Generation of a Crowned Pinion Tooth Surface by a Surface of Revolution

A method of generating crowned pinion tooth surface using a surface of revolution is developed. The crowned pinion meshes with a regular involute gear and has a prescribed parabolic type of transmission errors when the gears operate in the aligned mode. When the gears are misaligned the transmission error remains parabolic with the maximum level still remaining very small (less than 0.34 arc sec for the numerical examples). Tooth contact analysis (TCA) is used to simulate the conditions of meshing, determine the transmission error, and determine the bearing contact. Parallel axis gearing is very sensitive to misalignment of the gear rotation axes. Misalignment can cause edge loading of the teeth and thus premature failure of the gear components. Crowning one or both of the gear pairs can be used. The surface can be modified in the longitudinal direction or in the profile direction, or a combination of longitudinal and profile modification can be used to modify the surface.
