Product Description
LMS Model Flexible Double flange type jaw coupling for pump
Description:
A jaw coupling is a type of general purpose power transmission coupling that also can be used in motion control (servo) applications. It is designed to transmit torque (by connecting 2 shafts) while damping system vibrations and accommodating misalignment, which protects other components from damage. Jaw couplings are composed of 3 parts: 2 metallic hubs and an elastomer insert called an element, but commonly referred to as a “spider”. The 3 parts press fit together with a jaw from each hub fitted alternately with the lobes of the spider. Jaw coupling torque is transmitted through the elastomer lobes in compression.
The elastomer of the spider can be made in different materials and hardness, which allows the user to customize the coupling to best serve their application. Considerations for elastomer selection include ability to dampen vibration, ability to handle misalignment, operational temperature range, speed of equipment, and chemical conditions.

Maintenance Requirements for Flexible Flange Couplings
Proper maintenance is essential to ensure the optimal performance and longevity of flexible flange couplings. Regular inspections and maintenance routines can help detect and prevent potential issues before they escalate into major problems. Here are the key maintenance requirements for flexible flange couplings:
- Visual Inspections: Regularly inspect the coupling for any signs of wear, damage, or misalignment. Look for cracks, tears, or deformations in the elastomeric elements and ensure that the flanges are securely fastened.
- Lubrication: Some flexible flange couplings may require periodic lubrication at the flange interface or other moving parts. Check the manufacturer’s guidelines for the recommended lubrication schedule and use the appropriate lubricant.
- Torque Checks: Verify that the flange bolts or screws are tightened to the specified torque. Loose fasteners can lead to misalignment and reduce the coupling’s performance.
- Alignment: Ensure that the connected shafts are correctly aligned. Misalignment can cause increased stress on the coupling and lead to premature failure. If misalignment is detected, it should be corrected promptly.
- Environmental Protection: In harsh environments, such as those with high humidity, chemicals, or abrasive particles, consider implementing protective measures to shield the coupling from potential damage.
- Inspections After Shock Loads: If the coupling is subjected to shock loads or excessive stress, perform thorough inspections to check for any deformation or damage that may have occurred.
- Replace Worn Elements: Over time, the elastomeric elements of the coupling may wear out. Replace these elements when they show signs of deterioration to maintain the coupling’s performance.
It is important to follow the manufacturer’s maintenance guidelines and recommendations specific to the particular flexible flange coupling model being used. Regular maintenance not only ensures the coupling’s optimal performance but also enhances the safety of the overall mechanical system.
How do Flexible Flange Couplings Ensure Efficient Torque Transmission and Minimal Backlash?
Flexible flange couplings are designed to efficiently transmit torque between two shafts while minimizing backlash, ensuring smooth and reliable power transmission in mechanical systems. Here’s how they achieve these goals:
1. Flexibility: The key feature of flexible flange couplings is their inherent flexibility. They are made of materials that can deform slightly under load, allowing them to absorb misalignments and angular displacements between the shafts. This flexibility helps in distributing the load evenly across the coupling and prevents concentrated stress points that can lead to backlash or premature failure.
2. Absorption of Misalignments: In real-world applications, it is challenging to achieve perfect alignment between two shafts due to manufacturing tolerances, thermal expansion, or dynamic forces. Flexible flange couplings can accommodate both angular and axial misalignments, compensating for these alignment errors. By allowing the shafts to find their natural positions within the coupling, they reduce stress on the components and ensure efficient torque transmission.
3. Resilient Materials: Flexible flange couplings are typically made of resilient materials such as high-quality elastomers or flexible metallic elements like stainless steel. These materials have excellent damping properties, which means they can absorb vibrations and shocks during operation. By reducing vibrations, the couplings contribute to smoother torque transmission and lower noise levels.
4. High Torque Capacity: Despite their flexibility, modern flexible flange couplings are engineered to handle high torque loads. The coupling’s design and material selection are optimized to maintain structural integrity and transmit torque efficiently even under heavy loads.
5. No Mechanical Play: Backlash refers to the rotational play or slack between the connected shafts. Flexible flange couplings minimize backlash by securely connecting the shafts without any mechanical play. The coupling’s flexibility allows it to maintain contact with the shafts continuously, ensuring precise torque transmission without any noticeable free movement.
6. Torsional Stiffness: Flexible flange couplings are designed with a balance between flexibility and torsional stiffness. While they can accommodate misalignments, they also provide sufficient torsional rigidity to transmit torque efficiently. This balance ensures that the coupling can dampen vibrations and misalignments while still maintaining reliable torque transmission.
7. Maintenance and Lubrication: Proper maintenance, including regular inspection and lubrication, is essential to ensure the longevity and optimal performance of flexible flange couplings. Adequate lubrication helps reduce friction and wear, further improving torque transmission efficiency.
Overall, flexible flange couplings are versatile components that play a crucial role in efficient power transmission and ensuring smooth operation in various mechanical systems. Their ability to handle misalignments, dampen vibrations, and transmit torque without backlash makes them an ideal choice for critical applications in industries such as manufacturing, power generation, marine, and many others.
Torque and Speed Limits for Flexible Flange Coupling Designs
Flexible flange couplings come in various designs, each with its specific torque and speed limits. These limits are essential considerations when selecting the appropriate coupling for a particular application. The following factors influence the torque and speed limits:
- Coupling Material: The material used in the flexible flange coupling plays a crucial role in determining its torque and speed limits. Couplings made from materials with higher tensile and shear strength, such as steel or alloy, can handle higher torque loads and operate at higher speeds compared to those made from elastomeric materials.
- Elastomer Hardness: For flexible flange couplings with elastomeric elements, the hardness of the elastomer affects the torque and speed limits. Softer elastomers generally offer greater flexibility and misalignment accommodation but may have lower torque and speed ratings. Harder elastomers can handle higher torque and speed but provide less flexibility.
- Coupling Size: The physical size of the coupling also impacts its torque and speed limits. Larger couplings, with more substantial and thicker flanges and elastomer elements, can generally handle higher torque loads and operate at higher speeds.
- Design and Construction: The design and construction of the flexible flange coupling influence its overall strength and performance. Couplings with optimized designs, precision machining, and robust construction can withstand higher torque and speed levels.
- Application Requirements: The specific requirements of the application, such as the level of misalignment, the magnitude of torque loads, and the desired rotational speed, will determine the suitable flexible flange coupling with the appropriate torque and speed limits.
Manufacturers of flexible flange couplings provide detailed specifications, including torque and speed ratings, for each coupling design they offer. It is crucial to adhere to these specified limits to ensure the safe and reliable operation of the coupling in the intended application.
During the selection process, engineers and designers should carefully match the torque and speed requirements of the application with the capabilities of the chosen flexible flange coupling. This ensures that the coupling operates optimally and provides long-lasting and efficient power transmission in the mechanical system.
