Product Description

OEM Precision CNC Machining Clamping Type Flexible Disc Coupling Jaw Coupling Oldham Coupling for Metallurgy/Mining/Power/Pump

Product Description

Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used
as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.

Couplings can be divided into rigid couplings and flexible couplings. Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.

Product Description

OEM Precision CNC Machining Clamping Type Flexible Disc Coupling Jaw Coupling Oldham Coupling for Metallurgy/Mining/Power/Pump

Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used
as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.

Couplings can be divided into rigid couplings and flexible couplings. Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.

Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. 

Our leading mainly including universal couplings, drum gear couplings, elastic couplings etc.
Main production equipments:
Large lathe, surface grinder, milling machine, spline milling machine, horizontal broaching machine, gear hobbing machine, shaper, slotting machine, bench drilling machine, radial drilling machine, boring machine, band sawing machine, horizontal lathe, end milling machine, crankshaft grinder, CNC milling machine, etc.

Coupling performance
1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CHINAMFG requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.

Inspection equipment:
Dynamic balance tester, high-speed intelligent carbon and sulfur analyzer, Blochon optical hardness tester, Leeb hardness tester, magnetic yoke flaw detector etc.
  
It is widely used in metallurgical steel rolling, wind power, hydropower, mining, engineering machinery, petrochemical, lifting, paper making, rubber, rail transit, shipbuilding and marine engineering and other industries.

How to select the appropriate coupling type
The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

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.

How to Identify Signs of Wear or Damage in an Oldham Coupling?

Regular inspection of Oldham couplings is essential to ensure their proper functioning and prevent unexpected failures. Here are some signs of wear or damage to look for during the inspection:

1. Visible Cracks or Deformation: Check the center disc and the hubs for any visible cracks, tears, or deformation. These can be indicators of excessive stress or misalignment.

2. Abnormal Vibrations: Excessive vibrations during operation may suggest that the coupling is not functioning correctly. It could be due to wear in the center disc or improper installation.

3. Unusual Noise: Grinding, clicking, or banging noises during equipment operation may indicate that the Oldham coupling is experiencing excessive backlash or misalignment.

4. Increased Backlash: If there is noticeable play or free movement between the coupling components, it may be a sign of wear in the center disc or worn hubs.

5. Reduced Performance: A decrease in the performance of the machinery or unexpected issues with power transmission could be indicative of coupling problems.

6. Abnormal Heating: If the coupling becomes unusually hot during operation, it may suggest friction or misalignment issues.

7. Excessive Wear on Center Disc: Inspect the center disc for signs of wear, such as grooves, uneven surfaces, or material loss. This may occur over time due to the repeated flexing of the disc.

8. Lubrication Issues: Improper or inadequate lubrication can lead to increased friction and wear in the coupling components.

If any of these signs are observed during the inspection, it is essential to address the issue promptly. Depending on the severity of the wear or damage, the Oldham coupling may require replacement or repair. Regular maintenance and proper lubrication can help extend the life of the coupling and prevent unexpected failures, ensuring smooth and reliable operation in the machinery or equipment.

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.

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.

Programming With Couplings

A coupling is a mechanical device that connects two shafts together and transmits power. Its purpose is to join rotating equipment and allows some degree of end-movement or misalignment. There are many different types of couplings. It’s important to choose the right one for your application.
gearbox

Mechanical connection between two shafts

There are many ways to achieve mechanical connection between two shafts, including the use of a coupling. One common type is the beam coupling, which is also known as a helical coupling. It is used for transmission of torque between two shafts. This type of connection accommodates axial, parallel and angular misalignments.
The hubs and shafts of a worm gear are connected together by a coupling. This mechanical connection allows one shaft to turn another without causing a mechanical failure. This type of coupling is made from sliding or rubbing parts to transfer torque. However, the coupling is not designed to withstand jerks, so it isn’t suitable for high-speed applications.
The use of a coupling is common in machinery and equipment. It helps transmit power from one drive shaft to the other, while adding mechanical flexibility. It is also useful for reducing the impact and vibration caused by misalignment. It also protects the drive shaft components from wear and tear.
A double-hook coupling can be used to provide a uniform angular velocity at the driven shaft. Another example is a double-jointed coupling. A double-jointed coupling can be used to connect shafts that are not directly intersecting. The double-jointed yoke can be used for the same purpose.
A shaft coupling is a device that maintains a strong mechanical connection between two shafts. It transfers motion from one shaft to another, at all loads and misalignments. Unlike a conventional linkage, a shaft coupling isn’t designed to allow relative motion between the two shafts. Couplings often serve several purposes in a machine, but their primary use is torque and power transmission.

Functions that control the flow of another function

One of the simplest programming constructs is a function that controls the flow of another function. A function can take an argument and return a different value, but it must be ready to return before it can pass that value to another function. To do this, you can use the goto statement and the if statement. Another way to control flow is to use a conditional statement.
gearbox

Criteria for selecting a coupling

There are several important factors to consider when choosing the right coupling. One of the most important factors is coupling stiffness, which depends on the material used and the shape. The stiffness of a coupling determines its ability to resist elastic deformation. A stiff coupling is desirable for certain types of applications, but it’s undesirable for others. Stiffness can reduce the performance of a system if there’s too much inertia. To avoid this, ensure that the coupling you choose is within the recommended limits.
The size of a coupling is also important. Different coupling types can accommodate different shaft sizes and shapes. Some couplings have special features, such as braking and shear pin protection. When choosing a coupling, you should also consider the type of driven equipment. If you need to connect a high-torque motor, for example, you’ll want to choose a gear coupling. Likewise, a high-speed machine may require a disc coupling.
Another factor to consider when selecting a coupling is the torque rating. Despite its importance, it’s often underestimated. The torque rating is defined as the torque of the coupling divided by its OD. In some cases, torque may fluctuate during a cycle, requiring a coupling with a higher torque rating.
Torsionally flexible couplings are also important to consider. Their design should be able to withstand the torque required during operation, as well as the required speed. The coupling should also have a high degree of torsional stiffness, as well as damping. Furthermore, a damping coupling can reduce the energy wasted through vibration.
The sizing of a coupling is also determined by the torque. Many engineers use torque to select the correct coupling size, but they also take into consideration torsional flexibility and torsional stiffness. For example, a shaft may be able to handle large torque without damaging the coupling, while a disk may be unable to handle large amounts of torque.
Besides torque, another important consideration in coupling selection is the cost. While a coupling may be cheaper, it may be less reliable or easier to maintain. Couplings that are difficult to service may not last as long. They may also require frequent maintenance. If that’s the case, consider purchasing a coupling with a low service factor.
There are many different types of couplings. Some require additional lubrication throughout their lifetime, while others are 100% lubrication-free. An example of a 100% lubrication-free coupling is the RBI flexible coupling from CZPT. This type of coupling can significantly reduce your total cost of ownership.
In addition to the above-mentioned benefits, elastomeric couplings are low-cost and need little maintenance. While they are often cheaper than metallic couplings, they also have excellent shock absorption and vibration dampening properties. However, they are susceptible to high temperatures. Also, they are difficult to balance as an assembly, and have limited overload torque capacity.
