降低減速機運行時的齒輪傳動噪聲已成為行業內的重要研究課題，國內外不少學者都把齒輪傳動中輪齒嚙合剛度的變化看成是齒輪動載、振動和噪聲的主要因素。用修形的方法，使其動載荷及速度波動減至朂小，以達到降低噪聲的目的。這種方法在實踐中證明是一種較有效的方法。經過多年研究，提出了通過優化齒輪參數，如變位系數、齒高系數、壓力角、中心距，使嚙入沖擊速度降至朂小，嚙出沖擊速度與嚙入沖擊速度的比值處于某一數值范圍，減小或避免嚙合節圓沖擊的齒輪設計方法，也可明顯降低齒輪噪聲。 ?？怂箍等鴺藴y量機 YB6040花鍵銑床 4米外圓磨床鏈輪數控淬火機床 T2235深孔鉆數控加工車間現場 4米數控落地鏜 Y51125插齒機 C5116立式車床 DHXK2618龍門式數控銑床
