Timken spherical roller bearings correct installation and use of the matters needing attention

Timken bearing before installation should be clean. When installed, you should use the special tool to auxiliary sell straight uniform pressure into the, don't use hammer percussion, specifically prohibit direct bearing on tap. When bearing race with a hole loose, should be to repair or replace the bearing seat holes, do not use on the surface of bearing with pitting or pad barely use copper method. Spherical roller bearing removal should be used when appropriate to pull pull the bearing, do not use a chisel, hammer percussion bearing, etc. Rolling bearing two kinds of commonly used lubricants lubricating oil and grease. When the peripheral speed of the shaft is smaller than 4 - 5 m/s, or the car cannot be used lubricating oil, lubricated by grease. Grease lubrication sealing structure of the method is simple, the grease is not easy to drain, little affected by temperature, plus a grease can use a long time. Use grease should pay attention to two questions, one is according to the requirements of the car manual, choose suitable type of grease. Auto water pump bearing, for example, unfavorable choose base grease, due to its poor water resistance. 2 it is to join in the bearing grease want right amount, generally only 1/2 - filling timken bearing cavity L / 3 advisable, too much not only useless, also can increase the running resistance of spherical roller bearing, warming heat. Paying special attention to the automobile wheel hub bearing, we must promote the 'empty hub lubrication', that is only in the layer of the tu yi on bearing can be just the right amount of grease, otherwise, not only waste and poor heat dissipation, still can make heat grease spillover, may affect the braking performance. Lubricating oil has the advantage of small frictional resistance, and heat dissipation, it is mainly used for the bearings of high-speed and working environment temperature is higher. Brand to choose according to the requirement of the car manual of lubricating oil, and car maintenance cycle change in time, released after the old oil is to add new oil after cleaning of institutions, oil should be added to the line, or refueling and flush ( Depending on the auto specific structure, requirements) , and not more. In order to prevent the timken bearing wounds during installation, in addition to the installation or removal in the process of using appropriate tools, use the punching machine to prevent the impact on the bearing load, and also note the mutual centering during installation. In order to avoid the bearing in the operation process, lead to equipment downtime, loss. Therefore, dealing with bearing completes the monitoring work. To do a good job in terms of bearing lubrication. If the spherical roller bearings have good lubrication, and cut off the right moisture and debris, the oil seal should not wear. Of course, the best when open the bearing box, check the bearing and periodically check the oil seal. Check of the condition of the near the bearing oil seal, make sure they are enough to prevent the hot liquid, corrosion along the axis of the liquid or gas infiltration timken bearings, if oil seal was worn, it should be replaced as soon as possible. When the bearing is in abnormal situation, usually manifested by high temperature. High temperature inside the bearing lubricant is harmful, and may also be a problem of lubricant timken bearing overheating. If the bearing in the long run of more than 125 degrees Celsius temperature, can shorten the service life of bearing. Therefore, to pay attention to the problem of bearing the high temperature. The cause of bearing temperature include: insufficient lubrication or excessive lubrication; Lubricant contains magazines; Too much load; Timken bearing damage; Such as high temperature friction and oil seal clearance. Normal working of spherical roller bearing ring should be uniform and smooth, not harsh voice instead of the normal working of bearing has a wide variety of intermittent, impact or harsh voice. First have to get used to the normal working of bearing ring, and then you can grasp the judgment is not normal working of bearing, and then through the accumulation of practical experience, and further can analyze what kind of what kind of bearing abnormal sound corresponds to the abnormal phenomenon. Bearing abnormal sound of category a lot, it is difficult to talk, mainly by experience accumulated.
