The technical content of aero-engine is well known, and any proposition about aero-engine may be a huge systematic project. Controlling aero-engine technology and management capability is a hard challenge for individuals, enterprises, countries and nationalities. For this reason, the civil aviation engine market was monopolized by a handful of giants such as GE, PW and ro RR.
In addition to our self-study, innovation breakthroughs, it is especially important for these giants to learn modestly. Learning, analyzing, and applying these giants ' practical experience and practical data validation, cumulative results, this is no innovation itself can not be replaced. OEM manufacturers often have a unique source of information technology, not easy to use the improvement of their own work. In addition, the communication between the industry is not smooth, technical language and other barriers also affect the product follow-up and management optimization.
In the case of bearings, this is an aero-engine connecting the static and dynamic parts, supporting the rotating body and load transmission essential components. Engine and bearing manufacturers as well as airlines, maintenance units and other use of managers for each specific type of bearings have established a detailed maintenance system. However, the Maintenance Management unit of the bearing design and manufacture of the source of technical information is not much, not conducive to the maintenance of deep understanding, innovation and optimization.
And from the actual work, the maintenance management organizations are basically belong to the idea of ex post maintenance, that is, with the help of MCD and other means to explore how to detect the damage of bearing, how to alleviate the engine bearing failure, how to reduce the subsequent maintenance costs. Insufficient attention has been paid to the management of preventive work beforehand, and there are few specific prevention programmes and measures. The inadequate and asymmetric information has actually affected the prevention of many maintenance management systems.
