Since the elastic ball bearing deformation and has good cushioning properties, so there is a certain seismic rubber bearing performance and better shock absorption cushioning effect against drawing pot bearings, but the design of the research on the rubber bearing started late, it can be said that is just the beginning, shear properties and stiffness errors especially for ball bearing brought by pulling state of durability, fatigue resistance, bonding of rubber bearings and steel durability, weather resistance rubber protective layer, etc. are subject to further study these issues in the future can be further done a lot of work. Currently, according to the type of classification, rubber bearings can be summarized as laminated rubber bearing, shock absorption and isolation bearings (LRB) and rubber bearings, chapter narrative form by rubber bearings respectively. Laminated rubber bearing is not a new product, and it is the child in the 1930s began to develop abroad, has been 70 years of history, we can say is a relatively mature product bearing, in foreign countries, rubber bearings Mr. E.GKimrnich rubber engineering authorities in different form factor, different rubber hardness of specimens thousands of times of stress - strain experiments, the first application of laminated rubber bearings on the outskirts of the French steel bridge seismic stations Sainfpenis spherical steel support Block, to the 1960s with cement mortar with a test, adjust and determine test should be used with materials engineering actually used mortar test should be used with mechanical stirring, mixing time shall not be less than 120s, ball bearing by calculation or ratio seismic type stirring pot bearings should be measured degree of consistency and its Mixture of stratification, when you can not meet the requirements, you should adjust the amount of material to know to meet the requirements so far, with a look-up table and then try to determine when the tie Mix the mortar benchmark, test should be used with at least three different mixing ratio, the ball bearing one of the preceding subparagraph benchmark mix, with ball bearings other than the cement mix should be the benchmark, respectively increased or decreased by 10%, to ensure the consistency of the eligibility conditions of stratification, water can be adjusted accordingly. For three different mixing ratio after adjustment, should be required to existing relevant standards of molding, strength testing mortar, ball bearings and selected in line with the requirements of the test with strength and with the minimum amount of cement with a manhole ratio. Reference with cement mortar cement mortar mix ratio. Seismic steel ball bearings, bearing Fuyang, Hao-brand factory direct bearing life of 50 years provided by Hengshui HaoTong Rubber Company.
