Gibbons jargon buster #12: What are bevel gears?

Welcome to the latest in our series of blogs clearing up some of the terminology used in our industry. Today we’re asking what are bevel gears and why are they different to other transmission systems?

Bevel gears have conically-shaped faces and are used to change the direction of drive in a gear system by 90 degrees. Bevel gears can be seen at their most basic in hand drills and old-fashioned whisks, but they are also extremely useful for changing torque and speed between electric motors and machine parts.

Bevel gearboxes feature either straight or spiral-teeth gears. Straight teeth connect with one another a whole tooth at a time, making them suited to slower applications. Bevel gears with tapered, spiral-cut teeth (as seen in this image) connect gradually and therefore more smoothly, which is why they’re used for high-speed processes. This design also has the advantage of producing less vibration and noise than straight-cut teeth.

Here at Gibbons we install bevel gearboxes for many applications, including:

  • Manufacturing
  • Power plants
  • Conveyors
  • Mechanical gates and doors
