Rubber springs are a kind of high elastomer, and are made of ordinary rubber. Rubber springs have a small elastic modulus and a large elastic deformation after loading to absorb shock and vibration. It can be subjected to multidirectional loads at the same time, but has poor heat and oil resistance than steel springs. It can be made of oil-resistant rubber if special requirements are required. The product has good damping effect, small resonance field, long service life, low cost, good cold resistance, excellent air tightness, waterproof, electrical insulation, and is a good choice for vibration damping. zmjt052 Rubber Spring Features Rubber springs are not limited in shape, have large elastic deformation, easy to realize non-linear requirements, and have good vibration damping and sound insulation effects. Compared with rubber springs, composite rubber springs are limited in shape by metal coil springs, with high linearity requirements and heavy weight, but the advantages of large load-bearing capacity are not comparable to pure rubber springs. Advantages (1) the shape is not limited, the stiffness in each direction can be freely selected according to the design requirements; (2) the elastic modulus is small, can obtain large elastic deformation, and the ideal nonlinear characteristics can be easily realized; (3) it has high internal resistance, which has a good effect on the absorption and sound insulation of sudden shock and high-frequency vibration; (4) the same rubber spring can bear multi-directional load at the same time, so that the structure of the system Simplification; (5) Easy installation and disassembly, no lubrication, which is conducive to maintenance. Disadvantages (1) High and low temperature resistance and oil resistance are worse than steel springs; (2) Rubber springs used in engineering are simpler in shape than bellows, but it is difficult to accurately calculate their elastic properties.
