Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to a joint bearing node. Background Art
[0002] Centripetal spherical bearing nodes (with centripetal spherical bearings as the rotation center) have been widely used, and their application in steel structure buildings and bridges is a typical example. With the continuous promotion and application of spherical bearing nodes, the working conditions they face are becoming more diverse and complex. Figure 4 As shown, an existing spherical joint bearing node structure, its rotating part 2' can rotate in the plane relative to the base 1' around the axis A of the pin shaft 3', and the rotating part 2' can also perform out-of-plane twisting relative to the base 1' around the axis B (passing through the rotation center of the spherical joint bearing and perpendicular to the axis A) and perform out-of-plane tilting movement in the left and right directions relative to the base 1'. Since the radial spherical joint bearing has a three-way rotation characteristic, the existing spherical joint bearing node cannot only rotate in the plane and out-of-plane, but also inevitably undergoes out-of-plane twisting, which makes it difficult to meet the "anti-torsion" requirements under special working conditions.
