Profile shifted spur gear

WebPhysically, profile shift refers to the distance between a gear's theoretical pitch diameter and the cutting tool datum line. Without consideration for the manufacturing process, it is difficult to assign physical meaning to profile shift, in which case considering the gear tooth thickness directly is more intuitive. Tooth tip thickness ¶ 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.
