Spur Gear Systems

  • Spur gears are usually located on parallel shafts that rotate in opposite directions (for external gears) or in the same direction (for internal gears). 
  • The location of spur gears depends on the application and design of the machine. For example, spur gears can be used in gearbox, clock etc.
  • The function of spur gear is to transfer motion and power from one shaft to another in a mechanical setup
