Press the ultimate limit state and to limit state design striving to ensure that there is sufficient stability against sliding, ball bearing hinge pot usually use anchoring system to ensure its stability damping bearing ball bearing hinges, and stable bearing friction alone shall be the ultimate limit state checking its stability against sliding. Between the features and the safety factor is generally used for checking steel plate and friction coefficient, there is a reasonable amount of displacement of the surplus, the surplus amount, whichever rotating hinge great. Slide the surplus amount of vertical and horizontal is 20mm, maximum sliding direction, universal transverse 20mm slide ball bearing hinge, this provision only for displacement ability to design ball bearing hinges, can not be used to calculate the stress. The minimum displacement ball bearing hinge strength design, turn volume, turn the pot bearing has its certain range, national standards limiting the pot bearings have the largest turn angle, the ball bearing hinges are currently mostly provisions shall not be greater than a single European standard of not more than 0.03rad, permanent variable relationship corner corner, the ball bearing hinge worth here permanently corner after corner before the initial installation operations due to stand, it can be said that the dead load corner, with live load operations generate relations between the corner. Design maximum angle, initial angle, the maximum angle variable load generated by the smallest corner of variable loads generated. Ball bearing hinge design, generally controlled by the following conditions. In the role of the most unfavorable combinations of maximum angle, this value should comply with the standards prescribed or given by design. Ball bearings from the case hinged on the highway bridge in recent decades used, in addition to the transportation industry standards set forth in species, there have been some fulcrum bridge superstructure rebate varieties other than those specified industry standard for 150 ~ 8000KN of bridges, more commonly used ball bearing hinge. Ordinary laminated rubber bearing for smaller bridge spans and small displacement PTFE slide rubber bearing suitable for large-span, continuous multi-span bridge, Charpy and continuous plate structures such as large displacement of the beam, it can laminated rubber bearings used as sliders and other small push and continuous beam traversing T-beams used is usually divided into two non-bearing stiffeners stiffening drink holder. Only one non-stiffening rubber bearing, in effect, although bearing horizontal force H level to meet the needs of shear deformation, ball joints but in the vertical load bearing R role holder will often produce vertical deformation is not recommended Other materials seismic ball joint bearings, ball joints stiffened laminated rubber bearings since made under vertical loads, steel embedded rubber sheet rubber between will limit the expansion of the convex side drum, vertical deformation is reduced accordingly, thus greatly improving branch Block vertical stiffness universal ball joints bearing bearing capacity 1000KN, damping hinge ball bearing HaoTong professional wholesale agents provided by Hao-engineering rubber.
