The geometry of a gear pair depends on the center distance and the included angle between the two axes of rotation along with the axial positions of the toe and heel (face width). During operation, loads can cause the gear system components to deflect such that the relative position and orientation between the gear elements change. This paper illustrates how certain gear body displacements are used to specify a gear pair’s geometric parameters that can improve contact during mesh. An illustrative example involving cylindrical gear elements is presented to demonstrate the procedure.
