INA plastic bearing noise detection method

INA bearings rolling appearance if there is crack, indentation, or rust, like rivet rivet will attack the periodic vibration and noise, the cycle can be fixed but mostly, the corresponding relationship between rotating speed into the inevitable scars will continue in the channel, and scars on the ball, and the noise with the device and smooth and there is a premise of transformation. Device for this kind of noise control method are: no percussion bearings, plastic bearings and shaft assembly after a load bearing seat when avoid INA bearings oblique; Inventory to avoid the bearing corrosion and transportation to avoid the impact of vibration; Using high viscosity of smooth and fat. Rolling bearing with dust and other foreign body, will attack the periodic vibration and so-called dust, the vibration and noise of intrusive, and with or without. Dust acoustic control measures are: to improve the bearing cleaning method, before the device will be bearing, shaft and hole and matching parts all stern qing shen clean; Clear smooth agent inside the foreign body; Improve the plastic bearing seal; Avoid using data not pure or foreign bodies are embedded plastic stick to. Lubricant aging scleroma, choose wrong, lack of lubricant or attack can cause INA bearing vibration and noise, and the noise is not necessarily the rules. About this situation, as long as chooses appropriate smooth agent, adjust its smooth dose, extends the using life of smooth agent and reasonable change cycle. First, check the INA bearing vibration in the working situation from peeling, indentation, rust, crack and wear will reflect in the bearing vibration measurement, such as bearing vibration is very sensitive to plastic bearing damage, therefore, by adopting special bearing vibration measuring device ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Due to the measured values of bearing or sensor installation position and different using conditions, requires measurements of each machine in advance after analysis and comparison to determine the judgment standard. Second, check the INA bearings because the voice of the situation when rolling bearing even with slight stripping damage, such as would an exception and irregular, and so on with the sound of the measuring device can distinguish, USES the sound device, the size and quality of plastic bearings rolling sound in operation to check, have the effect of prevention in advance. Third, we should check the temperature of the INA bearing rotates if using the oil hole can directly measure temperature of bearing outer ring, is more appropriate. In general, the temperature of the bearing, generally based on the plastic bearings on the surface of the outdoor temperature can be predicted. If the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions.
