Rubber bearing basin is the use of the support plate to achieve vertical force supporting function, horizontal movement and rotation function of a class of surface contact spring retainer bearing habit seismic bearing, depending on the branch of the support plate into the sliding plate and elastomer composition drink bearing plate bearing surface plane and the supporting plate bearing a combination of two categories. Rubber bearing basin in contact with the line combination of support bearing plate bearing a combination of drinking and surface plane supporting two types of seismic type plate bearing steel ball bearings, rubber bearing basin to its large bearing area, and because the seat height is generally low, so as a load bearing structure is more stable and reliable rubber bearing basin is the oldest bridge bearings and also the simplest form of a seat, which consists of flat steel plates, steel contact surface in order to reduce friction longitudinal sliding side hinder, pot rubber bearing steel contact surface can be planed on the planer and lubricant coated with ink. However, fouling and corrosion often fail to use these bearings froze, sandwiched between thin stereotype plate and although helpful, but stereotype often squeezed out, if we remove the rubber bearing basin dirt, dust is embedded ink stone tablet bronze self-lubricating compound can be a good job, a very limited amount of displacement of the rubber bearing basin, and support end can not be freely converted amount. The maximum amount of vertical movement pot rubber bearing calculations, the maximum amount of movement for vertical steel beams bearing computing activities, according to inter-conversion are not calculated or load, dead load shall not calculate the basic allowable stress of steel beams span, the temperature coefficient of linear expansion of steel, calculate the temperature difference, the modulus of elasticity of steel, steel truss chord section weakening factor spring bearing manufacturer, can be approximated to 0.8, the normal displacement of the rubber bearing basin, the basin rubber support normal displacement amount of the seat according to the following. Roller normal displacement, a positive sign that stretch beyond the span, rubber bearing basin expansion coefficient of the main beam, the beam span calculation, component temperature measurement of bearings, bearing plate design, bearing and roller center line when temperature. The annual average of the highest and lowest temperatures. Longitudinal displacement pot rubber bearing member ends due to live load generated by the rollers appear if allowed crawling, skew or pan tilt axis, should be corrected bearing position. In order to avoid the rolling surface is blocked, rubber bearing basin can be mounted on the dust cover. Steel bearing sizing and checking details on the rubber bearing basin swing, hundreds of top plane size depends on the amount of support and pressure point construction area, the top surface of the plane should be wider than the transverse width of the beam end nodes 15mm base plate in order to be placed on board lectures swing tank top.
