Sandwich mounts are used in a wide variety of mechanical applications. They help in supporting a kind of equipment from engine suspension to rubber isolation feet etc. Hence if you want to buy these crucial parts for your mechanical device, it’s important that you pick a high-quality product that will work properly and have a longer lifespan.
These mountings are available in various shapes, sizes & materials. So before you purchase your product, you need to do a proper analysis of the type of mount you require. Sujan Industries is the manufacturer and supplier of premium quality sandwich mountings & other various rubber products in India and abroad. And here in this guide, we’ve tried to give you an overview of this crucial product and help you choose your best one.
The name “sandwich mount” was given to this part due to its shape. Two or more metal plates are used to sandwich a rubber piece. These parts are often used for anti-vibration, noise absorption, high compression, heavy load requirements. These mounts ensure a rubber break between two metal surfaces since each side of the sandwich is connected to each side with rubber in the middle.
If used as a motor mount, they will ensure the minimum movement, vibration and transfer of the vibration of the engine to the car frame. Apart from that, the sandwich mounting also reduces damage and enhances the lifespan of the internal parts like the engine and the frame. And this way they protect the machine and the operator from the damage caused by such unwanted and unnecessary vibration.
That combination is what makes these mounts so useful. You get support for heavy static loads while still taming vibration in more than one direction at the same time.
Different sandwich mounts come in different shapes, as we have already mentioned. And because of this, all of the mounts don’t have the same parts. However, the general construction of a sandwich mounting is as follows:
◉ Metal plates & Inserts: Metal plates are found at both ends of the mount.
◉ Rubber: The rubber part is placed between the sandwich plates. It helps to minimize vibration and noise.
◉ Threads: There can be different types of screw threads in the sandwich mountings. A screw thread is a hump that wraps around the part.
◉ Stud: The stud of any sandwich mounting comes through the plates and the piece of rubber. It may be visible only on one side of the mount.
However, some of the mountings might have rectangular or square sandwich plates with round rubber parts, while others have only one stud or no studs at all.
High Compressive Load and Performance Characteristics
Sandwich Mounts are designed to meet the challenges presented by high compressive load conditions. Prominent performance features of sandwich mounts are:
◉ Performance to Stack Loads: Allows for the mount to support large loads while still providing a degree of flexure to isolate vibration.
◉ Support Surface Area: Provides a large support area while keeping the overall thickness f the mount to a minimum.
◉ Radial Flexure: Provides the equipment mount system the ability to isolate and/or decrease shock and/or vibration
◉ Natural Frequency: When a system of sandwich mounts is used to provide isolation, the natural frequency of the system may be adjusted by changing the stack height.
These characteristics are ideally suited for the requirement of equipment isolation in high load conditions such as in marine equipment and locomotive/rail equipment.
Selecting the correct sandwich mount comes down to a few key engineering factors. Use this checklist before finalizing your specification:
Our technical team at Sujan Industries works directly with customers to evaluate these factors and recommend the ideal material, plate configuration, and mounting design for the application.
Using premium quality sandwich mountings can get you a lot of benefits like the following:
◉ Simple design: These mountings have a simple design, have different types, and can offer space-saving solutions. Mainly because of the minimal design, the mounts can offer the right solution to the size and mounting requirements.
◉ Can carry heavy loads: Sandwich mounts come in a broad range that has the capacity to carry heavy loads.
◉ Have high strength bond: High strength bonding is another benefit of the mountings. These parts are generally rubber-to-metal bonded parts and hence they stick together.
◉ Provides high compressive strength: These mounting provide especially high compression.
◉ Controls energy: Sandwich mountings exhibit excellent energy control. It protects the key parts from getting damaged by the vibrations.
◉ Easy to install: Due to the size and simplicity of the design, these mounts are easy to install and run.
◉ Requires little or zero maintenance: Rubber is such a material that requires very little maintenance. And hence after installing these sandwich mountings you don’t need to put any extra effort into their maintenance. Only need to replace them whenever required.
◉ Automotive and Commercial Vehicles
Sandwich mounts are found in both passenger vehicles and in the heavy-duty trucks and trailers that comprise the North American freight movement. Engines in heavy-duty trucks generate high levels of vibration. Using a sandwich mount isolates the powertrain vibration from the vehicle cab and reduces the levels of vibration felt by the driver. Fatigued drivers are unsafe drivers.
◉ Rail and Other Guided Transportation
Rail mounted vehicles are exposed to very different service conditions than road vehicles. Long service intervals, combined with continuous dynamic loads, increase the demands placed on the mounts used in vehicles. Rubber sandwich mounts are used to decrease vibration in rail vehicles. Wheel/rail interface vibration can adversely affect the service of rail passenger vehicles and other rail equipment.
◉ Marine and Offshore
Mounts for marine service must accommodate the high levels of vibration produced by marine propulsion systems. Marine Sandwich mounts are used in a V configuration to isolate the equipment and reduce the levels of vibration experienced by the marine structure and personnel.
◉ Mining and Off-highway Vehicles
Equipment used in mining is subjected to extremely high and variable loads. Continuous vibration from the equipment can cause operator fatigue. Using a sandwich mount helps reduce operator fatigue and increases the service life of the cab structure. Large sandwich mounts in crushers provide a high static load capacity while isolating and dampening vibration.
◉ Aerospace and Defense
Vibration control in aerospace applications is critical, as sandwich mounts in an aircraft provide isolation between systems and components which are separated by a large difference in magnitude in regard to stiffness. Sandwich mounts are required to withstand varying temperatures and maintain their isolating properties for long periods of time. Isolation of electronic payloads in land-based defense systems from mechanical vibration and shock is essential.
◉ HVAC, Power Generation, and Industrial Equipment
Steady-state vibration in components such as compressors, pumps, and generators, can lead to failure of adjacent and support structures and increase equipment fatigue. Isolation of this vibration is essential. Sandwich mounts are used to decouple equipment in HVAC and industrial systems from support structures.
◉ Agriculture and Forestry
Harvesters and other agricultural equipment which covers large areas, does so for long periods of time. Vibration isolating mounts for engines and cabs help reduce the vibration and shock that the operator is subjected to.
When you need sandwich mounts that you can rely on, come to Sujan Industries. Our mounts are manufactured from high quality materials to withstand even the most arduous of applications. All of our mounts are manufactured to the requirements of ISO 9001 and IATF 16949. This shows you the quality is real and steady each and every time.
Our recognition and adherence to these globally recognized quality standards, means that you can expect steady and reliable vibration isolation mounts for your automotive and other machinery.
In order to ensure the safety of your equipment and provide adequate vibration isolation, it is important to select the sandwich mount best suited to the conditions of the environment in which it will be used. Some of the considerations may include the temperature range and type of fluids (if any) which it may be exposed to. The frequency of the vibration which the mount is required to isolate and the type and amount of the load which the mount is required to support are also important considerations. It is important to consider how the mount will be secured to the supporting surface (i.e. vertically or horizontally).
