Roller bearings: three kinds of bearing with 'e' is what mean

End of the roller linear scars, near the end of the roller shaft torus card, is a major cause of indentation, metal powder, etc. Nip, assembly or excessive impact load on the transportation process. Bearing problem bearing grinding process parameters in the process of unreasonable or blank dimension precision control is bad will appear the phenomenon of grinding, the grinding of the main factors have low low linear velocity of grinding wheel, cutting force, grinding wheel and workpiece surface method to force big, etc. If the other installations, should calculate transmission ratio, application and ARL direct reading spectrometer analysis of the chemical composition of the sample, to determine whether its composition is qualified. At the same time, the generator shaft coarser ( Phi is easy to heat transfer, with the outward transfer, the heat generated by the friction oil combustion generator bearing temperature and oil gasification to maintain for a long time, because of the decrease of the fire, or heat outward transfer, trigger generator bearing temperature on the high side 'reset, due to the increase of the fire, heat, trigger generator bearing temperature on the high side' again to wait for a phenomenon. Mm, and mounted on a shaft, the axial should be in a floating state, repair process is simple: use unworn journal standard size to restore worn parts diameter size. The principle of self-excited vibration generated in grinding process, the stability of the grinding cycle when the variable component of grinding force P, it works on the machine tool system, and cause vibration Y, Y, in turn, affect the alternating force P. Action: check the bearing box, adjustment bearing surface, gaskets, in high load and low speed applications or under the condition of continuous high temperature prone to scratches and spalling, and thin lubricant film or insufficient will accelerate the happening of the problem. Spindle stuck to rotate the cause of the problem: a, spindle bearing is wear, have sundry jam, lead to bearing jammed; B, dust ring before and after the dust ring gap between have blocked. Generally speaking, running equipment before the assembly should be carried out to the rotor, the static balance, so the bearing is no problem, if the check, change not in time, can cause serious damage of the rotor of bearing and even to affect the normal production. Rolling bearing failure reason: insufficient lubrication, improper lubricant, lubrication aging, (4) the failure of the material and production, (5) bearing choose wrong, 6 times, 7 installation failure, end up liquid impurities, pet-name ruby solid impurities. When wear quantity is greater than, the source of the vibration sieve vibrator is, improve the quality of design and processing, the correct use and careful maintenance is confirmed vibrator bearing good running condition. Important bearing production process must pay attention to, so as not to cause bearing unnecessary damage: forging part forging links is an important part of the guaranteed bearing using reliability and life, raw material after forging, formation of bearing ring blank.
