China Custom Zs Factory Price High Precision Oldham Flexible Couplings for Automation Machinery oldham coupling

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

    What are the Potential Limitations or Drawbacks of Using an Oldham Coupling?

    While Oldham couplings offer numerous advantages, they also have some limitations and drawbacks that should be considered when selecting a coupling for a specific application:

    1. Limited Misalignment Capacity: Oldham couplings can only accommodate small amounts of angular and axial misalignment between the shafts. They are not suitable for applications with high levels of misalignment as excessive misalignment can lead to premature wear and failure of the center disc.

    2. Speed Limitations: Oldham couplings are generally not recommended for high-speed applications. The flexible center disc has a maximum speed limit, and exceeding this limit can cause the disc to fatigue and fail over time.

    3. Temperature Sensitivity: The performance of Oldham couplings can be affected by temperature fluctuations. Extreme temperatures can impact the flexibility and integrity of the center disc material, leading to reduced coupling performance.

    4. Backlash in High-Precision Systems: While Oldham couplings minimize backlash compared to some other couplings, they may still have some inherent clearance between the hubs and the center disc, leading to a slight amount of backlash. In ultra-high-precision systems, this slight backlash may be a concern.

    5. Material Compatibility: The material used for the center disc must be chosen carefully to ensure compatibility with the specific application’s environment and the media being conveyed. Some aggressive chemicals or harsh environments may degrade the material over time.

    6. Maintenance: Oldham couplings require periodic inspection and maintenance to ensure proper functioning. The center disc may wear out over time and need replacement, especially in applications with high torque or frequent start-stop cycles.

    Despite these limitations, Oldham couplings remain a popular choice in many applications due to their vibration reduction, backlash minimization, and moderate misalignment compensation capabilities. However, it is essential to carefully assess the specific requirements of the application and consider the potential drawbacks before selecting an Oldham coupling.

    Differences Between Oldham Couplings and Other Types of Flexible Couplings

    Oldham couplings are a type of flexible coupling used in mechanical systems to transmit torque between two shafts. Here are some key differences between Oldham couplings and other types of flexible couplings:

    • Mechanism of Torque Transmission: Oldham couplings use a sliding motion between the center disc and the hubs to transmit torque. The center disc has slots that engage with pins on the hubs, allowing for torque transmission while accommodating misalignment. In contrast, other flexible couplings, such as jaw couplings or beam couplings, typically use elastic materials or flexible elements like rubber or springs to transmit torque.
    • Misalignment Compensation: Oldham couplings are specifically designed to handle angular misalignment between shafts. They can accommodate parallel misalignment to a limited extent but are not well-suited for axial misalignment. Other flexible couplings like beam couplings or bellows couplings may offer more comprehensive misalignment compensation, including axial misalignment.
    • Backlash: Oldham couplings have a small amount of backlash due to the clearance between the center disc and the hubs. This backlash can be beneficial in some applications to reduce shock loads and vibrations. However, other flexible couplings like beam couplings or jaw couplings may have minimal or zero backlash.
    • Construction and Materials: Oldham couplings are typically made of materials like aluminum for the hubs and center disc, and acetal or other plastics for the center disc’s sliding parts. Other flexible couplings come in various materials, including aluminum, stainless steel, elastomers, and composite materials, depending on the application’s requirements.
    • Operating Speed: Oldham couplings are suitable for moderate to high rotational speeds, but their speed limitations depend on the material and design. Some other flexible couplings, such as bellows couplings, can handle even higher speeds due to their construction.
    • Applications: Oldham couplings are commonly used in applications that require moderate torque transmission and angular misalignment compensation, such as pumps, packaging machines, and automation equipment. Other flexible couplings are used in a wide range of applications, including motion control systems, robotics, aerospace, and automotive industries, where specific coupling characteristics are needed.

    Choosing the right flexible coupling depends on the specific requirements of the application, including torque, misalignment, speed, space constraints, and environmental conditions. Engineers and designers should carefully consider these factors to select the most appropriate coupling for their mechanical system.

    How an Oldham Coupling Accommodates Misalignment Between Shafts

    An Oldham coupling accommodates misalignment between shafts through its unique design, which consists of three main components:

    1. Two Hubs: Each hub is attached to the shaft of the connected equipment. The hubs have a series of slots around their circumference.
    2. Middle Block: The middle block fits between the two hubs and has perpendicular slots on its inner diameter. It connects the two hubs while allowing relative movement between them.

    When the shafts experience angular or axial misalignment, the middle block slides within the slots of both hubs. The perpendicular slots on the middle block engage with the slots on the hubs, creating a parallelogram linkage.

    This parallelogram linkage allows the Oldham coupling to compensate for angular misalignment by enabling the hubs to rotate independently about their own axes. The sliding action of the middle block accommodates axial misalignment by allowing the hubs to move slightly closer or farther apart.

    The use of sliding contact instead of direct physical contact between the hubs minimizes friction, backlash, and wear, making the Oldham coupling an efficient and reliable method for transmitting torque while accommodating misalignment.

    Overall, the Oldham coupling’s ability to handle both angular and axial misalignment ensures smooth and precise torque transmission between shafts, reducing stress on connected equipment and extending the lifespan of mechanical components.

    Can an Oldham Coupling be Used in Precision Motion Control Applications?

    Yes, an Oldham coupling can be used in precision motion control applications. Oldham couplings are known for their ability to provide constant velocity transmission while accommodating misalignment. These couplings offer low backlash and minimal hysteresis, making them suitable for precision motion control systems.

    Precision motion control applications require accurate and repeatable motion, which can be achieved by using an Oldham coupling. The coupling’s design allows it to handle angular misalignment without introducing significant axial or radial forces. This feature helps maintain the accuracy and integrity of the motion control system.

    Oldham couplings are often used in applications such as robotics, CNC machines, optical equipment, and other systems where precise positioning and smooth motion are essential. Their ability to reduce vibration and minimize backlash is particularly beneficial in these applications, as it enhances the system’s overall performance and accuracy.

    When selecting an Oldham coupling for precision motion control, it is essential to consider factors such as the required torque capacity, speed, and shaft sizes. Additionally, regular maintenance and proper alignment are crucial to ensure the coupling’s optimal performance in precision applications.

    Transmission of Torque in Oldham Couplings

    An Oldham coupling is designed to transmit torque between two shafts that are misaligned but parallel to each other. It consists of three components: two hubs (also known as drive hubs) and a center disc. The hubs are connected to their respective shafts, while the center disc sits between them.

    The center disc of the Oldham coupling is characterized by slots or keyways on its opposite sides, which engage with the hubs. The slots allow the center disc to slide or float within the hubs while maintaining a constant angular velocity between the shafts.

    When torque is applied to the drive hub on one side, it induces a rotational force on the center disc. This rotational force is then transferred to the other drive hub, which results in torque transmission to the second shaft. The center disc acts as an intermediary between the two hubs, compensating for any axial or radial misalignment between the shafts.

    Regarding the question of different shaft diameters, the Oldham coupling can accommodate shafts with different diameters as long as the hub design allows for a secure connection. The keyways or slots in the center disc and hubs should be compatible with the shaft dimensions to ensure proper torque transmission and to prevent slippage or damage.

    It is essential to select the appropriate size and design of the Oldham coupling to match the shaft diameters and to ensure reliable torque transmission while accommodating any misalignment between the shafts.

    Can an Oldham Coupling Reduce Vibration and Backlash in Mechanical Systems?

    Yes, an Oldham coupling can help reduce vibration and minimize backlash in mechanical systems, making it a popular choice for applications that require precise and smooth power transmission.

    Vibration Reduction: Oldham couplings are designed with a three-piece construction, comprising two hubs and a center disc. The center disc, also known as the spacer, is made of a flexible material such as acetal or nylon. When torque is transmitted through the coupling, the center disc flexes, absorbing any misalignment between the shafts. This flexing action helps dampen vibration and reduces resonance in the system, leading to smoother operation and less mechanical stress on connected components.

    Backlash Minimization: Backlash is the amount of play or free movement between the mating parts of a mechanical system. In traditional couplings like gear couplings, there can be significant backlash due to the nature of the gear teeth. However, Oldham couplings have a unique design that allows them to transmit torque with minimal backlash. The center disc provides a small amount of clearance between the hubs, enabling smooth rotation without backlash. This characteristic is especially beneficial in applications that require precise motion control, such as robotics and CNC machines.

    Overall, the flexible and backlash-free nature of Oldham couplings makes them well-suited for applications where vibration reduction and precise motion control are essential. By reducing vibration and backlash, Oldham couplings contribute to the overall efficiency, accuracy, and reliability of the mechanical system they are employed in.

    oldham coupling

    Are there Industry Standards or Certifications for Oldham Couplings?

    Yes, there are industry standards and certifications that apply to Oldham couplings to ensure their quality, performance, and interchangeability. The most common standards and certifications related to couplings are set by organizations such as the American National Standards Institute (ANSI), the International Organization for Standardization (ISO), and the American Society of Mechanical Engineers (ASME). While these standards might not specifically focus on Oldham couplings, they often include requirements and guidelines that cover various types of flexible couplings, including Oldham couplings.

    For example, ANSI B11.20: Safety Requirements for Integrated Manufacturing Systems establishes safety requirements for the design, construction, installation, operation, and maintenance of integrated manufacturing systems. Although not specific to Oldham couplings, this standard may encompass certain aspects of coupling safety.

    Additionally, ISO 9001 certification is a widely recognized quality management system certification that many coupling manufacturers strive to achieve. This certification demonstrates a manufacturer’s commitment to producing high-quality products and adhering to rigorous quality control procedures.

    When selecting an Oldham coupling, it is essential to check if the manufacturer complies with relevant industry standards and has obtained certifications that demonstrate their commitment to product quality and safety. It is also crucial to consider the specific requirements of your application and whether the chosen coupling meets those needs.

    What is an Oldham Coupling and How Does It Function in Mechanical Systems?

    An Oldham coupling is a type of flexible coupling used in mechanical systems to transmit torque between two shafts that are misaligned. It consists of three main components: two hubs or discs and a middle block. The two hubs are connected to the respective shafts, and the middle block sits in between them.

    The key feature of the Oldham coupling is the middle block, which has slots on its opposite faces and is connected to the hubs using pins or keys. The slots in the middle block are oriented perpendicular to each other, allowing the middle block to move in a plane perpendicular to the axis of the shafts.

    When torque is applied to one shaft, it is transmitted to the middle block of the coupling. Due to the slots, the middle block can slide laterally as the shafts rotate, accommodating both angular and axial misalignments between the shafts. This sliding action helps to reduce the reaction forces and wear that would otherwise occur in rigid couplings when misalignment is present.

    Oldham couplings are known for their ability to provide constant velocity transmission even when misalignment exists. They do not have any backlash, which means there is minimal play between the coupling components during rotation. This feature makes them suitable for precision applications where accurate torque transmission and positioning are required.

    One of the main advantages of the Oldham coupling is that it effectively isolates the connected shafts from each other, which can help in reducing vibrations and noise. Additionally, it can compensate for parallel misalignment between the shafts, making it ideal for applications where parallel shafts need to be connected while allowing some degree of misalignment.

    Oldham couplings are commonly used in various industrial machinery and automation systems, including CNC machines, robotics, printing presses, and conveyor systems. They are particularly useful in applications where precise torque transmission, misalignment compensation, and low maintenance are essential.

    oldham coupling

    Can an Oldham Coupling be Used in Both Horizontal and Vertical Shaft Orientations?

    Yes, an Oldham coupling can be used in both horizontal and vertical shaft orientations. The design of the Oldham coupling allows it to accommodate misalignment between shafts in multiple directions, including axial, angular, and parallel misalignments.

    In horizontal shaft arrangements, the Oldham coupling can handle misalignment between two parallel shafts while transmitting torque smoothly and efficiently. It is commonly used in various power transmission applications where two shafts are relatively close together and require a reliable coupling to compensate for misalignment.

    In vertical shaft orientations, the Oldham coupling can handle axial misalignment, which is the misalignment between the rotational axes of the two shafts. This makes it suitable for applications where the connected shafts are not perfectly aligned due to gravitational forces or other factors.

    The Oldham coupling’s ability to accommodate misalignment in both horizontal and vertical shaft orientations makes it a versatile choice for a wide range of mechanical systems, including pumps, compressors, conveyor systems, and more. However, it is essential to ensure proper installation and maintenance to maximize the coupling’s performance and service life in any shaft orientation.

    oldham coupling

    Transmission of Torque in Oldham Couplings

    An Oldham coupling is designed to transmit torque between two shafts that are misaligned but parallel to each other. It consists of three components: two hubs (also known as drive hubs) and a center disc. The hubs are connected to their respective shafts, while the center disc sits between them.

    The center disc of the Oldham coupling is characterized by slots or keyways on its opposite sides, which engage with the hubs. The slots allow the center disc to slide or float within the hubs while maintaining a constant angular velocity between the shafts.

    When torque is applied to the drive hub on one side, it induces a rotational force on the center disc. This rotational force is then transferred to the other drive hub, which results in torque transmission to the second shaft. The center disc acts as an intermediary between the two hubs, compensating for any axial or radial misalignment between the shafts.

    Regarding the question of different shaft diameters, the Oldham coupling can accommodate shafts with different diameters as long as the hub design allows for a secure connection. The keyways or slots in the center disc and hubs should be compatible with the shaft dimensions to ensure proper torque transmission and to prevent slippage or damage.

    It is essential to select the appropriate size and design of the Oldham coupling to match the shaft diameters and to ensure reliable torque transmission while accommodating any misalignment between the shafts.

    Can an Oldham Coupling Reduce Vibration and Backlash in Mechanical Systems?

    Yes, an Oldham coupling can help reduce vibration and minimize backlash in mechanical systems, making it a popular choice for applications that require precise and smooth power transmission.

    Vibration Reduction: Oldham couplings are designed with a three-piece construction, comprising two hubs and a center disc. The center disc, also known as the spacer, is made of a flexible material such as acetal or nylon. When torque is transmitted through the coupling, the center disc flexes, absorbing any misalignment between the shafts. This flexing action helps dampen vibration and reduces resonance in the system, leading to smoother operation and less mechanical stress on connected components.

    Backlash Minimization: Backlash is the amount of play or free movement between the mating parts of a mechanical system. In traditional couplings like gear couplings, there can be significant backlash due to the nature of the gear teeth. However, Oldham couplings have a unique design that allows them to transmit torque with minimal backlash. The center disc provides a small amount of clearance between the hubs, enabling smooth rotation without backlash. This characteristic is especially beneficial in applications that require precise motion control, such as robotics and CNC machines.

    Overall, the flexible and backlash-free nature of Oldham couplings makes them well-suited for applications where vibration reduction and precise motion control are essential. By reducing vibration and backlash, Oldham couplings contribute to the overall efficiency, accuracy, and reliability of the mechanical system they are employed in.

    Can an Oldham Coupling be Used in Both Horizontal and Vertical Shaft Orientations?

    Yes, an Oldham coupling can be used in both horizontal and vertical shaft orientations. The design of the Oldham coupling allows it to accommodate misalignment between shafts in multiple directions, including axial, angular, and parallel misalignments.

    In horizontal shaft arrangements, the Oldham coupling can handle misalignment between two parallel shafts while transmitting torque smoothly and efficiently. It is commonly used in various power transmission applications where two shafts are relatively close together and require a reliable coupling to compensate for misalignment.

    In vertical shaft orientations, the Oldham coupling can handle axial misalignment, which is the misalignment between the rotational axes of the two shafts. This makes it suitable for applications where the connected shafts are not perfectly aligned due to gravitational forces or other factors.

    The Oldham coupling’s ability to accommodate misalignment in both horizontal and vertical shaft orientations makes it a versatile choice for a wide range of mechanical systems, including pumps, compressors, conveyor systems, and more. However, it is essential to ensure proper installation and maintenance to maximize the coupling’s performance and service life in any shaft orientation.

    Advantages of Using an Oldham Coupling Compared to Other Types of Couplings

    An Oldham coupling offers several advantages over other types of couplings, making it a preferred choice in certain applications:

    • Misalignment Compensation: The Oldham coupling can handle both angular and axial misalignments between shafts. It allows for up to a few degrees of misalignment while transmitting torque smoothly, reducing the risk of premature wear and failure caused by misalignment.
    • No Backlash: Unlike some other flexible couplings, the Oldham coupling has minimal backlash. This means there is little to no play or clearance between the coupling components during rotation, ensuring precise torque transmission and positioning in high-precision applications.
    • Vibration and Noise Damping: The sliding action of the middle block in the coupling helps to isolate the shafts from each other, reducing vibrations and noise during operation. This feature is beneficial in applications where vibration dampening is critical to equipment performance and longevity.
    • High Torque Transmission: Oldham couplings can handle relatively high torque transmission, making them suitable for applications with moderate to high torque requirements.
    • Low Maintenance: Due to its design, the Oldham coupling experiences minimal wear during operation, leading to lower maintenance requirements and longer service life.
    • Easy Installation: Oldham couplings are relatively easy to install and remove, simplifying maintenance and replacement procedures.
    • Electrically Insulating: Some Oldham couplings are available with non-conductive materials, providing electrical isolation between shafts, which is essential in certain applications.
    • Cost-Effective: Compared to other high-performance couplings, Oldham couplings are often more cost-effective, providing reliable performance without breaking the budget.

    Overall, the Oldham coupling is an excellent choice in applications where misalignment compensation, precision torque transmission, vibration dampening, and low maintenance are critical factors for successful operation. Its unique design and features make it suitable for various industrial and automation systems, contributing to smoother and more efficient mechanical power transmission.
