Our chain couplings are engineered to excel in any application you need, with exceptional flexibility, strength, and a surprisingly simple assembly.

ABOUT ROLLER CHAIN COUPLINGS
A roller chain coupling is a mechanical device composed of a double-strand roller chain and 2 modified sprockets. The design is simple and highly effective, despite its small size, and is composed of a robust chain and specially cut, hardened-tooth sprockets that allow a high amount of torque to be transmitted.

BENEFITS OF GIL'S ROLLER CHAIN COUPLINGS
COMPACT AND POWERFUL

In a roller chain coupling, torque is distributed across the combined mating surfaces of each of the chain and sprocket pitches, which allows the coupling to handle a high amount of torque for its size. The chain connects closely with the sprockets, for a highly compact and lightweight coupling that transmits torque with the utmost efficiency.

SAFE AND SMART
Our compact roller chain couplings are housed in an aluminum casing that clamps to the sprocket hubs and rotates with the body of the coupling without the need for bolts or other projections. The coupling chain itself is easy to install and remove using a single connecting pin, so you save on installation labor and downtime.

EASY ALIGNMENT
When working with shafts in a drive, traditional rigid couplings require extremely precise alignment between the coupled shafts. Roller chain couplings introduce much-needed flexibility with clearances both in the chain and between the chain and sprocket teeth. With this added mobility, even with minor misalignment, chain couplings can operate in a smooth and responsive manner, reducing the potential for overheating and wear common in more rigid coupling designs. The operation of roller chain couplings is less affected by unavoidable shaft expansion and contraction. The flexibility and easy alignment of the drive shafts, when using chain couplings, will save time and money on equipment repairs and replacements.

HOW TO INSTALL A ROLLER CHAIN COUPLING
Install oil seal to each hub
Adjust the alignment of the shafts and coupling components
Adjust the distance between the sprocket faces
Thoroughly lubricate the coupling chain
Install chain to couplings using a single-pin connecting link
Firmly close and fasten the cover of the coupling (optional, depending on operating conditions)

flexible coupling

How does a flexible coupling handle electrical insulation between shafts?

Flexible couplings are typically not designed to provide electrical insulation between shafts. In most cases, flexible couplings are used solely for the purpose of transmitting mechanical power from one shaft to another while accommodating misalignment and absorbing shocks and vibrations. They do not offer any electrical isolation or insulation properties.

When electrical insulation is required between two rotating shafts in a system, additional components or specialized couplings are used. For applications where electrical isolation is necessary, insulated couplings or special insulation components can be employed. These types of couplings feature insulating materials, coatings, or designs that prevent electrical current from flowing between the connected shafts.

Insulated couplings can be beneficial in certain applications, such as electric motor drives or systems involving sensitive electronics. They help prevent stray currents, ground loops, and electrical interference that could potentially damage equipment or affect the accuracy of electronic signals. However, it is important to note that not all flexible couplings provide this electrical insulation capability, and users should carefully select couplings that meet the specific electrical isolation requirements of their application.

Summary: Flexible couplings, as standard mechanical components, do not inherently provide electrical insulation between shafts. They are primarily used for mechanical power transmission and misalignment compensation. If electrical insulation is needed between rotating shafts, insulated couplings or specialized components with insulating properties should be chosen to meet the specific requirements of the application.

flexible coupling

Can flexible couplings accommodate both radial and axial loads simultaneously?

Yes, flexible couplings are designed to accommodate both radial and axial loads simultaneously, making them versatile for various mechanical systems. The ability to handle these loads is one of the key advantages of using flexible couplings in power transmission applications. Here's how they manage both types of loads:

  • Radial Loads: Radial loads act perpendicular to the shaft's axis and can arise from forces that are not in line with the shaft, such as belt tension or bearing loads. Flexible couplings can handle radial loads due to their flexibility and ability to bend or deform slightly, redistributing the radial forces and minimizing the impact on the connected equipment.
  • Axial Loads: Axial loads act along the shaft's axis and are common in applications with thrust forces or axial movements. Flexible couplings can accommodate axial loads through their axial flexibility, allowing slight axial displacement without transmitting excessive forces to the connected components.
  • Angular Misalignment: Besides radial and axial loads, flexible couplings can also handle angular misalignment between the shafts. Angular misalignment occurs when the shafts are not perfectly aligned, and flexible couplings can compensate for this misalignment, reducing wear and stress on the connected machinery.

By accommodating both radial and axial loads, flexible couplings help prevent premature wear, reduce the risk of equipment damage, and contribute to smoother and more efficient power transmission. When selecting a flexible coupling for an application, it is essential to consider the expected radial and axial loads, as well as the required level of misalignment compensation to ensure optimal performance and longevity of the coupling and the connected equipment.

flexible coupling

What are the factors to consider when choosing a flexible coupling for a specific system?

Choosing the right flexible coupling for a specific system requires careful consideration of several factors. The following are the key factors that should be taken into account:

  • 1. Misalignment Requirements: Assess the type and magnitude of misalignment expected in the system. Different couplings are designed to handle specific types of misalignment, such as angular, parallel, or axial misalignment. Choose a coupling that can accommodate the expected misalignment to prevent premature wear and failure.
  • 2. Torque Capacity: Determine the required torque capacity of the coupling to ensure it can transmit the necessary power between the shafts. Consider both the continuous and peak torque loads that the system may experience.
  • 3. Operating Speed: Take into account the rotational speed of the system. High-speed applications may require couplings that can handle the additional centrifugal forces and balance requirements.
  • 4. Temperature Range: Consider the operating temperature range of the system. Select a coupling material that can withstand the temperatures encountered without losing its mechanical properties.
  • 5. Environment and Conditions: Evaluate the environmental conditions where the coupling will be used, such as exposure to moisture, chemicals, dust, or corrosive substances. Choose a coupling material that is compatible with the operating environment.
  • 6. Space Constraints: Assess the available space for the coupling installation. Some couplings have compact designs suitable for applications with limited space.
  • 7. Installation and Maintenance: Consider the ease of installation and maintenance. Some couplings may require special tools or disassembly for maintenance, while others offer quick and simple installation.
  • 8. Torsional Stiffness: Evaluate the torsional stiffness of the coupling. A balance between flexibility and stiffness is essential to prevent excessive torsional vibrations while accommodating misalignment.
  • 9. Shock and Vibration Damping: For applications with high shock loads or vibration, select a coupling with excellent damping characteristics to protect the system from excessive forces.
  • 10. Cost and Budget: Compare the cost of the coupling with the overall budget for the system. Consider the long-term cost implications, including maintenance and replacement expenses.

Ultimately, the choice of a flexible coupling should align with the specific requirements and operating conditions of the system. Consulting with coupling manufacturers or engineering experts can provide valuable insights to ensure the optimal selection of a coupling that enhances system performance, reliability, and efficiency.
