Abstract: To reduce the deformation errors of cylindrical gear setting and promote the form grinding accuracy in the process of form grinding,the mathematical model with gear setting coupling errors was established based on form grinding principle of involute cylindrical gears.According to the gear measurement standard,a method to calculate the tooth surface deviations was proposed.The relationship of ground tooth surface deviations with respect to the gear eccentric error,the inclination error and the resultant error of two mentioned errors were investigated respectively.The sensitive errors were derived from the tooth flanks deviations by analyzing the gear setting errors.The experimental results showed the validity of the research conclusion,and the influence rule of gear setting coupling errors could be used to error tracing and identification in form grinding method.
