Product Description
Product Description
A beam coupling, also known as helical coupling, is a flexible coupling for transmitting torque between 2 shafts while allowing for angular misalignment, parallel offset and even axial motion, of 1 shaft relative to the other. This design utilizes A single piece of material and becomes flexible by removal of material along a spiral path resulting in a curved flexible beam of helical shape. Since it is made from a single piece of material, the Beam Style coupling does not exhibit the backlash found in some multi-piece couplings. Another advantage of being an all machined coupling is the possibility to incorporate features into the final product while still keep the single piece integrity.
Changes to the lead of the helical beam provide changes to misalignment capabilities as well as other performance characteristics such as torque capacity and torsional stiffness. It is even possible to have multiple starts within the same helix.
The material used to manufacture the beam coupling also affects its performance and suitability for specific applications such as food, medical and aerospace. Materials are typically aluminum alloy and stainless steel, but they can also be made in acetal, maraging steel and titanium. The most common applications are attaching encoders to shafts and motion control for robotics.

Simultaneous Handling of Axial Motion and Angular Misalignment by Beam Couplings
Beam couplings are designed to handle both axial motion and angular misalignment simultaneously in motion control systems. Their unique helical beam design allows them to accommodate various types of misalignment, providing flexibility in multiple axes. Let’s explore how beam couplings achieve this:
1. Axial Motion:
Beam couplings can compensate for axial motion, which occurs when the two connected shafts are not collinear and have some linear offset along their common axis. The helical beams of the coupling can elongate or compress to absorb the axial movement between the shafts. This axial flexibility enables the coupling to maintain a continuous and efficient connection even when the shafts experience slight linear displacement.
2. Angular Misalignment:
Angular misalignment refers to the situation where the two shafts are not perfectly aligned and are at an angle to each other. Beam couplings handle angular misalignment by allowing the helical beams to flex, bending at an angle to accommodate the misaligned shafts. The flexible beams can twist and adjust their shape as needed, providing a reliable connection between the shafts and transmitting torque efficiently.
3. Simultaneous Handling:
What makes beam couplings advantageous is their ability to handle both axial motion and angular misalignment simultaneously. As the shafts experience angular misalignment, the helical beams can flex to compensate for the misalignment angle. At the same time, if there is any axial motion between the shafts, the beams can elongate or compress to absorb the linear offset. This simultaneous handling of axial motion and angular misalignment allows beam couplings to maintain smooth operation and effective torque transmission even in applications with complex misalignment requirements.
It is essential to select the appropriate size and type of beam coupling based on the specific application’s misalignment characteristics and torque requirements. Properly installed and maintained beam couplings can provide reliable and efficient performance, ensuring accurate motion control and extended system life.
Safety Considerations for Installing or Using Beam Couplings in Industrial Setups
When installing or using beam couplings in industrial setups, several safety considerations should be taken into account to ensure the safe and reliable operation of the motion control systems. Here are some important safety considerations:
- Proper Installation:
Ensure that beam couplings are correctly installed according to the manufacturer’s instructions. Follow the recommended torque values for tightening set screws or clamps to avoid over-tightening or under-tightening, which could lead to coupling failure or excessive wear.
- Shaft Alignment:
Accurate shaft alignment is crucial to prevent unnecessary stress on the coupling and connected components. Misalignment can lead to premature wear, vibrations, and reduced system performance. Utilize alignment tools and techniques to achieve precise shaft alignment within the coupling’s specified tolerances.
- Overloading:
Avoid exceeding the beam coupling’s rated torque capacity or maximum axial load. Overloading the coupling can lead to deformation, coupling failure, or damage to connected equipment. Ensure that the coupling is appropriately sized for the application’s torque requirements.
- Regular Inspection:
Perform routine inspections of beam couplings to check for signs of wear, damage, or misalignment. Address any issues promptly and replace worn or damaged couplings to prevent unexpected failures.
- Environmental Conditions:
Consider the operating environment when selecting beam couplings. Different materials offer varying levels of resistance to corrosion, temperature extremes, and other environmental factors. Choose a material that can withstand the specific conditions of the industrial setup.
- Protective Enclosures:
If the beam couplings are exposed to moving parts or hazardous equipment, consider using protective enclosures or guards to prevent accidental contact and ensure operator safety.
- Regular Maintenance:
Follow a regular maintenance schedule for the entire motion control system, including beam couplings. Lubricate moving parts as recommended by the manufacturer and replace worn components to maintain reliable operation.
- Training and Awareness:
Ensure that personnel involved in the installation, operation, and maintenance of the motion control system are properly trained and aware of safety procedures. Emphasize the importance of following safety guidelines to prevent accidents and injuries.
By taking these safety considerations into account, industrial setups can enhance the safety and efficiency of their motion control systems. Regular maintenance, proper installation, and adherence to safety guidelines are essential to ensuring the longevity and reliable performance of beam couplings and the overall safety of the workplace.
Handling Misalignment and Compensating for Shaft Offset in Beam Couplings
Beam couplings are designed to handle misalignment between connected shafts and compensate for shaft offset in motion control systems. Their flexible and helical beam structure allows them to accommodate various types of misalignment, ensuring smooth and reliable operation. Here’s how beam couplings handle misalignment and compensate for shaft offset:
- Helical Beam Design:
Beam couplings consist of one or more helical beams, which are thin, flexible metal strips arranged in a helix shape. The helical beam design gives beam couplings their characteristic flexibility, allowing them to bend and twist in response to misalignment and shaft offset.
- Angular Misalignment:
If the connected shafts are not collinear and are at an angle to each other, it results in angular misalignment. Beam couplings can handle angular misalignment by allowing the helical beams to flex, bending at an angle to accommodate the misaligned shafts. The flexibility of the beams enables the coupling to transmit torque smoothly even when the shafts are not perfectly aligned.
- Axial Misalignment:
Axial misalignment occurs when the two shafts are not on the same axis or are not aligned in the same line. Beam couplings can compensate for axial misalignment by permitting the helical beams to elongate or compress in the axial direction. This axial flexibility allows the coupling to accommodate the offset between the shafts without causing excessive stress on the components.
- Parallel Misalignment:
Parallel misalignment refers to the situation where the two shafts are not at the same height or parallel to each other. Beam couplings handle parallel misalignment by permitting the helical beams to shift laterally. This lateral movement allows the coupling to adjust to the offset between the shafts and maintain an effective connection.
- Compensation Range:
Beam couplings have a specified range of misalignment they can accommodate. The amount of misalignment they can handle depends on the number of helical beams and the design of the coupling. Multi-beam couplings typically have a higher misalignment compensation range compared to single-beam couplings, making them more suitable for applications with more significant misalignment requirements.
- Limitations:
While beam couplings can compensate for a certain degree of misalignment, they do have limitations. Excessive misalignment beyond the coupling’s rated capacity can lead to premature wear, increased stress on the components, and reduced coupling performance. It’s essential to operate the beam coupling within its specified misalignment limits to ensure optimal functioning and longevity.
In summary, beam couplings handle misalignment and compensate for shaft offset by virtue of their flexible helical beam design. The ability to bend, twist, elongate, and shift laterally enables them to accommodate angular, axial, and parallel misalignment in motion control systems. Choosing the appropriate beam coupling type and staying within its rated misalignment range are essential to ensure effective compensation and reliable operation in various applications.
