Compression-Load Rubber Isolation Mounts:

In the industrial landscape – be it manufacturing or construction, vibration control is not just an operational concern; it’s an imperative. One of the key players in this sector is the Compression-Load Rubber Isolation Mount.

Designed to curb and control vibrations, these mounts have found myriad applications across sectors. But what makes them so effective? Let’s dive deep into their anatomy, functionality, and the benefits of using rubber as the core material, using the Megafoot range as a running example.

What are Compression-Load Rubber Isolation Mounts?

Simply put, Compression-Load Rubber Isolation Mounts are specialized hardware components that serve as a barrier between a vibrating machinery and its mounting surface. The primary goal is to absorb the vibrational energy emitted by machinery, thereby preventing its transference to surrounding structures.

Spotlight on Megafoot

For instance, the Megafoot Anti Vibration Mounts from Isolgomma are designed for direct installation onto machinery. This is particularly beneficial for environments where space is at a premium or where installing inertia bases is not feasible.

Anatomy of a Compression-Load Rubber Isolation Mount

When we look at the design components of these mounts, we find them to be seemingly simple yet highly effective pieces of engineering.

Rubber Element

At the heart of each mount is a rubber element. In the case of the Megafoot range, this insert is made of selected Styrene-Butadiene Rubber fibers (SBR) and rubber granules, hot-pressed with polyurethane glue.

Metal Plates

Flanking this rubber insert are metal plates. These provide the points at which the machinery is fixed to the mount. The Megafoot mounts use shaped stainless steel plates that are threaded at the top and bottom for secure fixing. They also offer notched fixing points for additional anchoring options.

Fastening Elements

To ensure that everything stays in place, fasteners like screws or bolts are used. Depending on the model of the Megafoot mount, specific M-threaded fixings like M6, M8, M10, or M14 are used.

Operational Mechanics

So how does this assembly work in curbing vibrations?

Energy Absorption

The rubber insert is the primary component responsible for absorbing vibrational energy. When machinery is operational, it generates vibrations. These vibrations are initially absorbed by the rubber element in the mount.

Energy Dissipation

Post absorption, this energy is converted into heat and then dissipated. This function is particularly noteworthy in the Megafoot range, which is designed to prolong the life of machinery by providing effective dampening.

Extending Machinery Lifespan

The Megafoot mounts not only absorb and dissipate vibrations but also extend the life of the machinery by isolating it from external sources of vibrations. This is particularly useful in industrial settings where machinery is subject to significant amounts of shock and vibration.

Why Rubber Is Ideal

Rubber’s unique set of properties makes it ideal for this application:

  1. High Elasticity: Rubber can revert to its original shape after deformation, making it perfect for absorbing and releasing vibrational energy.
  2. Damping Characteristics: Rubber’s inherent damping properties are essential for the effective conversion of vibrational energy into heat.
  3. Versatility: The Megafoot range, for example, offers variable rubber densities and can support loads up to 10,000 kg, making rubber a versatile choice.
  4. Noise Reduction: Rubber also acts as an effective noise absorber, reducing the ambient noise in an industrial setting.
