rubber block

Basic characteristics of rubber blocks:

(1) The rubber block is made of multiple layers of rubber sheets. It has sufficient vertical stiffness to bear vertical loads, can transmit the reaction force of the superstructure to the pier, has good elasticity to adapt to the rotation of the beam end, and has large shear deformation to meet the horizontal displacement of the superstructure.

(2) Characteristics of rubber blocks: They have been widely used in bridge construction, hydropower projects, and house anti-seismic facilities. Compared with the original steel bearings, they have the advantages of simple structure, rubber blocks, easy installation, saving steel, low prices, simple maintenance, and easy replacement. The rubber blocks have low building height, which is beneficial to bridge design and cost reduction; they have good seismic isolation, which can reduce the impact of live loads and earthquake forces on buildings.
As an important shock-absorbing element, rubber blocks have been widely used in various machinery, automobiles, motorcycles, and water transportation vehicles. The rubber block for locomotives is one of the rubber products. It is used in various parts of the locomotive to reduce vibration, sound insulation, buffering and other functions. The structure of this product is relatively simple, including a central rubber cone, axle box tie rod spring, side bearing rubber pile, elastic wheels, elastic gears, transmission arcuate rubber blocks and ball joints, coupler rubber buffer blocks, etc., and is generally manufactured by molding.
