摘      要：This paper proposes a novel method to predict the spur gear pair’s static transmission error based on the accuracy grade,in which manufacturing errors(MEs),assembly errors(AEs),tooth deflections(TDs)and profile modifications(PMs)are *** the prediction,a discrete gear model for generating the error tooth profile based on the ISO accuracy grade is ***,the gear model and a tooth deflection model for calculating the tooth compliance on gear meshing are coupled with the transmission error model to make the prediction by checking the interference status between gear and *** prediction method is validated by comparison with the experimental results from the literature,and a set of cases are simulated to study the effects of MEs,AEs,TDs and PMs on the static transmission *** addition,the time-varying backlash caused by both MEs and AEs,and the contact ratio under load conditions are also *** results show that the novel method can effectively predict the range of the static transmission error under different accuracy *** prediction results can provide references for the selection of gear design parameters and the optimization of transmission performance in the design stage of gear systems.
