WebMay 22, 2024 · In the case of spur gears, a geometrically correct, non-interfering tooth profile generation is possible between the limit values of tooth profile shift coefficient (e.g., the limits are established by the undercut and the pointing) that causes tooth failures. WebA positive profile shift represents a theoretical cutter cutting deeper (leaving longer, thinner teeth), while a negative shift would cutter more shallow (leaving shorter, thicker teeth). Another way to think about it is positive profile shift numbers will allow for more backlash between two gears en-mesh.
