Ball bearing hinge vertical bearing capacity of the test, the pot bearing 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 central location, In the test stand symmetrically placed around the dial indicator to measure the vertical Yasu four Austrian deformation and basin ring with four indicator measuring radial deformation, test equipment, the test seismic ball bearing hinges, first pre-press, load bearing preload ball joints ball joints generally vertical design load bearing preload 3 times is appropriate, conduct real load after preloading, the test load from zero to test load evenly divided into 10, when the test After reading the design load to 0.5% or 1% as the initial pressure, and then progressively loaded ball bearing hinge 2min each stage of loading elegant dial and dial gauge data, seismic grid until the test load ball bearing hinges, Regulators 3min after uninstalling and determination of residual deformation, the loading process by contacting three times, the ball bearing hinge vertical compression dial indicator readings were taken four arithmetic mean, draw vertical pressure ring radial load deformation curve, typical The load-deformation curve. Vertical compression ball bearing hinge design load shall not exceed 2% of the total height of seat, basin ring radial deformation shall not exceed 0.05% pots ring radial diameter. Because the oxide film and the phosphate film also has a protective effect, so that the basic surface to form a protective film, because Yang Ha film and phosphate may enhance the adhesion of the coating and the metal, and there is a very good Chinese Lin Hua and phosphorus truss of better seismic ball bearing hinges, high temperature phosphate phosphate coating, ball bearing hinge Chinese phosphate and phosphate low points, and high temperature phosphate and Chinese phosphate better. Ball bearing hinge phosphate coating enhances the adhesion of the coating and the metal ball joint bearing seismic corridor, but also a very good corrosion resistance and heat resistance, corrosion for demanding components, for further protection Tsang capacity, available collateral acid passivation seat Xie Rong, ball bearing hinges often become complex, post phosphate is completed, should be required to protect the ability of steel parts before painting the phosphating treatment under enhanced. Ball bearing hinge on phosphate coating quality testing, failure mostly due to general corrosion caused by unqualified phosphate coating for aluminum and its alloys, degreasing, descaling institutions, should be anodized immediately. Through the years or decades of bridge operations, ball bearing hinge inevitable aging, deformation, dislocation caused by uneven slab and tilt, causing vibration and impact force increases, resulting in damage to the telescopic device, knocking pain jumping, ball bearing hinge seriously affect the carrying capacity of the slab.
