Rubber mounts and rubber isolators for vibration and noise dampening in industrial machines

In Industrial engineering or in any manufacturing industry, most of the sound or noises are generated through rotating machine components that travel to the entire structure and mounting floor. The movement of machine parts result in high frequency sounds, vibration, and noise that affects the stability of structure and also results in the wear and tear of a highly accurate machine components.   Vibrational energy has its own independent effect on every machine tool components, which results in to uncertain machine break down and productivity loss. Technically, vibrational energy is a form of mechanical energy that moves through objects and disrupts the normal operation. In order to reduce the effect and transfer of vibrations, a scientific approach is adopted wherein vibration in any system is managed by either isolating it or by dampening it. Equipment’s like rubber mounts and vibration isolators are used for isolation of vibrating machines in the industry.

By installing rubber mounts or vibration isolation system, they prevent high frequency vibration from entering the system and dissipating the machine. Vibration isolation systems for mechanical components require some amount of damping. Damping dissipates mechanical energy from the system and attenuates vibrations more quickly. Without damping, the system will vibrate and ultimately lead to break down of the machine. One of the cheapest and best form of vibration isolator and dampening device is Rubber mounts.

Rubber mounts are usually made of neoprene or cork that are used in equipment mounting stage. Rubber mounts or rubber isolators are installed when mounting the machine.  This installation acts as a dampening layer between vibrating source and vibration receiver. It plays a vital role in industrial systems that face constant vibration issues. So, when induced with vibration it dissipates the energy by deflecting itself, ensuring minimum transfer of energy and regains its original position. Application and the area of source, which needs to be damped plays a decisive role in selecting the optimum size of rubber mounts. While there are rubber isolators as well that are used for small equipment to supplement air-handler internal isolation, or where there is little to no acoustical sensitivity.

Rubber Isolation mounts are majorly designed from cork and neoprene. They are available in many sizes solely dependent upon application. In situations where the cork pads lack to serve the purpose of vibration isolation, an alternative rubber isolator crafted from neoprene pad is used, which yields more deflection and better vibration isolation. Another factor to be taken in to account while selecting rubber isolators is the operating frequency at which the source transfers energy to the receiver. Frequency plays a vital role in selecting the form and structure of rubber mounts and isolators. Complex internal structure and variable density of dampening material used in developing rubber mounts and isolators, offer desired results and is suitable for various application. Rubber mounts and isolators prove to be very effective equipment’s that help control vibration and noise issues especially at a very reasonable operating cost.
