Your Essential Guide to Bevel Gears

Bevel gears are a unique type of gear because of how differently it works in comparison to other gears. A bevel gear has two shafts that intersect with their tooth-bearing faces meeting one another and creating an axes. They are a product that we produce at True Gear & Spline that we are proud of.


Whatever your gear or spline shaft requirements are, we can handle them. At True Gear & Spline, our business is founded on the expertise and experience we have with our manufacturing with technology. We offer the capability of handling any order that you need. Our gears and splines are quality assured and checked by our manufacturers.


What Are the Types of Bevel Gears?


Bevel gears have different applications across a variety of unique industries. You can find a bevel gear in food canning equipment, lathes and mills, and even fluid control valves. These gears are often mounted on shafts that are separated by a 90-degree angle, although a bevel gear can work at other angles.


Here are a few different types of bevel gears:


  • Straight Bevel Gears: This bevel gear has a pitch surface shaped like a cone. Additionally, it has straight teeth that are tapered toward the apex.
  • Spiral Bevel Gears: Spiral gears have curved teeth that allow for smooth and gradual contact. These gears should always be replaced in pairs, so it is essential when you purchase a spiral gear that you are getting the best quality on the market.
  • Zerol Bevel Gears: Similar to a spiral gear, zerol gears have curved teeth but their spiraling angle is zero. Zerol gears offer functionality like no other, they are known to be more accurate and quieter than other bevel gears.
  • Hypoid Bevel Gears: These gears are known for their hyperbolic pitch surface as opposed to a conical one. Typically found in the rear axles of cars, hypoid gears are great for their high efficiency and minimal sliding.
