Rubber shock absorbers generally use natural rubber and chloroprene rubber. Nitrile rubber is required for oil resistance, silicone rubber is required for high and low temperature resistance, and butyl rubber is required for high damping. The manufacturing process of rubber shock-absorbing pad products is mostly similar to model products, except for rubber air springs that are similar to tires. Usually made into supports or connectors, widely used in various vehicles, ships, machinery, instruments, bridges, and buildings to eliminate or mitigate the adverse effects of vibration.
Application of rubber shock absorbers.
The main types of rubber shock absorber products include rubber shock absorbers, rubber air springs, rubber fenders (see color picture), sponge and cork rubber shock absorbers, elastic couplings, and flexible couplings.
For example:
① Rubber shock absorber pad. Most of them are rubber and metal composite products, with various forms such as double plate, cylindrical, and sheet, used for shock absorption and sound insulation of various machinery, instruments, axles, and pipelines.
② Rubber air spring. It has better shock absorption and impact resistance than metal springs, and is mainly used for vehicles. Its structure is somewhat similar to tubeless tires, with the curtain layer as the pressure resistant layer, an airtight rubber layer inside, and a protective rubber layer that is resistant to oil and aging outside.
③ Rubber bearings. Made by bonding rubber sheets with rigid materials such as steel plates, steel wire mesh, and canvas. The latter can improve the compressive strength of the support, while having little effect on the shear strength. Rubber bridge bearings can transfer bridge loads to piers and abutments, while also adapting to bridge deformation and reducing vibration. Rubber building bearings can reduce the impact of subways, surrounding vehicles, and earthquakes on buildings.
