95 RRL Coupling

An RRL Jaw Coupling, also known as a spider coupling or elastomeric coupling, is a type of flexible coupling used to connect two shafts and transmit torque while accommodating misalignment and dampening vibrations. These couplings are commonly used in various industrial applications where flexibility and shock absorption are necessary. Here’s a description of the key components and characteristics of an RRL Jaw Coupling:

• Hubs: An RRL Jaw Coupling consists of two hubs, one for each shaft to be connected. These hubs are typically made of metal, such as steel or aluminum, and have a jaw-like profile with curved or lobed sections that fit into the flexible element.
• Spider or Elastomeric Element: The flexible element in the RRL Jaw Coupling is usually made of an elastomeric material, such as natural rubber or synthetic rubber compounds. This element resembles a spider with multiple arms or lobes that extend between the hubs. The elastomeric material provides flexibility and absorbs shocks and vibrations.
• Jaw Design: The hubs have matching jaw profiles that fit into the flexible element’s lobes. When the hubs are connected, the jaws interlock with the lobes of the elastomeric element. This design allows for torque transmission while accommodating angular, parallel, and axial misalignment between the connected shafts.
• Fasteners: Typically, bolts and fasteners are used to secure the hubs to the shafts and clamp them onto the elastomeric element. Proper tightening of these fasteners is essential for the coupling’s effectiveness.
• Misalignment Tolerance: RRL Jaw Couplings are known for their ability to tolerate misalignment between the connected shafts. They can accommodate angular misalignment, parallel misalignment, and axial misalignment, helping to reduce stress on connected machinery.
• Vibration Damping: The elastomeric element’s flexibility allows it to dampen vibrations generated by the connected equipment. This feature helps protect the machinery from excessive wear and tear.
• Maintenance: RRL Jaw Couplings typically require minimal maintenance. Periodic inspection of fasteners and the condition of the elastomeric element is usually sufficient to ensure proper functioning.
• Load Capacity: These couplings come in various sizes and configurations to match the torque and load requirements of different applications. The load capacity of an RRL Jaw Coupling depends on factors such as the size of the coupling and the material properties of the elastomeric element.
• Application: RRL Jaw Couplings are commonly used in a wide range of industrial applications, including pumps, compressors, conveyor systems, fans, and other machinery where flexibility, shock absorption, and torque transmission are essential.

In summary, an RRL Jaw Coupling is a flexible coupling mechanism that uses an elastomeric element to connect two shafts, allowing for misalignment tolerance and vibration damping. These couplings play a crucial role in ensuring the smooth and reliable operation of various industrial machines and equipment.
