Keywords: SOV CNC gear hobbing machine State space model Error propagation Abstract. In view of the situation that the transmission elements of YS3118 CNC gear hobbing machine are too many and complicated, leading to transmission errors which cannot guarantee the machining precision, Based on SOV theory, with CNC gear hobbing machine as example, the method of using state-space model to describe the transmission error flow delivery is proposed in this paper.First the coordinate system to describe transmission parts gear geometric characteristics is constructed , mathematical modeling of the revolute pair deviations caused by machining errors or assembly errors is fulfilled, the coordinate system transformation containing error parameters in gear drive combined with kinematics theory is described and the expressions of errors flow in transmission process using state-space model have been set up.ultimately through the calculation example, the effectiveness of this method is verified.
