What are rubber bushings and how do they help in vibration isolation?

Rubber bushing is a kind of vibration isolator that serve as an interface between two mechanical parts, acting as a buffer and absorbing the energy produced by the two parts in motion. These bushings basically act as buffer that separates two parts while allowing them limited movement. This helps in minimizing the nuisance of vibration and noise produced in a machine.

Rubber bushings come in a variety of forms. They are designed into a cylinder shape and are encased in metal cases or in an outer tube. These rubber bushings are often preferable to solid connections as noise and vibration are limited. Also, installing of rubber bushing eliminate the use of lubrication between two parts.

Rubber bushings are widely used in a wide variety of application. Initially, they were used in anti-roll bars, shock absorber mountings, double wishbone suspensions, gear sticks and in the internal combustion engines of some cars. Eventually, these bushings were used in various other industrial application that generated vibration and noise.

Rubber bushings are also be used as shock absorbers, vibration insulators and abrasion resistors. Used with wires, pipes and tubing, these rubber bushings act as a seal. They are also used to help transfer load from one area in a structure to another, thus reducing strain.

Rubber bushings, an effective isolator for heavy duty industrial application

Anti vibration bushings also known as bushes or center bonded bushings that are rubber to metal bonded bushing mounts built for absorption of extreme static and dynamic forces in industrial & commercial applications. These rubber bushings are typically used in applications where the absorption of shock, attenuation of noise, limiting of the wear and tear and where elimination of lubrication is required.

The rubber bushings are designed to be loaded radially and utilize a soft torsion spring to provide freedom in rotation. They provide positive torsion positioning and pivot action under the most demanding operational conditions. But, while the high radial restraint maintains the alignment between joined parts, they are not intended for the use in applications where there is extreme rotational motion. So, the typical applications include, vibratory feeders, mobile power equipment and vibratory cable layers

At Andre HVAC International Inc, our fully bonded rubber bushings are designed of rubber compound, bonded to both inner and outer sleeves. These bushing vibration isolators are designed to eliminate high frequency vibration and noise, while supporting high loads in all directions. Also, the bushings are pre-loaded using a special process that assures a high resistance to the stresses involved during the operation.

The rubber bushes are manufactured in a wide range of metric sizes to suit a lot of industrial applications. We also sell these bushings designed in unique materials to suit your application requirements. Easy to install, the uncomplicated designs of the rubber bushings provide high strength bonding that assure, effective isolation and extended service life all at economical rate.

The typical application of these rubber bushing include vehicle engines, flexible joints, motor vehicles, auxiliary equipment, military, light and heavy duty equipment, farm, drilling equipment, harvesters, combines, cooling towers, earth moving machinery, general machinery,  industrial and construction machinery.

Vibration damping and isolation are the need of the hour

The rubber anti-vibration mounts and isolators have become a standard requirement as more and more people are becoming aware of the adverse effects of vibration and noise. Today, the isolation mounts are being widely used in refrigeration plants, compressors, HVAC equipment, diesel generators, fans, motors, pumps, presses and CNC machines etc. The elastomer can be natural rubber, neoprene or other compound depending on the requirement of resistance to ageing, compression set, water and oil. Let us take a look at the variety of the anti-vibration mounts and rubber hangers available.

Rubber grommets: The rubber grommet isolators provide the economical vibration isolation for light loads. The rubber bushings and rubber grommets are ideally suited for computers, disc drives, sensitive lab equipment and precision instrumentation.

Rubber bobbins: The rubber cylindrical mounts are also known as bobbin mounts and are used to curb both active and passive vibrations. The rubber dampers are effective in structure-borne noise control. A variety of combinations involving the stud and threaded hole at the two ends of the cylinder are available.

Rubber fan mounts: To prevent the transmission of vibrations from a fan motor to travel to the chassis, on which it is mounted, requires a rubber isolation mount to be put into place. The anti-vibration fan mount can be made from silicone and other rubber compounds in order to decouple the fan from the case and also attenuate the unwanted vibration.

a coil spring and carbon steel bases are ideally suited for mounting of HVAC equipment like fans, AHUs, pumps, and motors. The rubber in shear isolators is also used for HVAC applications where a higher degree of stiffness is required in the horizontal plane and good isolation in the vertical plane. Thus, the rubber in shear vibration isolators provides a cost effective engineered solution for HVAC equipment mounting.

Hard rubber mounts: The hard rubber mounts are desired for high reliability and fine quality requirements. The hard rubber anti-vibration mounts are custom built and find the usage in automobiles, machinery and household electrical appliances etc.

Rubber hangers: The anti-vibration hangers are used for false ceiling suspension, HVAC ducting and piping suspension, and equipment suspension. The rubber hangers are primarily made from polymer material while the spring hangers make use of metal springs.

Anti-vibration motor mounts: The equipment like hexacopters and multi-rotors make use of the anti-vibration motor mounts to attenuate the vibration and noise from motors and props. The flight controller sensors function properly only when the rubber anti-vibration mounts significantly dampen the motor vibrations.

Andre HVAC International Inc. is a leading supplier of rubber isolation mounts, rubber bushings, and HVAC rubber mounts to name a few. AHI uses the best of material to provide a long service life and enhance the life of the equipment. Whether you are replacing a worn out mount or going in for a new application, AHI has the right anti-vibration mounting to give you the desired vibration isolation and noise reduction.
