Bearing in the field of weapon equipment manufacturing applications

Magnetic suspension bearing technology can significantly improve some weapons and equipment performance, has important strategic significance, the demand of the military equipment field of magnetic levitation bearing technology includes the following areas: ship equipment requirements: detectability can be quiet low sex index to reflect. Improve the submarine quiet, will lead to reduce the vibration and noise on the submarine. Rotary parts of mechanical vibration is an important source of noise. Of magnetic suspension bearing elastic shaft system, the air gap between rotor and stator, through an air gap of the magnetic force, no direct contact with the operation process, avoiding the mechanical contact is difficult to avoid the impact of vibration, improve the quiet of submarines. America's early attempts to use magnetic levitation bearing state of reducing the noise of a submarine, Ohio and Virginia class submarines are used for magnetic suspension axle bearing, each submarine contains hundreds of magnetic suspension bearing, for its quiet submarine play a key role. For example is the magnetic bearing of the refrigeration system is only 73 db noise, 5 ~ 10 db lower than the conventional cooling system. Aviation engine: magnetic levitation bearing can meet the requirements of aircraft engine high-speed overload, and get rid of the reliance of the bearing to embellish wine system. Using magnetic levitation technology support turbine turns on, to further expand the limit speed of engine, is an important technology in the development of the future air engine. Aircraft engine working condition is very bad, high temperature, high speed and overloaded environment on the magnetic suspension bearing of the electrical and electronic devices strict requirements are put forward. This is when the magnetic suspension bearing used in aircraft engine needs to solve the main problem of magnetic levitation bearing in small engines, as well as in esteem than 15 ~ 20 large turbofan engine and intelligent engine with Mr Big application prospect. High density flywheel energy storage: in military equipment, the energy storage device is widely used. Flywheel battery for its high specific energy, larger than the work rate, small volume, fast charging, In minutes, while the chemical battery in hour meter) , long life, without any degree of exhaust gas pollution will point, is one of the most promising energy storage. Principle of flywheel energy storage flywheel rotating inertia is used to store energy, energy is directly proportional to the square of the speed, so the flywheel energy storage is the key to improve the flywheel speed. Magnetic suspension bearing with inorganic contact, can be in a vacuum environment to bearing, frictionless condition is an effective way to improve flywheel battery than energy, from the surface to the core of the flywheel energy storage technology. Magnetic suspension bearing flywheel accumulator is a carrier of electromagnetic catapult the ideal energy storage device, is now in the practical application for the new aircraft carrier in the United States. In some future in development of military equipment, such as accumulator electromagnetic gun, laser weapons, magnetic levitation bearing flywheel energy storage technology also plays a vital role
