Truss unidirectional sliding ball joint bearings, ball joints unidirectional sliding bearings, specialized factory Hengshui Hengshui Hao Hao Tong Tong provided by the Engineering Rubber Co., Ltd. Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) Hebei Hengshui, a leader in site construction materials, over the years, the company is implementing scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Hao-engineered rubber leadership with the staff warmly welcome all inquiries negotiations to create Hao-engineered rubber a better future. Plane and spherical PTFE sheet PTFE plate bearing horizontal displacement by plane PTFE plate and slide on the ball bearing hinge plate between stainless steel plates to meet the needs of its working principle is consistent with the pot bearings, and rotation by spherical and spherical PTFE sheet steel liner plate sliding completed accommodate the larger corner. Ball bearing hinge plane and spherical PTFE sheet PTFE plate as a major bearing sliding parts, therefore, on the surface of PTFE sheet should be used tanks professional molded and placed in isolation lubricating grease unidirectional slip the ball joint bearing, PTFE slide to reduce sliding friction and wear. Ball bearing hinge plate is generally made of ordinary steel or cast steel, ball bearing hinge plate in contact with the PTFE plate side. After welding a steel bar immortal and flatness requirements PTFE plate diameter of not more than 0.03, the coefficient of friction bearings to ensure no more than 0.03. By setting a different steering ball joint bearing structure on the board can be done constraints unidirectional or more of the displacement can be processed into a number of spherical bearings, spherical bearings drink unidirectional fixed spherical bearing, their general structure. The main features of the spherical bearing spherical ball bearing hinge drinking pot bearing surface contact when the force of the seat by form type, single they type a difference, mainly in what areas, first drink spherical ball joint bearing basin branch rotation of the seat surface forces are passed through, so the bearing surface of the bearing under stress is relatively uniform, spherical PTFE slide when the slide bearing spherical ball-shaped crown by steel liner plate and contacts to meet the bridge abutment Requirements truss unidirectional sliding ball joint bearing, flexible rotation, and fully release the seismic moment unidirectional sliding ball joint mount is ideal hinge. Once the ball joint bearing part of the functions of local damage or imperfect situation, the agent will have a greater impact other functions. Therefore, the use of the whole structure type, need to fully take into account the combination of features and its strength can be sure that the various effects (or load) state functional requirements. Loads structural separation Functional separation method, the ball bearing hinge mainly for vertical and horizontal support functions supporting functions, each essential functional separation. Ball bearing hinges are usually based on the state of the earthquake and wind load rating unidirectional sliding ball joint bearing, ball bearing hinge can have a variety of functional separation method to separate the entire architecture bridge seismic properties assumed in the design There should be no significant difference; at the same time, during an earthquake, it may appear on the deformation of the lower structure set up foundations, live in the top of the narrow width of the lower structure, and constitutes only one pivot bearing and bearing transverse direction after injury and downs Beam dangerous bridge, in principle, the use of B class seat
