What details need to be paid attention to when flushing bolted roller bearings? Needle roller bearings are bearings that contain cylindrical rollers with a diameter smaller than the length. The tops of the rollers are slightly tucked to improve the line contact between the rollers and the dovetail guide. This avoids high-value ground stress on both sides of the needle roller, which in turn increases the bearing time. Although the cross-section of needle roller bearings is not large, their load-carrying capacity is very high. Therefore, it is suitable for bearing structures with relatively limited radial indoor space. Needle roller bearings can be divided into radial bearings and torsion bearings according to the orientation of the load. Among them, radial bearings include: stamping die outer ring type, solid core type, and special type anchor bolt type and flat washer type needle roller bearings of various series of products. Full complement cylindrical roller bearings without outer rings are designed to handle heavy loads. Under the same overall width, compared with the ancient bearing with ball bearing, this type of bearing has high bearing capacity and small radial cross section, which can save indoor space, but the speed ratio is relatively low. In order to better make the bearing work normally, in the state of connected operation, the bearing must bear a small load in the field, that is, C/P. Assuming that there are scratches, rust, abrasion, slag, gravel, dust and stains on the surface of the installation surface of the bolt roller bearing and the surface of the matching parts, it is very likely that the bearing installation part is incorrect; the second is the composition of such accessories Wear-resistant materials and the working surface of the easily worn bolted roller bearings can compromise the quality of the device. Therefore, ordinary industrial equipment will take precautions on the surface of the motor shaft, the surface of the bearing box cover hole, the surface of the inner rib of the shoulder and the matching surface of the matching parts such as the bushing, sealing ring, bearing end cover, etc., in order to stop production and processing seriously. carefulness. If there is a rust layer, it can be removed with a fine file and polished with a fine sand cloth. In addition to this, fittings on bearing component surfaces and mating parts must be cleared. The use of bolted roller bearings is a common problem: bearings are precision parts and must be used with relative caution. No matter how high-performance bearings are used, the predicted high-performance cannot be achieved if they are mishandled.
