Couplings are special elements with which you can build various designs and systems. Now we will understand what advantages the presented accessories have, as well as where they are used, what are they.
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 activity ;
- mechanical strength;
- resistance to external negative influences;
- providing excellent insulation and tightness of joints.
Naturally, couplings have certain disadvantages. Some types of the presented elements can deform, wear out (polyurethane), do not always absorb the vibrations of the system or mechanism.
Couplings
There are many types of elements presented depending on the scope and material of manufacture. Couplings are:
- Tough (made of metal). They are used in the assembly of various machines that have high structural qualities.
- Spiral (made from aluminum). Their feature is that they lend themselves to bending. This function is provided by the special structure of the accessory: it has transverse cuts.
- With polyurethane inserts. Such an element is characterized by the fact that between the two metal parts there is a shock-absorbing element. Due to such a structure, couplings can absorb a significant part of shock vibrations.
- Membrane. Their feature is that they are disassembled. They are often used to connect shafts of mechanisms that are angled to each other. Such an accessory is quite durable and functional.
A special type is a heat-shrinkable coupling. It is mainly used for firmly fixing three-core cables. An element is used in almost all cases of laying wires. Installing such couplings is very easy: they just need to be put on the cable at the connection and slightly warmed up. They fit the wires very tight, so their contact is very durable and well insulated.
Features of the application of the presented products
A coupling, the price of which ranges from 5 to 125 dollars per piece, is used in the installation of water and other types of pipes. In addition, using this element, cable networks are laid: telephone, high-voltage and others.
Also, the presented products can be used to connect:
- metal cables, ropes ;
- shafts;
- axles and rods;
- polyethylene pipes.
As for the areas of application, this includes shipbuilding, heavy and light industry, communications, the construction of large highways, water supply systems, the production of machine tools and mechanisms. A feature of such elements is that they can connect different in diameter products.
