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.
