Everything You Need To Know About Bevel Gears

December 16, 2021

Imagining a functional industry without the help of gears is nearly impossible in this day and age. For effective torque transfer, it is essential to have gears in excellent working condition. All the equipment in use, including gears, should be in top-notch conditions to avoid any downtime as any downtime means a loss in profit. This blog lists different types of gears and everything you need to know about bevel gears.


Types of gears


Various industries use a wide range of gears depending on the applications. Following are some of the most common types. 


  • Spur gear
  • Helical gear
  • Screw gear
  • Worm gear
  • Splined shafts
  • Rack and pinion gear
  • Bevel gear


Everything you need to know about bevel gears


One of the distinct features of this type of gear is that the tooth-bearing base is conical in shape. The axes of the two shafts intersect, making them effective in torque transfer. Bevel gears work best when they are mounted on shafts that are 90 degrees apart from each other. Pitch angle is one of the essential factors used to categorize this type of gear. 

If the pitch surface of the gear is less than 90 degrees, they are classified as external gears. This is because the teeth in them point outwards. As opposed to this, if the pitch surface is more than 90 degrees, they are classified as internal gears. The teeth in internal gears point inwards.


Types of bevel gears

  • Mitre gears: Mitre gears are unique because of the fact that both the gears in use have the same number of teeth. For mitre gears to work effectively, they need to have the same pitch angles. 
  • Internal bevel: As the name suggests, the teeth are cut on the pitch cone's inside in this type of gear. 
  • Straight bevel gear: Straight teeth that taper towards the apex are straight cut gears' distinctive feature. 
  • Hypoid bevel: This type of gear has a hyperbolic pitch surface.
