What Is an Anti Vibration Pad?
An anti vibration pad is used to suppress vibration in a variety of equipment that generates vibration.
They are made of materials such as natural rubber and function simply by being placed under machinery. They are also cost-effective.
Many anti vibration pads have special patterns of irregularities on the surface, which reduces the spring constant and improves vibration control even if the pad is thin.
They can also be cut to the appropriate size, so they can be easily installed at the work site to suit the situation.
Uses of Vibration Absorbing & Isolating Pads
Equipment that generates vibration includes refrigerators and heat pumps. These are caused by the compression motion of pistons.
Machine tools such as milling machines and lathes also generate vibration, which can affect the accuracy of the workpiece.
In blowers and pumps, the blades rotate to discharge or suction gases. Vibration can occur during the collision of the blades with the gas and the subsequent compression process.
Anti vibration pads are also used to suppress vibration in printing equipment, sewing machines, generators, etc.
Principle of Vibration Absorbing & Isolating Pads
Many machines generate vibration and noise during their operation.
Refrigeration equipment and heat pumps use a gas compressor called a compressor. The piston moves back and forth during the compression process to change the gas to a high-temperature, high-pressure gas, which can easily cause vibration and noise.
Vibration also occurs in machine tools. For example, when cutting a surface on a milling machine or lathe, vibration can cause the surface to become uneven, which may prevent flat machining (called chattering vibration).
These vibrations, if they continue for a long time, can accumulate damage to the machine and reduce its original functionality. Physical damage can occur not only to the machine itself, but also to its surroundings.
Anti vibration pad can absorb these vibrations and impacts by utilizing the elasticity of rubber. They have a relatively long lifespan and provide stable anti-vibration and soundproofing performance.
Most are manufactured from natural or recycled rubber. Typical thicknesses are as thin as 10 mm to 20 mm, and they can be cut into large or arbitrarily sized pieces.
