By striving for the ultimate limit state and serviceability limit state design, to ensure there is sufficient stability against sliding, ball bearing hinge pot usually employ seat anchor system to ensure its stability, and support for a stable friction alone two-way sliding seat seismic ball bearing hinges, should the ultimate limit state checking its stability against sliding. Characteristics and the safety factor between steel and steel are generally used for checking the friction coefficient, there is a reasonable amount of displacement of the surplus, the surplus amount, whichever rotating hinge large. Slide the surplus amount of vertical and horizontal 20mm, maximum sliding direction, horizontal 20mm, this provision only for the displacement of the ability to design, can not be used to calculate the stresses. Minimum displacement ball bearing hinge strength design, large rotation, rotation bearing basin has its range of use, national standards limiting the pot bearings have the largest turn angle, ball bearing hinges are now mostly provisions should be no more than a single European standard of not more than 0.03rad, permanent relationship variable angle corner, the ball bearing hinge worth here permanently corner after corner-mounted front cradle initial operations caused by the dead load, it can be said corner, and live load operations generate relations between the corner. Design maximum angle, initial angle, the maximum angle ball joints unidirectional sliding bearings produced variable load, variable load generated by the smallest corner. Ball bearing hinge design, subject to the following conditions are generally controlled. In the role of the most unfavorable combinations of maximum corner, this value should comply with the standards prescribed or given by the design. Therefore, the ball must be maintained regularly to clean the hinge support ministries, to be painted scroll bearing lubricants, ball bearing hinge combination even tighten the bolts, there are serious shortcomings in the timely replacement of the rocker shaft bearings should even skew or tilt correction position avoid rolling surface is blocked and so on. Ball bearing hinge routine maintenance, bearing components are motorized ball bearing hinge bridge under live load, temperature changes or other factors, to produce rotation, horizontal displacement, are key parts of the conservation of fixed seismic ball bearing hinge taking into account the previous design of roads and bridges, is largely the work of conservation is not set bearing channel, ball bearing hinge bearing maintenance personnel inaccessible site, is to produce long-term conservation is not timely dystrophy, affecting the normal operation of the bridge . So stressed Jiaqing for bearing maintenance, channel maintenance work to solve the problem of the working platform is necessary, therefore, ball bearing hinges in provisions for routine maintenance of the proposed bridge bearing a few requirements. Supports various components should be kept intact, clean, sweeping at least once every six months, oil and ball bearing hinge around, garbage, prevent water, snow, ensure the normal operation of the bearing. Fixed seismic ball bearing hinge, ball bearing hinge, how much the price of the finished product? Advisory provided by Hengshui Hao-Hao Tong Rubber Company. Hengshui Hao-Engineering Rubber Co.
