1、XK714直驅(qū)式主傳動系統(tǒng)設(shè)計[摘要]高速加工和高精度加工是世界范圍內(nèi)制造技術(shù)的兩種傾向.電主軸是機床用來實現(xiàn)高速,高精度加工的核心部件,在很大程度上,影響機床發(fā)展的總體水平.本文首先介紹了電主軸的發(fā)展及國內(nèi)外數(shù)控機床高速發(fā)展,闡述了電主軸是現(xiàn)代高速加工中高速主軸單元的必然,理想的選擇,應(yīng)用電主軸能夠提供的好處有可以提高生產(chǎn)率,更好的表面光潔度和降低生產(chǎn)成本,還可實現(xiàn)高精度薄壁零件和加工淬硬.高速主軸是一個發(fā)展的趨勢.開發(fā)電主軸是機械加工行業(yè)的迫切要求,闡述了先進的電主軸關(guān)鍵技術(shù),其中包括高速精密主軸軸承,動態(tài)熱態(tài)特性。電主軸的研究與具體設(shè)計,包括設(shè)計主軸支承形式、主軸軸承的配置
