R+W disc pack couplings are designed to provide reliable and maintenance-free performance for a variety of industrial applications. The Series LP disc pack couplings feature six-hole plates made from highly elastic spring steel. High-strength bolts secure the disc packs to end hubs and spacers, transmitting torque through friction force. This design prevents micro movements within joints, increasing torsional stiffness. These disc packs compensate for angular and axial misalignment, while dual flex versions also handle lateral misalignment. Here are the main points:

• Fatigue Resistant and Wear Free: Designed for an infinite service life if operated within technical limits.

• Fit Clearance: Overall shaft/hub clearance ranges from 0.01 to 0.05 mm.

• Temperature Range: Operates effectively between -30 to +280° C.

• Torque Transmission: Transmits torque across disc pack assemblies purely by friction, avoiding stress concentration, backlash, and micro-movements.

• High Torsional Stiffness: Enhanced stiffness due to the friction-based torque transmission.

• Applications: Suitable for various applications, including steel mills, printing machinery, centrifugal pumps, and test rigs.

• Misalignment Compensation: Single flex configurations support radial loads, while dual flex configurations compensate for lateral misalignment.

• Backlash-Free: Uses high-strength screws to clamp the disc pack faces, ensuring reliable torque transmission and preventing micro-movements.

• Optional Ball-Detent Clutches: Available to prevent machine damage by disengaging in case of torque overloads.

• Additional Features:
  • High torsional stiffness
  • Wear and maintenance-free
  • Easy installation
  • Available in single and double flex designs
  • API 610 pump versions available for specific applications

Disc pack couplings offer robust, torsionally rigid solutions for high torque transmission and misalignment compensation in demanding industrial environments.
