Nantong seismic ball bearing hinges, strong technical force manufacturers, two-way sliding ball joint mount is provided by seismic HaoTong Engineering Rubber Co., Ltd. Hengshui. Nantong seismic ball bearing hinges, strong technical force manufacturers, two-way sliding seismic ball bearing hinge is Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) launched this new upgrade, the above picture is only for reference, please call this page or contact phone picture on to obtain the latest information, contact: Liu. When the corner angle ball joint maximum design earthquake ball bearing hinge bearing adaptation, the vertical displacement at the position corresponding to the top and, by universal rotation formula to determine seismic ball joint bearing, the largest design corner, pots ring diameter, pot ring width, steel plate side length, stainless steel plate and the top plate if welding connection type, ball bearing hinge welding requirements shall calculate the weld length, if only unidirectional stainless steel screws riveting ball slip earthquake Hinge Bearing required shear area can calculate the following formula. Bearing shear area shear screws, bearing design bearing capacity of two-way slip earthquake ball joint bearing, PTFE slide stress, PTFE slide area, PTFE slide design allowable stress, ball bearing hinges standard for 30mpa, tetrafluoroethylene skateboard diameter, other requirements designed other requirements designed ball bearing sliding surfaces hinge allows material combinations for PTFE plate and immortality steel, flat PTFE board should meet the requirements. PTFE slide bearings ball joints plane thickness, flat PTFE slide diameter PTFE slide ball bearing hinge projection height, tolerance is 0.2mm, when the error is 0.3 when measured in the calibration of the measurement point, and in Here anticorrosive coating thickness of less than 30mm, should at least have another measurement points and a reasonable distribution. Guides for embedded PTFE sheet, PTFE sheet guide groove for a minimum thickness of 5,5mm, projection height of 0.2mm in determining the need for lifting the total weight of the beam, analysis of the forces at each fulcrum, should be based on their specific situation, or have conditions permit is based on the design and construction drawings can not stress analysis to determine the approximate distribution of the load, according to what the distributed computing theory-forward top load hydraulic jack in said set quantitative analysis approach. But generally should be adopted when the total amount of the bridge-girder, the ball bearing hinge construction according to the Champions League empirical data, subjected to vertical loads from steel reinforced with stiffening rubber bearing stress state shown. Upper and lower ball joints stiffened steel plate bearing constraint bulging rubber ball bearing hinge between the two contacts to generate shear. According tension stiffening steel produced. Tension stiffening steel produced increases with the rubber sheet thickening estimated according to the following empirical formula; the total weight of the beam, construction bridge span in the sum of all the upper structure of gravity; constraint factor, ball bearing hinge theoretical calculation based on constraint conditions or determined by tests, bridges dynamic load, dynamic load coefficient. Taking into account the overall construction of a simply supported beam, vehicle dynamic load attenuation along the transverse direction, and each pivot point analysis supported bridge force be estimated according to the following.
