Abstract: A study of the effect of grinding wheel spindle eccentricity errors and perpendicularity errors on tooth surface errors is presented, aimed to find the quantitative relationship between them. Based on the meshing theory, the theoretical tooth surface and real tooth surface of gear are obtained. And the normal errors of tooth surface are obtained by analyzing the difference surface of the real tooth surface and the theoretical surface. The concept of sensitive orientation of grinding wheel errors and computing method for sensitive orientation of grinding wheel errors are proposed, and the relation between grinding wheel spindle errors and tooth surface errors is researched too. These works are helpful to tracing and compensation of the spiral bevel gears errors.
Key words: Eccentricity errors Perpendicularity errors Sensitive orientation of grinding wheel errors Grinding wheel spindle
