Oil tanker engine bearing tools: needle roller bearing

Because of the silicon nitride high hardness, scrolling experience is creasing the convex edge smooth, until the raceway restore smooth, it will reduce the chance of local stress and spalling, significantly extend the service life of bearing. Figure on the gasket face crack morphology ( On the left side of the inner surface) Desmond tutu chamfering place crack (shown in The head) Magnification morphology tutu shown in gasket (transverse crack The tail) Enlarge topography gasket inner crack morphology on the surface of the tutu chamfering place crack (shown in The head) Magnification morphology tutu shown in inner surface crack ( The tail) Magnification morphology material and its microstructure examination will be gasket after preparation of metallographic specimen, placed in the MG type vertical routine inspection under microscope. Personal or Suggestions: increase the intensity of bearing inspection, such as bearing off the plane after open ended in the rolling element bearing not rotating case, first check the surface scratch do set processing. Check NSK bearing lubricants, lubricants in the friction between the two fingers, if you have any pollutant, can feel it; Or in the back, coated with a thin layer of oil, and then seal the light. By bearing and end cover of generator stator and rotor connected together, can make the rotor spinning in the stator, do the exercise cutting lines, thus induced potential, through terminal lead, in the circuit, the electric current is produced. For the removal of tapered bore the bearing, don't put the end of the shaft before disassembly clamping nut or institutions down completely, only the pine to avoid bearing fall accident. Because in most cases the bearing inner ring with the axis of rotation, cooperate must have fixed interference between, but the amount of interference and should not be too big, in order to protect and disassemble because it is to prevent the inner ring stress is too large. Grease is a thickening agent which is composed of dispersed in the liquid lubricant is kind of stable solid or semisolid product, which can add to improve some characteristics of grease additives and fillers. Oil shock absorber is unable to repair, replace the solution is only a, due to the smaller body SMART, so on the shock absorber spring force is small, also change very easy. Of rolling bearing to adapt to the low speed of rotation, if you are using a high speed rotary rolling bearings need special requirements, can be used according to the load factors such as reasonable selection of the model. Also need a lot of objective conditions, for example, must have proper raw material and the metal smelting capacity, only in this way can the strength of the Russia's China and the United States and Europe. Here is to use several methods of fixed speed reducer in adjusting method of the bearing clearance, shaft end cover both ends fixed way this structure often USES fixed bearing outer ring, simple structure, easy to use.
