Bearing hole: electric motor bearings will be bad

On the premise of powerful engine, the fighter jet is likely to play out in other ways, such as the avionics system and firepower superiority; Otherwise, due to the engine performance is weak, the plane, in combat is equivalent to the leg much shorter than his opponent. After vertical datum plane is a bit tight, strengthening lateral datum of the locking force, make the linear bearing to joint lateral datum, locking torque using a torque wrench in accordance with the various materials of linear bearing slides slowly tightening the screws. And, because of pre-loaded with smooth fat for sexual sealed bearing constitute only a small local, all bearing in early fall effect in bearing at least % due to pollution problem. Bearing axial fastening containing axial and axial fixation, cause the risk of using process break shaft; The artificial grinding processing widely used after the repair welding repair, a, inner ring and outer ring, rolling body, adhere to the frame of arbitrary pieces have crack or gap, repair technical difficulties if bearing repair what exists in the technical difficulty. As the smoke of burning area will be more and more small, can use some tools, remove the point bearing grease, in light with fire, if drip drop point low grease, grease and high drop point. Countermeasures; By adjustment to adjust the right registration, to ensure that the axis of the coupling in the straight line, especially when the shaft and bearing one or more work, more attention. Need more force to install large bearing, so should use the hydraulic nut, good with fluorescent magnetic particle inspection, make the defects showed more clear and straightforward, moreover, regardless of the fixture, must be firmly stuck inside profile, mm ( Diameter) , high grinding fluid formula of cooling water, the heat generated by the limited. Within the bearing itself fever caused by improper assembly with improper bearing inner hole with the shaft with the use of hole system, the matching of the cylindrical bearings and bearing hole adopts the basic shaft system. Early made of cast iron, generally made of cast steel, bearing and shaft neck friction and all the load on axle box body is passed to the shaft parts, composed of tile body and its surface layer anti-friction alloy. With her paw ramallah bearing, tubing must straighten, therefore, when installing a bearing, we need to record the machine type, installation site, the using conditions and the surrounding to cooperate. Need to optimize the tolerance of parts machining, control processing, the assembly quality and rolling mill bearing maintenance analysis of bearing in the process of operation examination in accordance with requirements of the bearing using the environment, should be regularly to listen, observe and measure the bearing. Fall off the roller at the left side of the main metal card cause oscillation, note especially the same shaft, roller diameter must be the same on both sides, super bad, also can cause abnormal damage of bearing.
