Regular maintenance of TIMKEN roller bearing should have performance

Need to stress is that link TIMKEN bearing lubrication and cleaning is very important. So when we raid was carried out on the bearing, the draw clean bearing situation, and then remove the perimeter of the bearing parts. To pay more attention to the master, it is cowardly of oil seal parts, fruit and was raided and demolition demolition need cockiness special be careful, don't be too much work, so that form the damaged parts. Then carefully the raid of roller bearing oil seal and its surrounding parts, if not present adverse symptoms, be sure to switch off and bad seal will cause the damage of the TIMKEN bearings, the bearing cloud differences and the formation of a equipment downtime. Diameter of axle and bearing shell direct contact to prevent adhesion formation and boundary lubrication performance. Factors influencing the friction pair friction compatibility of materials is: ( 1) As a deputy to the difficulty of the composition of alloy materials metallurgy. ( 2) Materials and affinity of lubricant. ( 3) Become vice material in the absence of the friction factor of lubrication condition. ( 4) The microstructure of materials. ( 5) Thermal conductivity of materials. ( 6) The size of the material surface energy and the characteristics of the oxide film. We also have to raid roller bearing lubricant. Lubrication is very main, but not for bearing, nor for the bearing. Please note, however, bearing should not add too much grease. A raid on the bearing lubricant way is: with little lubricant is friction between two fingers, and if no pollutants have no, is a feeling; Or layer is coated on the back of a lubricant, and then to light a raid. And then there is a change in TIMKEN bearing lubricant. After using oil lubrication bearing is xie used engine oil, bearing remission coating technology introduction and should be. If can of words, novel should impregnated with oil and machinery are low speed reverse for a few minutes. As far as possible make the oil collecting residual pollutants, and then purging in addition to the oil. Note: the oil is using best course before the filter. And the use of grease lubrication of the bearing is a change in grease, by Joe in addition to the unit when avoid belt without any part of the cotton material come into contact with the bearing. Due to the residual fiber may wedging between rolling pieces and formation damage induced intended to remove the bearing fault elements, especially the use of small bearings need more attention to this problem. A, overheating. Roller of raceway, steel ball retainer or change color, show that bearing overheating. A rise in temperature will reduce lubricant effect, make the oil desert formation or disappear entirely. Temperature is too high, can make the raceway and the material of steel ball annealing, hardness decrease. This is mainly the cooling adverse or overloading, under the condition of high speed cooling caused by inadequate. The solution is fully cooling, additional cooling. B, overload. Serious surface spalling and wear, shows that the rolling bearing early fatigue failure caused by overload ( In addition to cooperate too tight can also cause a certain degree of fatigue) 。 Overload can also cause a serious bearing steel ball raceway wear, large area of spalling and sometimes accompanied by overheating. The remedy is to reduce the bearing load or improve the bearing capacity. C, low corrosion of vibration load. In each ball appears on the axial position of the elliptic traces of wear, this shows that when the bearing is not work and did not produce lubricating oil film, caused by external vibration excessive or low load vibration failure. The remedy is to make the roller bearing vibration isolation or add anti-wear additives in TIMKEN bearing grease, etc.
