摘　　要：本研究旨在解决齿轮箱在啮合过程中由负载齿轮产生的啸叫问题。为解决这个问题,利用牛顿运动定律,建立一个齿轮副啮合的一维振动模型。在不改变齿轮基本参数的前提下,分别对齿轮齿顶和齿根进行修形。通过对比多种不同齿廓修形量的方案,计算齿廓修形量对齿轮强度及性能参数的影响,并根据齿廓修形量、修形长度和齿形公差绘制齿轮齿形检测的“K”形图。通过齿轮箱台架试验评估所提出的解决方案的有效性,证明齿轮啮合噪声的显著降低,从根源上改善齿轮啸叫现象。研究结果表明,齿廓修形是降低齿轮箱中齿轮啮合噪声的有效方法。In order to solve the issue of whining noise generated by loaded gears during the meshing process in gearboxes,a one-dimensional vibration model of gear pair meshing was established utilizing Newton's law of motion.The tooth tip and root of the gear were modified without altering the gear′s basic parameters.A comparative analysis of various tooth profile modification schemes was conducted,and the effect of tooth profile modification on gear strength and performance parameters was calculated.The K-tooth diagram of gear tooth profile detection was drawn according to the amount and length of the tooth modification as well as the profile form deviation.The effectiveness of the proposed solution was evaluated through a gearbox bench test,which demonstrates a significant reduction of the gear meshing noise.This improvement in the gear whine phenomenon can be attributed to the modified gear tooth profile.Overall,the results of the study indicate that tooth profile modification is an effective approach to reducing gear meshing noise in gearbox applications.
