Chain Coupling

Chain couplings are mechanical components used to connect two shafts. They feature two rows of roller chains that engage with sprockets on each shaft. Once connected, the shafts rotate to transfer motion via the coupling. Chain couplings come in various sizes and are designed to handle different torque capacities, making them versatile for a range of applications.

Parameters of Chain Couplings

The parameters of chain couplings, such as size, torque capacity, and alignment tolerance, are crucial because they directly impact the performance and efficiency of the coupling. Properly selected parameters ensure that the coupling can handle the required load, prevent misalignment issues, reduce wear and tear, and enhance the overall reliability and longevity of the system. Without the right parameters, the coupling could fail, leading to mechanical breakdowns and costly downtime.

Advantages of a Chain Coupling

A chain coupling is a transmission system that utilizes a single common chain to mesh with two parallel sprockets, effectively transferring power between shafts. Chain couplings come in various types, such as roller chain, toothed chain, and nylon chain couplings. They are valued for their simplicity, reliability, and low installation precision. Chain couplings are frequently chosen for shaft transmission in low-speed, high-torque applications due to their robust design and ability to handle significant loads.

One of the main advantages of chain couplings is their high-torque capability. Constructed with two flanges connected by a duplex roller chain, they can easily handle high-torque requirements and accommodate up to 2 degrees of misalignment, making them ideal for demanding applications. Additionally, chain couplings are easy to install, require minimal maintenance, and help maintain alignment between shafts while minimizing shock and vibrations during power transmission. Their compact design ensures smooth power transmission, especially in high-speed applications.

Applications of Chain Couplings

Chain couplings are primarily used in low to moderate-speed, high-torque applications and are less common in higher-speed scenarios where more advanced couplings like grid or gear couplings are preferred. Known for their rugged construction and ease of installation, chain couplings are ideal for applications such as line-shaft couplings on live-roller conveyors. In these cases, plastic chain couplings provide a lubrication-free solution, eliminating the need for covers or guards, as the smooth outer surface of the chain minimizes any catch hazards.

 

For general power transmission, chain couplings are available in a variety of shaft sizes and torque capacities, with bore diameters typically reaching up to 4-1/2 inches and torque capacities up to 220,000 in.-lbs. These couplings generally allow for an angular misalignment of 1° and a parallel misalignment of up to 2% of the chain pitch, though these limits may be reduced for higher-speed operations. Sprockets are sized in two-tooth increments to match roller chain links, and their pitch is based on ANSI standards like #40, #60, or #80. While manufacturers typically choose the correct sprocket size and pitch for torque requirements, knowing the pitch can assist in selecting replacement chains.

Ever-Power chain couplings are distinguished by their innovative single-pin design, which streamlines the installation process significantly. Here’s a straightforward guide to installing them:

  1. Place the oil seal on each hub.
  2. Align the shaft and coupling assembly.
  3. Adjust the distance between the sprocket faces.
  4. Thoroughly lubricate the coupling chain.
  5. Attach the chain to the coupling using the single-pin coupling ring.
  6. Securely close the coupling cover (optional, depending on operating conditions).

Compared to traditional rigid couplings, the installation of Ever-Power chain couplings is quicker and simpler, making them a practical choice for various applications.
