Analytical checking of gears - Metrology & Quality Control

  Gears are inspected by using two different methods which include :
  
  1) Analytical checking
  2) Functional checking
  
  1) Analytical checking:
  
  - This method of checking involves actual measurement of tooth elements with the help of measuring instruments.
  
  - This method is used to measure or check gear tooth thickness, pitch, tooth profile or pitch diameter and also indicates error obtained.
  
  2) Functional checking:
  
  - The purpose of functional checking is to determine noise level, vibrations, etc. This checking indicates behavior of gears but does give any value of errors.
  
  - Hence, functional checking needs to be followed by analytical checking to identify errors.
