Coupling is a device used to connect two shafts to transfer power. Usually, the couplings do not allow the shafts to separate during operation, although torque limiting coupling pipe fitting can slip or separate when the torque exceeds a certain level.
What is a coupling pipe fitting?
The initial incentives for building a coupling should be sought in the wheels. In fact, if it weren’t for the wheel, the need to make such a piece would have been delayed for centuries.
Rotating machines are usually either actuators, such as electric motors, gas turbines, steam turbines, and internal combustion engines, and يا or moving ones such as compressors, pumps, blowers, ventilators, mixers, and power transmission from the actuator to the moving parts. Clutches, belts, gears, chains, etc. are used, each of which is used according to the type of machine in its specific conditions.
Coupling pipe plastic one of the mechanical power transmission systems that transfer torque from the drive shaft to the drive.
Couplings are divided into two main categories based on their structure and components: rigid and flexible couplings:
The rigid couplings are designed to withstand the unevenness of the shafts. But flexible couplings can tolerate somewhat uneven axes and allow the shafts to move forward and backward in a axial or radial direction. The type of couplings is selected according to their application in the desired device. They also need to be properly adjusted to ensure their useful life and effective power transmission. Otherwise, the bearings or shaft of the car may wear out and be damaged.
In order to transfer power from the drive to the drive by the couplings, both the drive and drive shafts must be aligned with an acceptable tolerance. Therefore, before connecting the two shafts by coupling, their alignment should be examined. When, for whatever reason, the coupling of a moving and moving machine is not in the same direction, the so-called heterogeneous or incoherent.
Misalignment usually occurs for a variety of reasons, such as shifting the fundus of the machine, accidental collision of the machine with other parts, thermal expansion, loosening of the retaining nuts, expansion, and contraction of the machine and holders, and rusting of the wires, reducing machine efficiency. Rapid destruction of machine parts, increased energy losses, increased vibrations, heating of bearings, and many unforeseen breakdowns occur.

This type of coupling is used to connect two axes in exactly the same direction in the equipment in which the exact axial alignment of the two axes is necessary and accessible. It should be noted that any axial asymmetry in this type of coupling causes rapid failures. The effect of high stress follows.
Hard couplings are used for axes, which are not inconsistent. Since these couplings cannot compensate for any deviations or discrepancies between the axes connected by them (rigid couplings), the axles must have a good lateral and angular balance.
Hard couplings are less commonly used than flexible ones. Hard coupling is not able to compensate for the misalignment of the axes, so it is useful in cases where the axles have a lateral balance and a precise angle.types of pipe fittings The presence of any misalignment between the axes causes high stresses and increases the load-bearing loads.
Hard couplings are commonly used in places with vertical actuators. Strict couplings not only transfer rotational motion from the actuator (usually an electric motor) to the rotating member of the system but also any axial motion (up and down) that occurs between two parts of a system’s equipment, also by coupling. The rigid ones are transferred between them. Due to the rigidity of the rigid couplings, the equipment used by these types of couplings to transfer motion must be perfectly aligned and have a precise axial alignment, and no deviations in this regard are acceptable.
