An engine mount’s primary purpose is to secure an engine into machinery and absorb any shocks and vibrations when the machinery is operating. The anti-vibration properties of engine mounts are essential for preventing damage to the engine and improving operator comfort (where applicable). But what happens when engine mounts need replacing? And, do you know the symptoms of worn engine mounts? We answer both of these questions in this post.

Engine mounts are an essential component of your machine or vehicle, connecting the engine to the chassis. They are designed to absorb shocks, vibration and noise during operation, which is crucial for preventing damage to both the motor and the chassis. This post discusses the different types of engine mounts available, their pros and cons, and compares solid rubber vs hydraulic motor mounts.

As a leading specialist in rubber vibration mounts, we offer our extensive expertise using a step by step guide to help you choose the correct rubber mounts. Read on to read our easy to follow guide to choosing the best anti-vibration mount to suit you.
What are Anti Vibration Mounts?
Anti-vibration mounts are fastened to machines to eliminate vibration and noise. Machinery vibration from equipment can be transferred to the supporting structure and travel large distances to be emitted as noise elsewhere in a building or structure. The mounts are typically made of rubber or a combination of rubber and other materials. Rubber vibration mounts are particularly effective in preventing the transfer of vibrations that machines generate.

An air spring system provides a cushion between the vehicle body and wheel to reduce the vibration felt during travel. This blog will explain air spring systems and discuss air suspension advantages and disadvantages, to give you a better understanding of how they work. In particular, it will cover the benefits of air suspension when used in cars, but some of the principles carry over to heavy vehicles like trucks, tractor-trailers and passenger buses and trains.

In the past few years, there has been a dramatic increase in the recycling of plastics and paper, with more and more people becoming aware of the positive economic effects recycling can bring. But other products can be recycled that people are not as aware of, such as rubber. Recycled rubber products can be used in many ways, but how is rubber recycled? And what are the advantages and disadvantages of recycling rubber? In this guide, we cover all of these questions and explain the rubber recycling process in more detail.

When selecting an anti-vibration mount, it is always important to consider what would happen if the rubber was overloaded due to improper use and the rubber were to fail. In this context, it is useful to be able to categorise mounts as either captive or non-captive. The images below show the fundamental difference between the two.

Originally, in July 2017 the government announced a ban on the sale of any new diesel, petrol or hybrid cars by 2040, in an effort to dramatically reduce air pollution. This comes as a strand of a larger plan to attempt to emit zero carbon by 2050. As such, as of February 2020, the banning of petrol and diesel cars by 2040 was brought forward to 2035 “if possible“.

Many properties of rubber make it the ideal material for anti-vibration products. To conserve these properties it’s important that the rubber is protected from environmental conditions, such as light and heat, that might otherwise degrade it. Consideration should also be given to protecting the metal that the rubber is often bonded to, as this can also be affected by these conditions.

A rubber compound is produced by adding specific chemicals to raw rubber material in order to improve and alter the characteristics of the rubber for desired use. Selecting the correct rubber compound is vitally important for any application. There are many types of rubber and GMT have a wealth of experience in selecting and manufacturing the right compound to suit customer requirements. Using our in-house computer controlled automated mixing systems, we can ensure the correct formulation is produced based on the many thousands that GMT have developed previously.

In the modern age, with our ever-increasing environmental awareness, it’s no wonder that the renewable energy industry is thriving, and in the UK in particular, wind farms. Whilst in its most basic form, wind power has existed since 5000 BC in the form of wind-propelled boats, and the first electricity-generating wind turbine was built in 1887, modern wind power became part of mainstream British society in 1951, and has been flourishing ever since. Due to this prominence, wind power is a keen area of interest to GMT.

The Department of Transport has released a new report stating that Railways have now become the second most-used mode of transport in the UK, second only to cars. This demonstrates that, as roads have become more convoluted, people are making use of the UK’s rail service more and more. This is especially true for those living outside of a city centre but travelling into it for work. Driving into a city during rush hour normally means adding extra time onto your commute. This means that travelling by train can be a much more convenient and appealing option, but only if they are running efficiently. To keep customers happy, trains need to be consistently on time, comfortable, and able to run efficiently during peak times.

Suspension bushes are a type of vibration isolator that is often made of rubber. The purpose of a suspension bush is to prevent metal-to-metal contact while still allowing for some movement. The movement is essential for allowing parts of the suspension to move freely. Although small, suspension bushes largely influence the efficiency of a vehicle, playing an important role in the safety, comfort, and handling of a vehicle. Due to the constant exposure to the elements underneath a vehicle, deterioration of suspension bushes can occur over time.
It’s therefore important to check your suspension bushes.

How We Use 3D Modelling
Special software allows us to plan out and accurately represent the object we have in mind. Connecting geometric shapes, curved surfaces, and lines, the 3D model gives a mathematical description of the surface of the object. Here at GMT Rubber, if standard products are not suitable to a client, we are able to produce a new design using 3D modelling. This is used in conjunction with Finite Element Analysis (FEA).
With knowledge of the client’s needs, we build a product to meet the specification whilst ensuring that the finished design is also capable of meeting service life/durability requirements.
