Detailed Product Description: | Damping hinge steel ball bearings, bi-elastic steel hinge bearing, ball bearing hinges, steel hinges seismic ball bearing, bearing universal tensile steel ball bearings, bearing walls, finished fixed hinge bearing, Finished hinge bracket a, damping hinge steel ball bearing Product Overview WQGZ-II series is based on the People's Republic of China bearing seismic damping transportation industry standard "highway bridge rubber bearing basin" (JT391-2009) and Highway Engineering seismic design code (JT004-89), in WQGZ basis (I type) Series seismic damping bearing on, the detailed statics, dynamics analysis developed from a new seismic damping steel bearing. WQGZ-II series of seismic damping bearings compared WQGZ (I type) seismic damping bearing structure is more reasonable, more reliable performance and longer service life. WQGZ-II series includes a fixed bearing seismic damping bearings, one-way bearing activities, bearing three types of two-way activity, bearing specification is divided into 22 levels, bearing vertical design capacity, design corner, friction coefficient according to the design requirements of the relevant standards. Its level of capacity, the overall strength of the vertical uplift and bearing than ordinary bearings have greatly improved. The series bearing elastic damping element, with a clear mechanism of clear structural parameters stability, excellent damping performance characteristics. The principle is the level of damping force to a certain extent, the damping spring is elastically deformed to achieve the start buffer. When the corner structure, the ball is rotated to produce the core, the release of the upper structure generated by the torque. When the earthquake, rigid and flexible seismic measures simultaneously the role of damping measures to resist the huge earthquake input energy. In the big earthquake fluctuations, both to ensure the bridge, under construction between reasonable relative displacement amplification factor is reduced seismic forces, and also allows the structure to maintain unity. The bearings can withstand 8-11 degrees earthquake, especially for highly seismic area of ??engineering structures epicentral earthquake zones have good seismic damping effect. This series of bearings for large-span spatial structure and large-span bridges, especially for wide bridge, curved bridge, bridge of, especially for engineering structures in highly seismic zone. The series has been staged in the Ministry of Construction Research Institute of Metallurgical Engineering Structures Laboratory, Shijiazhuang Railway Institute engineering structures and Testing Center, Shanghai Tongji Construction Quality Inspection Station, Guangzhou University Earthquake Engineering Research Center qualified. Second, the damping hinge steel ball bearing design and manufacturing principles shape evenly structured, both in the structure of the plane or facade arrangement, have sought to make geometry, stiffness regular uniform ductility improves the strength and ductility of the structure and components. Multi-channel vibration defense. Fragility and instability prevent damage. Prevent material aging. High quality manufacturing and installation. Third, the damping hinge steel ball bearings Stainless steel plate, PTFE slide, rubber seals and other standard provisions according JT391-1999 which damping spring by QCn29035-91 automotive leaf spring technology conditional execution. Cast by GB / T11352-1989, GB / T14408-1993 standards. Fourth, the advantage of damping steel ball bearing hinge bracket using spherical contact, a large contact area, the pressure is low, mass force uniform, small, small amount of steel. Be universal bearing, can withstand the pressure, shear forces and pull in any direction. Be universal rotation to release the bending moment in any direction. Supports use of damping spring, damping can meet the need of high intensity area of ??engineering structures. Force bearing parts are made of steel, in 200 years there is no problem of aging. PTEF bearing products used, the friction coefficient is small, aging resistance, low temperature up to -150 ℃, ensure the universal application of the flexibility of bearing rotation and cold regions in the north. Reaction force concentrated, clear, no change over the corner. Supports the role of the lower structure (columns, piers) by force. Supports dynamic and static stiffness, ensuring the smooth running of the vehicle. Seat height is low, enabling the design of the bridge structure.
