Our L-Series jaw couplings are meticulously designed to accommodate a vast array of bore, key, and spline options, making them perfect for a wide range of applications powered by both electric motors and internal combustion engines. This innovative design offers an exemplary shaft-to-shaft connection that is ideal for numerous industrial applications. Additionally, our jaw couplings are fully interchangeable with other popular domestic brands, offering seamless integration into your existing systems.
By introducing this product to our already extensive lineup of power transmission solutions, we empower our customers with a diverse and cost-effective selection. Crafted from sintered iron, these couplings are available with a variety of drive elements including Buna-N, Urethane, and Hytrel, ensuring durability and adaptability in various environments.
Jaw couplings, esteemed for their versatility, serve as an all-purpose industrial power transmission solution. They adeptly handle a wide temperature range, manage angular misalignment and its resultant loads, resist harsh chemicals, and exhibit superior speed and dampening capabilities. Comprising three primary parts-two hubs typically bored to a clearance fit tolerance, and an elastomeric insert-these couplings are designed for longevity, although the inserts, also known as spiders, will eventually require replacement.
In the event of insert failure, the coupling's innovative fail-safe design ensures continued operation. The hubs interlock to maintain load carrying capacity, albeit without the damping benefits provided by the insert. This allows operators a critical window to safely shut down the system. However, once an insert fails, it's imperative to replace both the insert and hubs promptly, as wear from hub-on-hub contact renders them unsuitable for further use. Continuous operation without an insert is not advised.
Remarkably, these jaw couplings function efficiently without lubrication. Unlike gear, grid, or chain couplings that necessitate regular greasing, a jaw coupling requires no additional maintenance provided the insert remains intact, ensuring hassle-free reliability.
Traditional jaw couplings excel in transmitting torque through their elastomeric flexing element, which operates in compression. This method is favorable because elastomers are more resilient to handling stress and load in compression, including peak loads, than in other motion types, providing superior torque transmission.
Our standard jaw-coupling insert is crafted from solid Nitrile Butadiene (Buna N) rubber, a flexible elastomer known for its oil resistance, resilience akin to natural rubber, and ability to operate across temperatures from -40° to 212°F (-40° to 100°C). Ideal for cyclic loads, it boasts a shore hardness of 80A, high dampening capacity, and robust chemical resistance.
The open center variation of the Buna N rubber insert offers unique advantages. While the closed center version provides a more robust design for high-speed applications, it does not permit very close shaft separation. Conversely, the open center spider is engineered for situations where shaft ends must be extremely close, offering a solution where the center section is not feasible.
A third ingenious variation includes an insert that wraps around the coupling's exterior, secured by a retaining ring. This allows for effortless replacement without shifting the hubs on the shaft. However, it is typically limited to lower RPM speeds, sometimes as low as 1750 RPM, depending on the design.
In addition to the standard Buna N inserts, materials such as urethane, Hytrel, and Bronze are also favored. Urethane, for instance, offers enhanced torque capacity-approximately 1.5 times greater than Buna N-though it provides less dampening. Its operational temperature range is narrower (-30° to 160°F, -34° to 71°C), and while it resists oil and chemicals, it is not ideal for cyclic or start/stop applications.
Our Hytrel inserts stand as a testament to engineering excellence, crafted meticulously to cater to high torque and high-temperature applications ranging from a chilly -60° to a scorching 250°F (-51° to 121°C). These inserts exhibit outstanding resistance to oil and chemicals, ensuring longevity and performance even in the most demanding environments. However, they are not advised for cyclic or start/stop applications and are generally restricted to a half-degree of angular misalignment. In comparison, Buna N and Urethane allow for a broader range of 1 degree. Despite this, the Hytrel inserts maintain a similar capability in managing parallel misalignment, equivalent to that of Buna N & Urethane inserts, at approximately 0.015 in.
Designed for durability, our rigid, porous oil-impregnated bronze inserts excel in slow-speed applications, with a maximum limit of 250 RPM. These inserts are powerhouses of torque and show remarkable resilience to extreme temperatures, spanning from a frigid -40° to a blistering 450°F (-40° to 232°C). They remain unaffected by water, oil, or dirt, ensuring consistent performance. Angular misalignment capability mirrors that of Hytrel inserts, generally at a half-degree, yet parallel misalignment handling sees a slight reduction to 0.010 in, making them perfect for specific high-torque scenarios.
Jaw couplings, while versatile, have their operating temperature governed by the elastomeric insert. They offer moderate capabilities in handling misalignment, both angular and parallel. Yet, certain applications might demand more. The high radial stiffness can cause significant reactionary loads, and vertical setups might necessitate specialized hubs if the setscrew fails to secure the hubs effectively. Traditional jaw couplings aren't ideal for motion control applications due to inherent looseness between the jaws and elastomer, which tends to compress gradually over time, affecting precision.
Curved jaw couplings distinguish themselves with elegantly contoured teeth, a favored design in Europe and widely embraced in motion control applications. By utilizing a highly stiff urethane insert, they can achieve a backlash-free coupling, sometimes referred to as GS or Spidex couplings. This innovative design offers precision and reliability. However, one limitation is their inability to transform into an in-shear design due to the inherent curvature of the jaws.
