Abstract: Aimed at orthogonal variable transmission ratio face gear machined by the 3-axis CNC, a solution of coordinate based on CNC gear measuring center was proposed to detect the normal error of tooth surface. A gridding of tooth surface was made and the theoretical coordinates and normal vectors of the grid nodes were calculated. The comparison with the result of the transmission test and the theoretical data obtained the deviations. At the same time, the fundamental change regularities of bias was analyzed. Finally, the results show that the approach presented is proved to be feasible.

Key words: orthogonal fluctuating gear ratio face gear, gear measuring center, normal deviation of tooth surface, error inspection
