本文第一部分(载於本刊第三期38页)已经指出:要齿轮不发噪音必须在构造上、施工上解决一连串问题,必须知道噪音生成过程的基本规律。 决定齿轮嗓音强度级的因素 齿轮工作时通常旋转不均匀,而有频率散漫无纪的(声频)振动,所以生成噪音。齿轮表面振荡也是噪音的音源。 齿轮振动的 The first part of this article, which is published in the third issue of the journal, has pointed out that a series of problems must be solved on the construction and construction without gear noise, and the basic law of noise generation process must be known. Determine the level of gear voice level factors Gear usually work uneven rotation, and the frequency of indiscriminate (audio) vibration, so generate noise. Gear surface oscillation is also a noise source. Gear vibrating
