機床主軸用帶空冷墊圈軸承

采用獨創(chuàng)的軸承空冷技術(shù),使用高壓空氣冷卻軸承內(nèi)圈墊圈,在低噪音的狀態(tài)下同時實現(xiàn)高剛性和超高速運轉(zhuǎn)。通過材料和熱處理的改良,內(nèi)部設(shè)計的變更,潤滑的改善等非傳統(tǒng)方法,著眼于降低主軸發(fā)熱,采用獨創(chuàng)的空冷技術(shù)的“空冷墊圈”。通過該墊圈,可以減小內(nèi)外圈的溫度差,相比傳統(tǒng)軸承,高速旋轉(zhuǎn)性能提高20%,并在油氣潤滑和定位預(yù)緊的情況下,dmn值達到210萬,實現(xiàn)了世界最高水平的高速運轉(zhuǎn)性能。
