Chain couplings are mechanical devices for connecting two shafts. They consist of two rows of roller chains with sprockets that engage them. The shafts are then cranked to move the coupling. Chain couplings are available in a range of sizes and torque capacities.

The chain coupling is composed of a duplex roller chain and a pair of coupling sprockets. The function of connection and detachment is done by the joint of the chain. It has the characteristic of being compact and powerful, excellent durability, safe and smart, simple installation and easy alignment. The chain coupling is suitable for a wide range of coupling applications.

What Are Chain spojnice?

Chain couplings are mechanical devices for connecting two shafts. They consist of two rows of roller chains with sprockets that engage them. The shafts are then cranked to move the coupling. Chain couplings are available in a range of sizes and torque capacities.

Chain couplings are all steel and compact for space-constrained applications. They transmit high torques and offer positive power transmission. Unlike conventional couplings, chain couplings require less space and are easily installed and dismantled. They also provide a balanced unit operation, which is essential for high torques. Chain couplings are typically used in low-speed, high torque applications. They also offer a high degree of flexibility and allow for misalignment of up to 2 degrees between the shafts.

Advantages of a Chain Coupling

A chain coupling is a type of transmission system that uses a single common chain, meshing with two parallel sprockets to transfer power from one shaft to the other. A chain coupling comes in various varieties, including roller chain coupling, toothed chain coupling, and nylon chain coupling. The benefits of a chain coupling include its simplicity, reliability, and low installation accuracy. A chain coupling is a common option for shafting transmission applications, especially in low-speed, high-torque applications.

One of the most important advantages of chain couplings is their high-torque capability. Because they are made of two flanges linked by a duplex roller chain, they are ideal for high-torque applications. They can accommodate up to 2 degrees of misalignment, which makes them a common choice for applications that require high torque. Another advantage of chain couplings is their ease of installation and low-maintenance requirements.

Besides being easy to assemble, a chain coupling also keeps the two shafts perfectly aligned. It also minimizes shock and vibrations during power transmission. It should also have a low-profile design and be easy to fit between two shafts. And, of course, it should be able to transmit power from one shaft to the other. These features are essential for high-speed applications.

How to Install a Roller Chain Coupling?

Ever-power chain couplings feature a unique single-pin design that greatly simplifies the installation process. Simply follow these simple steps.

  • Install the oil seal on each hub
  • Adjust the alignment of the shaft and coupling assembly
  • Adjust the distance between the sprocket faces
  • Thoroughly lubricate the spojni lanac
  • Install the chain to the coupling using the single pin coupling ring
  • Firmly close and secure the coupling cover (optional, depending on operating conditions)

The chain coupling installation process is simpler and faster than conventional rigid couplings.
