Hengshui Hao Tong Engineering Rubber Co., Ltd. is engaged in the production and sales slide ball bearing hinge 20 years of Chinese lines of business. I. Introduction slide ball bearing slide hinge ball bearing hinge basic structure: is a sphere, PTFE slide, box, closures, the spherical shell, base, sealing plate, stainless steel plate and other components. Sliding ball bearing hinge is a structural improvement and optimization of ordinary steel ball bearing. The series not only has ordinary ball bearing steel bearing bearing capacity, rotating flexible, reliable power transmission, angle and other characteristics, but also can reduce the vertical and horizontal tensile shear force due to the earthquake, the lateral sway forces, such as wind generation has a transverse Cut and so on, but also to ensure that does not fall when the horizontal seismic beam, with good damping properties. This series bearing the strict implementation of People's Republic of China National Standard GB / T17955-2009 "Bridges ball bearing", is a new grid support. Second, slide ball bearing hinge works: from the base slip displacement is implemented in the box; corner is a sphere with a relative rotation of the spherical shell and the base to achieve; anti vertical tension is a sphere, the shell, chassis and cabinet realized; horizontal force is composed of cabinet, base and sphere realized; fixed hinge bracket without displacement boxes. Third, the sliding ball bearing hinge classification: According to the project structure and bearing performance, can be divided into three types: unidirectional sliding hinge bearing (DX) bidirectional slide hinge support (SX) fixed hinge bracket (GD) Fourth, slide ball bearing hinge design parameters ◆ Supports vertical bearing capacity into 300KN ~ 10000KN fourteen levels; ◆ bearing design angle is 0.08rad; ◆ Supports anti vertical Rally for vertical bearing capacity of 20 % or 30%; ◆ Supports anti horizontal force of 20% vertical bearing capacity; ◆ radial displacement of the bearing ± 20mm- ± 50mm, ring to the displacement of ± 60mm- ± 100mm; (above technical requirements are Can be designed and manufactured according to customer requirements) five, slide ball bearing hinge selection should pay attention to matters: ◆ selection of bearings should pay attention to the size, the size of the vertical tension, horizontal force bearing capacity of the size, and note the amount of displacement and corner, should also pay attention to the level of damping bearing elastic stiffness. ◆ choice should stand note bearing types, namely two-way activity type, one-way activity, stationary. ◆ constrained damping bearing gave direction to the displacement and stiffness, damping to the needs of engineering.
