摘要
以单级圆柱齿轮减速器为研究对象，综合考虑齿轮啮合过程中轮齿时变啮合刚度、误差及啮入冲击的影响，建立了传动系统动力学模型。以轴承动载荷为激励，采用FEM/BEM方法计算了减速器振动辐射噪声，得到齿轮箱声场场点的噪声谱，分析了啮入冲击对减速器振动噪声的影响；阐述了箱体辐射噪声的影响因素，对多工况下齿轮箱振动噪声辐射进行了计算，得到了噪声辐射随齿形误差及负载的变化规律，为减速器的减振降噪设计提供了理论依据。
Abstract
A dynamic model of the cylindrical gear transmission system is developed in consideration of the time-varying mesh stiffness, gear errors and meshing impact, in the process of meshing. Dynamic load of the bearing is taken as the excitation. Noise radiation of the gear reducer is calculated by using FEM/BEM, and then the noise spectrum of the gearbox is obtained. The meshing impact that influences the noise of the gearbox is analyzed and the factors that affect the noise of the gearbox are stated. The effect of gear error and operating load on vibration and noise radiation are studied, and the rule of noise radiation with gear error and operating load are obtained. The studies will provide useful theoretical guideline to the design of the gearbox.
