Couplings: advantages, varieties and features of application

Couplings are special elements, with which you can build various structures and systems. Now let's look at the advantages of the presented accessories, as well as where they are used, what they are.

Advantages and disadvantages of couplings

These elements have certain advantages:

• Light weight;
• Simplicity and speed of installation;
• Low cost;
• A large number of varieties;
• Use in various spheres of human life;
• Mechanical strength;
• Resistance to external negative influences;
• Providing excellent insulation and tightness of joints.

Naturally, couplings have certain drawbacks. Some types of represented elements can deform, wear (polyurethane), do not always absorb the vibration of the system or mechanism.

Types of couplings

There are many types of presented elements depending on the scope and material of manufacture. Couplings are:

• Hard (made of metal). They are used in the assembly of various machines, which have high constructive qualities.
• Spiral (made of aluminum). Their peculiarity is that they can be bent. This function is provided with a special accessory structure: it has transversal cuts.
• With polyurethane inserts. Such an element is characterized in that there is a cushioning element between the two metal parts. Due to this structure, the couplings can absorb a significant part of the shock vibrations.
• Membrane. Their peculiarity is that they understand. They are often used to connect the shafts of mechanisms that are located at an angle to each other. Such an accessory is quite durable and functional.

A special type of heat shrinkable coupling is considered. It is used mainly to securely fix three-core cables. In almost all cases of wire laying, the element is used. Mounting such couplings is very easy: they just need to be put on the cable at the connection point and slightly warmed up. They are very tight around the wires, so their contact is very strong and well insulated.

Features of the application of the products

Coupling, the price of which ranges from 5 to 125 dollars per piece, is used for the installation of water and other types of pipes. In addition, using this element, cable networks are laid: telephone, high-voltage and others.

Also presented products can be used for connection:

• Metal cables, ropes ;
• Shafts;
• Axles and links;
• Polyethylene pipes.

As for the spheres of application, here it is possible to include shipbuilding, heavy and light industry, communications, construction of large mains, water supply systems, production of machine tools and mechanisms. A feature of such elements is that they can connect different diameter products.
