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.
