reducer coupling | High quality pipe fittings with low price

Coupling is a device for connecting two shafts in order to transfer power normally. Couplings do not allow the shafts to break apart during operation, although torque limiting couplings can be reached when the torque exceeds a certain level Slip or break. read more about the PVC reducer coupling, reducer coupling pipe fittings, PVC reducer coupling 4 to 3, reducer coupling sizes and reducer bush.

how many types of reducer coupling are there?

Clutch or pressure couplings are two pieces that are attached to the two shafts to form a sheath. These couplings are more flexible than the sheath models and can be used for fixed shafts. They are usually large enough that the screw can pass through the entire coupling and enter the second half to ensure safe holding.

Rigid flange couplings are designed for heavy loads or industrial equipment. These couplings consist of short sheaths formed by a perpendicular flange. A coupling is mounted on each shaft and thus two flanges are facing each other. Then a number of bolts or bolts can be installed in the flanges to fit together. Because of their size and durability, flange units can be used to align the shafts before they are connected. Rigid couplings are used when the shaft alignment is required. Shaft malfunctions affect performance as well as coupling life. Example:


The sheath coupling consists of a pipe whose inner diameter is in accordance with the tolerance required by the shaft. Depending on the need and application of the couplings, torque from a thorn and a thorn groove is used within it. To lock the couplings in place, two tape holes are created.

Sheath couplings are also known as box couplings. In this case, the ends of the shafts are coupled together against each other and covered by a sheath. A collapsing thug holds the two shafts together and sheaves together. Sheath couplings are the simplest type of couplings, usually made of cast iron. These couplings consist of a hollow tube piece with an inner diameter equal to the shaft diameter. The pipe is arranged on both ends of the shaft with the help of a cone-shaped submerged spur. Thorns and pods are suitable for transferring power from one shaft to another.


In this type of couplings, the pods are usually made of cast iron and are joined by steel bolts or bolts. One of the benefits of this coupling is that it is easy to mount and disassemble the couplings without moving the shafts. This coupling is used for high power transmission at medium speed.


The conical lock is in the form of a thorn less shaft locking piece that does not require any pieces to be removed from the shaft. The original idea is very similar to the clutch coupling, but closer to the center of the shaft when rotating.

This coupling device, which replaces the conventional parallel spur, eliminates the possibility of movement due to the wear of the spur groove. This piece is much sturdier than the thorn because it only requires one piece to hold and the spin balance itself indicates that it is durable than the thorn joint but more expensive.


The Hirth joint uses conical indentations on the two ends of the shaft, for torque transmission.


Flexible couplings are used to transfer torque from one shaft to another when two shafts are slightly angled. Flexible couplings can accommodate up to 3 degree and slightly parallel alignments. In addition they can be used for vibration attenuation or noise reduction. This coupling protects the shaft parts of the driver against the harmful effects produced by shaft malfunction, sudden force, expansion or shake vibration, and so on.

What are the most durable types of reducer coupling?

Knowing the design and coupling limitations helps an industrial designer engineer to make decisions easily. Each type of coupling has its limitations, which is why it requires us to choose the right coupling for each system and its specific conditions. Different couplings are suggested for different applications of different industrial systems. For example, if there is severe misalignment in the system, flexible coupling would be the best choice. Because it can compensate for the imbalance, thereby preventing any potential malfunction of the system.

Complex devices are usually not 2% aligned and need to be coupled using couplings. It should be noted that each coupling covers a certain level of deviation, so consider this before choosing a coupling. Pump shaft and motor are crucial. Therefore, it should not be allowed to exceed the permissible degree of mismatch of the selected coupling. This axisymmetric oscillation can cause the coupling to wear out and cause it to collapse earlier. For vertical systems, it is important to evaluate the coupling capabilities used in vertical weight bearing. For this purpose, couplings are added with special materials to withstand the extra load and to prevent excessive strain on the coupling.

Best reducer copuling for high pressure pipes

Couplings are divided into two main types of rigid and flexible couplings according to their structure and components:

The rigid couplings are designed so that they cannot withstand any shaft maladjustment. However, flexible couplings can withstand partially non-axial loads and allow the shafts to move forward and backward in the axial or radial direction. The type of couplings is selected according to their application to the device in question. They also need to be properly adjusted to ensure their useful life and effective power transfer. Otherwise, the bearings or shaft of the car may become damaged and damaged.

In order to transmit power from the drive to the drive by the couplings, both the drive shaft and the drive with acceptable tolerances must be aligned. Therefore, their coupling must be examined before coupling the two shafts by coupling. When for any reason the coupling of the propulsion machine is not aligned in one direction, so-called non-axial or non-axial coupling has occurred. The misalignment usually occurs due to a variety of causes, such as machine foundation displacement, accidental collision of the machine with other parts, thermal expansion, loosening of the retaining nuts, expansion and contraction of the device and the retainers and wires, which reduce the efficiency of the machine, Rapid destruction of car parts, increased energy losses, increased vibrations, bearing warming and many unforeseen crashes.
