EFFECT OF SETTING ERRORS ON MANUFACTURED SURFACES OF SPIRAL BEVEL GEAR AND PINION

Settings for generation of spiral bevel gear and pinion are determined in such a manner that the conjugate action in the gear pair is improved during their meshing. Any error in these settings would result in a deviation from the desired surface. Therefore, it is important to identify the critical settings and exercise greater care in their settings. In the present work, simulation of the generation process is carried out and the surfaces obtained are represented with reference to an idealized surface namely the involute spiraloid, established from first principle. The deviations of the surface resulting from the changes in the setting are also presented conveniently as normal deviations. From these results, the critical setting values are identified and are reported in this paper.
