Ball bearings are usually divided into non-stiffening stiffening bearing two kinds of drink holder. Only one non-stiffening rubber bearing, at the level of force, although the level of rubber bearings to meet the needs of shear deformation, but bearing in vertical loads tend to produce vertical deformation. At this point, the ball bearings due to constraints is relatively small, and because incompressibility bridge universal rubber ball rotation bearing, ball bearing deformation of universal rotation only lateral expansion of steel ball bearings, certainly in its surrounded by a larger larger convex rubber oil drum at the tensile deformation, resulting in stress aging. Such ball bearing on our roads and bridges is not recommended. In order to withstand large vertical loads can also meet the needs of horizontal displacement, the bridges are generally used stiffened laminated rubber bearings, ball bearings stiffening stiffening universal rotation damping material can be steel ball bearings, glass fiber , cotton, nylon cloth, single use of bridge steel stiffening material is not recommended to use other materials, stiffening plate rubber self-made under vertical loads, steel embedded rubber sheet rubber between the lateral expansion will limit the convex drum vertical deformation is reduced accordingly, thus greatly improving the vertical stiffness of rubber bearings. At this time, the ball bearing vertical deformation of the total deformation will be the sum of each thin rubber sheet. 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 universal rotation of spherical bearings, improvement and development process, the ball Supports form of rubber material are not limited to travel, and 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 processes for structural and latest products. Bearing ball bearing is mainly made of steel castings or steel processing, in the past, is generally used as a bridge abutment using a rolling ball bearing type test steel parts, swing and slide to accommodate the displacement and rotation of the bridge a. 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.
