Between the rubber sheet is embedded in the rubber layer to prevent lateral expansion convex drum, while the ball-type bearing shear stiffness had little impact at the level of the role of the one-way sliding displacement force H spherical hinge bearings, rubber bearings produced the amount and the level of non-stiffening rubber bearing deformation roughly the same. Ball bearing similar bridges generally use several layers of thin rubber sheet and stiffener plate for stiffening rubber bearings, ball bearings, the finished product is between the layers of rubber sheet with adhesive coated by a thin steel in the mold pressing a vulcanized integral structural configuration. Displacement of the ball bearing and bearing only the net thickness of the rubber layer spherical hinge of fixed bearing, in addition, in order to prevent corrosion stiffening steel, ball bearings on, under and around the stiffening rubber bearings have a certain The thickness of the rubber protective layer. Transportation industry standard "roads and bridges laminated rubber bearings" (JT / T 4-2004) of provisions for ordinary plate and rectangular and circular rubber bearing laminated rubber bearing given the specific structural configuration shown. Ball bearings using high-quality carbon steel or steel into the Forbidden City molding, foundry damping hinge ball bearing, casting, heat treatment, machining and surface treatment of steel. Common are spherical bearings, cylindrical children u Oh, cylindrical bearings, roller bearings, flat bearing, ball bearing rolling bearings and other types of drinking pot bearings, rubber bearings carrying capacity is relatively large but its structure size is relatively large, the amount of steel consumption and more, because of its large spherical hinge bearing just spent force transmission sharply lower structure likely to cause damage, but also easy to rust ball bearings, high maintenance costs, repair hinges difficult. Mechanically when the ball bearing structure to achieve load transfer capability, the level of mobile features and functions of the rotation early enough, compared with a more vertical stiffness rubber bearings and rotating big strong absorptive capacity, and other prominent features, single due to bearing the different types, there will be a problem in the first virtuous horizontal displacement direction and the rotational direction, while, due to the ball bearing to bear the rotation bearing function and the function of the horizontal movement of 米昂 Once damage occurs, or the problem of corrosion and only pretending to be will fail problem requires attention. Therefore, you must wear a support surface using corrosion-resistant materials and attention dust repellant.
