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 Maintenance Requirements for Bellows Couplings to Ensure Reliable Performance?

Proper maintenance of bellows couplings is essential to ensure their reliable performance and extend their service life. Here are some maintenance requirements and practices for bellows couplings:

• Regular Inspection: Perform routine inspections of the bellows coupling to check for any signs of wear, damage, or misalignment. Look for cracks, tears, or deformation in the bellows element, as these issues can lead to coupling failure.
• Lubrication: In most cases, bellows couplings do not require lubrication. However, some specific applications or coupling designs may benefit from periodic lubrication of the shafts. Always follow the manufacturer’s guidelines regarding lubrication, as using the wrong type of lubricant can damage the coupling.
• Keep the Coupling Clean: Ensure that the bellows coupling and its surroundings are clean and free from debris. Dirt, dust, and foreign particles can accelerate wear and reduce the coupling’s performance.
• Avoid Overloading: Do not exceed the maximum torque and speed limits specified by the manufacturer. Overloading the coupling can cause premature failure and compromise the system’s performance.
• Address Misalignment and Shaft Movement: If misalignment or shaft movement occurs during operation, identify and correct the root cause promptly. Excessive misalignment or axial motion can put extra stress on the bellows and lead to premature failure.
• Inspect Fasteners: Check and tighten the fasteners, such as set screws or clamping screws, that secure the coupling to the shafts. Loose fasteners can cause the coupling to slip or shift, affecting its performance.
• Replace Damaged Couplings: If any signs of damage or wear are detected during inspection, replace the bellows coupling with a new one. Continuing to use a damaged coupling can result in catastrophic failure and potential damage to connected machinery.
• Follow Manufacturer’s Guidelines: Always follow the maintenance instructions provided by the coupling manufacturer. They may have specific recommendations for inspection intervals, cleaning methods, and other maintenance practices.

By following these maintenance practices, you can ensure that your bellows couplings remain in good condition and deliver reliable performance throughout their operational life. Regular inspections and proactive maintenance help identify potential issues early, allowing you to take corrective actions before they escalate into more significant problems.

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.

Can you explain the Working Principle of a Bellows Coupling and its Advantages in Various Industries?

A bellows coupling is a type of flexible coupling that consists of a bellows element, which is a thin-walled, corrugated metal tube. The working principle of a bellows coupling involves utilizing the elasticity and flexibility of the bellows to transmit torque while accommodating misalignments between the driving and driven shafts.

When torque is applied to the coupling, the bellows element flexes and expands or contracts based on the rotational motion of the shafts. This flexing capability allows the coupling to compensate for angular, axial, and parallel misalignments, providing a degree of freedom for both shafts without inducing excessive stress or load on the connected machinery.

Advantages of Bellows Couplings in Various Industries:

• High Misalignment Compensation: Bellows couplings can accommodate higher misalignments compared to other coupling types, making them ideal for applications where precise alignment is challenging or where shafts may experience dynamic misalignments during operation.
• Torsional Stiffness: Some bellows coupling designs offer high torsional stiffness, ensuring efficient torque transmission and maintaining positional accuracy in motion control systems.
• Backlash-Free: Bellows couplings are typically backlash-free, meaning they have minimal play or clearance between the bellows and the coupling hubs. This characteristic is crucial in precision systems where any degree of backlash can lead to positioning errors.
• Vibration Dampening: The flexible nature of the bellows element helps dampen vibrations and shocks, reducing wear and tear on connected components and improving overall system reliability.
• Electrical Isolation: Some bellows coupling designs offer electrical isolation between the shafts, preventing the transmission of electrical currents and providing protection to sensitive electronic equipment.
• Compact Size: Bellows couplings are available in compact designs, making them suitable for applications with limited space, such as robotics, aerospace, and medical devices.
• Temperature and Corrosion Resistance: Depending on the material used, bellows couplings can exhibit excellent resistance to high temperatures and corrosion, making them suitable for harsh environments in industries like oil and gas, chemical, and marine.

Bellows couplings find applications in a wide range of industries, including robotics, automation, aerospace, medical equipment, semiconductor manufacturing, precision machinery, and more. Their ability to handle misalignments, provide backlash-free motion, and offer excellent torsional stiffness makes them a versatile and reliable choice for critical motion control systems.
