Prevention of TIMKEN bearings configuration actions need to pay attention to what matters

Although bearing is metal, but can also damage, whatever the hardest substance will damage, the extent of the damage is not the same, we all know that the fine quality of the bearing are good steel manufacturing, steel is a very solid material, but also can damage, wheel bearings in mechanical running everyday, friction, it is easy to damage the bearing, so we also want to prevent bearing damage, well bearing maintenance, don't want disorderly use bearing, to cause unnecessary losses. TIMKEN bearing is to ensure that produce too much deformation when installation, and from these aspects need to be done, for bearing need to do have a lot of, the following will introduce about it need to be aware of the effect. 1) , shaft and hole of the roundness, and retaining shoulder perpendicularity to according to the corresponding precision of bearing requirements. 2) , as well as the calculation of the rotating ring with quantity, also to accurate calculation of the fixed ring with right quantity. The rotating ring burning interference quantity within may also should be made smaller. As long as to ensure that work under the temperature of thermal expansion effect, and under the maximum speed of centrifugal force effect, not cause peristalsis or sliding on the surface of the tight fit. Fixed ring according to the size of the working load and bearing size, choose the smallest clearance fit or interference fit, too loose or too tight is unfavorable to keeping the original precise shape. 3) , bearings, such as under the condition of high speed operation and high working temperature, should pay special attention to the matching of the rotating ring is too loose, to prevent the eccentric vibration, and the matching of the fixed ring is a gap, in order to prevent the ferrule deformation and vibration under load. 4) , on the condition of fixed circle take transgressions surplus to cooperate is suitable on the surface of both sides have a high shape accuracy and smaller roughness, cause otherwise in installation and removal harder, in addition, also need to consider the influence of the spindle thermal elongation. 5) , the use of double angular contact ball bearing of the spindle in pairs, for the most part load lighter, its interference such as large amount, the amount of axial preload is its internal significantly larger, causing adverse effects. Using double row short cylindrical roller bearing of the spindle and wheel bearing of the spindle, the load is opposite bigger, so its interference also relatively large. From the Angle of rotation to consider, TIMKEN bearings in the aspect of configuration is to notice the above situation, but the temperature is not stable, these are to consider the main aspect is the device wheel bearings how to cooperate with it.
