在齿轮的设计阶段有几个目标：除了足够的负载能力和齿轮箱的高效率外，还必须考虑声学行为。对于单级齿轮箱，已经进行了几个关于噪声行为的改善的研究项目。由于多级变速箱齿轮啮合之间的相互作用，单级变速箱的知识不能无限制地传递。在这份报告中，实验研究进行了两级测试齿轮箱。通过对中间轴刚度和两级齿轮齿数的分析，对试验结果进行了分析。噪声产生过程将由测量信号沿着机器声学噪声产生过程来研究。首先，通过使用角旋转测量系统检测到的旋转加速度来分析齿轮啮合的激励行为。随后，确定齿轮啮合之间的传递路径，以评估源和接收器之间的相互作用。根据结果，将提供一个指导方针，在设计阶段必须集中在哪个阶段。
There are several objectives in the design phase of gears: Besides a sufficient load capacity and a high efficiency of the gearbox, the acoustic behavior has to be taken into account. For a single-stage gearbox, several research projects have been carried out regarding the improvement of the noise behavior. Because of the mutual interactions between the gear meshes at a multi-stage gearbox, the knowledge at single-stage gearboxes cannot be transferred without restrictions. In this report, experimental investigations are carried out on a two-stage test gearbox. The experimental tests are analyzed by means of the stiffness of the intermediate shaft and the number of teeth of the two gear stages. The noise generation process will be investigated by the measured signals along the machine acoustic noise generation process. First, the excitation behavior of the gear mesh is analyzed by the detected rotational acceleration using angular rotation measurement systems. Subsequently, the transfer path between the gear meshes is determined to evaluate the mutual interactions between source and receiver. Based on the results, a guideline will be provided which stage has to be focused during the design phase.
