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(jī)為樣機(jī),利用現(xiàn)代聲學(xué)測(cè)試分析手段對(duì)其工作時(shí)定齒盤(pán)內(nèi)、外圈齒與相應(yīng)動(dòng)齒作用產(chǎn)生的旋轉(zhuǎn)噪聲進(jìn)行了試驗(yàn)分離研究,從而得出了爪式粉碎機(jī)旋轉(zhuǎn)噪聲的主要成分源自外圈定齒與其相互作用的動(dòng)齒產(chǎn)生的噪聲,并以此為基礎(chǔ),對(duì)定齒盤(pán)的齒數(shù)、齒形以及內(nèi)、外圈齒的相對(duì)排列位置等結(jié)構(gòu)參數(shù)進(jìn)行了降噪改進(jìn)設(shè)計(jì),通過(guò)對(duì)比性試驗(yàn)與分析,獲得了旋轉(zhuǎn)噪聲與上述結(jié)構(gòu)參數(shù)間的關(guān)系,并取得了負(fù)載6 . 7db ( a )的良好降噪效果。
