Product Description
Introduction
- Oldham couplings are a 3 piece design comprised of 2 aluminum hubs press fit CHINAMFG a center disk. Torque transmission is accomplished by mating the slots on the center disk to the drive tenons on the hubs. During operation the center disk slides on the tenons of each hub (which are orientated 90 apart) to transmit torque.
- While the couplings accommodate a small amount of angular and axial misalignment, they are especially useful in applications with parallel misalignment.
- We offers oldham couplings in set screw or clamp styles with bores ranging from 4mm to 35mm. Inch and metric hubs (set screw, clamp style, keyed, or keyless) are interchangeable and can be combined into a single coupling as long as they have the same outside diameter. Oldham coupling hubs are standard in black anodized aluminum for improved lubricity, increased life, and low inertia. Hubs are also available in stainless steel CHINAMFG request for increased corrosion resistance.
Application
- Ideal for many light duty industrial and motion control applications, oldham couplings have the ability to protect more expensive machinery components.
- For example the oldham coupling acts as a torque limiter during overload. When the disk fails, it breaks cleanly and does not allow any transmission of power.
- Oldham couplings also have the advantage of electrical isolation due to the non-conductive nature of the center disk.
- This prevents electrical currents from being passed to delicate instruments which can cause inaccurate data readings or damage.

How does a flexible coupling contribute to the longevity of connected equipment?
A flexible coupling plays a crucial role in enhancing the longevity of connected equipment in various ways. It acts as a mechanical interface between two shafts, connecting them while accommodating misalignment, dampening vibrations, and transmitting torque. Here’s how a flexible coupling contributes to the longevity of connected equipment:
- Misalignment Compensation: One of the primary functions of a flexible coupling is to compensate for both angular and parallel misalignment between two shafts. Misalignment can occur due to various factors, including thermal expansion, assembly errors, or settling of foundation, which can exert excessive stress on the connected equipment. By allowing misalignment, the flexible coupling reduces the stress transmitted to the shafts and connected components, preventing premature wear and failure.
- Shock and Vibration Dampening: Flexible couplings are designed to absorb shocks and dampen vibrations that occur during operation. Vibrations and shocks can be detrimental to connected equipment, leading to fatigue, wear, and premature failure of components. The coupling acts as a buffer, reducing the impact of vibrations and protecting the equipment from potential damage.
- Reduced Stress Concentration: A rigid coupling can create stress concentration points on the shafts, leading to fatigue and cracking over time. Flexible couplings distribute the load more evenly along the shafts, reducing stress concentration and minimizing the risk of failure.
- Transmitting Torque Smoothly: Flexible couplings transmit torque from one shaft to another smoothly, without introducing sudden torque spikes or shocks. This even torque transfer prevents sudden loading on connected equipment, minimizing the risk of damage or accelerated wear on gears, bearings, and other components.
- Controlling Torsional Vibrations: In systems where torsional vibrations are a concern, certain types of flexible couplings are designed to address this issue. These couplings help control torsional vibrations, which can be damaging to the equipment and cause premature failure.
- Thermal Expansion Compensation: When the equipment operates at different temperatures, thermal expansion can lead to misalignment between the shafts. A flexible coupling can accommodate the thermal expansion, ensuring that the connected equipment remains aligned and preventing stress on the components.
- Isolation from External Forces: External forces like impact loads or shaft disturbances can affect the connected equipment. A flexible coupling isolates the equipment from these external forces, protecting it from potential damage.
By providing these essential functions, a flexible coupling helps extend the lifespan of connected equipment by reducing wear and tear, preventing premature failures, and ensuring smooth, reliable operation. The longevity of the connected equipment ultimately results in reduced maintenance costs and increased productivity.
Can flexible couplings be used in pumps, compressors, and fans?
Yes, flexible couplings can be used in pumps, compressors, and fans, and they are commonly employed in these types of rotating machinery. Flexible couplings offer several advantages that make them suitable for such applications:
- Misalignment Compensation: Pumps, compressors, and fans often experience misalignments due to various factors, such as thermal expansion, foundation settling, or component wear. Flexible couplings can accommodate angular, parallel, and axial misalignments, helping to maintain proper alignment between the driving and driven components.
- Vibration Damping: Flexible couplings help dampen vibrations in rotating machinery, which is essential for smooth operation and reduced wear on components. In pumps, compressors, and fans, vibration control is crucial to prevent premature failure and maintain reliable performance.
- Shock Load Absorption: These rotating machines may encounter shock loads during startup or shutdown, especially in reciprocating equipment like reciprocating pumps or compressors. Flexible couplings can absorb and mitigate the impact of such loads, protecting the connected equipment from damage.
- Reduced Maintenance: Flexible couplings with elastomeric elements or other self-lubricating features require minimal maintenance, leading to cost savings and reduced downtime in pumps, compressors, and fans.
- Energy Efficiency: Certain flexible coupling designs, such as beam couplings or certain elastomeric couplings, have low mass and inertia. This characteristic helps improve the energy efficiency of rotating machinery, which is particularly beneficial in large-scale pumps, compressors, and fans used in industrial applications.
- Adaptability: Pumps, compressors, and fans often have varying operating conditions and load profiles. Flexible couplings are adaptable to different operating environments, making them suitable for diverse applications.
In summary, flexible couplings offer several performance-enhancing features that make them well-suited for use in pumps, compressors, and fans. Their ability to accommodate misalignment, dampen vibrations, absorb shocks, and reduce maintenance requirements contributes to improved reliability, efficiency, and longevity of the connected rotating machinery.
Can you explain the different types of flexible coupling designs available?
There are several types of flexible coupling designs available, each with its unique construction and characteristics. These designs are tailored to meet specific application requirements and address different types of misalignment and torque transmission needs. Here are some of the most common types of flexible couplings:
- Jaw Couplings: Jaw couplings consist of two hubs with curved jaws and an elastomer spider placed between them. The spider acts as a flexible element and can compensate for angular and parallel misalignment. Jaw couplings are widely used in various industrial applications due to their simple design and effectiveness in handling misalignment and vibration damping.
- Disc Couplings: Disc couplings use thin metallic discs with a series of alternating slits and flanges to connect the shafts. The disc coupling design allows for excellent misalignment compensation, including angular, parallel, and axial misalignment. Disc couplings are known for their high torsional stiffness and precise torque transmission capabilities.
- Gear Couplings: Gear couplings consist of toothed hubs connected by an external sleeve with gear teeth. They are well-suited for applications with high torque and moderate misalignment. Gear couplings offer good misalignment compensation and high torque capacity, making them popular in heavy-duty industrial applications.
- Beam Couplings: Beam couplings use a single piece of flexible material, often a metal beam, to connect the shafts. The material’s flexibility allows for angular and axial misalignment compensation. Beam couplings are compact, lightweight, and provide low inertia, making them suitable for applications with high-speed requirements.
- Bellows Couplings: Bellows couplings consist of a bellows-like flexible structure that connects the two hubs. They can compensate for angular, parallel, and axial misalignment. Bellows couplings are known for their high torsional stiffness and ability to maintain constant velocity transmission.
- Oldham Couplings: Oldham couplings use three discs, with the middle one having a perpendicular slot. This design allows for angular misalignment compensation while transmitting torque between the hubs. Oldham couplings are often used when electrical isolation between shafts is required.
Each flexible coupling design has its strengths and limitations, and the choice depends on factors such as the application’s torque requirements, misalignment conditions, operating environment, and speed. Proper selection of the coupling type ensures optimal performance, efficiency, and reliability in various mechanical systems and rotating machinery.
