洛軸，全名洛陽LYC軸承有限公司，前身是國家“一五”期間重點建設項目之一的“洛陽軸承廠”，目前是中國軸承行業(yè)規(guī)模最大的綜合性軸承制造企業(yè)之一。在技術層面上，洛軸擁有國家級技術中心，曾研發(fā)出航空發(fā)動機軸承、軌道交通車輛軸承、重大裝備專用軸承等核心技術。并且，洛軸擁有國內軸承產品尺寸最廣、用途覆蓋面最寬、品種最齊全的生產基地，保持了多項中國軸承行業(yè)記錄。
The success application of earth pressure balance shield machine is organized by fe SuiDaoJu to adapt to hefei formation specially manufacturing equipment, not only to restore the original machine performance, optimize the system, and research and development for the first time to use the domestic
作為一家擁有六十多年歷史的企業(yè)，洛軸的產品被廣泛應用于各個領域，包括國防軍工、航空航天、風力發(fā)電、軌道交通、汽車摩托車、礦山冶金、工程機械、機床電機等行業(yè)。特別值得一提的是，洛軸還曾為我國的“神舟”飛船和“嫦娥”飛船系列提供過配套軸承，為我國的航天事業(yè)做出了貢獻。
technologies such as aero-engine bearing, rail transit vehicle bearing, major equipment special bearing and other core technologies. In addition, luoyang has the widest range of domestic bearing products, the widest range and the most complete production base, and has maintained many records of China bearing industry.
近期，在安徽合肥軌道交通三號線建設中，我國首臺使用國產主軸承的再制造盾構機圓滿完成2369.65米掘進任務。而其中的國產主軸承正是由洛軸研制而成，洛軸的主軸承經受住了實踐檢驗，對推動盾構機的核心部件國產化具有重大意義。
practice, which is of great significance to the localization of the core components of the shield machine.
此次應用成功的土壓平衡盾構機是由中鐵隧道局為適應合肥地層專門組織的再制造設備，不僅恢復原機性能，優(yōu)化系統(tǒng)，而且首次研發(fā)使用了國產主軸承。新制主軸承由中鐵隧道局牽頭，洛軸研制，主軸承直徑2.6米，能滿足直徑6—7米盾構機連續(xù)工作1.5萬小時以上。
main bearing. The new main bearing is led by the China railway tunnel, and the main bearing is 2.6 meters in diameter, which can meet the continuous work of the 6-7 m shield machine for more than 15,000 hours.
該項目的負責人表示，盾構機作為一種短使用周期、高價值成本設備，當前國內保有量已超過1500，大量盾構機面臨性能下降嚴重、使用成本不斷增加甚至報廢的問題。這次探索研發(fā)設備核心部件的國產化，不僅加快了核心技術的發(fā)展，而且以再制造推動制造的發(fā)展。洛軸，作為中國軸承行業(yè)規(guī)模最大的綜合性軸承制造企業(yè)之一，在此次主軸承研發(fā)中起到了良好的帶頭作用，助力國家掌握盾構機的核心技術，打破了少數國外公司的技術壟斷。
The project head, said of shield machine, as a kind of short life cycle cost of equipment, high value, the current domestic ownership has more than 1500, a lot of shield machine face severe performance degradation, increasing the cost and even scrapped. The localization of the core components of research and development equipment has not only accelerated the development of core
