Selecting the correct coupling type for the alignment in your laser system

November 4, 2014

When performing shaft alignment, the most important goal is to align the machine to within proper tolerances. One criterion that has an impact on the tolerances that should be used is identifying and selecting the correct coupling type. In the setup shown below in Figure 1, spacer coupling tolerances were being used. However, in order to achieve a proper alignment, the alignment should have been performed using the short flex tolerances. Between the two shafts, a long coupling is used to connect them, however the connection between the motor shaft and the spacer (Left side in picture) is rigidly coupled and has no flexible element. Thus this setup should be treated as a continuous extension of the motor shaft. Therefore, the alignment should be performed using the short flex tolerances at the flexible coupling on the right side. Spacer tolerances should only be used when the distance between the two flex planes of a coupling is four inches or greater.

Let’s be S.M.A.R.T when establishing a Reliability Program

October 28, 2014

I have travelled to various industries throughout the United States and recently in Australia to educate reliability technicians, engineers and maintenance groups in the area of reliability. I have found that almost all are experiencing the same challenges with regards to sustaining programs. The only thing that’s different is the accent. Although I have encountered a variety of issues during my travels, a few always seem to be at the top of the list:

  • Communication
  • Not our “first go round”
  • Opportunity to implement some of the lessons learned
  • Not taking the “first step”

It is said that the majority of all programs fail. If this is true, then what is/are the reason(s)? What’s the common denominator? Many times it comes down to creating a shared goal and communicating effectively with our groups. As simple as this may sound, many among the group are driven in different directions and not working as a unit to reach the common goal.

Without a specific, clearly communicated goal we are destined to become another bad statistic. Without a goal there’s no passion and without passion no drive for success.

The following guideline may be helpful to creating a better effective goal.

Let’s be S.M.A.R.T when establishing a reliability Program.

  • S – Specific (be specific). If it’s a reliability program, what does it need to be successful? Correct parameters, alarms, reporting etc.
  • M – Measurable. You must be able to see if you’re making progress toward the goal.
  • A – Action Steps. What can you do (first step) to launch your program in the right direction?
  • R – Realistic. Stretch yourself, don’t let limiting beliefs prevent you from setting a goal. But don’t be unrealistic. You can always stretch out a little farther later.
  • T – Time period. Set a specific time period. Your expectations toward achieving your goals cannot be open-ended.

The Basics of Spectral Resolution for Motor Vibration Analysis

October 14, 2014

PUMPS & SYSTEMS • September 2014

Revisiting the fundamentals of data examination, time and resolution can solve equipment issues before they happen.

Inexperienced vibration analysts encounter a common problem: They are often expected to learn too much, too fast. Instead of taking time to appropriately understand the basics, new analysts must often move directly to a busy schedule of collection and analysis without much apprenticeship. Training is almost always in a group setting, and instructors often move too quickly through the material. The facts are learned well enough for an analyst-level exam, but an in-depth understanding is often taken for granted.

Accurate vibration analysis requires complete clarity on foundational subjects. Real-world applications demand more of young analysts than what they can learn in group training. Facility operations depend on a whole picture of how their equipment moves and where energy is used—and lost.

Midlands Technical College partners with LUDECA to mentor students as well as faculty on the benefits of PdM, RCM, etc.

October 7, 2014

Ludeca opens up new opportunities for students by donating equipment to Midlands Technical College.


Our company that provides corrective solutions through laser alignment and vibration analysis, donated some equipment to Midlands Technical College, a college located in South Carolina. We donated laser shaft alignment systems, shaft alignment simulators, laser pulley alignment tools to the college. These tools can help detect and correct machinery problems which affect machinery health and reliability.

Read the rest of the news article “Ludeca donates equipment to Midland Technical College” at Plant Services.

Watch Midlands Technical College’ MVPs of Advanced Manufacturing video which includes great testimonials from their mechanical and electrical technicians and features our ROTALIGN ULTRA laser shaft alignment tool
