“…However, this method is not suitable for calculating the bending stress. Barbieri et al [15] explored the performance of the gear pair with tooth profile modification by performing Loaded Tooth Contact Analysis. Numerous researchers like Tesfahunegn [16] established models of modified gear pair in Pro/E while analysing it in other software, which may lead to data loss.…”

The spur gear mechanism with the standard involute profile may generate noise and shock because of tooth structure and transmission principle, resulting in substantial transmission errors. These limitations can be effectively resolved through tooth profile modification. To address the defects and deficiencies of existing tooth profile modification methods in terms of the modification principle and effect assessment, this study proposes an adaptive method of tooth profile modification with alterable tooth profile for spur gear mechanism. A corresponding simulation method for evaluating the modification performance of the gear transmission was introduced in detail. The final shape parameters of the modification profile were determined by orthogonal experiments. Simulation results show that tooth profile modification for involute spur gear does not affect bending and contact stresses. The process can also effectively improve the stability of transmission. The impact and noise of gear pair with tooth profile modification significantly decreased during meshing. The proposed method exhibits stronger adaptability compared with other existing methods of tooth profile modification. Moreover, the proposed method can adaptively determine the optimal modification parameters based on different conditions and obtain the ideal modification effect.

“…However, the method only studied two simple modification curves, linear and parabolic, and the influence of working condition parameters was not considered. Besides, the accurate model for gear pair with comprehensive modification was built by Barbieri et al [18], and they applied analysis using the accurate model, but they did not explored the method and theory of modification.…”

There are some issues that should be solved like load shock, vibration, and uneven load distribution during transmission of involute spur gears. However, common modification methods such as axial modification as well as profile modification could not solve these problems once for all. Hence, a novel method of comprehensive modification was proposed, and the evaluation methodology of transmission performance was drawn up too. Changing modification parameters can control transmission performance of gear unit, which can generate many different modification ways. Besides, based on the orthogonal experiment method and evaluation methodology, optimal modification ways can be chosen for gear pairs working in different conditions. Taking a set of spur gear pair as an example, an ideal modification way was obtained. In addition, analysis results verified that conducting comprehensive modification could enhance the meshing performance once for all.

“…For example, Barbieri et al [2] and [3] and Bonori et al [4] explored the effects of profile modification using tooth contact analysis (TCA); furthermore, they used a genetic algorithm to optimize the method. An original method to calculate the transmission efficiency was proposed by Baglioni et al [5], and the influence of tip relief was also discussed.…”
