Ball bearings, will vary with the form of engineering structures continues to expand, its use will continue to expand the scope and with the progress of science and technology, new materials appear, improvement and development process, the spherical bearing in the form of not limited to the rubber material of the trip, while the use of other forms of elastomers, and construction will continue to emerge and develop, so consider using the formula, you should pay attention to new materials, new techniques for structural and latest products. Bearing ball bearing or main castings made from steel processing, past rolling KQGZ seismic spherical steel bearing -ZX, is generally used as a bridge abutment use, ball bearing type test steel parts, swing and to adapt the displacement of the sliding bridge, and rotated. Rubber bearing structure according to its use and there are multiple types of bearing capacity is characterized by his ability, can use a variety of bridge displacement and rotation needs, and on the great rebates and a large displacement of the support beams and has a very negative rebates good use, before the 1960s, mostly small and medium-span bridges use steel bearings, bearing large tonnage highway bridge now use pot, rubber bearing more, but people generally use steel railway bridge abutment, commonly The steel bearings are steel bearings and special bearings and so on. Taking into account the effect of vibration often exceed the design strength of the earthquake, the early syndrome ball bearing bolts earthquake damage KQGZ spherical steel bearing -DX, along the bridge and transverse to the fiber means the destruction of the earthquake to prevent the pulling force Separation of metal components and the bearing damage, with the shear deformation of rubber bearing plate and so on. Therefore, when the ball bearing design, the following aspects should be noted. (1) When a horizontal force to overcome the earthquake and pulling force of the earthquake on the use of steel castings do not ask, you should use the high toughness of the material. (2) Spherical bearing member are inverted response to cell processing in order to prevent stress concentration. (3) bearing the same support line should take appropriate measures to prevent all break (4) the use of a higher seat height of occasions to deal with limited means to prevent the high elevation of used together. (5) deal with rubber bearing horizontal movement and rotation of the bearing surface, take abrasion, corrosion and dust handling. (6) ball bearings premises in materials used must meet the performance requirements and manufacturing a wide ball bearings ensure multi-directional KQGZ seismic spherical steel bearing, according to the vertical force of the support structure into surface contact bearing, line contact Drink ball bearings and other bearings, bearing surface contact with flat or curved support when the vertical force structure, line contact with the plane and cylindrical bearing surface of the support structure of the vertical force, the use of special red when the ball bearing steel manufacturing bearing, according to the classification of its structure and composition can be summarized as holder belongs.
