Characteristics and priority application of SB series spherical bearings
There are differences and connections between all kinds of bearings (spherical bearings). For example, ation of SB series spherical bearings.There are differences and connections between all kinds of bearings (spherical bearings). For example, SB series of outer spherical bearings are actually a variant of deep groove ball bearings (spherical bearings), so their shape is different from deep groove ball bearings, but the basic performance is similar. So where is this kind of external spherical bearing suitable for use?
From the view of structure, (spherical bearings) the characteristic of SB series outer spherical bearing is that the outer diameter surface of the outer ring is spherical, which can be fitted into the corresponding concave spherical surface of the bearing seat, so as to play the role of adjusting the center. But its basic performance is similar to deep groove ball bearings, but even so, SB series spherical bearings are often used in rough machinery.
In practical application, the installation and positioning of the SB series of outer spherical bearings are often not accurate, and the axis of the shaft and the seat hole is not good for neutrality. Especially when the axis of the outer spherical bearing is long and the deflection is large and the precision of the bearing itself is not high enough, the actual performance of the bearing is not satisfactory.
Therefore, it is generally possible to arrange the bearing of the outer spherical surface to the simple situations of the equipment and parts, such as the agricultural machinery, the transportation system or the construction machinery. Here, it can be used to bear the radial and axial joint loads based on the radial load, but it is not suitable to bear the axial load alone.
Not only that, when the SB series of the outer spherical bearing is used, it is not allowed to tilt the shaft relative to the outer shell, otherwise the additional axial force will be produced under the radial load appointment. As the axial clearance of the bearing has a great relationship with the normal work of the bearing, it is necessary to pay special attention to the adjustment of the axial clearance of the bearing when it is installed and run, and it can be prefabricated when necessary to increase the rigidity of the bearing.
