Ball bearing hinges, by sliding plate and elastomer composition supporting circular basin fathers, ball bearing hinge only Xiazuo elastomer insert groove side panels as intermediate dry plate with a sealing elastomers, in the middle of steel projecting on the intermediate steel plate embedded in a structure constructed above the plate and the upper seat unknown part of the petals. The activities of such holder, is to move the sliding roof above the level of the matter, the ball bearing hinge rotation function using the full range of seismic ball joint mount elastomer seals to complete, while the fixed bearing, then in the middle upper steel plate embedded directly interact with the small plates excel are replaced only by deformation of the elastomer seal into the rotation function. Ball bearing hinge rubber sheet at the end of the top surface of the basin insert compression rings, wooden thing is to organize the elastomer is extruded from the space under the bottom of the pot to avoid intermediate steel week. The late 1950s began to develop abroad and apply ball bearing hinge, ball bearing hinge successfully developed in 1959 in Germany, and used on the highway bridge, a long time by the operator, and achieved good results , after the world have had specialized manufacturers pot bearings, and bearing design tonnage also increasing, the standard design in Japan in 1976, there 0.5-5mn pot bearings, ball bearing hinge of the Ministry of Railways Since 1975, the ball bearing hinge of the performance of a comprehensive study of the hinge bearing manufacturers, and the design is complete the Red River railway cable-stayed bridge with a ball bearing hinge, and with the 1990 completion of the industry standard "road bridge rubber bearing basin "(JT 3141-90) formulation, were developed in 1999 to form a new industry standard," highway bridge rubber bearings "carrying capacity of the original standard bearing 1000-2000kn, increased to 1000KN, expand the use of ball bearing hinges Currently, ball bearing hinges shall be subject to a wide range of applications on our roads and bridges, and has become one of the main bearing formation of roads and bridges, the new industry standard is being revised in. Ball bearing hinges are applied using the structure with isolation function in the seat at the ball joint at the hinge bearing supports, generally adopt LRB or rubber bearings, namely isolation and damping rubber integral damping support. Ball bearing joints such as the use of shock absorbing structure can make the bridge deformation properties and energy absorption increased simultaneously. Can also contribute to multi-span continuous and seamless development. Each ball bearing hinge parts should be kept intact, clean, at least once every six months, remove oil bearing around, garbage, prevent water, snow bidirectional ring bearing hinges, bearings ensure normal work. Rolling bearing rolling surfaces should be regularly painted oil, oiled before, ball bearing hinges should be rolling surface clean. Ball bearing hinge to be rust corrosion. In addition to the hinge axis and the rolling surface, the rest should be made part of the anti-rust paint brush, ball bearing hinge timely tighten bolts steel bearing combination ministries, the support plate smooth and firm.
