Ball bearings are usually divided into non-drinking stiffening stiffening bracket bearing two kinds. Non-stiffened damping rubber bearing only one ball bearing price, although at the level of force rubber bearings to meet the needs of shear deformation level, but bearing in vertical loads tend to produce vertical deformation. At this point, the ball bearings due to constraints is relatively small, and because the incompressibility of rubber, ball bearing deformation only sideways expansion, there will be a large rubber oil drum at a large convex pulling in around it stretch deformation, thereby generating stress aging. Such ball bearing on our roads and bridges is not recommended. In order to withstand large vertical loads can also meet the needs of horizontal displacement, the bridges are generally used stiffened laminated rubber bearings, ball bearings stiffening stiffening material can be steel, glass fiber, cotton, nylon cloth, single Our bridge stiffening materials used in steel, other materials not recommended, since as a stiffening plate rubber under vertical loads, steel embedded rubber sheet rubber between will limit the expansion of the convex side drum, vertical deformation is reduced accordingly, thereby greatly improved vertical stiffness rubber bearings. At this time, the ball bearing vertical deformation of the total deformation will be the sum of each thin rubber sheet. Rotational displacement for the upper structure of the resulting deflection. Produce a corresponding bump in the free side of the laminated rubber bearing ball bearing to withstand external force shown below, at any point within the bearing, rubber bearing that design load Effect of laminated rubber bearings and reliable performance ball branch Block, ball bearing with good elastic properties seismic ball bearing manufacturers, can reduce the impact of dynamic load effects on the structure and piers of the bridge span, thus improving the overall force and bridge seismic performance. Low height ball bearing construction (eg for steel bearings are generally small and medium span bridges height of 90 ~ 180mm elastic ball bearing supplier, while the corresponding laminated rubber bearing construction height of only 28 ~ 56mm) easy construction and installation and replacement. Ball bearing than the usual rubber bearings can reduce the power generated by the seismic displacement beam level, so from driving and seismic point of view, I hope to be studied in the future as far as possible from multi-span continuous development direction.
