Product Picture

 

 

 

 
 

These stainless steel shaft couplers allow you to couple 2 size shafts together. They can be used for connecting motor shafts to drive shafts, or 2 different-sized shafts. These shaft couplers have a length of 0.75″, a outer diameter of 0.42″, and couple 1/4″ to 5mm shafts.

Connect this to that with a set-screw coupler. These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to 2 shafts even if they are not perfectly co-linear and will help reduce binding effects.  

 

This coupler will connect a 5mm diameter shaft to an 8mm diameter shaft.  A perfect add on for motors . Comes with 2 sets of double set-screws (two per side) for secure attachment. You’ll need a 2mm allen wrench to tighten/loosen the set-screws.

Minimizing Wear and Tear on Connected Components with Jaw Couplings

A jaw coupling plays a critical role in minimizing wear and tear on connected components by providing several key benefits:

  • Shock Absorption: Jaw couplings have a flexible elastomeric element between the two hubs, which acts as a cushion and absorbs shocks and vibrations. When the connected machinery experiences sudden jolts or impacts, the jaw coupling helps dampen these forces, protecting the equipment from damage and reducing wear on components.
  • Misalignment Compensation: In mechanical systems, misalignment between shafts is a common issue that can lead to premature wear on components. Jaw couplings can tolerate a certain degree of angular, parallel, and axial misalignment, allowing for better alignment between the driving and driven components. This feature helps distribute forces more evenly and reduces stress on connected components.
  • Resilience to Overloads: Jaw couplings can withstand temporary overloads, such as starting torque or sudden load spikes, without causing damage to the connected equipment. The elastomeric element of the jaw coupling acts as a torque limiter, protecting the machinery from excessive loads and preventing wear and tear.
  • Backlash Prevention: Backlash, which is the play or clearance between mating gears or components, can cause impact forces during reversing motions. Jaw couplings offer low backlash performance, reducing the potential for impact and minimizing wear on gears and other components.
  • Reduced Maintenance: By providing shock absorption, misalignment compensation, overload protection, and low backlash, jaw couplings help extend the service life of connected components. This, in turn, reduces the frequency of maintenance and replacement, leading to cost savings and increased productivity.
  • Smooth Power Transmission: Jaw couplings transmit power smoothly between the driving and driven shafts, resulting in less stress on components. The torsional flexibility of the elastomeric element helps prevent abrupt torque spikes, contributing to improved component longevity.

Overall, the jaw coupling’s ability to absorb shocks, compensate for misalignment, handle overloads, and provide smooth power transmission makes it an effective solution for minimizing wear and tear on connected components. Regular inspection and maintenance of the jaw coupling are still essential to ensure its optimal performance and extend the life of the entire mechanical system.

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.

Types of Jaw Coupling Designs

Jaw couplings come in various designs to meet different application requirements. The main types include:

  • One-Piece Jaw Coupling: This design consists of a single piece of material, typically made of steel or aluminum. It offers simplicity and compactness, making it suitable for light to medium-duty applications.
  • Two-Piece Jaw Coupling: This design features two separate hubs with a flexible spider placed in between. The two-piece design allows for easier assembly and disassembly, making it convenient for maintenance and replacement of the elastomeric spider.
  • Three-Piece Jaw Coupling: In this design, the coupling includes three parts: two hubs and an insert. The hubs are typically made of metal, while the insert is an elastomeric element (spider). Three-piece jaw couplings provide better damping of vibrations and are commonly used in applications where vibration isolation is crucial.
  • Customizable Jaw Coupling: Some manufacturers offer customizable jaw couplings, allowing customers to choose different hub styles, materials, and spider hardness to tailor the coupling’s performance for specific applications.

Each design has its advantages and is selected based on factors such as torque requirements, misalignment compensation, and ease of maintenance.
