To give you the proper understanding of spur gears, here are the advantages they offer and their common applications.


Various Advantages of Spur Gears


These gears are the most common type of gears used in various industries and numerous applications. Featuring a very simple yet effective design, they offer plenty of benefits. Some of these advantages include:


  • Spur gears are simple components, very easy to design and install in drive mechanisms.
  • They are very straightforward and they are ideal for limited spaces.
  • These gears are suitable for driving systems because they have more power transmission efficiency.
  • A spur gear is built with teeth made straight and parallel to the axis of the gear. Eliminating any issue of axial thrust allowing ball bearings to be installed.
  • Spur gears are more efficient compared to helical gears with the same size.
  • They are quite reliable and offer constant velocity.
  • Spur gears are also considered a member of positive transmission because they don’t have any slippage.


Common Applications for Spur Gears


Listed below are the most common applications for spur gears, commonly employed across many industries.


  • Spur gears are commonly used in gear pumps and gear motors.
  • They are widely used in steel sectors for rolling mills, power units and cement units.
  • Nautical industries, especially in marine engines.
  • Gate controlling mechanisms, commonly in port sectors.
