Spherical Bearings Pot Bearings use of worry PTFE sheet rubber bearings

Spherical bearings using PTFE plate worry pot bearing rubber bearing QZ spherical rubber bearing on the bearing plate consists of lower bearing plate, spherical plate, Teflon slide (ie flat PTFE plate, spherical four fluorine plate) and rubber ring consisting of a rubber bearing products. It just pot bearing rubber sheet instead of the spherical PTFE plate; intermediate plate and the bottom basin is correspondingly changed sphere, reducing the coefficient of friction. Its displacement by the slide on a support plate and the plane between PTFE plate to achieve. Set the guide groove or guide on the carriage plate bearing unidirectional ring to restrain or displacement, it can be made one-way movable spherical bearing and fixed bearing. By sliding the ball between the plate and the spherical PTFE plate to meet the needs of the holder corner. Spherical bearings using PTFE plate worry pot bearing rubber bearing spherical bearing, it is a force transmission through the spherical, having not appear force necking the bridge bearing products, the use of this product in the concrete reaction force uniform, spherical PTFE plate through the sliding bearing to achieve rotation of the holder, in use, the rotation torque is small, and only the rotational torque of the spherical bearing and the radius of the friction coefficient of the PTFE plate concerned, has nothing to do with the bearing angle size. Therefore particularly suitable for large rotation requirements, design angle up 0.05rad more. Each bearing to rotate consistent performance, suitable for a wide bridge, curved bridge; seat without rubber under pressure, there is no impact on the aging of rubber bearing rotation performance, especially for low-temperature region. Categories ball bearing spherical ball bearing by power transmission, does not appear necking force acting on the concrete reaction force more evenly; spherical bearing spherical PTFE plate by sliding to achieve rotational bearing process, rotation torque is small, and only with the bearing rotating torque and friction coefficient of spherical radius PTFE plate, not to the size of the bearing angle. Therefore particularly suitable for large rotation requirements, design angle up 0.05rad more. Each bearing to rotate consistent performance, suitable for a wide bridge, curved bridge; seat without rubber under pressure, there is no impact on the aging of rubber bearing rotation performance, especially for low-temperature region. QZ spherical rubber bearing (firm to the carrying capacity) is divided into 16: 1000,1500,2000,2500,3000,4000,5000,6000,7000,8000,9000,10000,12500,15000,17500,20000kN, more than 20000kN alone design and processing. . QZ rubber bearing performance of a longitudinally movable bearing code-named ZX; b multidirectional bearing activities, code-named DX; c fixed bearing code-named GD; product temperature range: a normal type support: Suitable for -. 25 ℃ ~ + 60 ℃; b cold-type bearings: Suitable for -40 ℃ ~ + 40 ℃, code-named F. Ball bearing technical performance a. Bearing design angle into 0.01,0.015 and 0.02rad, b can be increased as needed. 1000-20000KN divided into 16 vertical bearing capacity of the horizontal bearing capacity of the bearing can withstand 10% c vertical friction coefficient: normal type μ≤0.03 cold type μ≤0.05 d bearing design displacement volume: along the bridge: ± 50, ± 100, ± 150mm transverse direction: ± 20mm design according to the amount of displacement project needs to be changed QZ spherical steel bearing at installation steps and methods:. 1, QZ spherical bearings at the factory, it has been the seat leveling and tighten the bolts to prevent the occurrence of the spherical bearing during installation rotation and overturning. We need to design the user preset angle and displacement, but the construction unit shall submit the preset angle and displacement of the requirements before ordering by manufacturers in the pre-adjusted during assembly. 2, can be installed in front of the box, and check the packing list, including parts lists, copies of inspection reports, certificates and rubber bearing product bearing installation conservation rules. After the construction unit of the box, one shall be arbitrarily rotated bolts, and one shall be arbitrarily dismantle support. 3, the mounting height should meet the design requirements, to ensure that the level and flat rubber bearing plane. Spherical bearing bearing surface height shall not exceed four corners 2MM. 4, the spherical seat of one year after the trial operation should be checked, remove debris and dust nearby seat and carefully remove dust stainless steel surface with a cotton thread. The company specializes in the production of two-component polysulfide sealant, rubber water stop, rubber seal, water swelling rubber seal, closed-cell polyethylene foam, inflatable mandrel, rubber bearings, expansion joints, two-component polyurethane sealants.
