Detailed Product Description: | Specializing in the production of high quality seismic ball joints finished bearings, spherical fixed hinge bearing seismic, seismic finished bearings, seismic damping bearings, steel hinge bearings, steel damping steel bearing. Tel: 15075853136 Contact QQ: 1162984374 Contact: Cui a seismic ball bearing hinge finished construction features and functions QZ ball bearing slide by Theravada board, Xiazuo plate, convex shape of the intermediate plate and two different poly tetrafluoroethylene plate. Middle Xiazuo board for a spherical concave, convex corresponding with the intermediate plate, with a curved PTFE plate lining between the two, sliding to meet with them by rotating spherical beam end; stainless steel plate and intermediate plate Theravada Another integral PTFE plate on the completion of the second telescopic sliding surface displacement of the beam generated due to temperature factors. Ball bearing sliding force transmission reliable, consistent performance each to rotate, not only with pot rubber bearing load capacity, large horizontal displacement characteristics, and can meet the needs of a large corner, for wide bridge, curved bridge. Because of pressure parts do not use rubber parts, rubber and other effects of aging temperature brittleness does not exist, it is particularly suitable for low temperature areas. Second, seismic ball bearing hinge finished the main technical performance a sliding bearing reaction force (vertical bearing capacity) is divided into 16: 1000KN, 1500KN, 2000KN, 2500KN, 3000KN, 4000KN, 5000KN, 6000KN, 7000KN, 8000KN, 9000KN, 10000KN, 12500KN, 1500KN, 17500KN and 20000KN. 2, the slide bearing angle into 0.02,0.04,0.06rad. (Can be increased according to need) 3, the sliding coefficient of friction bearing design in grease lubricated PTFE board has under conditions of stress is about 30MPa, take values ??are as follows: room temperature (-25 ℃ ~ + 60 ℃) 0.03 low temperature (-40 ℃ ~ + 60 ℃) 0.05 4, sliding bearings can withstand the horizontal forces; unidirectional sliding bearing activities (DX) transverse to the horizontal force a sliding bearing fixed to the reaction force of 10% of the sliding bearing (GD) is subjected to horizontal reaction force of the slide bearings 10% Third, the finished ball joint bearing seismic advantages: the sliding bearing 1, the use of surface contact, the contact surface large, low pressure, mass force uniform, so small, small amount of steel. 2, sliding bearings, small size, low height, the mechanical calculation diagram is consistent with the overall calculation diagram, or reduce the error will not cause mechanical calculation model and the actual structure. 3, sliding bearing can be universal bearing, can withstand the pressure, pulling force, the size of any direction of shear force can be designed according to the requirements. General series of products for 500 ~ 80000KN. (In continuous girder bridge, curved bridge, large grid four corners and temporary load bearing generated when the construction will produce pulling force, other types of bearings can not withstand excessive pulling force and shear. 4, sliding bearings be universal rotation, internal ball dumplings, it can be universal rotation. corner size can design engineering requirements, sliding bearing rotation can generally (0.02 ~ 0.05) rad (radians). This feature is best suited for a wide bridge, ramp bridge (ramp bridge) and spatial structure of four, seismic ball bearing hinge finished an overall performance index, vertical bearing pressure: 500 ~ 800000KN 2: Vertical pulling force: 500 ~ 800000KN 3, horizontal shear: 500 ~ 800000KN These three types of force can be owners and project needs, selecting four free combination, design corner:. 0.02 ~ 0.06Rad (radians, equivalent to 1.140 ~ 3.440) 5 shift amount: (± 5 ~ ± 1500) mm, if special needs may need to design 6, Mount control coefficient:. μ = 0.03 (room temperature -250 ~ 400) μ = 0.005 (room temperature -600 ~ -250) 7, anti-seismic capacity: 7 to 11 degrees (by region and user requirements design) 8, the development of parameters, serialization of products to meet various technical requirements of different users, according to user requirements and design a map seismic ball joints finished bearings, spherical fixed hinge bearing seismic, seismic finished bearing, seismic damping bearings, steel hinge bearing, steel bearing steel damping |
