(1) scars and sound control approach INA rolling bearings if the appearance of cracks, indentation, or rust will attack like a rivet as a periodic vibration and noise, which can be fixed cycle but mostly with the rotational speed of the inevitable correspondence between injuries on the channel will continue attack, scar on the ball when it is now hidden, and this means noise and smooth with the premise there is an inevitable transition.
Such noise control methods are: the device is not a knock bearing, the cylindrical roller bearing and shaft assembly before loading ramp to avoid bearing mounted in the bearing housing; avoid shock vibration to avoid bearing corrosion during transportation and inventory; use Viscosity smooth high fat.
(2) sound and dust control measures
Bearing a dust and other foreign matter, will produce the so-called non-periodic vibration and dust acoustic, vibration and noise of uncertain size, and with or without.
Dust sound control methods are: to improve the cleaning methods bearing, the former means of cylindrical roller bearings, shaft, housing bore and mating parts all severe Qing Shen and clean; eliminate foreign matter smoothing agents inside; improve INA Bearing seals; avoid the use of data impure or foreign body embedded plastic stick holder.
Noise (3) lubrication caused by the elements and Countermeasures
Lubricant selection errors, lack of lubricant or onset of aging induration, cylindrical roller bearings can lead to the occurrence of vibration and noise, and this noise is not necessarily the rule. On this situation, as long as the selection of a suitable smoothing agents, its smooth adjustment of dose, extended service life and smooth agent reasonably determine the change cycle.
Failure to INA Bearing vibration Bearing obvious example: peeling, indentation, corrosion, cracks, wear, etc. will be reflected in the bearing vibration detection, so by using a special rolling bearing vibration measurement device (frequency analyzer and vibration analyzer etc.) to measure the size of the vibration, the specific circumstances of abnormal vibration frequency distribution can be inferred by the measured values due to the conditions of use of cylindrical roller bearings or sensor installation location is different and therefore requires prior measurement of each machine after analyzing and comparing the value determined criteria.
Typically SUNTHAI bearing temperature rise slowly as the start of the operation, 1-2 hours after reaching steady state normal temperature of the bearing due to the machines heat capacity, heat capacity, speed and load vary. If the lubrication, improper installation, the cylinder roller bearings abrupt temperature rise, there will be abnormal high temperature, then it must stop and take the necessary precautions.
