N2 - The new internal S-gear and its contact characteristics were studied. Based on the S-shaped tooth profile cutter and relationship of machining motion, the teeth surface equations of the new internal S-gear were deduced, and the interference check of internal S-gear pair was derived. The modified tooth surface was constructed by superimposing the modified surface onto the standard tooth surface.On this basis, Matlab programming was used to calculate the coordinate of the three-dimensional grid node of the modified gear.The geometric contact characteristics and loaded contact characteristics of internal S-gear pair under different modifications and errors were studied by using tooth contact analysis (TCA) and loaded tooth contact analysis (LTCA). The calculation example was given, and the results show that the newly designed internal S-gear does not produce root cutting or interference, and the working teeth surface contact performance is good, and the correct meshing transmission can be achieved. After teeth surface modification, load distribution of internal S-gears teeth surface is improved effectively and its error sensitivity is reduced.
