rexnord grid coupling


Rexnord grid coupling is a highly efficient and reliable coupling system that is widely used in various industrial applications. This innovative coupling technology provides exceptional performance and durability, making it an ideal choice for demanding environments.

1. Introduction to Rexnord Grid Coupling

The Rexnord grid coupling is designed to transmit torque while compensating for misalignment and absorbing shock loads. It consists of a grid assembly, hub, and cover, all of which work together to provide a flexible and reliable power transmission solution.

2. Grid Coupling Construction

The grid coupling assembly is made up of a series of flexible grids arranged in a circular pattern. These grids are designed to flex under torque, allowing for angular and parallel misalignment compensation. The hubs are connected to the grid assembly, and the cover provides protection and containment of the grid elements.

3. Benefits of Rexnord Grid Coupling

Rexnord grid coupling offers several advantages over traditional coupling systems:

  • High torque capacity: The grid coupling can handle high torque loads, making it suitable for heavy-duty applications.
  • Misalignment compensation: The flexible grids allow for angular and parallel misalignment, reducing stress on the connected equipment.
  • Shock load absorption: The grid coupling can absorb shocks and vibrations, protecting the connected machinery from damage.
  • Long service life: The robust construction and high-quality materials ensure long-lasting performance and minimal maintenance requirements.
  • Easy installation: The grid coupling can be easily installed and aligned, reducing downtime and installation costs.

How Does a Grid Coupling Work?

A grid coupling operates by transmitting torque from one shaft to another while accommodating misalignment and absorbing shocks and vibrations. As the driving shaft rotates, it transfers torque to the grid assembly, which flexes and transmits the torque to the driven shaft. The flexibility of the grids allows for angular and parallel misalignment, ensuring smooth and reliable power transmission.

Choosing and Customizing the Right Grid Coupling

When selecting or customizing a grid coupling, it is important to consider various parameters and practical conditions. The following points should be taken into account:

  1. Torque requirements: Determine the torque capacity needed for the specific application.
  2. Misalignment tolerance: Evaluate the expected angular and parallel misalignment and choose a coupling that can accommodate it.
  3. Shaft sizes and types: Consider the diameter and type of the shafts to ensure proper fit and connection.
  4. Environmental factors: Assess the operating conditions, such as temperature, humidity, and presence of corrosive substances, and select a coupling that can withstand these conditions.
  5. Application-specific requirements: Take into account any specific requirements or constraints of the application, such as space limitations or regulatory compliance.

Installation of a Grid Coupling

The installation process of a grid coupling involves the following steps:

  1. Prepare the shafts: Clean and inspect the shaft ends to ensure they are free from dirt, rust, or other contaminants.
  2. Mount the hubs: Attach the hubs to the shaft ends using the appropriate mounting method, such as a keyway or set screws.
  3. Install the grid assembly: Place the grid assembly between the hubs, ensuring proper alignment and engagement with the grids.
  4. Secure the cover: Position the cover over the grid assembly and secure it to the hubs using the provided fasteners.
  5. Check alignment: Verify that the coupling is properly aligned and adjust if necessary.
  6. Tighten fasteners: Ensure all fasteners are properly tightened according to the manufacturer’s specifications.
