Spherical bearings are commonly used rolling bearings that have spherical outer and inner rings, as well as spherical rolling elements (usually steel balls) rolling between the inner and outer rings. The functions of spherical bearings mainly include the following aspects:
1. Support and guidance: Spherical bearings can support and guide rotating components on bearings, such as shafts, bearing seats, etc., so that they can move relative to each other and achieve normal operation of mechanical equipment.
2. Reduce friction: Spherical bearings work in a rolling friction mode, with spherical rolling elements rolling between the inner and outer rings. Compared to sliding bearings, friction is smaller, which can reduce energy loss and wear.
3. Load transfer: Spherical bearings can withstand radial, axial, and composite loads from rotating components, and transfer the load to the bearing seat or support structure, thereby maintaining the stable operation of mechanical equipment.
4. Vibration absorption: During mechanical movement, spherical bearings can absorb and reduce external vibrations and impacts, protecting mechanical equipment from damage.
5. Positioning and adjustment: Spherical bearings can be used for the positioning and adjustment of mechanical equipment. By adjusting the position of the bearing seat or the bearing itself, precise positioning and adjustment of mechanical components can be achieved.
Overall, spherical bearings are a common type of rolling bearing that have functions such as support and guidance, friction reduction, load transmission, vibration absorption, positioning and adjustment, and are widely used in various mechanical equipment and engineering fields.
