A koppeling is a gadget used to connect two shafts collectively at their ends for the intended purpose of transmitting power.
Couplings do not normally allow disconnection of shafts during operation, however right now there are torque limiting couplings that may slip or disconnect when some torque limit is exceeded.
The primary reason for couplings is to join two pieces of rotating equipment while permitting some extent of misalignment or end movement or both.

3 haadsoarten koppelingen:
1. Rigid coupling a rigid coupling is usually a unit of equipment used to join two shafts within a engine or mechanical system. It could be used for connecting two separate systems, such as a engine and a generator, or to fix a connection within an individual system. A rigid coupling may also be added between shafts to lessen shock and wear at the main point where the shafts meet.
When joining shafts within a machine, mechanics can choose between flexible and rigid couplings. While flexible units present some movement and present between your shafts, rigid couplings will be the most reliable choice for precise alignment and secure hold. By precisely aligning both shafts and keeping them firmly set up, rigid couplings help maximize performance and raise the expected existence of the machine. These rigid couplings can be found in two basic designs to fit the demands of different applications. Sleeve-style couplings are the least expensive and easiest to make use of. They consist of an individual tube of materials with an inner diameter that’s equal in size to the shafts. The sleeve slips over the shafts so they meet in the center of the coupling. A number of set screws can be tightened therefore they touch the very best of each shaft and keep them set up without passing completely the coupling.
Clamped or compression rigid couplings come in two parts and match together around the shafts to create a sleeve. They offer more flexibility than sleeved versions, and can be used on shafts that are set in place. They generally are large enough to ensure that screws can pass completely the coupling and in to the second half to make sure a secure hold.
Flanged rigid couplings are designed for large loads or industrial equipment. They contain short sleeves surrounded by a perpendicular flange. One coupling is placed on each shaft so the two flanges line up face to encounter. A number of screws or bolts can then be installed in the flanges to hold them jointly. Because of the size and durability, flanged models can be used to provide shafts into alignment before they are joined collectively. Rigid couplings are utilized when exact shaft alignment is necessary; shaft misalignment will have an effect on the coupling’s performance in addition to its life.
2. Flexible coupling versatile couplings are accustomed to transmit torque in one shaft to some other when both shafts are slightly misaligned. Versatile couplings can accommodate varying levels of misalignment up to 3° and some parallel misalignment. Furthermore, they may also be utilized for vibration damping or noise decrease.This coupling is utilized to protect the driving and driven shaft members against harmful effects produce because of misalignment of the shafts, sudden shock loads, shaft expansion or vibrations etc.
3. Torque limiter coupling made to slip the torque from the shaft to prevent harm to the engine or the application
What is the difference between rigid coupling and flexible coupling?
Couplings are split into groups: Rigid and Flexible. In comparison withflexible couplings, rigid couplings have limited application. Rigid couplings do not have the capability to compensate for shaft misalignments and are therefore used where shafts are already positioned in exact lateral and angular alignment.

Flexible couplings accomplish the objective of any coupling, but their advantageover rigid couplings is they accommodate the unavoidable misalignment between shafts in a few machinery. Flexible couplings also allow for a amount of axial movement between the coupled shafts as may occur because of thermal expansion.

Elastomeric Couplings – This contains jaw type and S-flex couplings.
Couplings are products used to connect two shafts together and so are divided into two categories: Rigid and Flexible. Both are used for the objective of transmitting power, rigid couplings being even more limited in applications when compared with versatile couplings. Rigid couplings are utilized where shafts are already positioned in exact lateral and angular alignment. Their design does not enable any misalignment between shafts, but are usually able to transmit more power than flexible couplings. Versatile couplings are designed to accommodate misalignment between shafts and different types of load conditions. Many styles and types of couplings are available. For effective coupling selection, application circumstances should be clearly understood.
