IKO bearing work wear failure reasons

The size and quality of IKO bearings rolling sound in operation to check. Because bearing even slightly stripping damage, such as would an exception and irregular, and therefore with the sound of the measuring device to identify, have the effect of prevention in advance. IKO bearing vibration is very sensitive to bearing damage. Such as peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measurement, therefore, through the use of special IKO bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values due to the use of sliding bearing conditions or sensor installation position and different, so need prior to each machine is analyzed by the measured value of the determined after judgment standard. IKO bearing temperature, generally can be deduced according to the bearing on the surface of the outdoor temperature, if the use of oil hole can directly measure temperature of bearing outer ring, is more appropriate. Usually, IKO bearing temperature with operation began to slowly rise, 1 - After 2 hours to reach steady state. IKO bearing normal temperature due to the heat capacity of the machine, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, the sliding bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. Based on a lot of test data, the average of the temperature of bearing outer ring while working in mechanical, for your reference. Due to temperature lubrication, rotational speed, load, the influence of environment, the temperature range of values in the table only said roughly. Using thermal device can monitor the bearing temperature at any time, and realize e. automatic alarm when the temperature is more than the household or stop to prevent the shaft accidents. About bearing damage status such as sliding bearing ring, guard card injury, as a reason to consider, lack of lubricant, not suitable for, for the defect of oil discharge structure, the invasion of the foreign body, bearing installation error, the deflection of the shaft is too large, also can have these reasons. The adjustment of the bearing stiffness and the alignment hole and bearing seat must have enough stiffness, and on the same axis sliding bearing hole must maintain strict misalignment. In addition, may adopt reactivity of diameter, the trigger roller sports wedge and overload. By positioning device positioning, IKO bearing the installation, should check whether the snap ring is good, whether can shoulder smooth level off, the surface of the presence of impurities dirt, etc. Through the test run to find is, in the process of the bolt bearing cap and tighten, constantly rotating angular contact ball bearing makes it find itself should is in the rotation, tighten the bolt torque by the regulation. In the process of screw shaft bearing cover again, constantly rotating shaft, bearing should be looking for is on its own. If the bearing rotating lightweight flexible, no binding, that is, has been looking for is, can be in accordance with the provisions, torque in 2 ~ 3 times evenly tighten bearing cover bolts. Intermediate support bearing so should adjust the drive shaft. So just to look at IKO bearing damage, damage is hard to come by. The real reason. But, if you know the used machinery, working conditions of the bearing, sliding bearing the surrounding structure, to understand before and after the accident, combined with several damage status and causes of bearing, can prevent the similar accident happen again.
