詳細(xì)內(nèi)容:B40-166變速箱B50-57軸承 舍弗勒投資(中國(guó))有限公司, 施韋因富特 FAG航空航天再次領(lǐng)跑航空發(fā)動(dòng)機(jī)軸承研發(fā) 突破速度極限:舍弗勒開(kāi)發(fā)出新型航空發(fā)動(dòng)機(jī)軸承 將現(xiàn)有軸承速度指數(shù)從240萬(wàn)毫米/分鐘提高到400萬(wàn)毫米/分鐘 可滿足未來(lái)20年先進(jìn)航空發(fā)動(dòng)機(jī)的能效要求 每年可為全球客機(jī)節(jié)省燃油20萬(wàn)噸 舍弗勒集團(tuán)成員公司之一FAG航空航天有限兩合公司開(kāi)發(fā)出一款新型飛機(jī)發(fā)動(dòng)機(jī)球軸承,重新定義了航空高速主軸軸承的性能極限。作為德國(guó)聯(lián)邦經(jīng)濟(jì)事務(wù)和能源部航空研究項(xiàng)目下實(shí)施的合作項(xiàng)目“高效燃油系統(tǒng)”的一部分,F(xiàn)AG航空航天公司設(shè)計(jì)的這款發(fā)動(dòng)機(jī)軸承首次超越400萬(wàn)毫米每分鐘的速度指數(shù),且僅耗用最低限度的冷卻油量。在更高效的發(fā)動(dòng)機(jī)發(fā)展過(guò)程中,該新型軸承象征著一次重大意義的技術(shù)飛躍,每年世界各地的客機(jī)可降低共達(dá)200,000噸的燃油消耗量。 這一球軸承已通過(guò)舍弗勒試驗(yàn)臺(tái)驗(yàn)證,其中試驗(yàn)方案的要求(模擬飛行周期)在項(xiàng)目伙伴方德國(guó)MTU航空發(fā)動(dòng)機(jī)公司的密切合作下進(jìn)行了協(xié)調(diào)。 在相同油量下,新的冷卻設(shè)計(jì)對(duì)傳統(tǒng)軸承套圈的最大允許溫度成進(jìn)行特定調(diào)整,這意味著以完全相同的軸承溫度和油量實(shí)現(xiàn)了近70%的更高速度指數(shù),因此盡管圓周速度更高,但仍可使用當(dāng)前的材料和冷卻油。反過(guò)來(lái),若速度指數(shù)保持不變且使用更少量的冷卻油,則軸承溫度將降低達(dá)25攝氏度,且功率損耗減少達(dá)25%。所有的這一切都提高了軸承的效率及可靠性。 該型飛機(jī)發(fā)動(dòng)機(jī)軸承同時(shí)具有集成設(shè)計(jì)的油膜減震特征。此外,性能增強(qiáng)的“二次淬硬”滾道具有更強(qiáng)的魯棒性、強(qiáng)度及耐磨性,與此同時(shí)也降低了滾動(dòng)接觸載荷。新型球軸承更高的效率及可靠性也歸因于外環(huán)的直接冷卻和幫助減少摩擦及重量的陶瓷球。在航空航天領(lǐng)域應(yīng)用的軸承,即使在最嚴(yán)苛的工作條件下仍需具有最大可靠性。目前,在起飛初始階段,試驗(yàn)中發(fā)動(dòng)機(jī)軸承的速度指數(shù)可達(dá)240萬(wàn)毫米每分鐘。然而,要滿足未來(lái)航空公司的需求以及環(huán)境與氣候保護(hù)立法中的約束條件,在未來(lái)20年,有關(guān)飛機(jī)發(fā)動(dòng)機(jī)的機(jī)械效率和熱效率仍需取得進(jìn)一步的提高。因此,軸承的速度與熱負(fù)荷能力需要增強(qiáng),而要達(dá)到此目的,則要求具備新型材料、冷卻概念、生產(chǎn)制造與熱處理工藝,以及先進(jìn)的計(jì)算與模擬方法。 進(jìn)口軸承 原裝軸承 特殊軸承 英制軸承 聯(lián)絡(luò)15275821636 郵箱 Schaeffler (China) investment co., LTD., schweinfurt FAG aerospace leading aircraft engine bearing r&d again Break through the speed limit: schaeffler developed a new type of aircraft engine bearings The existing bearing speed index increased from 2.4 million mm/min to 4 million mm/min Can meet the requirements of advanced aircraft engine efficiency over the next 20 years Can save the global aircraft fuel oil 200000 tons each year Schaeffler group member company is one of the FAG aerospace combined company limited to develop a new type of aircraft engine bearings, to redefine the limits the performance of aviation high-speed spindle bearings. As Germany's federal economic affairs and the department of aerospace research projects under the implementation of cooperation projects "efficient fuel system, as part of the" FAG aerospace design of this kind of engine bearing 4 million mm per minute for the first time index, and only use the minimum amount of cooling oil. During the development of more efficient engines, the new type of bearing is a symbol of a significant technological leap, passenger every year all over the world can reduce the fuel consumption of a total of 200000 tons. The ball bearing was validated via schaeffler test bench, including the scheme of test (simulated flight cycles) in the project partner Germany MTU aviation engine company under the close cooperation of the coordination. Under the same amount of oil, the new maximum allowable temperature of the cooling design of traditional bearing ring ChengJinHang specific adjustment, this means that in order to exactly the same temperature and oil bearing realized nearly 70% higher speed index, so although circumferential velocity is higher, but can still use the current material and cooling oil. If the speed index stayed the same and, in turn, use a small amount of cooling oil, the bearing temperature will be reduced to 25 degrees Celsius, and to reduce loss of power of 25%. All this can improve the efficiency and reliability of the bearing. The aircraft engine bearing with integrated design of oil film damping characteristics at the same time. In addition, the "secondary hardening of performance enhancement" race has stronger robustness, strength and wear resistance, at the same time also reduces the rolling contact load. New type of ball bearing also attributed to higher efficiency and reliability of direct cooling loop, and help to reduce the friction and weight of the ceramic ball. Application in the field of aerospace bearings, even in the most demanding operating conditions still need to have the maximum reliability. At present, the take-off in the initial stage, test the speed of the engine bearing index is up to 2.4 million mm per minute. However, to meet the needs of future airlines as well as the constraint condition in environmental and climate protection legislation, in the next 20 years, the aircraft engine mechanical efficiency and thermal efficiency still needs further improvement. Therefore, the speed of the bearing and the need to enhance its capability of heat load, and to achieve this purpose, insist on new materials, cooling concept, manufacturing and heat treatment process, and advanced calculation and simulation method.
