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 ring contact surface curvature radius basin seismic hinge pin hinge design elastic modulus, rotation geometric conditions required for the role of the basic 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 joints Neither seat ring from the basin edge, the bottom wall of the top ring basin there should not be in contact with any metal components, 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, intermediate plate and the top plate or bowl ring contact height, the height of the roof or intermediate plate and bowl ring contact surfaces, maximum design angle. Ball bearing hinge ring diameter inner bottom basin, corner plates on the top surface of the roof or intermediate diameter, the surplus amount, the elastic modulus of the material design, the design value of horizontal force, surface contact area radius, variable effects produced. 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 hinge pin hinge, steel plate material strength standard value, safety factors recommendations. Ball bearing hinge vertical bearing capacity of the test, pot bearings vertical bearing capacity of the test, the general test load shall be 1.5 times the vertical load who, when the test will be placed in the pot bearing testing machine bearing plate center position, In the test seat four symmetrically placed around its vertical Yasu Austrian dial indicator measuring deformation and basin ring radial deformation was measured using four dial gauge, test equipment, the test damping hinge pin hinge, first pre- pressure, ball joints load bearing preload is generally spherical hinge bearing vertical design load, preload 3 times appropriate, conduct real load after preloading, the test loads from zero to the test load evenly divided into 10, When tested to the design load of 0.5% or 1% as the initial pressure, and then progressively loaded, read the dial and dial gauge data after each stage of loading the ball bearing hinge elegant 2min, until the test load, the regulator after 3min uninstall and measuring the residual deformation, the loading process by contacting three times, the ball bearing hinge vertical compressive deformation dial indicator readings were taken four arithmetic average of the fixed hinge pin hinge, draw vertical pressure ring radial load deformation curve, Typical load-deformation curve. Vertical compression ball bearing hinge design load shall not be greater than 2% of the total height of seat, basin ring radial deformation is not greater than 0.05% pots ring radial diameter.
