Room for PTFE plate material used ball bearing hinge friction coefficient test itself, as well as the materials used in the three-tier composite board fastness and compression tests have been done in the material description is not repeated here. When the ball flat and curved hinge bearing combination bearing plate bearing, ball bearing slide when the plane part of the support plate to complete the horizontal movement to achieve flat and curved parts of the rotation function of ball bearing hinges, if the holder of such made of spherical curved section becomes full-rotation type of bearing hinge bearings, spherical bearings in our call; and as it becomes a one-way type cylindrical bearings. Usually referred to as swing column supports, such smaller steel ball bearing slide hinge pin hinge if its radius of curvature of a surface made of, you can get a large amount of rotation, this bearing function and horizontal movement Turn the function depends on the size of the support plate and the friction coefficient of the sliding contact material. So, the ball bearing hinge dust and protective measures must be taken to prevent increased wear and friction coefficient. Further, if the high-strength brass supporting plate, due to machining accuracy of the contact surface is difficult to control and the year of aging, friction characteristics vary thereby causing the moving machine rotation problem exists impaired function, so in addition to attention in use, but in is also necessary to limit the large amount of rotation. Ball bearing hinges are applied using the structure with isolation function in the seat at the ball joints at the supports, the general can LRB or rubber bearings, namely isolation and damping rubber shock integral support seat. Ball bearing joints such as the use of shock absorbing structure can make the bridge deformation properties and energy absorption increased simultaneously. Can also contribute to multi-span continuous and seamless development. Each ball bearing hinge parts should be kept intact, clean, at least once every six months, remove oil bearing does not move around the hinged bearing manufacturers, waste, prevent water, snow, to ensure normal work stand. Rolling bearing rolling surfaces should be regularly painted oil, oiled before, ball bearing hinges should be rolling surface clean. Ball bearing hinge to be rust corrosion. In addition to the hinge axis and the rolling surface of the fixed hinge bearing hinge support activities, and the rest should be made part of the anti-rust paint brush, ball bearing hinge timely tighten bolts steel bearing combination ministries, the support plate smooth and firm.
