When considering the role of the earthquake to often exceed the design of vibration force, will permit early ball bearing bolts destruction, damage to the bridge and along the transverse direction of the fiber device to prevent the pulling force of the earthquake and the upper bearing metal structures separation of destruction, with the rubber bearing plate shear deformation. Therefore, when the ball bearing design, the following aspects should be noted. (1) In order to overcome the earthquake horizontal force and pulling force of the earthquake on the do not ask when steel castings using vibration ball bearing steel, high toughness material should be used. (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) the ball-type bearing material used herein must meet the performance requirements and the types of manufacturing ball bearings to ensure, in accordance with the vertical force of the seat support structure is divided into surface contact, line contact ball bearings and other bearings drink , while bearing surface contact with the supporting structure flat or curved vertical force line contact bearings with flat and cylindrical surface of the support structure of the vertical force, the use of special red steel manufacture anti-vibration ball bearings finished steel ball bearings support when Block Factory outlets, according to the classification of its structure and composition can be summarized as holder belongs. A test with cement mortar mix, adjust and determine, should be used for the test with the actual use of materials engineering, mortar test should be used with mechanical stirring, mixing time shall not be less than 120s finished steel ball bearing manufacturers offer vibration, ball bearing press calculation or look-up table of the mix stirred, should be measured degree of consistency and its Mixture stratification, when the finished product does not meet the requirements of the anti-vibration ball bearing steel prices should adjust the amount of material, knowing that meet the requirements so far, and then OK Mix the mortar benchmark test timing and test should be used with at least three different mixing ratio, the benchmark ball bearing one of the preceding paragraph, the mixing ratio, ball bearing other cement mixing ratio shall be Mix the benchmark 10% increase or decrease, respectively, to ensure the consistency of the stratification of the eligibility conditions, water can be adjusted accordingly. For three different mixing ratio after adjustment, should be required to existing relevant standards molding, strength testing of mortar, ball bearings and selected in line with the requirements of the test with strength and with the minimum amount of cement as a manhole fit ratio.
