Face gears are the gear wheel with cogs mortised into its face, usually
in conjugation with a lantern pinion. Face gear enables the transmission
of drive through an angle. Their use in high power, high precision
applications have become popular. Types of Face Gears
Face gears are of three types: standard face gear, helical face gear, and offset face gear.
Advantages of Face Gears
Face gears have many advantages. Face gears have high strength teeth and good contact geometry, which give high torque capability. Face gears help to ensure accuracy and rigidity.
Applications
They are used in aerospace drive system. They are used to transfer power between intersecting shafts as found in helicopter rotor transmission. They are also effective with insufficient lubrication, thus increasing the reliability of the aircraft. They also work with bad alignment between pinion and the rotor gear. Helicopters using transmission systems based on face gear have a higher safety and survivability. Face gears are supplied in wholesale to the aerospace industries
