Face Gear

Face gears are those type of gears which are used in transmit power in circular motion. The power is transmitted usually at angles, which can be right angle or concave or convex based upon your included drive angle. Face gears are not very common in all industrial applications but the the application areas for which these gears are highly demanded are aviation and aeronautics industries. They are in the shape of circular disc with a ring of teeth cut on one side. The gear teeth are tapered towards the tooth's center. The face gears typically mate with spur gears. They have become highly popular for their use in high power, high precision applications.

Advantages of Face Gears

Materials Used
Face gears are made from variety of materials including stainless steel, brass, plastic, aluminum, gray iron, carbon steel & nylon.

Applications of Face Gears
Face gears are applied to a transmission for helicopters. Used for transformation of torque and rotation between intersected axes, face gear drives are an alternative one for a spiral bevel gear drive. Face gears are demanded for aerospace drive system applications. Helicopters using transmission systems depending on face gears have a higher survivability and safety.
