Face Up To Save

A face gear transmission has an axis angle that can be chosen freely from 0˚ to 135˚, although they are typically configured at 90˚. The cylindrical pinion can move freely in the axial direction over the face gear teeth without affecting the contact pattern or backlash. This simple design facilitates a wide variety of geometries and the facility to take multiple drives off the face wheel, as well as providing high gear ratios in a single stage, which enables an infinite number of capabilities and configurations.
