Example Embodiment
[0021] The support steel plate and rubber layer can be processed in accordance with conventional methods. The vulcanization and fixing of the support can be performed in accordance with conventional production methods. The fixing during production can be fixed from one or both ends, and the lead core can be pressed in from one or both ends. .
[0022] The ring-shaped lead rubber bearing can be manufactured separately from the inner rubber bearing part and the outer rubber bearing part, and then assembled, and then pressed into the lead core; it can also be processed and produced as a whole and then pressed into the lead core.
[0023] The lead-free core ring-shaped middle-hole rubber bearing can be manufactured separately from the inner rubber bearing part and the outer rubber bearing part, and then assembled; it can also be processed and produced at the same time.

An improved rubber support comprises a rubber support body with a hole or a lead core variable, a rubber support body with multiple holes or lead cores, a large-dimension rubber support body, a rubber support body shaped like a variable steel plate, a rubber support body with a variable steel plate arranged on the surface and a rubber support body made of a variable steel plate. The shape and the height proportion of middle holes or the lead cores can be adjusted, and the side boundaries of longitudinal and radial profiles of the middle holes or the lead cores are broken-line-shaped or curve-shaped, for example, the side boundaries can be trapezoid, V-shaped, T-shaped, folded-line-shaped or curve-shaped or in a combined shape so as to meet the requirements for different shock insulation design. A plurality of holes can be arranged on the horizontal profile of the rubber support, and the position, the number, the size and the shape of the holes can be adjusted according to requirements. None or one or several lead cores can be arranged, the lead cores can be placed in part or all of the holes, the shape of the holes or the lead cores can be single or variable, the height of the holes or the lead cores is adjustable, and the height of the holes can be the same as or different from that of the lead cores. The rubber support can be a large-dimension (such as large-diameter) rubber support. The surface of a middle interlayer steel plate can be non-planar, and the surface of the steel plate can be uneven and rough.
Description
technical field [0001] The invention relates to a rubber bearing. It is an improved rubber bearing, including a rubber bearing with variable holes or variable lead cores, a porous or multi-lead rubber bearing, a large-size rubber bearing, a rubber bearing with a variable steel plate shape, a A rubber bearing that changes the surface of the steel plate and a rubber bearing that changes the material and characteristics of the steel plate. The size, shape, and number of lead cores can be adjusted according to the isolation effect, and the horizontal stiffness, initial stiffness, and hysteresis curve of the rubber bearing can be changed. It can be a large size (such as a large diameter) shock-absorbing rubber bearing to bear a large load. It can be conveniently used in seismic isolation structures, and can flexibly meet different seismic isolation design requirements. Background technique [0002] At present, known vibration-isolation rubber bearings are formed by stacking st...
