In the design, the general requirements to use ball bearing at least 30 years or more actual foreign demanding, ball bearings, such as the use of substandard products, not in three to five years, ten years, we will be problems, when in the long run, will reduce the life of rubber bearings, and the emergence of the early damage damping ball bearing steel bearings, spherical bearings causing economic losses, which is currently the main existing ball bearing One of the problems, the Hope Project using the unit, not only as the main basis cheap to buy support. Installation and maintenance, the ball bearing installation and maintenance, but also affect the laminated rubber bearings use of effects and the key to life lxqz steel ball bearings, ball bearings so the newly revised industry standard, an increase of some of this requirements. If you install unreasonable qz series steel ball bearings, not the construction process, the construction process mishandled or branched seat cushion stone and beam bottom center of the plate receiving seat centerline do not coincide and so on. After the ball bearing girder installation is complete, you may have a bearing bias goods appeared not meet the requirements of the initial shear deformation, which are a direct impact on the life of rubber bearings use of effects and, therefore, the construction must be ensure close contact with the two bearings, ball bearings and piers between, so bearing force uniform, does not allow partial pressure and the Void phenomenon. Ball bearings sometimes encounter after construction is completed, the construction of temporary taken to prevent the displacement of steel ball bearings fixed setting, no timely removal, in addition, the construction process because the laminated rubber bearing considerable amount of installation work. Ball bearings in the upper part of the structure of the external force can be transferred from the load bearing structure spread substructure. Also the force transfer process may be performed in a variety of delivery. To accurately grasp it, you must validate the performance of rubber bearings. Rubber bearing multi-point fixation seismic horizontal forces dispersed structure set ball bearing structures in several piers providers. When the earthquake, the inertial force of the upper structure were high seismic performance by the pier but the machining accuracy of the contact surface is difficult to control, the situation is the same with the line contact bearings lot of damage, so the calculation to determine the friction coefficient must be noted that this case . Is the use of shear deformation of rubber bearing horizontal force will be passed to the type of support substructure. Thus, the ball bearing in view of the horizontal forces and the entire rigidity of the upper and lower rubber bearing portion of the structure is calculated. Using damping structures such as bridges deformation can make to improve performance and energy absorption simultaneously. Can also contribute to multi-span continuous and seamless development. qz series of steel ball bearings, industry-standard [Hengshui HaoTong], steel ball bearings provided by the Engineering Rubber Co., Ltd.
