Lateral slide ball bearing steel PTFE sliding surface should set a reliable dustproof structure, in order to avoid contamination of the sliding surface Teflon outer bearing dust cover should be separate. Steel ball bearings and sliding beam and pier connected with sleeve bolt bearing steel universal quality standards, then you can easily replace the bearings when needed. Sturdy steel ball bearing slide exposed surfaces should be reliable paint protection, according to the sixth set of railway protection system for steel beams. Sliding steel ball bearings in the machining and assembly process should pay particular attention to what requirements: bearing steel pots and pots stuffed price accuracy and tolerances; one-way bearing activities tolerance fit between the guide groove; PTFE plate is consistent with the main surface of the reservoir displacement grease groove dimensions, arrangement, assembly direction, the tank is painted with grease 5201; seat height deviation after assembly meets design requirements. Supports for simply supported box girder preload 50KN should assemble in order to overcome the nonlinear load bearing part of the initial stages of deformation curve, four bearing box girder ensure uniform force. Steel ball bearing slide design, selection and use of different materials in different programs have a greater impact on the project cost, as the basis of the type of selection, to determine the depth and bay, the height and the number of layers to determine the structural form selection so there is a technical and economic analysis of the problem. Below the main structural parts illustrate: Basic: location of the project cost and geological conditions are closely related infrastructure, its duration is about 25% -30% throughout the building bearing steel truss main project promotion, cost accounting 10% -20% of the total cost, the importance of infrastructure projects is obvious. Therefore, the design should pay attention to the report of the tests, geological survey work, a reasonable choice of foundation type, control-based cross-sectional size and depth. This whole project cost of residential building control played a positive role. [Slide] ball bearing ball bearing displacement, by sliding on the bearing plate and the plane between PTFE slide to achieve. By the addition of the bearing plate guide grooves or guide ring bearing one way to restrain or displacement, can be made one-way bearing ball bearing and fixed bearing activities. Ball bearing plate by sliding the ball between the spherical PTFE slide bearings to meet the needs of the corner. [Slide ball bearing] reliable power transmission characteristics of ball bearing, rotating flexible steel supports, both with large pot rubber bearing load capacity, displacement volume and other characteristics, but also better able to adapt to the stand Large corner needs. Compared with pot bearings have the following characteristics: 1.4.1, spherical ball bearings through force transmission, does not appear necking force acting on the concrete reaction force more evenly; 1.4.2, ball bearing through sliding spherical PTFE slide bearings to achieve the rotation process, so the rotation torque is small, and the rotational torque only spherical radius of curvature and PTFE friction coefficient, not to the size of the bearing angle. Therefore particularly suitable for large rotation requirements, design 0.06rad corner up above; 1.4.3, each bearing identical performance to the rotation bearing steel manufacturers selling finished products for a wide bridge, curved bridge, ramp bridges, ramps Bridge and long-span bridges; 1.4.4, ball bearing rubber pressure without affecting the aging of rubber bearing rotation performance does not exist, especially for low-temperature region.
