由于在各种机器中广泛应用的链传动工作速度的提高,降低其噪音的问题开始有了重要的现实意义。 为了揭示降低链传动噪音的可能途径,利用特制的噪音测量室进行了试验研究。按文献[2]的精确计划进行试验并按文献[3]的方法整理试验结果,可获得误差为±1分贝的鉴定数据。 The problem of reducing its noise began to have important practical implications due to the increased speed of chain drives, which are widely used in various machines. In order to reveal the possible ways to reduce the chain drive noise, a special noise measurement chamber was used for the experimental study. According to the exact plan of literature [2], the test results are compiled according to the method of [3], and the identification data with the error of ± 1 dB can be obtained.
