Bevel Gear

What is Bevel  oid gear ?

Bevel gears are used to connect shafts whose axes lie at an angle to each other, although in most applications the shafts are at right angles. The tooth profile is basically the same as used for spur gears except that the tooth gets progressively smaller as it approaches the apex of the projected cone.

Where to use ?

You’ll find bevel gears in a number of everyday items, devices, and machines, including automobiles, printing presses, power plants, cooling towers, marine applications, steel plants, and railway track inspection machines.

They’re commonly used in differential drives, which are capable of transmitting power to two axles that spin at different speeds (and are perfect for automobiles). They’re also used as the main driving action in hand drills, since the handle of the drill spins in a vertical direction to translate force to a horizontal rotation. You’ll also find spiral bevel gears as important components in rotorcraft drive systems, which need to operate at high loads and high speeds.
