Abstract: Aiming at the large difference between ISO 1328-1:2013 and its previous version in 1995, the definition and evaluation methods of profile deviations in ISO 1328-1:2013 were studied. The detailed calculation results were analyzed including the profile evaluation range and profile evaluation length, the mean profile fitting, tooth profile measurement data filtering method. In accordance with ISO 1328-1:2013, the tooth profile deviation evaluation process was given and tooth profile deviation evaluation software was developed. With the measurement data of tooth profile obtained by the gear measuring center, the tooth profile deviation was evaluated and the results of tooth profile deviation based on two versions of ISO 1328-1 were compared and analyzed. The evaluation parameters, evaluation results and evaluation curves of tooth profile deviation were calculated and displayed in the developed software. The results indicate that there are certain differences between the evaluation results based on the two versions of the same group of tooth profile measuring data. The differences are in accordance with the changes made by ISO 1328-1:2013 in the evaluation of tooth profile deviation compared with the previous version, which can provide reference for the application of ISO 1328-1:2013.
