Couplings are special elements with which you can build various structures and systems. Now let's figure out what advantages the presented accessories have, as well as where they are used, what they are.
Advantages and disadvantages of couplings
These elements have certain advantages:
- light weight;
- ease and speed of installation;
- low cost;
- large number of varieties;
- use in various spheres of human activity;
- mechanical strength;
- resistance to external negative influences;
- providing excellent insulation and tight connections.
Naturally, connecting couplings also have certain disadvantages. Some types of the presented elements can be deformed, wear out (polyurethane), do not always absorb the vibrations of the system or mechanism.
Coupling types
There are many types of elements presented depending on the scopeapplication and material of manufacture. Couplings are available:
- Rigid (made of metal). They are used in the assembly of various machines that have high design qualities.
- Spiral (made of aluminum). Their feature is that they can be bent. This function is provided by the special structure of the accessory: it has cross 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 this structure, couplings can absorb a significant part of shock vibrations.
- Membrane. Their feature is that they understand. They are often used to connect the shafts of mechanisms that are located at an angle to each other. This accessory is quite durable and functional.
Heat-shrinkable coupling is considered a special type. It is mainly used for firmly fixing three-core cables. The element is used in almost all cases of laying wires. It is very easy to mount such couplings: they just need to be put on the cable at the junction and warmed up a little. They fit the wires very tightly, so their contact is very strong and well insulated.
Features of the application of the presented products
Connecting coupling, the price of which ranges from 5 to 125 dollars apiece, is used in the installation of plumbing and other typespipes. 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 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 products of different diameters.

Coins of the Soviet Union and modern Russia: what metal are coins made of, their features and varieties
The production of money on the territory of our country at all times was associated with a number of difficulties: the economy either developed or collapsed sharply, dragging faith in the Russian currency to the bottom, giving rise to massive disbelief in it and inflation. Now we have clear state standards for production and minting, all reforms are taking place gradually and accurately, but during the times of revolutions, civil and world wars, the question of what metal coins are made of in our country faded into the background
