Ball bearings as an effective bridge structure damping device has been applied abroad bridge device. Vertical stiffness, bearing good performance, supported bridges can stabilize the upper structure, moderate levels of stiffness, which can meet the earthquake generated large displacement. Better performance, ball bearings have the energy absorbing seismic ground brought a large earthquake resistant ball bearing life expectancy under normal circumstances can reach 50 years. Spherical plain bearings are squeezed into a laminated rubber bearings with lead or multi-pin, a bearing structure in order to improve the performance of rubber bearing structure. LRB withstand the weight and horizontal forces of the bridge structure, lead lag pin can produce plastic deformation to absorb energy and to provide horizontal restoring force by rubber, therefore, shot type support both isolation but also has a good effect function, type of bridge structures to improve the seismic zone seismic rating of an ideal seat form. The general structure of rubber bearing structure is simple, according to the Japanese zodiac signs bearing design standards related to damping provided by said pressure is 1500 ~ 2600kn the LRB bearing design and production of finished products. Almost does not allow this type of ball bearing angle or corner damping simply not allowed to have a spherical bearing, when used to pay special attention, while a permanent basis for the use of different forms of stress, often in the form of two-way movable damping Spherical Bearings carrying capacity of the plate width relationship. Such rubber bearings used in long-span structures over 6m, but you can use a certain angle requirements, rubber bearing bi-lateral slip reduced by between two Styrofoam plates embedded in a 5mm thick resistance elastic core blocks shock spherical bearing, the main role of the core blocks are as follows: (1) a load in the seat center. (2) ball bearings to absorb rotational deformation, preventing strain transfer to the lower edge of the structure, which can reach to avoid damage to the cracks and corners. (3) The ball bearing can absorb such a displacement of 2.5mm ball bearings are generally two kinds A and B form, in which A is a slide-type structure, and the structure of the two B-type slider, the upper surface Activities lined with polystyrene foam cushioning bi-spherical bearing, structure and parameters of such a ball bearing. Bearing a fixed or sliding point of contact when the contact point bearing, ball bearing can absorb the displacement of the contact point and to each of the displacement and rotation, to ensure uniform distribution of the load, such a ball bearing is often used residential and process buildings, parking and appearance of complex structures.
