A jaw coupling is a type of mechanical power transmission coupling that is used to transmit torque between two shafts that are not aligned with one another. It consists of two hubs that are connected by a flexible element, typically made of elastomeric material such as rubber or polyurethane. The hubs have projecting jaws or teeth that engage with the flexible element, which allows them to transmit torque while still allowing for some misalignment between the shafts. Jaw couplings are commonly used in industrial and commercial applications where there is a need for flexible, low-maintenance power transmission. They are particularly useful in applications where the shafts are subject to angular, parallel, or axial misalignment.
Here are some advantages of using jaw couplings:
Misalignment tolerance: As mentioned, the flexible element allows for some misalignment between the two shafts, which can be helpful in applications where the shafts are not perfectly aligned.
Vibration damping: The flexible element also helps to absorb and dampen vibrations, which can be beneficial in applications where vibration is an issue.
Easy to install: Jaw couplings are relatively simple to install and do not require precise alignment. They can be easily removed and replaced if necessary.
No maintenance: Jaw couplings do not require any maintenance and have a long lifespan.
Cost-effective: Jaw couplings are generally less expensive than other types of couplings, such as rigid or bellows couplings.
Overall, jaw couplings are a good choice for applications that require some misalignment tolerance, vibration damping, and low maintenance. They are widely used in a variety of industries, including manufacturing, automotive, and aerospace.
Original Jaw Couplings:This simple three piece premium flexible jaw coupling is commonly used to connect electric motors to hydraulic pumps or mechanical drives. The hubs are made of strong, lightweight aluminum alloy. The body and lugs are precision machined on CNC equipment to ensure a proper fit every time. Two set screws are standard. Solid rubber walls in the insert eliminate metal-to-metal contact and provide clean, quiet, trouble-free performance when properly aligned.
L-Series Jaw Couplings: L-series jaw couplings are a type of mechanical coupling that is designed to transmit torque and rotational power between two shafts that are not aligned. They are commonly used in applications where shaft misalignment is present, such as in pumps, motors, and gearboxes. L-series jaw couplings consist of two hubs that are connected by a flexible elastomeric element, which allows the hubs to move slightly relative to each other and absorb any misalignment between the shafts. This allows the coupling to transmit torque smoothly and efficiently, while protecting the shafts and other components from damage due to misalignment. L-series jaw couplings are available in a range of sizes and materials, and can be used in a variety of industrial and commercial applications, including conveyor systems, material handling equipment, and power transmission systems.
Curved Jaw Couplings: Curved jaw couplings, also known as curved-tooth or curvilinear couplings, are a type of mechanical coupling used to transmit torque and rotational power between two shafts that are not aligned. They are similar to traditional jaw couplings in that they consist of two hubs connected by a flexible elastomeric element, but the element has a curved shape that allows for greater misalignment between the shafts. This makes curved jaw couplings well-suited for applications with large amounts of misalignment or where the shafts may experience frequent movement or shifting. They are commonly used in a variety of industrial and commercial applications, including pumps, motors, and gearboxes, and are available in a range of sizes and materials to suit different application requirements.
Keyed connection: In this type of connection, the hub has a keyway cut into it, and the shaft has a matching key. The key is inserted into the keyway and prevents the hub from turning relative to the shaft.
Splined connection: In this type of connection, the hub has splines cut into it, and the shaft has a matching spline. The splines interlock, allowing the hub to rotate with the shaft but preventing it from sliding axially.
Clamped connection: In this type of connection, the hub is secured to the shaft using a clamping mechanism, such as a set screw or a clamping collar. The clamping force holds the hub in place on the shaft.
We carry a full line of standard jaw couplings to meet the various needs of the power transmission and precision machinery markets. Huading offers a custom service that can produce custom jaw couplings from your drawings. Custom jaw couplings are couplings that are designed to meet specific requirements or specifications for a particular application. These couplings may have different sizes, materials, or features than standard couplings, and they may be designed to meet specific performance or operational requirements. Custom jaw couplings can be made from a variety of materials, including aluminum, steel and they may be designed with features such as keyways, flats, or setscrews.
There are several factors to consider when designing custom jaw couplings, including the torque and speed of the application, the alignment and misalignment tolerances of the shafts, the environmental conditions in which the coupling will be used, and the overall cost of the coupling. It is important to work with a reputable manufacturer or supplier of custom jaw couplings to ensure that the coupling meets the required specifications and performs as expected in the application.
