Unidirectional activity self-lubricating ball joint bearing, self-lubricating ball bearing hinges, 13833855982 provided by the Engineering Rubber Co., Ltd. Hengshui HaoTong. 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. Ball bearing hinge situation contact force design value, on top or intermediate steel surface contact strength design value, the material partial coefficient recommended value, the value of the cylinder inner basin ring contact surface curvature radius of self-lubricating ball bearing hinge design elastic modulus, rotation geometric conditions required for the role of the basic combination bidirectional self-lubricating ball joint bearing activities, shall meet the following requirements, on the roof or intermediate steel plate with rubber elastic precipitation should be closed edge of the contact surface is formed along the entire perimeter of the ring at the end of basin cylindrical groove ball bearing hinge edge of the ring is neither from the basin, the top wall and the bottom bowl ring should not contact any metal component, subject to the following conditions in order to meet the above conditions, the ball bearing basin bottom hinge ring effective highly unidirectional activity self-lubricating ball bearing hinges, rubber sheet elastic material thickness, on the roof or in the middle of the plate and bowl ring contact height, the height of the roof or intermediate plate and bowl ring contact surfaces, maximum design angle. Ball bearing hinge ring diameter inner bottom basin, corner plates on the top surface of the roof or intermediate diameter, the surplus amount, the elastic modulus of the material design, the design value of horizontal force, surface contact area radius, variable effects produced. Steel plate stress ball bearing hinge design or design reaction force bearing capacity, steel floor area, the steel plate side length, allowable stress of steel plate material, steel plate material strength standard value, safety factors recommendations. Ball bearing hinges are developed on the basis on the basis of the pot bearing initiated on a ball joint mount, back in the 1970s, it developed into a foreign spherical seat, in 1988 China has also started to develop a spherical support seat and started for engineering practice, complete the national standard setting work in 2000, the spherical bearing not only involve adapt the scope of the corner and carrying capacity than ball joints are bearing large, so, enter the 1990s, spherical bearings China's large-span bridges in the project has been more widely used, and completed the revision of the national standard in 2008, while the completion of the core standard package involves the design drawings. General construction spherical bearing, ball bearing hinge by the bearing plate, spherical steel liner plate, the ball bearing slide hinge plane Teflon skateboards, skateboard spherical PTFE, seals and dust cover, etc. parts do, whose main components constructed spherical seat role and requirements. Ball bearing hinge plate can also be called a bottom basin, usually made of steel castings bidirectional self-lubricating sliding ball joint bearing, bearing also useful for small tonnage situation thick steel processed, mainly from the lower bearing plate fixed spherical tetrafluoroethylene the role of board and support forces dispersed passed to the supporting piers or abutments. Ball bearing hinge rotates by sliding spherical steel liner plate between the spherical PTFE plate to achieve, but usually spherical steel liner plate steel castings finishing, ball bearings and spherical hinge processing completed Now there are cases using coated stainless steel surfaces. If after using steel processing, machining precision sphere will refer directly affect the function of bearing rotation, which points to attract attention.
