Types of couplings, purpose, classification, dimensions

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 the coupling connects the cable. The standard model consists of a body, an inlet and an outlet, and clamping disks. In order to understand the issue in detail, it is necessary to consider the existing types of couplings and to understand their features.

Types of models

By design, disc and cylindrical devices are isolated. In addition, there are bushing modifications. They are divided into flange and cam models. In a separate category are allocated devices on the hinges. Disk modifications come with denticles or plates. Cylindrical models are divided into hydraulic, magnetic and friction devices.

Dimensions of disk devices

These types of couplings (disk) are produced at 5, 8 and 10 cm. Models are used, as a rule, for clamping pipes. Diameter of the coupling can always be found from the inscription on the case. Many modifications are made with double forks. Clamping rings at them are established with overlays. It is also worth noting that the models are distinguished by their high strength. Enclosures are not provided in all couplings. Some models are distinguished by the presence of bearings. Typically, the length of the clutch is 5.5 cm.

The slave drives in the devices are next to the adapter. The outlet can be with an overlay. The models are suitable for pipes of different diameters. Installation of couplings of this type does not take much time. Speaking of disadvantages, it is important to note that the devices need maintenance. In this case, the driven discs often wear out. The clamping plates are made of steel or aluminum alloy.

Cone modifications

Cone types of couplings are used for connecting pipes. Some models are made with oval discs. There are devices with and without adapters. Drums for couplings are cylindrical in shape. It should also be noted that there are modifications with tie plates that are in the front of the case.

Models differ not only in the number of drums, but also in the size of the outlet. The diameter of the body is on average 5.5 cm. The models are remarkably suitable for water pipes. If we consider devices with one drum, then they have several clamps. Most couplings are made with one fork. Connect the devices through the pipe.

Cylindrical electromagnetic devices

The cylindrical electromagnetic coupling is suitable for wires. Cables in this case are clamped through the plates. The partitions at the models are in the front part of the case. A standard cable clutch is made with two adapters. The fingers of the modifications are at 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. The output terminals they differ in size. Also it should be noted that a coupling for the cable on double springs is often found. Tie racks are used with heads. The electromagnetic clutch operates due to the rotation of the plates.

Features of multi-disk split models

These types of couplings (multi-disc) are found in different areas. Modern models are made with contact adapters. Disks for devices fit a convex shape. The standard coupling (detachable) has only one rack. Partitions at such devices are made with a small gap. If we consider the models for two adapters, then they have several clamps.

To connect the shafts of the device are not bad. Drums are installed with bearings or rollers. If we talk about the advantages of modifications, it is important to mention that the coupling (detachable) does not need lubrication. Experts say that this type of model is very firmly fixed on the screeds, and they have a small wear of 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

A single-drum compressor clutch may have one or more discs. Many models work by rotating their fingers. In this case, the plates can be installed behind the adapter. If we consider the standard clutch for a water pipe, then it has three discs. In this case, the support plate is of a large thickness. Devices can withstand a pressure of 5 bar.

Many modifications are capable of boasting a durable body. Screeds in devices are installed through the racks. The driven plates are generally located at the rear of the housing. It is also worth noting that there are couplings on one-way adapters. They pass water only in one direction.

Models with several drums

Couplings with several drums are available in different sizes. Most often there are modifications to 20 and 25 cm. Devices of this type are great for home water systems. Some couplings are made for drives. Drums in devices can be installed with denticles. The oil for them is poured through the neck, which is in the upper part of the body. Many models are made on squeeze plates. Also it should be noted that there are simple modifications on one spring. These models have one or more disks.

Intended use of viscous bushing models

The viscous coupling is used in electrical circuits. The models are available with clamping plates. They are equipped with a special fuse, which is capable of withstanding large overloads. It is also worth noting that there are wired couplers with insulators. Tensioners for modifications are suitable for different classes. Screeds are used, as a rule, with overlays. Experts say that the models are installed in transformer substations. Cables are mounted through a special input. The tensioners can be located at the front or rear of the housing.

Advantages of flange devices

The flange coupling (steel) is available in diameters from 7 cm. Drums for devices are suitable for clamping type. The average pressure limit is 4 bar. Adapters for devices are used with overlays. Discs are most often cast type. Springs are used to stabilize the device. It should also be noted that there are channel modifications.

The flange is clamped in a special chamber. The devices are suitable for large diameter pipes. The clamps are of a bilateral type. Slipping plates is provided by the presence of bearings. Some models are used in sewer systems. On average, they have a diameter of 8 cm.

Models on hinges

Couplings on hinges have a high coefficient of stability. The lining of the models is made of rubber. If we consider a standard clutch, then it has two pairs of disks. The central plate is at right angles. Experts say that models can work long. However, it is important to consider the high cost of the goods. First of all, this is due to the fact that models have special rings. As a rule, they are made of copper.

The rings on the adapter are clamped. Sealants are used in various forms. If we consider models for pipes of small diameter, then they use cylindrical tips. The heads can be made with a small stand. Drums for couplings are selected in a conical shape.

Cam devices

Cam clutches are often used for sewage systems. Many models use double discs. They are clamped with a plate with a small lining. Experts say that the devices can withstand considerable pressure. The dimensions of the cases are different. The average diameter of the clutch is 5.5 cm. Lead plates are only used with clamps. Cams are made with heads of different sizes. If we consider a simple modification, then it has two outlets. In addition, a neck for oil filling is used. Most devices have a slave plate that is located behind the adapter. There are no rings in this case.

Models for drives

The drives are capable of withstanding a pressure of 5 bar. 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 made with casings. Most devices are equipped with channel adapters.

If we consider contact models, they have a push mechanism. It works by moving your fingers. In addition, there is an oil supply chamber. The bearing row is located behind the adapter. Many couplings have a long connection tip. Screeds are used in different shapes. The minimum diameter of the body is 3.5 cm.

Rigid couplings

Rigid couplings are necessary in order to reliably hold the shaft. Modern models are distinguished by wide clamps. Enclosures in devices are always manufactured with casing. It should also be noted that there are couplings on the adapters. Most of them work from clamping discs. In turn, the plates move from the rollers. The pressure indicator for the models, as a rule, does not exceed 6 bar.

Pressure plates can be installed in front of the adapter. Slave discs are used with double overlays. Channels vary in length and diameter. Modifications with squeeze plates are large. They are great for milling machines.

Hinged devices

The hinged tube-tube coupling is produced with inclined discs. Most models are equipped with one drum, which is in the channel. The pin in the devices can be of large diameter. If we consider a flawed modification, then it has one adapter. Pressure plates are used with overlays. At the same time, the sealant is fixed on the casing. 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 the bearings. For them, a plate is installed under the drum.

Assignment of cogged models

Toothed couplings are necessary for connecting 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 in front of the device. Many models work at the expense of disks. Bearings are used with pressing plates. Screws in some couplings are installed with a protective ring.

These devices are great for narrow shafts. Most models have compact dimensions. Drums are also used with rifled projections. The squeeze plates are installed at an angle. If we talk about the advantages of such devices, it is important to note that the pipe-pipe coupler is capable of long work. However, it is important to consider that the models have a low pressure parameter. Seals for most couplings are missing. Also, it should be mentioned that the modifications are not distinguished by their security. Screeds can often fly out.

Devices with asterisks

Couplings with asterisks are capable of supporting high revs. The indicator of permissible pressure at them starts from 3 bar. In this case, the casing is made with casing. Many models have a drum with rifled projections. The covers are installed only on the front rings. In the back of the structures, as a rule, there are adapters.

Also, the couplings are equipped with special oil filling nozzles. If we talk about the parameters, then the diameter of the body is on average 5.5 cm. The springs are designed for a load of 6 N. Slave plates are installed at an angle of no more than 30 degrees. Some modifications are made with plugs. The outlet holes are located at the bottom of the structure. It is also important to mention that there are couplings on the channel adapters. Rings for such devices are suitable only with dual settings. Most models are made with thin plates of small size.

Centrifugal elastic modifications

The centrifugal elastic coupling is produced with movable disks. Many modifications have a contact adapter that works with the plates. It is also worth noting that the coupling is fitted with a load disk. He is behind the drum, and plays the role of stabilizer. Many models have a retainer. The plug is most often welded to the bottom of the case. The inlet pipe is installed with a diameter of 2.2 cm. Also, the elastic coupling has a post, and the adapter is of the channel type.

Polypropylene friction devices

The coupling (polypropylene) is suitable for water supply systems. The driven plates of the models are made with overlays. Pressing discs are most often installed with an adapter. It should also be noted that the rotation of the drum is carried out with the help of bearings. A conventional coupling (polypropylene) is equipped with an integrated adapter. If necessary, oil can be poured. The drive pinion is always attached to the pin. If we consider a conventional clutch, then it has a small protrusion in the rear of the hull. They do not have a plug.

Purpose of overtaking models

Overtaking couplings are designed for machine operation. The devices are mounted on the shaft and fastened with clamps. Most modifications have only two adapters. Pressure plates are used in different thicknesses. Some devices are made with casing, so they can withstand heavy loads. Also it should be noted that there are clutches with fingers. They are installed near the adapter. The partitions in this case are at right angles. Bearings for models of this type are not used.

Features of hydraulic models for compressors

Hydraulic couplings are used in industry for connecting shafts. As a rule, they are installed on machines of different capacities. The cases in the devices are made of different diameters. The adapter for the connection is in the front of the models. The locking discs can be equipped with a gear. The overlays are of a small thickness and are placed near the drum. Also it should 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.
