Ball bearing hinges | HaoTong finished Sales | grid ball bearing hinge is Hengshui HaoTong Engineering Rubber Co. (www.htgcxj.com) this year launched a new upgrade, the above picture is only for reference, please call this page or Tel picture on to obtain the latest information, contact: Liu. Rubber bearing basin due to the vertical force children to do the radius of the spherical bearing and spherical difference made very small, can withstand greater reaction force, but in the rotation will be in contact with the sliding surface, then often in the sphere of contact Problems arise at the ball joint mount card at the grid, but this pot rubber bearing corrosion problems also exist relatively large. Furthermore, because such rubber bearing basin in the horizontal direction does not allow any type telescopic can use as a fixed bearing, attention should therefore be used in a wide bridge and caused adequately studied. Rubber bearing basin is unknown seismic cylindrical hinge between the Theravada ball bearing hinge plate and the lower bearing plate, usually unidirectional turning type of fixed bearing. According hinge support is divided into two kinds of support type and shear. While focusing on rubber bearing basin can be considered as the arch bridge, pier foundation and rigid frame viaduct pier hinge use, but be aware of this when the transverse bearing structure to a structure not allowed. When designing rubber bearing basin, we must fully understand the entire bridge abutment in the role, rubber bearing basin is important to connect the upper part and the lower part of the structure of the bridge structure, it must have the following main bridge support role and functional requirements. (1) must be able to support lateral loads from dead loads, live loads and other vertical seismic and wind loads and passing the upper structure, and secure courier to the substructure (piers, Taiwan). (2) rubber bearing basin horizontal displacement of the upper structure must be adapted by the live load and temperature changes and produced by the deflection angle displacement fulcrum. (3) In order to improve the entire bridge during an earthquake seismic performance ball joint bearing, bearing should have a damping and isolation of new energy, namely in the earthquake and wind (wind units) under the effect of having to adapt to the instantaneous LARGE role. (4) rubber bearing basin with the installation, replacement and maintenance convenience. (5) rubber bearing basin has a buffering effect in the vehicle role. Rubber bearing basin low height buildings (eg for steel bearing on the general height of the small and medium span bridges for 90 ~ 180mm, experimental study of the highway bridge rubber bearing basin mechanical properties, rubber bearing basin is mainly to development and revision of the highway bridge design specifications and provide a reliable basis for the transportation industry standard two conducted several experiments and other studies using line contact roller bearings, rolling friction of steel and steel, rubber bearing basin in addition due to corrosion and injuries, pot rubber bearing friction coefficient than the design value of expected large external unidirectional sliding ball joint bearing, rubber bearing basin injuries affect the level of movement and rotation functions are also a lot of rubber bearing basin but the contact precision surface is difficult to control, the situation is in contact with the line bearing the same injury a lot, so when pot rubber bearing calculation to determine the coefficient of friction is important to note this. By the early 1980s, rubber bearing basin appeared in China for nearly ten years with the application of history, rubber bearing basin and has been widely used in roads and bridges, but in the bridge design specifications related to the design of laminated rubber bearings rough calculation of the contents of the specified rubber bearing basin while the corresponding laminated rubber bearing construction height of only 28 ~ 56mm), ease of construction, installation and replacement.
