The crankshaft bearing, bearing type 22320 and 6320 is the same

Sauvy carbon nanometer polymer repair technology reconstruction project of the steel centrifugal fan field application case, in the process of debugging the bearing chamber not filling lubricating oil bearing caused by sintering, and the bearing chamber caused by wear, wear size width - mm depth Mm, bearing type. In bearing before installation, if need to add grease in the bearing, oil must be cleaned, right amount, usually users should put the bearing into the heated to ° - in mineral oil ° immediately when loaded on the spindle. May appear all sorts of flaws, first of all, should examine the power supply situation: joint connection is strong; Whether the switch contact meticulous; Whether the wire fusing; Whether the lack of equal power. Within the peripheral and outer ring, ring week all have race, spindle rotation can't stop if because ac contactor or dc relay is damaged, and off for a long time, can't control. According to the theory of viscous fluid computational power, N = KN = always. Bearing temperature monitoring in explosion-proof motor running, the need to monitor the temperature of the sliding bearing, but should pay attention not to judge only by bearing temperature bearing running condition, more important is the change of bearing temperature, often should observe the change of the bearing temperature and record, if discover the bearing temperature rise, and compared to before the numerical value of similar conditions are abnormal, must be determined to stop its reason and ruled out. Scene image: roller press in different phases of operation, the wear of the roll face is different, use manufacturers want to combine the situation of wear on the surface of the roller, using the above no longer process was carried out on the roller surface protection line repair in time, it is very necessary. Forced vibration forced vibration for many reasons, but because of forced vibration caused by the vibration frequency is equal to or double is equal to the frequency of vibration body itself, so it's easy to find out the vibration source, and. mm，Ymax=- ,, emsp; Dali special bearing ranking business negotiation & amp; emsp; Place the yoke iron to host core end face. Large carrying capacity, small size, low noise, long service life, any mechanical parts has its inherent vibration mode, different mode of vibration of corresponding to different vibration frequency. Clearance adjustable bearing means can move the relative axial bearing raceway position to obtain the required clearance, belong to this class have cone bearing and angular contact ball bearing and thrust bearing. %, can obtain the comprehensive mechanics performance of the strong ability to resist failure, Ar has both advantages and disadvantages of bearing parts, in order to promote the beneficial and abolish the harmful, Ar content should be appropriate, times, in addition, through the data with correlation analysis method and analytic hierarchy process (ahp) to calculate the magnetic liquid lubricant film characteristics parameters of the weight of the oil film stiffness influence degree.
