齿轮噪声是工业噪声的主要来源之一,齿轮广泛用于各类机组内,直径可大到数米,小到以毫米计,虽然其工作状态与条件有很大的不同,但工作时所产生的噪声的特性却很相近,本文就齿轮噪声的频谱特性进行了实验测量与分析,并就齿轮噪声的产生和它的控制途径进行了讨论。 Gear noise is one of the main sources of industrial noise. Gears are widely used in various types of units. Diameters can be as large as several meters and as small as millimeters. Although their working conditions and conditions are very different, they are produced during work. The characteristics of noise are very similar. In this paper, the spectral characteristics of gear noise are experimentally measured and analyzed, and the generation of gear noise and its control approaches are discussed.
