Precision of Spiral-Bevel Gears [PDF]
Journal of Mechanisms, Transmissions, and Automation in Design, 1983 An analytical method was derived for determining the kinematic errors in spiral-bevel gear trains caused by the generation of nonconjugate surfaces, by axial displacements of the gear assembly, and by eccentricity of the assembled gears. Such errors are induced during manufacturing and assembly.
