Every BIT is just one-to-two minutes long but provides the needed instruction, on-demand. TheseContinue reading “B.I.T.S.”

Coupling Gap

When performing a precision alignment, one step that is often overlooked is setting the coupling gap. If the coupling gap is set incorrectly it can put thrust into bearings that are not designed to take it, thereby reducing their lives. On larger sleeve bearing motors, incorrect coupling gap will cause the motor to run offContinue reading “Coupling Gap”

Implementation is About Momentum

Implementing Reliability Initiatives is a lot about momentum. Momentum is hard gained and easily lost. What happens when carefully scheduled training, and the implementation plans that it was supporting get disrupted as in the current global pandemic? Digital training is a useful tool to keep the momentum rolling until the live training schedule can resume.Continue reading “Implementation is About Momentum”

Are you introducing unbalance into your equipment?

Did you know that the key in your equipment should be sized properly to replace the mass that was removed from the shaft?  Also, don’t forget to make sure the keys are rotated 180 degrees from each other. Check out this weeks video for the key length formula. https://kvgo.com/Example/key-length

Understanding Rise/Run

This week we are going to take a dive into alignment.  Precision alignment is nothing more than eliminating slope which can be expressed as rise over run.  When you do an alignment there are triangles both vertically and horizontally.  The goal is to take the triangle out of the alignment and turn them into straight lines.  Alignment is thatContinue reading “Understanding Rise/Run”

Thermal Growth Fact or Fiction?

How hot is hot enough to consider how thermal growth may affect machine alignment? That is a trick question, because there is more to consider than just delta t. What is the casing material and what is that coefficient of expansion? Also what is the height of the shaft? When you consider these three questionsContinue reading “Thermal Growth Fact or Fiction?”

Soft Foot (Short Leg)

Since we consolidated shims on last week’s blog post, this week we will be focusing on how to check for Short Leg a.k.a Soft Foot.  Some of the effects of soft foot could include: bearing failure due to loss of clearance, gear mesh alignment in a gearbox due to loss of clearance, premature motor failure dueContinue reading “Soft Foot (Short Leg)”

Consolidating Shims

Following up on last week’s blog post about inspecting motor bases, this week we take a look at shims.  Just like machine bases, shims are also a key part in the foundation of the reliability of an asset.  While walking around the facility have you noticed more than 4 shims on a piece of equipment?  Did you knowContinue reading “Consolidating Shims”

Inspecting Machine Bases

This week on the Reliability Tribe blog we are going to begin discussing some simple inspections that can be done on a machine base.  All Reliability programs need to be built on a solid foundation (which we will discuss later).  Just like a Reliability program your machines need to also be built on a solid foundation.  Machine basesContinue reading “Inspecting Machine Bases”

Do Your Belts Slip and What is the Cost?

In keeping with last week’s theme on the use of strobe lights, this week we have an example of how you can use a strobe light to identify belt slip.  Did you know a 15% belt slip on a 100hp piece of machinery is not only reducing the motor 15 horsepower it could also potentially costContinue reading “Do Your Belts Slip and What is the Cost?”
