Description :

　　KLQZ fixed spherical bearing manufacturer tension compression spherical steel bearing shock absorption elastic spherical steel bearing finished product

　　The working principle of KLQZ fixed spherical support is achieved by the relative rotation of the ball core, upper seat plate, and base; Displacement is achieved by the sliding of the base in the box; The resistance to vertical tension is achieved by the upper seat plate, base, and box body; The horizontal force is achieved by the box, base, and upper seat plate. The structure of the bi-directional sliding ball joint support consists of an upper support plate (including stainless steel plate), a crown liner plate, a lower support plate, a flat polytetrafluoroethylene plate, a double-sided polytetrafluoroethylene plate, and a dust-proof structure. The bi-directional sliding ball joint support can be unpacked before installation.

　　Check the packing list of tension and compression spherical steel bearings, including accessory list, product certificate, etc., and carefully read the installation instructions of the bearings. Check whether the assembly position of the support is correct and whether the temporary connection is loose, but do not loosen the temporary connection of the support arbitrarily. The various types of ball joint supports for the truss are composed of an upper seat plate, a lower seat plate, a convex middle steel plate, and two different shaped polytetrafluoroethylene plates. The middle of the lower seat plate is a concave spherical surface, corresponding to the convex middle plate. There is an arc-shaped PTFE plate lining between the two, which slides with the spherical surface to meet the rotation of the beam end. The stainless steel plate on the upper seat plate and another PTFE plate on the middle steel plate form a second sliding surface, completing the expansion and contraction displacement of the upper and lower structural bodies due to temperature differences and other factors. The displacement of the ball joint support is achieved by the sliding between the upper support plate and the planar PTFE plate.

　　The shock-absorbing elastic spherical steel support sliding support realizes the rotation process of the support through the sliding of the spherical polytetrafluoroethylene plate. The rotational torque is small, and the rotational torque is only related to the radius of the support sphere and the friction coefficient of the polytetrafluoroethylene plate, and is independent of the size of the support angle. Therefore, it is particularly suitable for the requirement of large turning angles, with a design turning angle of 0.05 rad or more. The bearing has consistent rotational performance in all directions and is suitable for steel structures such as trusses, corridors, overpasses, membrane structures, as well as wide bridges, curved bridges, and other bridge constructions; The bearing does not require rubber pressure and does not have the influence of rubber aging on the rotational performance of the bearing, making it particularly suitable for low-temperature areas.
