Between the rubber sheet is embedded in the rubber layer to prevent lateral expansion convex drum, while the ball-type bearing shear stiffness had little impact at the level of force H effect, the amount of displacement produced rubber bearing and non-stiffening rubber support Block, roughly the same level of deformation. Ball bearing similar bridges generally use several layers of thin rubber sheet and stiffener plate for stiffening rubber bearings, ball bearings, the finished product is between the layers of rubber sheet with adhesive coated by a thin steel in the mold pressing a vulcanized integral structural configuration. Displacement of the ball bearing and bearing only the net thickness of the rubber layer, and the other, in order to prevent corrosion stiffening steel, ball bearings on the stiffening rubber bearing, below and around the rubber has a certain thickness of the protective layer . Transportation industry standard "roads and bridges laminated rubber bearings" (JT / T 4-2004) of provisions for ordinary plate and rectangular and circular rubber bearing laminated rubber bearing given the specific structural configuration shown. The amount of ball bearing ball bearing too much one-way activity, affecting the quality factor and great, so you can not put a lot more work ahead of yellow rubber bearings for posterity ball bearing isolated one-way activity, although the design considerations measures to check the activities of replacing ball bearing DX, but so many replacement bearing plate system call that is no small task, therefore, the ball bearing bridge design should put a good man and expensive first hurdle. In revising the bearing industry norms and standards of bridges and culverts, the project team for disposal information and international standards, foreign as well as domestic standards for all willing to achieve the relevant technical levels were fully reflected, revised standards, and norms solicit Bright system design, construction, production, management and the opinions of experts, also sought the views of system-level detection and municipal quality supervision activities damping unidirectional ball bearing, manufacturers opinion. A type of ball bearing type belong rubber bearing, in earthquake-prone areas must consider earthquake building bridges so that when the local earthquake can make a bridge to maintain its function, so as to ensure the smooth progress of relief and post-earthquake work. Reduce the losses caused by the earthquake, the ball bearing damping design, rubbing the bridge structure can support up and ball bearings to make structural vibration in the long period of the same time, by LRB dissipative vibration energy, thereby reducing damage to the bridge structure seismic crews. Unidirectional activity ball bearing, professional manufacturers, shock-way ball bearing activities provided by the Engineering Rubber Co., Ltd. Hengshui HaoTong.
