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

Are there Specific Temperature and Torque Limits for Different Bellows Coupling Materials?

Bellows couplings are available in a variety of materials, each with its own temperature and torque limits. The choice of material depends on the specific application requirements, including environmental conditions, operating temperatures, and torque demands. Here are some commonly used bellows coupling materials and their respective temperature and torque limits:

1. Stainless Steel: Stainless steel bellows couplings are widely used due to their excellent corrosion resistance and high strength. They can operate in a wide temperature range, typically from -40°C to 400°C (-40°F to 752°F). The torque limits for stainless steel bellows couplings vary based on their size and construction but can range from a few Nm to several hundred Nm.
2. Aluminum: Aluminum bellows couplings are lightweight and offer good corrosion resistance. They are suitable for applications with lower torque requirements. The temperature limits for aluminum couplings range from -30°C to 150°C (-22°F to 302°F), and the torque limits generally range from a few Nm to around 50 Nm.
3. Brass: Brass bellows couplings are known for their electrical conductivity and are often used in applications where electrical isolation is required. They have temperature limits similar to aluminum couplings, ranging from -30°C to 150°C (-22°F to 302°F), and torque limits comparable to aluminum couplings.
4. Titanium: Titanium bellows couplings offer exceptional strength and corrosion resistance, making them suitable for demanding applications. They can operate in a temperature range of -50°C to 300°C (-58°F to 572°F), and their torque limits range from a few Nm to several hundred Nm.
5. Inconel: Inconel is a high-temperature alloy that provides excellent performance in extreme heat and corrosive environments. Inconel bellows couplings can operate in temperatures from -60°C to 600°C (-76°F to 1112°F) and have high torque capacities, ranging from a few Nm to over a thousand Nm.
6. Plastics: Certain plastic materials, such as PEEK (Polyether Ether Ketone), are used for bellows couplings in specialized applications. Plastic couplings offer lower torque capacities compared to metal couplings but can operate in a temperature range of -30°C to 250°C (-22°F to 482°F).

It is essential to consult the manufacturer’s specifications and guidelines to select the appropriate bellows coupling material for your specific application. Choosing the right material ensures that the coupling can withstand the operating conditions and delivers reliable performance throughout its service life.

Are Bellows Couplings Suitable for Use in Corrosive or Harsh Environments?

Bellows couplings can be suitable for use in corrosive or harsh environments, depending on the material they are made from and their design. The choice of material is a crucial factor in determining the coupling’s resistance to corrosion and its ability to withstand harsh conditions.

Common materials used in manufacturing bellows couplings that offer good resistance to corrosion include stainless steel and other high-grade alloys. Stainless steel is known for its excellent corrosion resistance, making it well-suited for applications in harsh or corrosive environments.

In some cases, bellows couplings can be coated or treated with specialized coatings to further enhance their resistance to corrosion. These coatings can provide an additional layer of protection, allowing the coupling to perform effectively even in highly aggressive surroundings.

It’s essential to consider the specific environmental conditions and the type of corrosive agents present when selecting a bellows coupling for use in such environments. Proper material selection and the appropriate protective measures can ensure the longevity and reliability of the coupling under challenging conditions.

Additionally, it is essential to consult with coupling manufacturers or experts to identify the most suitable coupling material and design for the particular corrosive or harsh environment in question. Customized bellows couplings may be available to meet specific requirements, providing further versatility in addressing the challenges posed by corrosive or harsh conditions.

How do you Select the Right Bellows Coupling for Specific Motion Control Systems?

Selecting the right bellows coupling for a motion control system involves considering several key factors to ensure optimal performance and reliability. Here are the steps to help you make an informed decision:

1. Application Requirements: Understand the specific requirements of your motion control system. Consider factors such as torque capacity, speed, angular misalignment, axial motion, and environmental conditions.
2. Type of Bellows Coupling: Determine the type of bellows coupling that best suits your application. Choose from single bellows, double bellows, flexible beam with bellows, torsionally rigid, miniature, or high-temperature bellows coupling, depending on your needs.
3. Torsional Stiffness: If your application requires high torsional stiffness to maintain precise motion control, consider bellows couplings with torsionally rigid designs.
4. Misalignment Compensation: Evaluate the amount of misalignment your system may encounter and choose a bellows coupling with the appropriate misalignment compensation capabilities.
5. Torque and Speed Ratings: Check the torque and speed ratings of the coupling to ensure they meet or exceed the requirements of your motion control system.
6. Space Constraints: Consider the available space for the coupling. For applications with limited space, miniature or compact bellows couplings may be suitable.
7. Environmental Conditions: If your application involves extreme temperatures or corrosive environments, opt for a high-temperature or corrosion-resistant bellows coupling material.
8. Customization: Some applications may require customized solutions. In such cases, consult with coupling manufacturers to explore the possibility of tailored designs.
9. Consult with Experts: When in doubt, seek advice from coupling manufacturers or engineering experts who can offer valuable insights and recommendations based on your specific application needs.

By carefully considering these factors, you can select the right bellows coupling that aligns with your motion control system’s requirements and ensures smooth and efficient power transmission. Additionally, choosing high-quality and reputable coupling suppliers will contribute to the overall success and reliability of your motion control application.
