橡胶垫的目的是什么？

橡胶减震产品主要包括橡胶减震垫，橡胶气弹簧，橡胶挡板（参见彩色图片），海绵和软木橡胶减震垫，弹性联轴器和柔性管。

例如：

　　①Rubber cushion. Most of them are rubber and metal composite products, with double-plate, cylindrical, sheet and other forms, which are used for shock absorption and sound insulation of various machinery, instruments, axles, and pipelines.

　　②Rubber air spring. It has better shock absorption and impact resistance than metal springs, and is mainly used in vehicles. Its structure is somewhat similar to that of a tubeless tire, with the ply as the pressure-resistant layer, an airtight rubber layer inside, and an oil-resistant and aging-resistant protective rubber layer outside.

　　③Rubber bearing. It is made by bonding rubber sheet and rigid material (steel plate, steel wire mesh, canvas). The latter can improve the compressive strength of the bearing, but has little effect on the shear strength. The rubber bridge bearing can transmit the bridge load to the pier and abutment, and at the same time can adapt to the deformation of the bridge and reduce the vibration. Rubber building supports can reduce the impact of subways and surrounding vehicles and earthquakes on buildings.
