To address the limitations of existing gear tooth modification methods, a differentiated tooth modification method is proposed, where the modification amount of adjacent teeth varies according to a sine function. Initially, a mathematical model of the gear tooth profile varying according to a sine function is established. Then, using Adams software, a simulation analysis of the dynamic characteristics such as centroid angular acceleration, meshing force, and transmission error of gear pairs is conducted. The dynamic transmission performance of three sets of gear pairs—unmodified, normally modified, and differentially modified—is compared. Additionally, Simcenter 3D software is used to analyze the noise characteristics of these gear pairs. The results show that the differentially modified gear pairs, compared to the normally modified ones, have a maximum reduction of 2.47 % in sound power level at the fundamental meshing frequency amplitude. This proves that the differentiated modification method enhances the dynamic transmission performance of gears, offering a new method for gear vibration and noise reduction.
