Types Of Shaft Couplings You Should Know

Couplings are mechanical elements responsible for 'coupling' two driver elements so that the motion gets transferred from one element to the other. These drive elements are mainly known as shafts and are often seen in automobiles. Shaft couplings add mechanical stability and prevent any problems caused by the misalignment. Couplings are categorized on the basis of their area of application and some of the most common types of shaft couplings are mentioned below:

Flexible Couplings

Flexible couplings are used in areas where the coaxially between connected shafts is not fixed. Also, the occurrence of shocks is very common in these areas where Ru-Steel flexible couplings are used. Flexible couplings are also known as elastic couplings. This is because when these couplings are made, an elastic member is added between two connecting entities.

Rigid Couplings

Rigid couplings are mostly made of aluminum and are used in control applications where two shafts are coaxial to each other. The two most common types of rigid couplings are:

  • Muff Couplings - These types of couplings consist of a hollow cylinder that is used to connect two shafts. The tolerance is based on the shaft size. There are two threaded holes to lock the coupling in position.
  • Flanged Couplings - As the name suggests, this type of rigid coupling consists of two flanged end pieces. The flanges are connected well with the help of fitted bolts which can be loosened or tightened according to the torque needed.

Bellows Couplings

Bellows couplings are suitable for motion control applications. The reason behind their use is being manufactured with multiple metal convolutions. These couplings offer torsional stiffness and stiffness is very necessary when it comes to positioning applications. You can expect to face fewer issues caused by angular and parallel misalignment if you're using bellows couplings. If you're planning to use these couplings, you can consider ST's metal bellow couplings as a reliable option.

Chain Couplings

Chain couplings are designed for power transmission applications. These couplings are capable of transferring hundreds of horsepower. The applications where chain couplings are used allow angular and parallel misalignment for about 2 degrees and 0.015 inches. You can find special chain sprockets and double large roller chains being installed within chain couplings.

Disc Couplings

Disc couplings consist of one or more disks and are considered power transmission devices. They transfer the torque and tolerate angular misalignment but are able to do so because of the thin metal disks which give them stability. You can find them installed in high horsepower engines and gas turbines.

Why Maintenance & Alignment Is Way Too Important For Coupling

Image
  As per our experiences and knowledge, extra care and attention are the keys when it comes to coupling maintenance. Regardless of the type and style of the coupling, you need to consider investing more time in the process since it gets the best possible life and performance out of it. Different types of coupling procedures can require different types of procedures and amounts of time.  Some require little to no maintenance at all. On the other hand, some may consume a significant amount of your time. For example, grid or gear coupling demands strenuous efforts for the coupling. Some additional steps are taken in the process in order to maximize both the life and performance of the coupling. Talking about insert and elastomeric coupling, it's easy to get done with. This is a type of coupling that requires very low maintenance. The best part about it is that the condition can be inspected visually during the operation with the help of a strobe.

Uses of ETP express bushes and Poly V Belts

  Poly V belts have taken over the usage from traditional V belts in a big way. The biggest consumers of V belts have been the manufacturers of white goods and automobiles, which have recently converted to the use of poly V belts in their application. Construction of poly V belts make it a much better choice for power transmission as they are more durable and offer better transmission of power. Types of poly V belts Flexonic belt As the name suggests, flexonic poly V belts are elastic belts with longitudinal ribs. These types of poly V belts are used for fixed center distance and their polyamide cord provides them the advantage. These are usually maintenance free V belts and tension in these V belts does not change in their life time. Conveyxonic V belts These V belts are elastic V belts specially designed for roller conveyers. This technology is the only V belt technology that can transport parcels ranging from 1 kg to 2 tons. This is a revolutionary technology that is being used in i

Types of Couplings – A Brief Overview

Image
A coupling is a mechanical device that connects two shafts together, especially for power transfer from the driver side to the driven side. The misalignment error is also considered during this power transfer between the shafts. Here, the operation incorporated or held differs from the clutch arrangement, in which, according to the operator's will, the power disengages and engages. STS Metal Bellow Couplings   join two shafts collinear or parallel to each other with the minimum tolerance or sectional gap between them.  The purpose of incorporating a coupling in the transmission of energy is as follows: a)  Power Transmission from the driving to the driven side. b) Consume the misalignment errors between the axes of the driving and driven side.  c) Consume the vibrations from the driving side that protects the overall system d) Not partaking in the heat transfer from the motor on the driver side to the driven side. The domestic electricity generator is the simple and most common exa
