Balancing Rotating Machinery

The bottom line: you must achieve precision balance.

In this course, you will learn how to recognize unbalance and set up the balance job for a successful balance. The course starts with the basics – providing an introduction to vibration, phase and vectors, and fully explaining the balancing process. You will first learn how to perform a single plane balance with vectors. You will learn how to balance a machine using the single-plane and two-plane balance functions of an analyzer. 

Course Breakdown:

  • What unbalance is, why it occurs, and why it is important to precision balance a machine 

  • Understanding phase: what it is and how to measure it
  • Phase conventions, and representing phases with vectors

  • The relationship between the phase angle and the actual heavy spot on the rotor

Different types of unbalance:

  • Static unbalance
  • Couple unbalance
  • Dynamic unbalance 
  • How to diagnose unbalance with vibration analysis, phase and other techniques 
  • Preparing for the balance job: safety first
  • Single plane with vectors
  • Single plane with a balance program
  • Two planes with a balance program
  • The static/couple method
  • Balancing overhung rotors
  • Four-run-no-phase balancing
  • Selecting the size and location of trial weights, splitting and combining weights
  • Balance quality standards: ISO/ANSI/API/Navy
