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.

Reducing Downtime and Maintenance Costs with Jaw Couplings

Jaw couplings play a crucial role in reducing downtime and maintenance costs in mechanical systems. Here’s how they contribute to improved efficiency and cost-effectiveness:

• Shock Absorption: Jaw couplings feature an elastomeric spider between the hubs, which acts as a shock absorber. It helps dampen vibrations and shock loads, protecting connected equipment from sudden impacts. By minimizing the impact of shocks and vibrations, jaw couplings extend the lifespan of components and reduce the need for frequent repairs or replacements.
• Misalignment Compensation: In real-world applications, shaft misalignment is almost unavoidable due to factors such as temperature variations, foundation settling, or minor assembly errors. Jaw couplings can accommodate angular and parallel misalignment, reducing stress on connected equipment and minimizing wear on shafts and bearings.
• Fail-Safe Design: Jaw couplings are designed with a fail-safe feature. If the elastomeric spider fails due to wear or damage, the jaws of the coupling interlock, allowing the system to continue transmitting torque. This design prevents complete coupling failure and allows the machinery to keep running until scheduled maintenance can be performed.
• Easy Installation and Replacement: Jaw couplings are relatively easy to install and replace, which helps reduce downtime during maintenance or equipment upgrades. With simple set-screw or clamp-type hubs, the couplings can be quickly installed or removed without disassembling the entire system.
• Cost-Effectiveness: Compared to some other types of couplings, jaw couplings are generally more cost-effective. They offer reliable performance and misalignment compensation at a relatively lower cost. Additionally, the extended equipment lifespan and reduced maintenance needs contribute to long-term cost savings.

By providing shock absorption, misalignment compensation, fail-safe operation, easy installation, and cost-effectiveness, jaw couplings enhance the overall reliability and efficiency of mechanical systems, leading to reduced downtime and maintenance costs.

How does a jaw coupling help in power transmission efficiency?

A jaw coupling plays a significant role in enhancing power transmission efficiency in mechanical systems. It achieves this by incorporating several design features that minimize energy losses and maximize the transfer of power from one shaft to another. Here are some ways in which a jaw coupling helps improve power transmission efficiency:

1. Mechanical Flexibility: Jaw couplings utilize a flexible elastomer spider as the connecting element between the two shafts. This elastomer spider allows for a certain degree of angular and parallel misalignment between the shafts without imposing significant additional loads on the connected equipment. The mechanical flexibility of the elastomer helps reduce the generation of excess heat and vibration, thereby optimizing power transmission efficiency.
2. Vibration Damping: The elastomer spider in a jaw coupling also acts as a vibration-damping element. It absorbs and dissipates vibrations generated during the operation of rotating machinery. By dampening vibrations, the coupling reduces energy losses due to mechanical oscillations, which can otherwise decrease the overall power transmission efficiency.
3. Shock Absorption: In addition to damping vibrations, jaw couplings can handle sudden shocks and impacts that may occur during equipment operation. The elastomer spider’s ability to absorb shocks prevents sudden force spikes from propagating through the system and helps maintain steady power transmission, thus improving overall efficiency.
4. Reduced Friction: The design of jaw couplings minimizes sliding friction between the shafts and the coupling components. This reduced frictional resistance results in lower energy losses and less heat generation during power transmission, contributing to higher efficiency in the system.
5. Torsional Wind-Up Compensation: When torque is transmitted through the shafts, there can be some degree of torsional wind-up or twist in the coupling. Jaw couplings can compensate for this torsional movement, ensuring that the transmitted power reaches the intended equipment without significant losses due to torsional deformation.
6. Simple and Robust Design: Jaw couplings have a simple construction, typically consisting of two hubs and an elastomer spider. This straightforward design reduces the number of moving parts and potential points of failure, resulting in a robust and reliable coupling. A reliable coupling minimizes the risk of power losses due to mechanical inefficiencies or breakdowns, thus improving overall power transmission efficiency.

In summary, a jaw coupling enhances power transmission efficiency by providing mechanical flexibility, vibration damping, shock absorption, reduced friction, and torsional wind-up compensation. Its simple and robust design further contributes to reliable power transmission. When selecting a jaw coupling for a specific application, it is essential to consider factors such as torque requirements, operating conditions, and misalignment compensation to ensure optimal efficiency and performance in the system.

Maintenance Requirements for Jaw Couplings

Jaw couplings are relatively low-maintenance components, but regular inspections and preventive measures can help ensure their optimal performance and longevity. Here are the maintenance requirements for jaw couplings:

• Visual Inspections: Regularly inspect the jaw coupling for signs of wear, damage, or misalignment. Look for cracks, chips, or deformation in the elastomeric spider, hubs, and other components.
• Lubrication: Some jaw couplings require periodic lubrication of the elastomeric spider to prevent dry rot and ensure flexibility. Refer to the manufacturer’s guidelines for the appropriate lubrication schedule and type.
• Tighten Fasteners: Check and tighten all fasteners, including set screws, regularly to prevent coupling slippage and maintain a secure connection between the shafts and hubs.
• Alignment: Ensure that the shafts connected by the jaw coupling are properly aligned. Excessive misalignment can lead to premature wear and failure of the elastomeric spider.
• Replace Worn Parts: If any component of the jaw coupling shows signs of wear beyond acceptable limits, promptly replace it to avoid further damage and potential system failure.
• Operating Conditions: Monitor the operating conditions of the machinery to prevent overheating or overloading, which can affect the performance and life of the coupling.

Following these maintenance practices can extend the life of the jaw coupling, reduce the risk of unexpected failures, and contribute to the overall reliability of the mechanical system.
