Appearance flatness after assembly requirements, after sliding bearing assembly exposed surfaces smooth, beautiful, uniform welds, attendance plate should be parallel to the ground and lower seat board, parallelism should be no larger than the diameter or the long side of 2%, attendance plate centerline Under the sitting board centerline should coincide. Transport and storage, after sliding bearing assembly should be fixed, and transport, storage, and installation shall be arbitrarily removed, after assembly height deviation requirements. Corrosion, due to the hardness can not resist the acidic environment of the chloride ions and negative ions, and could easily be atmospheric ion erosion, especially in the supply environment, so to special protection, the sliding surface of the sliding bearing installation should be preceded by cleaning ball bearing hinges, particularly square value of the surface to be lubricated contamination. The basic provisions of sliding bearing design, according to the national standard spherical hinge finished two-way sliding bearings, sliding bearings with PTFE sheet, high quality grease lubrication conditions in contact with the spherical steel and stainless steel friction coefficient reduction in The average stress is 30mpa spherical hinge when finished slide bearing, the friction coefficient should be designed to meet the requirements under the concrete strength grade spherical bearings should generally not less than 40, the slide bearing pad type partial pressure area under a certain height range distribution within the multilayer arrangement reinforced to withstand the splitting tensile stress of concrete. Spherical bearing design principles, ball bearing design, bridge design in our country do not have your prescription request, do a very good presentation based on foreign experience and practical application. In the concrete cross-section of the hinge part of the neck should design the sliding bearing to prevent the portion of FIG Nanjing peeling under high stress, thereby generating tension split, and the split portion in tension will be the direction of the edge, the tension in this section should be reinforced to bear by the configuration, the stress state of the concrete hinges. As can be seen from the figure, the hinge necking ratio, the allowable pressure of the sliding bearings or allowable stress, the greater the angle of the hinge when the sliding bearing hours, through the concrete portion of the deformation of the hinge can rotate. And when the angle is large, the hinge portion of the concrete will crack necked spherical hinge slide bearing a quote, a sharp increase in the pressure of concrete at this time. Sliding bearings under sustained load cracks may be due to creep deformation of concrete partially closed, sliding bearings makes eccentricity and rotational reaction force is reduced, and therefore, in determining the permissible angular and rotational torque should be based on the dead load and live load circumstances be treated differently.
