A coupling is a device that is designed to connect pipes. In many mechanisms, models are used to clamp the shaft. If we consider electrical circuits, then there the coupling connects the cable. The standard model consists of a body, inlet and outlet, and clamping discs. To understand the issue in detail, you need to consider the existing types of couplings and understand their features.
Model Types
By design, disk and cylindrical devices are distinguished. Additionally, there are sleeve modifications. They are divided into flange and cam models. Hinged devices are allocated in a separate category. Disc modifications come with teeth or plates. Cylindrically, the models are divided into hydraulic, magnetic and friction devices.
Disk drive sizes
These types of couplings (disc) are produced in 5, 8 and 10 cm. Models are used, as a rule, for clamping pipes. The diameter of the coupling can always be found by the inscription on the body. Many modifications are made with double forks. Clamping rings are installed with pads. It is also worth noting that the models are distinguished by high strength. Covers are not provided in all couplings. Some models are distinguished by the presence of bearings. As a rule, the length of the coupling is 5.5 cm.
Driven drives in the devices are next to the adapter. The exit opening can be with an overlay. Models are suitable for pipes of different diameters. Installation of couplings of this type does not take much time. If we talk about the shortcomings, it is important to note that the devices need maintenance. In this case, the driven disks often wear out. Tie plates are installed in steel or aluminum alloy.
Cone modifications
Conical types of couplings are used to connect pipes. Some models are produced with oval discs. There are devices with adapters and without them. Clutch drums fit cylindrical shape. It should also be noted that there are modifications with tightening plates that are located in the front of the case.
Models differ not only in the number of drums, but also in the size of the outlet. The body diameter is on average 5.5 cm. Models are great for water pipes. If we consider devices with one drum, then they have several clamps. Most couplings are made with a single fork. Devices are connected through a pipe.
Cylindrical electromagnetic devices
Cylindrical electromagnetic clutch suitable for wires. The cables in this case are clamped through the plates. Partitions for models are located in front of the case. A standard cable sleeve is made with two adapters. The fingers of the modifications are locatedat an angle of 30 degrees. It should also be noted that the models are used in mechanical power devices.
If we consider modifications with fuses, they are produced with a diameter of 5.5 cm or more. Their output clamps differ in size. It should also be noted that a double spring cable clutch is often found. Tie rods are used with heads. The electromagnetic clutch works due to the rotation of the plates.
Features of multi-disk plug-in models
These types of clutches (multi-disc) are found in different areas. Modern models are made with contact adapters. Disks for devices fit a convex shape. The standard coupling (split) has only one stand. Partitions for such devices are made with a small gap. If we consider models for two adapters, then they have several clips.
Devices are good for connecting shafts. Drums are installed with bearings or rollers. If we talk about the advantages of modifications, it is important to mention that the coupling (split) does not need lubrication. Experts say that models of this type are very firmly fixed on the ties, and they have little wear on the plates. Cases can be made of stainless steel or brass. There are also modifications made of aluminum alloy. They withstand high temperatures and are often installed in residential buildings.
Single drum models
Single drum compressor clutch can have one or more discs. Many models work by rotating the fingers. In this case, the plates can be installedbehind the switch. If we consider a standard coupling for water supply, then it has three discs. In this case, the base plate is used with a large thickness. Devices withstand a pressure of 5 bar.
Many modifications are capable of boasting a durable body. Ties in devices are installed through racks. The driven plates are usually located at the rear of the case. It is also worth noting that there are couplings on one-way adapters. They only let water through in one direction.
Multi-reel models
Multi-drum clutches are available in different sizes. The most common modifications are 20 and 25 cm. Devices of this type are great for home plumbing systems. Some clutches are made for drives. Drums in devices can be installed with teeth. Oil for them is poured through the neck, which is located in the upper part of the body. Many models are made on wringing plates. It should also be noted that there are simple modifications on one spring. These models have one or more discs.
Assignment of viscous sleeve models
Viscous coupling is used in electrical circuits. Models are available with clamping plates. They are equipped with a special fuse that can withstand large overloads. It is also worth noting that there are wire couplings with insulators. Tensioners for modifications fit different classes. Ties are used, as a rule, with overlays. Experts say thatmodels are installed at transformer substations. Cables are mounted through a special entrance. Tensioners can be located on the front or rear of the case.
Advantages of flanged devices
Flange coupling (steel) is available with a diameter of 7 cm or more. Drums for devices are suitable for clamping type. On average, the limiting pressure is at the level of 4 bar. Adapters for devices are used with overlays. Disks are most often used cast type. Springs are used to stabilize the device. It should also be noted that there are channel modifications.
Their flange is clamped in a special chamber. The devices are suitable for large diameter pipes. Clamps are applied bilateral type. The sliding of the plates is ensured by the presence of bearings. Some models are used in sewer systems. On average, their body diameter is 8 cm.
Hinged Models
Hinged couplings have a high stability factor. The pads on the models are made of rubber. If we consider a standard clutch, then it has two pairs of discs. In this case, the central plate is at a right angle. Experts say that the models are able to work for a long time. However, it is important to consider the high cost of the goods. This is primarily due to the fact that the models have special rings. As a rule, they are made of copper.
The rings on the adapter are clamped. Seals are used in various forms. If we consider models for pipes of small diameter, then they use cylindrical tips. In this case, the heads can be made with a small stand. Drums for couplings are selected with a conical shape.
Cam devices
Claw couplings are often used for sewer systems. Many models use double discs. They are clamped with a plate with a small lining. Experts say that the devices can withstand significant pressure. Case sizes vary. The average coupling diameter is 5.5 cm. Leading plates are used only with clamps. Cams are produced with heads of different sizes. If we consider a simple modification, then it has two outlets. Additionally, a neck for filling oil is used. Most units have a follower plate behind the adapter. There are no rings in this case.
Drive Models
Drivers capable of withstanding 5 bar pressure. As a rule, flange modifications are used. Many models use two pairs of discs, and the plates are installed with overlays. Experts say that couplings can be produced with casings. Most devices are equipped with channel adapters.
If we consider contact models, they have a push mechanism. It works by moving the fingers. Additionally, there is a chamber for supplying oil. The bearing row is located behind the adapter. Many couplings have a long connection tip. Ties are used in different forms. The minimum case diameter is 3.5cm.
Rigid Couplings
Rigid couplings are needed to securely hold the shaft. Modern models are distinguished by wide clips. Enclosures in devices are always produced with enclosures. It should also be noted that there are couplings on adapters. Most of them work from pressure disks. In turn, the plates move from the rollers. The pressure indicator for models, as a rule, does not exceed 6 bar.
Press plates can be installed in front of the adapter. Driven discs are used with double overlays. Channels vary in length and diameter. Modifications with squeeze plates are distinguished by their large dimensions. They are great for milling machines.
Articulating devices
The pipe-to-pipe swivel coupling is produced with inclined discs. Most models are equipped with one drum, which is located in the channel. The pin in the devices can be of large diameter. If we consider a whipped modification, then it has one adapter. Pressure plates are used with overlays. In this case, the seal is fixed on the casing as standard. Most devices are made with rings. Flanges on many models do not have a rack. It should also be noted that there are devices on bearings. For them, a plate is installed under the drum.
Assignment of gear models
Gear couplings are needed to connect shafts in mechanisms. Most devices are equipped with one drum. If we talk about chain modifications, then they use two ties. In this case, the racks are infront of the device. Many models work at the expense of disks. Bearings are used with push plates. Ties on some couplings are installed with a protective ring.
These devices are great for narrow shafts. Most models are compact. Drums are used with threaded ledges. The push plates are set at an angle. If we talk about the advantages of such devices, it is important to note that the pipe-pipe coupling can work for a long time. However, it is important to consider that the models have a low pressure parameter. Most couplings do not have seals. It should also be mentioned that modifications are not distinguished by their security. Ties can fly out quite often.
Star devices
Couplings with sprockets are able to maintain high speeds. The permissible pressure indicator for them starts from 3 bar. In this case, the cases are made with casings. Many models have a drum with threaded protrusions. Overlays are established only on forward rings. Adapters are usually located at the back of the structures.
Also, couplings are equipped with special necks for filling oil. If we talk about the parameters, then the diameter of the case is on average 5.5 cm. The springs are designed for a load of 6 N. The driven plates are installed at an angle of no more than 30 degrees. Some modifications are made with forks. Their outlets are located at the bottom of the structure. It is also important to mention that there are sleeves on the channel adapters. Rings for suchdevices are only suitable with double adjustments. Most models are made with small casting plates.
Centrifugal elastic modifications
Centrifugal flexible coupling is made with moving discs. Many modifications have a contact adapter that works with plates. It is also worth noting that a load disk is installed at the clutch. It is located behind the drum, and plays the role of a stabilizer. Many models have a holder. The fork is most often welded to the bottom of the body. The inlet pipe is installed with a diameter of 2.2 cm. Also, the elastic coupling has a stand, and the adapter is used channel type.

Coupling (polypropylene) suitable for plumbing systems. The driven plates of the models are made with overlays. Squeeze discs are most often installed with an adapter. It should also be noted that the rotation of the drum is carried out using bearings. Conventional coupling (polypropylene) is equipped with a built-in adapter. If necessary, oil can be added. The drive gear is always mounted on a pin. If we consider a conventional clutch, then it has a small protrusion in the rear of the housing. They don't have a fork.
Assignment of passing models
Overrunning clutches are designed to operate machine tools. The devices are mounted on a shaft and fastened with clamps. Most modifications have only two adapters. Pressure plates are used in different thicknesses. Some devices are made with casings, so they can withstandbig loads. It should also be noted that there are couplings with fingers. They are installed near the adapter. Partitions in this case are at right angles. Bearings are not used for models of this type.
Features of hydraulic models for compressors
Hydraulic couplings are used in industry to connect shafts. As a rule, they are installed on machines of different capacities. Cases in devices are made of different diameters. The connection adapter is located at the front of the models. Closing disks can be with gear. Linings are used with a small thickness and are placed near the drum. It should also be noted that there are many models with elongated adapters. Such devices are suitable for large diameter shafts. Pins in couplings are used with a piston. There are no springs in this case.
