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, fixed hinge bearing test apparatus, the test finished fixing pin hinge, first pre-press, ball joint bearing preload is generally spherical hinge load 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 level, 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 bearing fixed hinge Which is good, after the regulator 3min uninstalling and determination of residual deformation, the loading process by contacting three times, the ball bearing hinge vertical compressive deformation dial indicator readings were taken four arithmetic mean, draw vertical pressure ring radial load deformation curve, the 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. Ball bearings and horizontal bearing hinge ball bearing hinge non-slip direction shall not be less than 10% of the vertical bearing capacity, seismic bearing horizontal bearing capacity of not less than 20% vertical bearing capacity, and can withstand not less than vertical to the 20% uplift bearing capacity. Ball bearing hinge is not applicable temperature range, bearing physical and mechanical properties of materials used PTFE sheet, PTFE sheet PTFE fixed pin hinge plate bearing the force used should be used fresh, pure molded material, you can not use cutting boards, you should not use recycled materials, back material embossed sheet, together on the average particle size PTFE sheet material shall not be greater than 50mm, molding pressure should be less than 30mpa PTFE plate The physical and mechanical properties. Monumental steel ball bearing hinge used, the use of materials such as technical conditions are met adjustable ball joint bearing, tension and compression drink holder designed to be used on the bridge seismic zone basin seismic rubber bearings, spherical bearings and lead pin earthquake rubber bearings, etc., these are almost always the patented product, it can be expected soon will be valid for use on bridge engineering, while monitoring the quality of bridge engineering work has also been strengthened, the experimental study of the dynamic performance of ball bearing hinges also In emerging to make better meet the needs of the bridge abutment of highway bridge construction. _ Purchase of fixed hinge bearing pictures Hengshui Hao-quality products (certified) _ fixed hinge bearings provided by the Engineering Rubber Co., Ltd.
