Ball bearing hinge situation contact force design value, on top or intermediate steel surface contact strength design value, the material partial coefficient recommended value, the value of the cylinder inner basin ring contact surface curvature radius, design elastic modulus, rotational geometry required for The basic role of the combination, shall meet the following requirements, on the roof or intermediate steel plate with rubber elastic precipitation edge of the contact surface in a cylindrical tank should be closed along the entire perimeter of the basin formed by the bottom ring, ball bearing hinge neither from pots Central Corridor universal ball joints bearing edge, the top wall and the bottom bowl ring should not contact any metal component, subject to the following conditions in order to meet the above conditions, the ball bearing hinge effective height of the bottom bowl rings, rubber sheet elastic material thickness, on the roof or in the middle of the plate and bowl ring contact height, the height of the roof or intermediate plate in contact with the basin ring surfaces, maximum design angle. Ball bearing hinge inner bottom ring diameter pots, plates on the top surface of the roof or intermediate diameter, the amount of surplus material design elastic modulus, the design value of horizontal force, surface contact area radius universal ball bearing hinges, variable effect generating corner. Steel plate stress ball bearing hinge design or design reaction force bearing capacity, steel floor area, the steel plate side, steel plate material allowable stress elastic damping universal ball joint bearing, steel plate material strength standard value, itemized security Coefficient recommendations. Ball bearings from the case hinged on the highway bridge in recent decades used, in addition to the transportation industry standards set forth in species, there were a few varieties rebate fulcrum bridge superstructure beyond industry standards for 150 ~ 8000KN of bridges, more commonly used ball bearing hinge. Ordinary laminated rubber bearings for smaller bridge spans and small displacement PTFE slide rubber bearing suitable for large-span, continuous multi-span bridges, Charpy and continuous slab structures such as large displacement of the beam, it can laminated rubber bearings used as sliders and other small push and continuous beam T-beam traversing carriage used is usually divided into two non-stiffening stiffening drink holder. Only one non-stiffening rubber bearing, in effect, although horizontal force H bearing shear deformation meet the needs of a ball joint mount but in the role of the vertical load bearing R tends to produce vertical deformation is not recommended Other materials seismic rotation bearing universal ball joints, ball joints stiffened laminated rubber bearings under self-made vertical loads, steel embedded rubber sheet rubber between will limit the expansion of the convex side drum, vertical deformation is reduced accordingly, thus greatly improved vertical stiffness universal ball bearing hinge bearing _ buying the finished bearing find Hengshui HaoTong _ Steel Ball Hinge Supports provided by Hao-engineered rubber.
