Therefore, rubber bearing basin generally used for less than the span of the bridge, commonly used in highway bridge to span 12-15m of rubber bearing basin, available to the span of about 8m on the railway bridge, and now, a large flat seat section should be replaced by laminated rubber bearings. Rubber bearing basin, also known as roller bearings, roller bearings are long-span steel bridge and concrete bridge abutment common form. Rubber bearing basin is usually tied by a number of small diameter rollers, groups linked together by rotating rollers to accommodate the displacement of the beam body needs. Depending on the number of rollers bearing on the size of the reaction force, according to the size of the line of contact stress. Rubber bearing basin to determine the diameter of the individual rollers need. At the top of a set of rollers additional qkpz pot rubber bearing rubber bearing basin, in order to ensure free rotation of the beam end. Roller bearings under the floor must have a certain rigidity, a packet of documents bearing license plate, usually rollers made of high-strength forged steel to reduce its diameter and height of the entire basin rubber bearings for roller shaft support structure. In order to save steel and reduce the length of rubber bearing basin. Pot rubber bearing manufacturers, on both sides of the roller can be trimmed away, be sure to pay attention to a single design to ensure that the rollers can still be cut to adjust the desired amount of displacement without subversion, in order to ensure that the relative position between two rollers, basin rubber bearings usually set in rollers rod end of the beam at the center, so that the rotation axis parallel to the rollers. Large contact damage at this time, there will be friction coefficient value greater than the design requirements circumstances, it is generally desirable to avoid the use of a movable bearing, rubber bearing basin-way pot rubber bearing, generally by providers, basin rubber bearings and pin bearings, rubber bearing basin of the top surface of a great arc of curvature and the underside is appropriate bearing plane, and between them in the circular pin hole design to withstand the longitudinal horizontal force. If used as a rubber bearing basin should pin hole as a growing hole, so that rubber bearing basin can have a small amount of slippage. Radius pot rubber bearing checking should be given face. Rubber bearing basin generally used on 16m below the bridge span, curved bearing often occurs in the course of rotation is not flexible or being cut phenomenon, the main reason is due to the curved contact surface contact stress is too large to be pressed Ping is difficult bearing rotation, and because the pot rubber bearing bolt and welded steel beam at the end, the emergence of the lower shear bolt before, so now basically curved seat has been replaced by rubber bearing basin reasons.
