Especially within tough applications, drive components and processing machines are subject to extreme loads. FLUDEX couplings limit start and maximum torque within the drive train and serve as starting aids for the motor and as overload protection in the case of an incident. They also provide damping and separation of rotary oscillation, thereby reducing restoring forces to a minimum.

Fluid couplings operate according to the Föttinger principle. The coupling parts on the input and output side are not mechanically connected and are therefore wear-free. The torque is transmitted by the fluid movement in the coupling, accelerated by the radial blades. Our film illustrates the Föttinger principle as well as the operating principle of the FLUDEX coupling.

jaw coupling

Using Jaw Couplings in Precision Motion Control Systems

Jaw couplings are versatile mechanical couplings commonly used in various industrial applications for transmitting torque between two shafts. While they offer many benefits such as simplicity, cost-effectiveness, and ease of installation, they may not be the best choice for precision motion control systems that require extremely accurate and repeatable positioning. The following factors should be considered when using jaw couplings in precision motion control systems:

  • Backlash: Jaw couplings typically have some degree of backlash due to the clearance between the jaws and the spacers. This can introduce positional errors and limit the ability to achieve precise movements, especially in systems that require bidirectional positioning.
  • Angular and Parallel Misalignment: While jaw couplings can accommodate some degree of misalignment, precision motion control systems often require tight tolerances and minimal misalignment to achieve accurate positioning. In such cases, more rigid and flexible couplings, such as servo couplings or beam couplings, may be preferred.
  • Torsional Stiffness: In precision motion control, minimizing torsional wind-up and maintaining torsional stiffness is essential for precise and responsive movements. Jaw couplings may not provide the required level of torsional stiffness needed for high-performance motion control applications.
  • Resonance and Vibration: In precision motion systems, avoiding resonance and minimizing vibration is crucial for stability and accuracy. The damping characteristics of jaw couplings may not be sufficient to suppress vibrations and resonant frequencies, which can adversely affect performance.

While jaw couplings are widely used in general industrial applications, precision motion control systems often demand more specialized and precise coupling solutions. Some alternatives that are better suited for precision motion control applications include servo couplings, beam couplings, and disc couplings. These couplings offer higher torsional stiffness, lower backlash, and better overall performance for demanding motion control requirements.

When selecting a coupling for precision motion control, it is essential to consider the specific requirements of the application, including torque, speed, misalignment, and stiffness, to ensure the chosen coupling can meet the precision and performance demands of the system.

jaw coupling

Can jaw couplings be used in applications with high shock and impact loads?

Yes, jaw couplings can be used in applications with high shock and impact loads, but their suitability depends on the specific design and construction of the coupling as well as the magnitude and frequency of the shock and impact loads. Jaw couplings are known for their ability to handle certain levels of shock and vibration due to the presence of the elastomer spider, which acts as a damping element to absorb and dissipate vibrations. However, there are some important considerations to take into account when using jaw couplings in high shock and impact load applications:

  1. Coupling Material: The choice of coupling material is crucial in applications with high shock and impact loads. Couplings made from robust materials, such as steel or alloy, provide better resistance to deformation and can handle higher impact forces compared to couplings made from less sturdy materials.
  2. Elastomer Spider: The elastomer spider is the central element of the jaw coupling and is responsible for absorbing shocks and vibrations. It is essential to select an elastomer spider with the appropriate hardness and resilience for the specific application. Harder elastomers can withstand higher loads but may transmit more vibration, while softer elastomers offer better shock absorption but have lower torque capacity. Choosing the right elastomer hardness is a trade-off between shock absorption and torque transmission requirements.
  3. Operating Conditions: Consider the operating conditions, such as the frequency and magnitude of shock and impact loads, when selecting a jaw coupling. For applications with intermittent or occasional shock loads, standard jaw couplings with moderate shock absorption capabilities may suffice. However, for continuous or severe shock loads, specialized high-torque jaw couplings with enhanced shock absorption properties might be more suitable.
  4. Regular Maintenance: In high shock and impact load applications, it is crucial to perform regular maintenance and inspections to identify any signs of wear, fatigue, or damage to the coupling components. Regular maintenance ensures that the coupling remains in good working condition and minimizes the risk of unexpected failures due to excessive loading.
  5. Consider Alternative Couplings: While jaw couplings can handle certain levels of shock and impact loads, some applications with exceptionally high loads may require more specialized couplings, such as grid couplings, gear couplings, or disc couplings. These couplings are designed explicitly for heavy-duty applications with high shock and impact loads and can offer superior performance and reliability under such conditions.

In conclusion, jaw couplings can be used in applications with high shock and impact loads, but the specific coupling design, material, elastomer hardness, and operating conditions must be carefully considered. Proper selection, installation, and maintenance of the coupling are essential to ensure reliable performance and longevity in challenging operating environments with significant shock and impact loads.

Materials Used in Manufacturing Jaw Couplings

Jaw couplings are commonly made from various materials, each offering different properties and suitability for specific applications. Some of the commonly used materials include:

  • Polyurethane (PU): PU jaw couplings are known for their flexibility, high elasticity, and resistance to abrasion. They are ideal for applications requiring vibration dampening and shock absorption.
  • Aluminum: Aluminum jaw couplings are lightweight, corrosion-resistant, and have good thermal conductivity. They are commonly used in low-to-medium torque applications.
  • Steel: Steel jaw couplings offer high strength and durability, making them suitable for heavy-duty applications with high torque requirements.
  • Stainless Steel: Stainless steel jaw couplings are resistant to corrosion and are often used in applications where there is exposure to moisture, chemicals, or harsh environments.
  • Bronze: Bronze jaw couplings are known for their excellent wear resistance and low coefficient of friction, making them suitable for applications with high-speed and low lubrication.
  • Acetal: Acetal jaw couplings provide good chemical resistance and low moisture absorption, making them suitable for applications where chemical exposure is a concern.
  • Nylon: Nylon jaw couplings offer good strength, flexibility, and resistance to wear and chemicals, making them suitable for various industrial applications.

The choice of material depends on factors such as torque requirements, environmental conditions, operating speeds, and budget considerations. Engineers and designers select the appropriate material to ensure that the jaw coupling can perform optimally and withstand the demands of the application.
