What material is the characteristics of high temperature resistant bearing the engine?

There is no doubt that the aircraft engine is a battle plane, one of the most crucial component for determining a battle plane all the strength is strong, the special engine performance index is one of the key indicators of the skills. The engine of the necessary conditions, a battle plane is perhaps full play out in other areas such as the superiority of avionics system and fire; Otherwise, because the engine performance foundation weak, the plane in combat is equal to the legs are much shorter than competitors. In more complex structure of engine, engine bearings are the most crucial in this structure, the center of the structure. Can be said that, the engine of the entire structure, all of them are under the propulsion of bearing working; Therefore, bearing is depends on the engine performance index of a 'brain'. To make its processing technology are the most cultured; You can see from the exterior, bearing is just an ordinary 'big iron rod; Obviously, this' big iron rod has tremendous skills details; Structure such as compressive strength, load ability to work and driving system efficiency, etc. In the numerous performance indicators, heat resistance performance, is the first heavy engine. If an engine bearing cannot afford high-speed operation of the intense friction generated under high temperature, the strong ability to work load and lubrication degree, all of them are joker. In a Russian engine, Russia is fine casting type selection, and the chosen is welded. The sake of our country depends on the materials and structural mechanics, temporarily not to overcome the problem of heat resistance. In yield to make the whole process of the bearing, the complexity of the processing technology and the precision specifications are very high; Perhaps hardly countries usually do it. Therefore, at present all over the world can do autonomy from making battle planes a handful of countries. And bearing the fruit of the production, not only to have the necessary information to learn, strong structural mechanics and processing technology. Will also be necessary to many objective factors, such as, it is necessary to have the appropriate raw materials and excellent metallurgical professional working ability. In addition to this, the engine of the whole test process is not far, it is necessary money into a large number of financial resources, and its excellent talents and machinery and equipment in order to develop a variety of types of test, the funds to invest a lot of scientific research for a country, also can lead to very heavy economic burden. Only the Russia and Europe all the strength of this can be done. While other countries, only rely on from this a few big all power hand skills. Overall, want to have a powerful engine, need to have a lot of necessary conditions, strong materials, produce fine rigorous production processing technology and the prosperity of structural mechanics, indispensable.
