Cooperate with the surface of bearing assembly and parts, such as bleeding, surface corrosion layer, abrasive dust, sand, dirt, Dewey, and are difficult to install bearing assembly position is not correct; Two battles ErZe education is easy to wear and job losses mount on the surface of bearing assembly quality. Therefore, in the end face neck cushion installed to the shell surface edges and sleeve parts, washers, plate, and examined the mating surface. Such as rust layer, usable fine sandpaper file, interrupt, and remove parts surface and bearing assembly connection.
Bearing use
Note: the use of rolling bearing is precision components, but also need to be cautious accordingly. Anyway, if you use the improper use of high performance bearing without getting expected performance. Bearing use relevant considerations are as follows:
1) keep the bearing and clean surrounding. Even if the eyes can't see the little dust, will also affect the bearing. In order to keep clean, no dust, around the bearing.
(2) the use of. Be careful. When used, the bearing has strong impact, leading to depression scar and accidents. Severe cases, the crack fracture, so must pay attention to.
3) management tool. Use a success. Avoid to use existing tools and associated tools. Such as special glass, news, etc.
4) pay attention to the bearing corrosion. Because the operation of hand will cause of rust. Pay attention to the hand, it is better to wear gloves operation.Effect on rolling mill bearing quality damage judgment http://fagbearings.zohosites.com/blogs/post/Effect-on-rolling-mill-bearing-quality-damage-judgment/
5) didn't finish the work before installation, don't damage the bearing packing, in order to avoid pollution.
Considering load factors on the bearing rotating speed should be paid attention to life more sensitive than goods, so, if you like, the shaft of multiple reduction is more likely in some later; If the bearing load distribution and possible and pivot bearing, makes every effort to reduce the axial spacing and goods, and strive to achieve smooth bearing load, avoid shock and vibration, the need to install the bearing parts of the shape and location accuracy is high enough, games, and cooperate with the correct bearing installation precision is good.
In calculation of design model selection of load bearing, bearing may be wood wood payload at work, the calculation results correctly, therefore, widely effective load case and needs to be further studied.
If the bear big load and bearing static don't spin, this system is more negative, between roller and raceway form tiny fingerprints and soon became the feed point, bearing early faults. In this case select need monitoring bearing static load rating, can be more than the equivalent static load bearing.
Other extreme case, by contrast, high-speed bearing natural but not risk, part of the roll body, instead of sliding belt scroll, lead to bearing temperature rise rapidly, decomposition, bearing lubrication failure, so recruiting is to prevent the skid minimum load bearing.
In many cases because of the influence of vibration and bearing load increased significantly, the actual installation error of bearing alignment is not more than () also increases the bearing load, the actual calculation need to download the necessary correction.
Should also be considered in some cases, the axial and radial force produced by the device itself, the shaft parts, the weight of the weight, even after the stress calculation of bearing load, the load of often neglected, but only through the leak.
