| Abstract:Modification plays an important role in improving gear meshing quality and reducing gear transmission vibration and noise. Based on KISSsoft software, the crankshaft gear of a medium-speed diesel engine was studied and the gear shape modification design analysis was carried out. The changes of parameters such as tooth surface contact stress, gear transmission error and root bending stress before and after crankshaft gear modification were obtained, which provided a theoretical basis for optimizing gear modification in the future. |
