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) 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) 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 , bearing surface contact with the supporting structure of the finished flat or curved vertical force of the anti-drawing steel ball bearing manufacturers of professional, when line contact bearings with a cylindrical surface of the support structure of the plane and the vertical force, the use of special red steel ball bearing type manufacture of bearings, according to the classification of its structure and composition can be summarized seat as a member. The level and intensity of the earthquake, the level of earthquake magnitude earthquake is represented by the level of seismic rubber bearing as 6 earthquake, 7.6 earthquake, 7.8 earthquake, 8.9 earthquake, etc., ball bearing type according to the level of earthquake The size of the release of energy, the energy released can be calculated by detecting the energy released by an earthquake more than the anti-drawing steel ball bearings, grade-level seismic rubber bearing the greater the current human earthquakes recorded the highest magnitude of 8.9, the energy released by the ball bearing is equivalent to an amount of 18 million T explosive hydrogen bomb, or the equivalent of a 40-year 100kw power plant generating capacity. May 12, 2008 14:28 GMT Wenchuan earthquake of 8 earthquake finished steel ball bearing anti-pullout factory outlets, the energy released is roughly equivalent to the amount of 900,000 T explosive hydrogen bomb, or 100kw power generation plant for two years. Formula to measure the magnitude and intensity of seismic scale indicators, measuring and calculating the level of ball bearings earthquake seismologists put forward by the United States, so that in the earthquake-level style often say how many earthquake Richter finished steel ball bearing anti-pullout Price, ball bearings, said magnitude earthquake releases energy in size. The maximum amplitude of the discipline to the epicenter, more than five earthquakes can cause varying degrees of damage, called the devastating earthquake. Finished steel ball bearing anti-pullout professional manufacturer of steel ball bearings _ _ anti-pullout a win-win business cooperation provided by the Engineering Rubber Co., Ltd.
