After the ball bearing hinge installation is complete, the general response to the vertical stand under its load compression deformation under load bearing basin for-equipped to understand the performance of the radial deformation and sitting coefficient awakened detection module, the overall performance of the test stand Bloody tests should be carried out in specialized institutions. Currently, large plants are equipped with conventional testing equipment, so it can be specified at the factory when conditions permit. Xuan should hinge on the ball bearing mechanical properties of the principle of corpses ball joint bearing, such as test equipment can not meet a single large bearing when tested, in consultation with the users to choose a small ball bearing hinges for testing. For the test sample, the test content, test methods, test data collation and requirements, test structure determination and detection rules and other industry standards are clearly defined. Which should work with oblique linear Anju industry standard regulations and requirements. Ball bearing structure design hinge mainly on the basic size ball bearing hinge to determine the main components, namely, fixed ball joints steel PTFE slide bearings, rubber sheets, steel pots ring, steel baseplate and adapt corner bearing checking and other necessary and shall meet the provisions of the relevant regulations and standards. The basic rules of design principles ball bearing hinge bearing design, China's current bridge design specifications, ball bearing hinge design not requested activities hinge steel ball bearings, generally allowable stress design is still in use, according to foreign designs and practical experience, ball bearing hinge design generally follow the following principles. A support line for the same center of rotation of the ball joint bearing steel sliding ball joint bearing, in the hope that the center of rotation on the bearing in a straight line. Ball bearing hinge structure, must pay attention to the structure of the rotation produces poor unreasonable force calculation would produce outside. Providing two or more continuous fixed support, in addition to the horizontal forces due to temperature changes, the need to consider the horizontal force generated by the rotation of the beam. The seat should be chosen because of the longitudinal and transverse displacement and angle of beam produced by the deformation and so unfettered as possible. For concrete bridge according to its characteristics of elasticity of the seismic forces dispersed, the ball bearing hinges absorb a certain effect, so far, for these forms of bridges, unless there are special considerations, ball bearing hinges are generally used this Supports curved forms of the moving direction of the bridge because of its inconsistency with the direction of rotation, for this bridge, it is generally desirable to form a full range of moving and rotating bearings, ball joints which is the basic requirement of 20 years experience in the production of steel bearing manufacturers _ sliding ball bearing steel hinge hinge steel ball bearings _ provided by Hao-engineering rubber.
