Product Description

The lead shock insulation rubber bearing is fused press-in lead core together with rubber bearing to follow shear deformation.This kind of bearing is a shock isolation device with all in one damping structure which is made of a recovery device stabilized by rubber bearing and a lead energy absorbing device. Lead is a kind of metal with good plastic deformation capacity and energy absorption capacity. The lead rubber bearing is one of the earliest bearings used in isolation structure. Lead rubber bearing has been widely used in engineering because of its excellent mechanical properties, simple structure and higher cost performance .

Types of Rubbering Bearing

1.According to the Isolation property points
(1)Ordinary rubber isolation bearing
(2) Lead rubber bearings
(3)High-performance isolation bearings
(4)Three-dimensional isolation bearing
2.According to the vibration territory point
(1)Floating vibration isolation track/board support
(2)Cultural relics isolation box
(3)vibration isolation platform
(4)Bridge isolation bearing

Technical parameter

Vertical bearing capacity: 204kN - 21206kN

Design angle: 0.006rad and 0.008rad

Equivalent damping ratio: >10%

The displacement of the bearing: the design displacement of sliding bearing in bridge axial direction is ±100mm and ± 150mm.

The horizontal displacement of the bridge is ±30mm, and the normal shearing strain is 1.0, and the scale of earthquake is about 2.0.

Friction coefficient :the design friction coefficient of sliding bearing is 0.03.

Applicable temperature range: -40ºC-60`ºC

Product characteristics

1. Put vertical bearing capacity, horizontal restoring force and damping (energy absorbing) these three characteristics into one ;

2. The hysteretic characteristic (load-deformation curve)of the bearing is plumper and the energy consumption is significant;

3. Rubber formula improving and equivalent damping ratio can reach more than 12%;

4. Low maintenance and management costs (no need of other damping devices);

5. Residual deformation is minimal after earthquake and do not need replacement;

6. The surface of high damping bearing is covered with rubber protective layer, which can protect the inner rubber from ozone and ultraviolet rays, and has better aging resistance. And decrease amplitude of equivalent damping ratio is less than 2% in 50 years;

7.HDR high damping rubber has low temperature dependence.And it can be widely used in different climatic regions;

8.HDR high damping rubber has superior creep properties as natural rubber;

9. Environmental and non-pollution.
