ABSTRACT
Desired real gears feature tooth ank geometry that is determined to provide the gears with the capability to be insensitive to any and all displacements of reasonable values of the tooth anks from their nominal disposition. With tooth ank geometries of this kind, displacements are simply absorbed due to the specic shape of the tooth ank. This makes it possible to reduce accuracy requirements to the gear, make accuracy tolerances wider and, thus, use less accurate and cheaper gears instead of more precise and costly gears.
