Zaozhuang Bearing, Zaozhuang 3..3. Slewing bearing / ' (3,3,3) -Six major differences between slewing bearings and rolling bearings:
/ ' (3,3,3) -[], Normally , the slewing bearing is equipped with a ring gear for rotational driving and a dust-proof sealing device. These devices play an important role in ensuring the normal low-speed and high-load operation of the slewing bearing.
【】The size of rolling bearings is generally relatively small, while the size of slewing bearings is larger, with diameters usually in meters, and some slewing bearings even have diameters as large as meters. Of course, this special case is less common.
【3】In terms of operating speed, compared with rolling bearings, the operating speed of slewing bearings is lower, usually below rpm. In many situations where bearings are required to roll, the slewing bearing does not operate continuously, but only rotates back and forth within an angle, which is equivalent to the so-called swing bearing.
/ ' (3,3,3) -[], the installation methods of slewing bearings and ordinary rolling bearings are different. The slewing bearing is not mounted on the spindle and installed in the bearing box like ordinary bearings. Instead, it is fixed on the upper and lower supports with screws.
【】Slewing bearings generally have to bear loads from several aspects, not only axial force and radial force, but also large overturning moments. Therefore, a set of slewing bearings often functions as several sets of ordinary rolling bearings.
【】, There are big differences between slewing bearings and rolling bearings in terms of materials, heat treatment and other manufacturing processes. The above are the six differences between slewing bearings and ordinary rolling bearings. Understanding the differences between these bearings will play a positive role in the production and application of enterprises. Only by selecting bearings suitable for enterprise production according to needs can the bearings play their maximum industrial role.
