INA cylindrical roller bearing fault solution during operation

( 1) Scars of sound and its control method of 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 restraint measures are: no knock bearing, cylindrical roller bearing and shaft assembly after a load bearing seat when avoid bearing oblique; Inventory to avoid the bearing corrosion and transportation to avoid the impact of vibration; Using high viscosity of smooth and fat. ( 2) Dust acoustic INA bearings with dust and other foreign body and its restraint, will attack the periodic vibration and so-called dust noise, 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 cylindrical roller bearing, shaft and hole and matching parts all stern qing shen clean; Clear smooth agent inside the foreign body; Improve the INA bearing seal; Avoid using data not pure or foreign bodies are embedded plastic stick to. ( 3) Lubricating elements make up the noise and its countermeasures of lubricant selection error, lack of lubricant or aging scleroma, can cause a vibration and noise of the cylindrical roller bearing, 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. The vibration of the bearing of INA bearing failure effect is obvious. Such as peeling, indentation, rust, crack and wear will be reflected in the bearing vibration testing, so through the use of special rolling bearing vibration measuring device ( Frequency analyzer and vibration meter, etc. ) Can measure the size of the vibration, through frequency distribution can be deduced, under the condition of abnormal vibration measured values due to the use of cylindrical roller bearing conditions or sensor installation position and different, so need prior to each machine after the analysis and comparison the measured value of decision criteria to determine. Usually as operation began to slowly rise, INA bearing temperature reached steady state after 1 to 2 hours. The normal temperature of bearing for machine and different heat capacity, heat dissipating capacity, rotational speed and load. If the lubrication, installation is not appropriate, the cylindrical roller bearing temperature will go up sharply, there will be unusually high temperature, then must stop and take the necessary precautions.
