Spherical bearings are mainly used for shock absorption and load-bearing functions in bridges and buildings. As one of the four major mechanical structural bearings, it has become an ideal shock absorber through its unique spherical contact surface design. Ball bearings originated from rubber bearings and are highly sought after in many low-temperature environments due to their avoidance of rubber hardening and aging issues.
The structure of spherical bearings
As a new type of bridge bearing, it fully utilizes the spherical characteristics, and the main structure – spherical polytetrafluoroethylene sliding plate is responsible for friction with the core spherical crown lining plate to ensure flexible steering; Silicone grease is made into oil storage pits through specialized molds and applied to the surface of PTFE plates to reduce friction during sliding and minimize losses caused by sliding; The sliding plates of the upper and lower supports are the same as the bowl type supports, which meet the displacement of the supports in various directions.
Advantages of spherical bearings
Spherical bearings have the advantages of flexible rotation, high load-bearing capacity, and large turning angle. Spherical bearings transmit force through the spherical surface, and the reaction force to the base concrete is relatively uniform, achieving good unloading effect. The rotation of the support is achieved through the sliding of a spherical surface, which is suitable for the requirement of large rotation angles. And there are no factors affecting rubber aging, making it suitable for use in low-temperature areas.
