1. Disc Coupling Overview

A disc coupling is a type of flexible coupling that consists of two hubs and a series of flexible disc packs. These disc packs are made of high-strength stainless steel, providing excellent torque transmission while accommodating misalignments and compensating for angular, parallel, and axial displacements.

2. Benefits of Rexnord Disc Couplings

Rexnord disc couplings offer several advantages over traditional couplings:

  • High Torque Capacity: The unique disc pack design allows for high torque transmission, ensuring efficient power transfer.
  • Flexibility: The disc packs provide flexibility to accommodate misalignments and reduce stress on connected equipment.
  • Damping Capability: The disc packs act as dampers, absorbing vibrations and reducing noise levels.
  • Maintenance-Free: Rexnord disc couplings are designed for long-term reliability and require minimal maintenance.
  • Compact Design: The compact size of disc couplings allows for easy installation in tight spaces.

3. Selecting and Customizing Disc Couplings

When selecting or customizing a disc coupling, it is essential to consider the following parameters and practical conditions:

  • Torque Capacity: Determine the required torque capacity based on the connected equipment and application demands.
  • Shaft Size: Select the appropriate disc coupling size to match the shaft diameter of the connected equipment.
  • Operating Speed: Consider the rotational speed requirements to ensure the disc coupling can handle the desired RPM.
  • Misalignment Tolerance: Determine the expected misalignments (angular, parallel, axial) to choose a disc coupling with the appropriate misalignment compensation capability.
  • Environmental Conditions: Evaluate factors such as temperature, humidity, and chemical exposure to select a disc coupling suitable for the working environment.
