Hao-engineering rubber, KQGZ seismic ball joint bearing manufacturers, seismic ball bearing hinge is provided by Hao-engineering rubber. We are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) located at: Hebei Hengshui specializes in: grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, spherical steel bearing brass ring opening by 2-3 layers rings, diameter steel pots and press molding, the site should be re-assembled brass ring excuse evenly arranged along the periphery of bearing steel pots, cross-sectional size and number of seals. Ball bearing hinge mainly commercial roof, PTFE slide, middle plate, brass seals, rubber sheet, bottom basin, bolt, pillar, rubber gaskets and other components. Two months after passing inspection process but not assembled. Before the ball bearing assembly iron hinge pins on the Xiangjiang parts, burrs, oil sand and other debris cleared away, will be on the roof, under the bottom pots were painted and dried. When assembled, the ball bearing hinge rubber sheet with Teflon first skateboard clean the rubber plate placed between the bottom of the tank basin, the basin should be evenly bottom layer of grease. After installing rubber sheet, rubber sheet suppliers favorite surface is also spread a layer of grease, then put in the middle plate, the director of steel on PTFE slide into the slot. And oil storage tank filled with grease (currently used grease) and then installed on the roof (in the assembly process at any time to clean oil and impurities, and strictly control the mounting accuracy of each component) of the total height of the slide bearing seismic ball last inspection hinge bearing, ball bearing hinge all packaging factory or warehouse to store after passing the ball bearing assembly hinge height deviation control in general vertical bearing capacity of less than or equal 2000kn, the deviation is less than 3mm, the vertical bearing capacity greater than 20000KN , the deviation is less than 4mm appropriate, manufacturing processes ball bearing hinge products, ball bearing hinge basin child should do product requirements and general requirements for rubber block must do, are indispensable, the process summarized. Steel pots ring ring stress Checking tension of steel pots, the design level of internal forces, the design level resistance, rubber sheet pressure generated by the seismic design of radial KBQZ wholesale ball bearing hinge design vertical force, rubber plate design thickness, horizontal force design internal forces, longitudinal horizontal force generated by internal forces generated design, ball bearing hinge design internal forces transverse horizontal forces generated compressive strength steel standard values, partial safety factors, the recommended value, rubber board area, bottom basin ring diameter, bottom basin ring diameter, ball bearing hinge bottom basin ring height, steel pots withstand shear ring. Bottom basin ring withstand shear design value, the bottom bowl ring design value of shear strength, design radial compressive force generated by the ball bearing hinges, rubber sheet level to produce shear design value, the compressive strength of standard steel ball bearing hinges values, partial safety factors, the proposed value of 1.10, the bottom basin ring diameter, bottom diameter pots yellow, steel bottom plate pelvic floor tension design value, the tensile strength of steel at the end of the pelvic floor plate design value, ball joint reaction force design value, steel compressive strength of the standard value, the design strength of the allowable value is generally taken to be 140mpa, sub-factor of safety items. Pelvic floor plate steel ball bearing hinge ring to the area outside the ring diameter steel pots, steel plate thickness of the pelvic floor, on the roof or in the middle and bottom steel bowl ring contact checking, assuming that the width of the roof on a fast connection surface KQGZ seismic ball joint bearing manufacturers, So manufacturers roof or intermediate bottom and the bottom bowl ring contact surfaces can be designed to average mechanical resistance ball joint bearing contact surfaces should be the fundamental role of a combination of authentication. Planar contact surface checking. Plane contact force design value, roof flat contact on the ball bearing hinge design value seismic intensity ball bearing hinges, the compressive strength of standard steel material analysis coefficient values ??recommended value, the steel basin ring diameter, the height of the ceiling height in contact with the pot ring , curved contact surface of the radius of curvature R
