A sleeve is a device that is designed to connect pipes. In many mechanisms, models are used to clamp the shaft. If we consider the electrical circuit, then there the coupling connects the cable. The standard model consists of a housing, inlet and outlet, as well as clamping discs. To understand the issue in detail, you need to consider existing types of couplings and understand their features.
Model Types
By design, disc and cylindrical devices are distinguished. Additionally, there are sleeve modifications. They are divided into flange and cam models. Hinged devices are highlighted in a separate category. Disk modifications come with teeth or plates. Cylindrical models are divided into hydraulic, magnetic and friction devices.
Disk device sizes
These types of couplings (disk) are produced on 5, 8 and 10 cm. Models are used, as a rule, for clamping pipes. The diameter of the coupling can always be recognized by the inscription on the housing. Many modifications are made with double forks. Clamping rings are installed with overlays. It is also worth noting that the models stand out for their high strength. Cases 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.
Slave drives in the devices are located next to the adapter. The outlet may be overlaid. 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 discs often wear out. The tie plates are installed in steel or aluminum alloy.
Cone Modifications
Conical types of couplings are used to connect pipes. Some models are made with oval discs. There are devices with and without adapters. Clutch drums are cylindrical in shape. It should also be noted that there are modifications with clamping plates that are located in front of the housing.
Models differ not only in the number of drums, but also in the size of the outlet. The diameter of the casing is 5.5 cm on average. The models are great for water pipes. If we consider devices with one drum, then they have several clamps. Most couplings are made with one fork. Connecting devices through the pipe.
Cylindrical electromagnetic devices
The cylindrical electromagnetic coupling is suitable for wires. Cables in this case are clamped through the plates. Partitions for models are in front of the case. A standard cable gland is made with two adapters. The fingers of the modifications are located 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 made with a diameter of 5.5 cm or more. The output clamps differ in size. It should also be noted that often there is a coupling for a cable on double springs. Coupling racks are used with heads. An electromagnetic clutch works by rotating the plates.
Features of multi-disc split models
These types of couplings (multi-disk) are found in different areas. Modern models are made with contact adapters. Disks for devices are convex in shape. The standard coupling (detachable) has only one rack. Partitions for such devices are made with a small gap. If we consider models with two adapters, then they have several clamps.
To connect the shafts of the device are not bad. Drums are mounted with bearings or rollers. If we talk about the benefits of modifications, it is important to mention that the coupling (detachable) does not need lubrication. Experts say that models of this type are very firmly fixed on the screeds, 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
A compressor clutch with one drum may have one or more disks. Many models work by rotating the fingers. In this case, the plates can be installed behind the adapter. If we consider a standard coupling for water supply, then it has three discs. In this case, the base plate is used of a large thickness. Devices withstand pressure at 5 bar.
Many modifications are able to boast of a robust body. Couplers in devices are installed through racks. Driven plates are typically located at the rear of the chassis. It is also worth noting that there are couplings on one-way adapters. They pass water in only one direction.

Flange coupling (steel) is available in diameters from 7 cm. Drums for devices are suitable for clamping type. On average, the limit pressure indicator is at 4 bar. Adapters for devices are used with overlays. Drives are most often used cast type. To stabilize the device, springs are used. 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. Clips 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, they have a case diameter of 8 cm.
Hinge Models
Hinged couplings are characterized by a high coefficient of stability. Pads for 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 models can 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.
Clamp the rings on the adapter. Seals 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. The drums for the couplings are selected conical shape.
Cam devices
Cam couplings are often used for sewer systems. Many models use double discs. They are clamped by a plate with a small lining. Experts say that devices can withstand significant pressure. Housing sizes are different. On average, the diameter of the coupling is 5.5 cm. The drive plates are used only with clamps. Cams are made with heads of different sizes. If we consider a simple modification, then it has two outlet openings. Additionally, a neck is used to fill the oil. Most devices have a driven plate, which is located behind the adapter. Rings in this case are absent.
Drive Models
Drive devices 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. Specialists 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 the fingers. Additionally, there is a chamber for oil supply. The bearing row is located behind the adapter. Many couplings have a long tip for connection. Screeds are used in different shapes. The minimum diameter of the case is 3.5 cm.
Rigid couplings
Rigid couplings are required to securely hold the shaft. Modern models stand out with wide clamps. Cases in devices are always made with casings. It should also be noted that there are couplings on the adapters. Most of them work from clamping disks. In turn, the plates move away from the rollers. The pressure indicator for models, as a rule, does not exceed 6 bar.
Push plates can be installed in front of the adapter. Slave drives are used with double overlays. Channels vary in length and diameter. Modifications with release plates are distinguished by large sizes. They are great for milling machines.

At the same time, the racks are located in front of the device. Many models work due to disks. Bearings are used with squeeze plates. Ties on some couplings are fitted with a guard ring.
These devices are great for narrow shafts. Most models are compact in size. Drums are used with threaded protrusions. 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 coupling is able to work for a long time. However, it is important to consider that the models have a low pressure parameter. Seals for most couplings are missing. It is also necessary to mention that modifications are not distinguished by their security. Couplers quite often can fly out.
