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.

Feature

  • High absorption capacity of radial misaligment
  • They do not produce kinematic errors in transmission
  • Elimination of loads on shaft
  • Mechanical protection against excessive torque
  • Replaceable disc

    Use of Jaw Couplings in Corrosive or Harsh Environments

    Jaw couplings can be used in certain corrosive or harsh environments, but the choice of materials and design should be carefully considered to ensure the coupling’s performance and longevity. Here’s how jaw couplings can be utilized in such environments:

    • Material Selection: For corrosive environments, it is essential to choose materials that can withstand the specific chemicals or substances present. Stainless steel or other corrosion-resistant alloys are commonly used in jaw couplings to ensure resistance to rust and corrosion. These materials protect the coupling from degradation caused by exposure to corrosive elements.
    • Sealing Mechanism: In harsh environments where contaminants or particles may be present, proper sealing becomes crucial. Many jaw couplings have various sealing options to prevent foreign materials from entering the coupling and affecting its performance. Seals can help keep the coupling’s interior clean and protect it from damage due to harsh substances.
    • Environmental Protection: In applications where the coupling is exposed to harsh elements, it might be beneficial to utilize protective covers or guards. These can shield the coupling from direct contact with abrasive materials or chemicals, further extending its lifespan in challenging conditions.
    • Regular Maintenance: In corrosive or harsh environments, proper and regular maintenance is crucial. Cleaning and inspecting the coupling periodically can help identify any signs of wear or damage and allow for timely replacements or repairs, minimizing the risk of failure in service.

    While jaw couplings can be used in certain corrosive or harsh environments, it is essential to assess the specific conditions and requirements of the application carefully. In some instances, alternative coupling types or additional protective measures may be more suitable to ensure optimal performance and longevity. Consulting with coupling manufacturers or engineering experts can provide valuable insights in selecting the most appropriate coupling for a given environment.

    How does a jaw coupling deal with backlash and torsional stiffness?

    A jaw coupling addresses backlash and torsional stiffness through its unique design features and choice of materials. Backlash is the amount of free play or clearance between the coupling components, while torsional stiffness refers to the resistance of the coupling to torsional or twisting forces. Here’s how a jaw coupling deals with these aspects:

    • Backlash: Jaw couplings are designed to minimize backlash by ensuring a close fit between the elastomer spider and the jaws of the coupling hubs. The elastomer spider acts as a flexible intermediary that fills the space between the mating jaws, reducing any free play between them. This close fit reduces backlash and provides a more precise and responsive power transmission, especially in reversing or intermittent motion applications.
    • Torsional Stiffness: Torsional stiffness is achieved in jaw couplings by using materials that provide a balance between flexibility and rigidity. The elastomer spider in the coupling offers some flexibility, allowing it to absorb vibrations and dampen shocks. However, to ensure adequate torsional stiffness, the coupling hubs are usually made from sturdier materials like steel or aluminum. The choice of elastomer material and its geometry also influences the torsional stiffness of the coupling. Some applications may require coupling designs with higher torsional stiffness to maintain the accuracy and stability of the system, while others may benefit from more flexible couplings that can accommodate misalignments and shock loads. Overall, the combination of the elastomer’s flexibility and the coupling hub’s rigidity results in a coupling with a balanced torsional stiffness that can meet the specific needs of the application.

    In summary, a jaw coupling minimizes backlash by providing a close fit between the coupling components, and it achieves torsional stiffness by using a combination of flexible elastomer materials and rigid coupling hubs. These design considerations make jaw couplings suitable for a wide range of applications that require reliable power transmission, precise motion control, and the ability to handle misalignments and shocks.

    Comparing Jaw Couplings to Other Types of Couplings in Performance

    Jaw couplings offer certain advantages and disadvantages compared to other types of couplings, and their performance characteristics vary based on the specific application requirements. Here’s a comparison of jaw couplings with some commonly used coupling types:

    • Jaw Couplings vs. Gear Couplings: Jaw couplings are more economical and easier to install than gear couplings. They can handle misalignment to some extent, but gear couplings are better suited for high torque and high misalignment applications.
    • Jaw Couplings vs. Disc Couplings: Both jaw couplings and disc couplings provide some level of misalignment compensation, but disc couplings offer higher torque capacity and better torsional stiffness. Jaw couplings are generally more cost-effective for low to moderate torque applications.
    • Jaw Couplings vs. Oldham Couplings: Jaw couplings are torsionally stiffer than Oldham couplings, which means they provide more accurate torque transmission. However, Oldham couplings can accommodate higher misalignment and have no moving parts, making them suitable for some low-speed applications.
    • Jaw Couplings vs. Flexible Beam Couplings: Beam couplings are more flexible than jaw couplings and can handle higher misalignment. However, jaw couplings have a higher torque capacity and can dampen vibration better in certain conditions.

    Ultimately, the choice of coupling depends on the specific needs of the application, including factors like torque requirements, misalignment, speed, and cost considerations. It’s essential to carefully evaluate the performance characteristics of different coupling types and select the one that best suits the demands of the mechanical system to ensure reliable and efficient power transmission.
