Taking the ffc ? 23a disk mill as a specimen model, the rotation noise generated from the interaction between fixed claws distributed on the outer and inner circle of the fixed claw plate and the corresponding moving claws has been separated in an experimental study by the modern analytic method of acoustic. thereby, a conclusion that the principal component of rotation noise in disk mill comes from the interaction between the fixed claws on the outer circle and the corresponding moving claws has been reached. in accordance with the above, modified noise reduction design for the structural parameters such as the number of claws on the fixed claw plate, shape of claws and the relative positions of the claws arranged on the outer circle and inner circle has been carried out
本文以ffc ? 23a型爪式粉碎機為樣機，利用現代聲學測試分析手段對其工作時定齒盤內、外圈齒與相應動齒作用產生的旋轉噪聲進行了試驗分離研究，從而得出了爪式粉碎機旋轉噪聲的主要成分源自外圈定齒與其相互作用的動齒產生的噪聲，並以此為基礎，對定齒盤的齒數、齒形以及內、外圈齒的相對排列位置等結構參數進行了降噪改進設計，通過對比性試驗與分析，獲得了旋轉噪聲與上述結構參數間的關系，並取得了負載6 . 7db （ a ）的良好降噪效果。
