How To Double The Life Of Your Rolling Element Bearings

Please choose 1 morning and 1 afternoon OR 1 full day workshop

Speaker: Mark Barnes - DesCase

According to a leading bearing manufacturer, as many as 63% of rolling element bearing failure are caused by a lubrication issue, including incorrect lubricant specifications, under or over lubrication or contaminated lubricant.  In this session, we will look at how lubrication factors into ISO 28 bearing fatigue life calculations and present simple yet effective tools to extend bearing life well beyond what most companies are able to achieve.

You’ll learn:

• The lubrication factors that control rolling element bearing life
• Why specific film thickness is so important
• The role that additives play in bearing life
• How to avoid under or over lubrication
• Why as little as .05% water in oil can cut bearing life by two-thirds
• How particle contamination can reduce bearing fatigue life

Balancing Workshop - Multiplane Balancing Using Commonly Available Modern Tools

Please choose 1 morning and 1 afternoon OR 1 full day workshop

Multiplane Balancing Using Commonly Available Modern Tools

Pre-Conference Workshop

Authors:

Michael J. Titone, PE, Machinery Diagnostic Services Technical Leader, Bently Nevada

Steven P. Ciesla, PE, Machinery Diagnostic Services Technical Leader, Bently Nevada

Abstract

Balancing complex machine trains is often performed using expensive commercial software or proprietary software.  In both cases, the programs may not be readily available for some users.  Regardless of whether the user has access to software, an understanding of the calculation methodology is required to use the computer codes properly.  In the workshop, students will work along with the instructors to use Excel and Python to perform some of the calculations needed to develop a basic balancing program.  The instructors will assume that students have a working copy of Excel on their computer and that the students do not have a working version of Python.  The instructors will discuss the advantages and disadvantages of both tools.  The instructors will explain and demonstrate techniques to assist students with developing their own spreadsheets and programs.

De-mystifying Shaft/Coupling Misalignment Signature Using Vibration Analysis

Please choose 1 morning and 1 afternoon OR 1 full day workshop

Speakers: John Piotrowski, Turvac & Suri Ganeriwala, SpectrQuest

This hands-on interactive workshop is intended to clarify the shaft/coupling misalignment signature.  It will be presented in three parts:

• Part 1 is an overview of the current status of misalignment understanding and interpretation presented by world-wide recognized expert John Piotrowski of Turvac.
• Part 2 is a presentation of a comprehensive and systematic study of shaft/coupling misalignment signature using vibration analysis by Spectra Quest, Inc.  (Mate Toth and Surendra N (Suri) Ganeriwala).  Also, included in the study is the physics-based approach to misalignment.  This included a finite element model of parallel misalignment.  It will be presented by Dr. Suri Ganeriwala. 
• Part 3 is a hands-on demonstration of misalignment signature using a simulator.  Different couplings, speed issues, and loading will be examined.  Attendees are invited to bring their data collectors and participate.

Introduction To ESA/MCSA

Please choose 1 morning and 1 afternoon OR 1 full day workshop

Speaker: Howard Penrose, Ph.D., CMRP, President, MotorDoc® LLC

In this course we will discuss the relationship between ESA/MCSA and vibration analysis including system analysis versus point analysis.  The course includes electrical machinery theory and how ESA utilizes the magnetic field as a sensor.  We will explore the detection of electrical and mechanical conditions of the electric machine and driven equipment and power quality including how they inter-relate.  How to predict remaining life of a machine from ESA data and how to relate defects and degradation to energy and emissions.  The class will include case studies related to generators, AC/DC electric machines, transformers, and driven equipment.
