本文提出机床变速箱噪声直接诊断方法。在箱体外壁听诊,可初步诊断某些主要噪声源的相关元件或所在方位。采用测头近距测试有关元件的噪声,能够迅速准确地确定变速箱的主噪声源。并使用精密声级计,测量箱体有关表面各点声压及对主要噪声元件近距频谱分析。
In this paper, a direct diagnostic method of machine gearbox noise is proposed. Auscultation in the outer wall of the box can be a preliminary diagnosis of some of the main components of the noise source or location. Proximity testing of the probe with the noise of the component allows the main noise source of the transmission to be quickly and accurately determined. And the use of precision sound level meter, measuring the surface pressure on the surface of the box and the main noise components close-range spectrum analysis.
