Durable Rubber Wheel Pads with Shock Absorption and Heat Resistance
Characteristics of rubber:
Rubber shock absorbers are widely used due to their effective utilization of the following characteristics of rubber:
1. High elasticity and viscoelasticity.
2. Large deformation and small modulus compared to steel material.
3. Greater impact stiffness than dynamic stiffness, and greater dynamic stiffness than static stiffness, making it conducive to reducing impact and dynamic deformation.
4. The shape and hardness of rubber can be easily adjusted to meet different requirements for stiffness and strength in different directions.
Rubber springs are high elastic bodies made of ordinary rubber material, and they are designed to absorb shock and vibration. Due to their small elastic modulus and large elastic deformation after load, rubber springs are capable of withstanding multiple loads at the same time. However, they are not as heat-resistant or oil-resistant as steel springs, though special oil-resistant rubber materials can be used to overcome these limitations.
Rubber springs have several advantages, including good vibration reduction effect, small resonance field, long service life, low cost, good cold resistance, excellent air tightness, and waterproofing. They also offer excellent electrical insulation and are an ideal choice for vibration reduction in various applications.
Application:
Rubber springs are mainly used in vibration machinery, double-decker buses, trucks, and other industrial machinery. They are commonly used in mechanical equipment, vehicle walking mechanisms, suspensions, and for vibration reduction and buffering. The versatility of rubber springs allows them to be designed into various structural forms according to specific work requirements, making them suitable for a wide range of applications.
In addition to the above-mentioned applications, rubber springs are also used in the construction of buildings and bridges, as well as in the aerospace industry. They are used to reduce the vibration caused by earthquakes, wind, and other external forces, and to protect structures and equipment from damage. In the aerospace industry, rubber springs are used to isolate sensitive equipment from the vibration and shock caused by aircraft engines and other sources.
Rubber springs have many advantages over other types of springs, including their ability to absorb energy, their resistance to corrosion and abrasion, and their ability to withstand high loads and shocks. They are also more durable than other types of springs, require less maintenance, and are more cost-effective in the long run.
